Oviposition site preference of Plutella xylostella (L.) and the parasitism by Trichogramma pretiosum Riley on cabbage plants at pre- and post-head formation were investigated in commercial cabbage field. Groups of six plants were randomly caged. In each cage three pairs of 24h-old P. xylostella moths were released, followed by 1,200 T. pretiosum females released 12h later. After 48h from parasitoid release, plants were harvested and fully inspected with the oviposition mapped according to the leaf position and their parts (basal, median and border) and upper and bellow leaf surfaces. Moth oviposition and egg parasitism were equally distributed across the plant leaves at the pre-head formation stage. At this stage, the basal part and the upper leaf surface...

Provedor de dados: 82
Autores: Rocha,Luciane da; Moreira,Gilson R.P.; Redaelli,Luiza R.
With the aid of scanning electron microscopy, the external morphology and distribution of the antennal sensilla were described for females of Gryon gallardoi (Bréthes), an egg-parasitoid of coreids. The geniculated and clavated antennae are composed of 12 antennomeres. Along the flagelum we registered dorsal glands and seven types of sensilla: papillary, chaetica of two sizes - long and short types, styloconic grooved-peg, sickle-shaped and trichodea with numerical and spatial variation among the flagellomeres. Functional aspects of the sensilla are discussed in the context of G. gallardoi antennal drumming behavior. Thus, the determination and the description pattern of antennal sensilla in G. gallardoi, in the present study, is an advance regarding the...

Methodology of mass multiplication of Telenomus podisi Ash. and Trissolcus basalis (Woll.) (Hymenoptera: Scelionidae) on eggs of Euschistus heros (Fab.) (Hemiptera: Pentatomidae)
Provedor de dados: 82
Autores: Peres,Wilsimar A.A.; Corrêa-Ferreira,Beatriz S.
Laboratory studies were carried out to develop a methodology for the mass production of Telenomus podisi Ash. and Trissolcus basalis (Woll.) on eggs of Euschistus heros (Fabr.) and to compare it with the methodology presently used in the biological control program of soybean stink bugs in Brazil [T. basalis reared on Nezara viridula (L.) eggs]. In a first experiment, egg masses randomly distributed were shown the most adequate method of exposure of E. heros to parasitism. In a second experiment, egg masses of E. heros were randomly glued on cardboard cards and exposed to parasitism by T. podisi and T. basalis. The parasitoids multiplied on E. heros eggs showed parasitism (ca. 99%) similar to that observed with T. basalis reared on N. viridula eggs (99.7%)....

Trichogramma in Brazil: feasibility of use after twenty years of research
Provedor de dados: 82
Autores: Parra,José R.P.; Zucchi,Roberto A.
Results of studies with Trichogramma in Brazil are presented, especially those developed at ESALQ/USP in the past two decades (1984-2004). The project involved taxonomy, rearing techniques, biological and behavioral aspects of the pests and parasitoids, pest population dynamics, release techniques, selectivity studies, and efficiency evaluation. It can be considered a model project and has been adopted by other biological control programs in Brazil and Latin America. The program has given rise to a number of publications, allowing the formation of human resources in this area and opening new research areas. The results indicated that the parasitoid can be used to control key pests in cotton, sugarcane, stored grain, vegetables, corn, soybean, and tomato....

Selectivity of neem to Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis (Hymenoptera: Trichogrammatidae)
Provedor de dados: 82
Autores: Hohmann,Celso L; Silva,Flávia A C; Novaes,Tanara G de.
Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis are commonly found in avocado and persimmon orchards in northern Parana state. However, their abundance depends on whether insecticides are used or not to control the key lepidopteran pests Stenoma catenifer (Wals.) (Lepidoptera: Elachistidae) and Hypocala andremona (Stoll) (Lepidoptera: Noctuidae), respectively. The aim of this work was to evaluate the effects of an aqueous neem seed extract (ANSE) at 15, 3 and 1.5%, and of an emulsifiable concentrate neem oil (ECNO) at 2.5, 0.5 and 0.25% on lifetime parameters of these trichogrammatids as a way of testing the feasibility of integrating the biological and chemical control methods. Chemicals were applied on Anagasta kuehniella (Zeller)...

