Interaction betweeen Telenomus remus and Trichogramma pretiosum in the management of Spodoptera spp. The use of egg parasitoids is a promising strategy for Integrated Pest Management (IPM), but different species of parasitoids have greater or lesser control efficiency, depending on the pest species. Recently, not only Anticarsia gemmatalis and Pseudoplusia includens but also Spodoptera cosmioides and S. eridania have been among the key Lepidoptera larvae attacking soybeans. This study evaluated the combination of Telenomus remus and Trichogramma pretiosum for parasitism of eggs of the Spodoptera complex, for better control efficiency and broader spectrum of action among the key pests of soybeans. The experiment was carried out under controlled...

Host preference of the egg parasitoids Telenomus remus and Trichogramma pretiosum in laboratory. This research aimed to evaluate the host preference of the egg parasitoids Telenomus remus and Trichogramma pretiosum. Trials were carried out in laboratory, under controlled environmental conditions (25 ± 2ºC temperature; 70 ± 10% RH; and 14 h photophase). The parasitoid searching behavior was evaluated based on the distribution (%) of eggs parasitized by each parasitoid, on egg masses of each host species. Results showed the host preference of T. remus by Spodoptera cosmioides eggs. T. pretiosum, reared in A. gemmatalis eggs, choose to parasitize always eggs of the host where the parasitoid had been reared. The egg preference was not observed when T....

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...

Occurrence of Helicoverpa armigera (Hübner, 1808) on citrus in the state of Sao Paulo, Brazil
Provedor de dados: 94
Autores: Bueno,Regiane Cristina Oliveira de Freitas; Yamamoto,Pedro Takao; Carvalho,Marina Mouzinho; Bueno,Nádia Maebara.
The occurrence of Helicoverpa armigera (Hübner, 1808) was first reported in citrus orchard in the state of São Paulo (SP). High infestation levels of H. armigera were observed in October 2012, in the city of Botucatu, SP. The larvae was fed of all parts of the plants. The injuries on the leaves caused drastic reduction in the leaf area and the fruits attack occurred from an early stage of development to the ripe fruit. Thus, the first occurrence of H. armigera in this citrus culture adds to the list of hosts of this pest, and is of great importance, because it confirms H. armigera potential dispersion and polyphagia.

Photosynthetic response of soybean to twospotted spider mite (Acari: Tetranychydae) injury
Provedor de dados: 52
Autores: Bueno,Adeney de Freitas; Bueno,Regiane Cristina Oliveira de Freitas; Nabity,Paul David; Higley,Leon George; Fernandes,Odair Aparecido.
The twospotted spider mite Tetranychus urticae Koch is a common pest on soybean plants. To clarify plant-arthropod interaction on mite-soybean system, leaf fluorescence, photosynthetic responses to variable carbon dioxide levels, and chlorophyll content were evaluated. Significant photosynthetic rate reduction was observed due to stomatal limitation. Stomatal closure was the major plant physiological response. As a consequence, there was reduction in photosynthetic rates. Surprisingly, plants did not show chlorophyll content reduction associated with photosynthetic impairment. No differences in fluorescence data indicate that T. urticae injury did not impair the function of light harvesting and photoelectron transport. These results showed that T. urticae...

Provedor de dados: 52
Autores: Pratissoli,Dirceu; Oliveira,Harley Nonato de; Polanczyk,Ricardo Antonio; Holtz,Anderson Mathias; Bueno,Regiane Cristina Oliveira de Freitas; Bueno,Adeney de Freitas; Gonçalvez,José Roberto.
This work was carried out to study the effects of adult feeding and mating on the biological potential and parasitism of Trichogramma pretiosum and T. acacioi (Hymenoptera: Trichogrammatidae) to improve their use in biological control programs. Both species presented higher parasitism and longevity whenever adults were fed. Fed and unmated T. pretiosum females led to low parasitism whereas T. acacioi females did not present parasitism whatsoever. Egg viability of T. pretiosum was similar for fed and mated individuals, but T acacioi showed lower values for this parameter when unfed and without mating. Unmated females produced only males while mated ones had more than 60% female descendents for both Trichogramma species. Therefore, mated and fed female...

Different timing of whitefly control and soybean yield
Provedor de dados: 65
Autores: Vieira,Simone Silva; Bueno,Regiane Cristina Oliveira de Freitas; Bueno,Adeney de Freitas; Boff,Mari Inês Carissimi; Gobbi,Alysson Luis.
Trials were carried out in Paraúna, Goiás, Brazil, to evaluate the impact of whitefly on soybean yield. The experimental design was a randomized block, with four treatments and four replications (10m x 20m). The treatments were different levels of infestation, managed by applying insecticide at different timing; the control was kept free of insects by weekly insecticide spraying. The number of insects per leaflet was evaluated weekly, and at harvest the yield (kg ha-1) and the weight of 100 seeds (g) were recorded. The soybean was tolerant to whitefly, since only the treatment where nymphs per leaflet reached 136.31±26.60 (treatment without the use of insecticides) was sufficiently severe to cause yield loss. This loss was likely associated with the sooty...

Serpentine leafminer (Liriomyza trifolii) on potato (Solanum tuberosum): field observations and plant photosynthetic responses to injury
Provedor de dados: 65
Autores: Bueno,Adeney de Freitas; Zechmann,Benjamin; Hoback,William Wyatt; Bueno,Regiane Cristina Oliveira de Freitas; Fernandes,Odair Aparecido.
Serpentine leafminers, Liriomyza spp. (Diptera: Agromyzidae), are polyphagous insects that feed on numerous crops worldwide including potato. Recently, leafminer larvae (Liriomyza trifolii) have become an economically important pest of potato. The larvae eat the mesophyll of leaflets leaving long winding tunnels inside the leaflets. The photosynthetic effects of larval tunneling on the remaining leaf tissue are unknown. In 2003, physiological responses of potato to leafminer, L. trifolii were evaluated in Kearney, Nebraska, USA. The leaflets were examined 7 and 14 days post infestation for leaf area injury, photosynthetic rates and fluorescence. Leafminers caused up to 13% leaf area loss due to leafminer injury with no effect on the photosynthetic rates of...

A preservação dos agentes de controle biológico no agroecossistema é indispensável para o sucesso do manejo integrado de pragas. Entretanto, o controle químico de pragas ainda é indispensável em diversas culturas. Nesse contexto, a seletividade dos agrotóxicos aos inimigos naturais deve ser sempre considerada na escolha do melhor produto. Portanto, este estudo verificou o impacto causado por diferentes agrotóxicos na emergência do parasitoide de ovos Telenomus remus Nixon (Hymenoptera: Scelionidae), quando aplicados nas fases de larva e pupa (posturas de 100 a 150 ovos de Spodoptera frugiperda (J.E.

Telenomus remus releasing numbers may vary depending on the crop, plant architecture and/or the plant phenological stage. Thus, we examined the number of parasitoids needed for effective pest control of Spodoptera frugiperda on corn, cotton and soybean. In all crops, the parasitism response in relation to increasing numbers of the parasitoids had a quadratic effect. In corn, the maximum parasitism observed was 99.8% and 96.8% at a parasitoid releasing number of 0.231 and 0.264 T. remus females per S. frugiperda egg at phenological stages V4 and V10, respectively. Differently, in cotton and soybean, the highest parasitim were recorded using the highest tested T. remus releasing numbers (0.297 parasitoid per S. frugiperda egg). In cotton, it was 77.8% and...