The effects of the egg density of Diaphania hyalinata (L.) on several biological parameters of Trichogramma exiguum Pinto &amp;amp; Platner and T. pretiosum Riley were investigated. For that, 24h-old egg masses were isolated in glass tubes (15 replicates; 1 egg mass = 1 replicate), and offered to parasitization by a newly-emerged female of T. pretiosum or T. exiguum 24h at the proportion of one female to 5, 10, 15, 20, 25, 30, 35 and 40 eggs of D. hyalinata. The following parameters were evaluated: number of parasitized eggs, number of individuals per egg, viability and sex ratio. Trichogramma exiguum parasitized more eggs than T. pretiosum when more than 25 eggs were available per female. The percentage of emergence was satisfactory to T. pretiosum in...

Effect of Wolbachia on the Survival and Reproduction of Trichogramma kaykai Pinto &amp;amp; Stouthamer (Hymenoptera: Trichogrammatidae)
Provedor de dados: 82
Autores: HOHMANN,CELSO L.; LUCK,ROBERT F.; STOUTHAMER,RICHARD.
Parthenogenetic inducing Wolbachia infections are particularly common in the genus Trichogramma, but the influence of the microrganism on parasitoids' fitness has received relatively little attention. The aim of this study was to determine the effects of the bacteria on the survival and reproduction of Trichogramma kaykai Pinto &amp;amp; Stouthamer, comparing an infected line (thelytokous) with an antibiotically cured (arrhenotokous) line, both reared on Trichoplusia ni Hübner eggs. Cured wasps produced significantly more progeny and more daughters than Wolbachia-infected wasps. Significantly more wasps emerged per host when parasitized by the arrhenotokous females than by the thelytokous females. Cured females, however, lived significantly less than...

Effects of egg age of Spartocera dentiventris (Berg) (Hemiptera: Coreidae) on parasitism by Gryon gallardoi (Brethes) (Hymenoptera: Scelionidae)
Provedor de dados: 82
Autores: Rocha,Luciane da; Kolberg,Roberta; Mendonça Jr.,Milton de S.; Redaelli,Luiza R.
To evaluate the effect of egg age of Spartocera dentiventris (Berg) on the parasitism by Gryon gallardoi (Brethes), groups of 12 eggs of 2, 3, 4, 5, 6, 7, 8, and 12 days old were exposed to one female of G. gallardoi on a test tube, with the wasp observed for 2h subsequently. Later, the eggs were individualised and incubated (25 ± 1°C; 12h photoperiod) until adult emergence. To identify the preferred age, groups of 12 eggs of 1, 3, 5, 7 and 12 days of age were simultaneously exposed to a parasitoid female on an arena for 2h. These groups were also individualised and incubated until parasitism was confirmed. On all ages tested parasitism was at about 88.5 ± 2.64%, with a reduction in adult parasitoid emergence with age increasing (P &lt; 0.01). The...

Autores: Xavier,Luciane Modenez Saldivar; Laumann,Raúl Alberto; Borges,Miguel; Magalhães,Diego Martins; Vilela,Evaldo Ferreira; Blassioli-Moraes,Maria Carolina.
The objective of this work was to evaluate if corn plants damaged by the lesser cornstalk borer (Elasmopalpus lignosellus) larvae release volatile organic compounds capable of attracting the egg parasitoid Trichogramma pretiosum. The treatments consisted of plants subjected to harm caused by E. lignosellus larvae, plants subjected to mechanical damage, and undamaged plants. The parasitoid was more attracted by the volatiles released by the insect damaged plants than to those released by undamaged corn plants, after 24 and 72 hours. The volatiles (Z)-3-hexenyl acetate, β-pinene, β-myrcene, (E)-4,8-dimethylnona-1,3,7-triene, and benzothiazole were released in significantly larger quantities by damaged plants. Volatiles released by corn plants damaged by E....

Euschistus heros mass rearing technique for the multiplication of Telenomus podisi
Provedor de dados: 86
Autores: Silva,Cleonor Cavalcante; Laumann,Raul Alberto; Blassioli,Maria Carolina; Pareja,Martin; Borges,Miguel.
The objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively. Survival rate of immature stages and survivorship and reproduction of adults were determinated. Survivorship of nymph to adult was the highest (89%) at density 100 eggs per dish. Adult survivorship was independent of density, and 100 couples per cage were the best to improve quality of the produced progeny. In these conditions, fecundity was 160.8±9.28 eggs per female, and a total of 8,950±456 eggs per cage per month was produced. Two hundred couples per cage showed a negative...

Functional response of Trichogramma pretiosum on Trichoplusia ni eggs at different temperatures and egg densities
Provedor de dados: 86
Autores: Milanez,André Malacarne; Carvalho,José Romário de; Lima,Victor Luiz Souza; Pratissoli,Dirceu.
Abstract: The objective of this work was to determine the functional response of the parasitoid Trichogramma pretiosum on Trichoplusia ni eggs at different temperatures (20, 25, and 30ºC) and egg densities (5, 10, 15, 20, 25, and 30 eggs). The logistic regression showed a type-II functional response for all temperatures. The search efficiency of T. pretiosum was reported as 0.049±0.0019, 0.069±0.0042 and 0.068±0.0033 per hour, and the estimated handling times were 1.82±0.0424, 1.69±0.0398, and 1.54±0.0498 hour at 20, 25 and 30ºC, respectively. Females of Trichogramma pretiosum show greater efficiency at 30ºC and a type-II functional response. The parasitism rate decreases, when host density increases.

Effect of selectivity of herbicides and plant growth regulators used in sugarcane crops on immature stages of Trichogramma galloi (Hymenoptera: Trichogrammatidae)
Provedor de dados: 87
Autores: Oliveira,H.N.; Antigo,M.R.; Carvalho,G.A.; Glaeser,D.F.
Herbicides and plant growth regulators are often used in sugarcane management. However, the use of non-selective pesticides can cause adverse effects on the efficiency of beneficial insects in integrated pest management. Within this context, this study aimed to evaluate the effect of such products on the immature stages of the parasitoid Trichogramma galloi. Eggs of Diatraea saccharalis containing the parasitoid at the egg-larva stage and at the prepupal and pupal stages were immersed in test solutions of the following pesticides (maximum recommended doses for sugarcane): herbicides clomazone and diuron + hexazinone, and plant growth regulators trinexapac-ethyl and sulfometuron-methyl. The biological properties evaluated were emergence (F1 and F2) and...

Trichogramma acacioi (Hymenoptera, Trichogrammatidae) parasitism capacity at different temperatures and factitious hosts
Provedor de dados: 92
Autores: Pratissoli,Dirceu; Bueno,Adeney de Freitas; Bueno,Regiane Cristina Oliveira de Freitas; Zanúncio,José Cola; Polanczyk,Ricardo Antonio.
It was studied the parasitism capacity of Trichogramma acacioi on Anagasta kuehniella and Sitotroga cerealella eggs at different temperatures (15, 20, 25, 30 and 35 ± 1°C). The parasitism of T. acacioi varied with temperature and host. The highest parasitism (³80%) were observed during the first days after emergence in both hosts, at all tested temperatures. The accumulated parasitism varied with both host and temperature, being higher on A. kuehniella at 20°C, what shows good parasitoid species adaptation to this temperature. Thus, we conclude that the best host and best temperature to be used at mass-rearing of T. acacioi is A. kuehniella and 20ºC, respectively. Moreover, this Trichogramma species has great potential to be used in field releases at...

Effects of parasitoid and host age on the parasitism of Trichogramma pretiosum on eggs of Anticarsia gemmatalis
Provedor de dados: 92
Autores: Queiroz,Ana Paula de; Costa,Cintia Oliveira; Favetti,Bruna Magda; Silva,Gabriela Vieira; Bueno,Adeney de Freitas.
Abstract The ages of parasitoid females and their hosts can have substantial effects on parasitism and parasitoid efficacy. This relationship has been investigated over the last few decades and found to vary among species. To our knowledge, it was virtually unknown for Trichogramma pretiosum wasps that parasitize Anticarsia gemmatalis eggs. Therefore, the influence of parasitoid and host age on the parasitism of T. pretiosum on eggs of A. gemmatalis was here evaluated in three independent bioassays. Neither the number of parasitized eggs nor that of emerged parasitoids differed between T. pretiosum females of different age. The number of parasitoids per egg and the sex ratio were higher for 5-day-old females. Regarding host age, the number of parasitized...

Autores: Pomari-Fernandes,Aline; Bueno,Adeney de Freitas; Bortoli,Sérgio Antonio De.
ABSTRACT In two independent bioassays, size and flight ability of parasitoids reared on eggs of Corcyra cephalonica for 19 generations and parasitoids reared on a natural host (Spodoptera frugiperda eggs) for 250 generations were compared as fast quality control procedures for insect rearing. The size of parasitoids was examined by morphometric analysis using a stereoscope. Length and width of the wings, right hind tibia, and the body of 20 individuals (males and females) were measured. In the analysis of flight ability, parasitoids were divided into three groups: individuals able to fly ("flyers"), individuals that did not fly but had no visible deformation ("walkers"), and individuals with visible deformation ("deformed"). We observed that parasitoids...

Diatraea flavipennella (Box) (Lepidoptera, Crambidae) is one of the most destructive pests in sugarcane plantations in the Northeast Region of Brazil. Developmental characteristics and parasitism potential of the egg parasitoids Telenomus alecto Crawford (Hymenoptera, Scelionidae) and Trichogramma galloi Zucchi (Hymenoptera, Trichogrammatidae) were compared with the aim of selecting a suitable species for biological control of D. flavipennella. Both T. alecto and T. galloi developed well and were readily adapted to D. flavipennella eggs as host. Although, T. galloi presented higher viability, with more adults emerging per host egg and higher sex ratio, the developmental period (egg-adult) was shorter in T. alecto and female longevity was extended.

Impact of the number of Spodoptera frugiperda egg layers on parasitism by Trichogramma atopovirilia
Provedor de dados: 63
Autores: Beserra,Eduardo Barbosa; Parra,José Roberto Postali.
Egg parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) can be found in several crops attacking Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) eggs. It is therefore necessary to demonstrate the capacity of these natural enemies in suppressing populations of the pest to allow them to be used in biological control programs against that species. This work had the objective of evaluating the impact of egg layer distribution in S. frugiperda egg masses on the parasitism capacity of Trichogramma atopovirilia Oatman &amp;amp; Platner, 1983. Masses containing one, two, and three layers were used as treatments, and 1.6 parasitoid per egg of the pest were released. Parasitism percentage differences were observed among the three...

The parasitoid, Trichogramma spp. was produced using the rice moth eggs Corcyra cephalonica as host. Thus, the study of storage methods was done for the right timing of the parasitoid application during the pest out break. Various storage methods were studied by comparing different set of packed eggs in tissue paper and fire mesh, and unpacked eggs. The eggs were then stored at 5±2°C and 7±2°C for 1-4 weeks. The interaction between temperatures and packing methods resulted in the reduction of egg weight. At 5±2°C reduced fewer egg weight and more larval emergence than that at 7±2°C. Additional emergences were found more in packing eggs with tissue paper than fine mesh and unpacked. The one week storage eggs at both temperatures showed more than 80%...

 The European pepper moth Duponchelia fovealis (Zeller, 1847) (Lepidoptera: Crambidae), despite being among the principal pests of strawberries in Brazil. However, biological control methods are rarely documented for this pest. In the current study, the goal was to select promising Trichogramma strains to enable the control of D. fovealis and to determine the acceptance of different ages of host eggs by the parasitoid. In the first bioassay, evaluations were done on the biological parameters of five strains of Trichogramma pretiosum Riley and one of Trichogramma galloi Zucchi (Hymenoptera: Trichogrammatidae). The best performance came from the strains, Tp18 (T. pretiosum) and Tg (T. galloi), showing parasitism and viability higher than 50 and 90%,...

This study evaluated the parasitism of Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) on eggs of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) at different ages and densities. The rates of parasitism and emergence, the number of parasitoids emerged per egg and sex ratio of offspring were evaluated in both experiments. Eggs of H. armigera up to 36 hours provided greater parasitism and emergence of adults compared to eggs up to 60 hours old. The number of parasitoids, which emerged per host egg, was greater than one and the sex ratio remained around 80% of females, regardless of the egg development stage. Females of T. pretiosum responded with superior rates of parasitism, emergence and number of parasitoids per egg at the densities of...

Interspecific interaction between Telenomus remus (Hymenoptera: Platygastridae) and Trichogramma pretiosum (Hymenoptera: Trichogrammatidae) on Spodoptera frugiperda (Lepidoptera: Noctuidae) eggs
Provedor de dados: 42
Autores: Carneiro,Tatiana R.; Fernandes,Odair A.
This work aimes to evaluate the interspecific interaction between Trichogramma pretiosum and Telenomus remus, two biological control agents of fall armyworm (Spodoptera frugiperda) eggs. Eggs of Spodoptera frugiperda previously parasitized by Telenomus remus were offered to Trichogramma pretiosum, and those parasitized by Trichogramma pretiosum were offered to Telenomus remus. The previously parasitized eggs were tested at different embryonic development stages for each parasitoid. In addition, to evaluate the competition between species, Spodoptera frugiperda eggs were offered to the parasitoids simultaneously. The behavior of the insects was recorded under a stereomicroscope. When Spodoptera frugiperda eggs were previously exposed to either parasitoid,...

Trichogramma spp. (Hymenoptera: Trichogrammatidae) can control Diaphania hyalinata Linnaeus (Lepidoptera: Pyralidae). On the other hand, pesticides may reduce the efficiency of natural enemies. The objective was to evaluate the side-effects of fungicides used in the production of cucurbitaceous crops on Trichogramma atopovirilia Oatman &amp;amp; Platner parasitizing D. hyalinata eggs. The fungicides used in bioassays were: azoxystrobin (0.08 g active ingredient [ai] L-1), chlorothalonil (2.00 g ai L-1), mancozeb (1.60 g ai L-1), tebuconazole (0.25 g ai L-1) and thiophanate-methyl (0.49 g ai L-1). Cardboards with 30 D. hyalinata eggs previously immersedin fungicide solutions and distilled water (control) were offered separately to 20 newly emerged T....

Provedor de dados: 65
Autores: Faria,Cristina Arantes; Torres,Jorge Braz; Fernandes,Adriana Maria Vieira; Farias,Angela Maria Isidro.
One important factor determining the efficacy of parasitoids is the way they exploit different host patch. This study evaluated the response of females of Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) to the oviposition sites of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) on processing tomato plants. In fully developed caged tomato plants T. absoluta moths were released, followed by the release of T. pretiosum females 12h later. After 24h of parasitoid release, the moth oviposition sites were mapped according to the plant canopy, and levels of parasitism assessed. The parasitism rate varied from 1.5 to 28%. There was not influence of plant structures on parasitism, except for the absence of parasitism on the plant apex. Levels of...

Provedor de dados: 65
Autores: Querino,Ranyse Barboa; Silva,Nadja Nara Pereira da; Zucchi,Roberto Antonio.
ABSTRACT: The micro-hymenopterans of genus  Trichogramma are eggs parasitoids used in the biological control of lepidopteran pests. The objectives of this study was to record the interaction of species of  Trichogramma and their hosts on crops in the Mid-North, in the states of Maranhão and Piauí, Brazil. Lepidopteran eggs were sampled on crops and non-crops.  Trichogramma atopovirilia , T. manicobai ,  T. galloi and  T. pretiosum occur naturally in eggs of eight lepidopteran species. Natural parasitism shown by  Trichogramma species reveals the importance of these parasitoids as agents for biological control in the Mid-North region.
