Uma alternativa ao uso de produtos químicos para o controle de artrópodes fitófagos em ambientes agrícolas é a utilização de agentes de controle biológico. O objetivo deste estudo foi avaliar o desenvolvimento de Chrysoperla externa (Hagen, 1861) (Neuroptera, Chrysopidae) alimentado com ovos, ninfas e adultos da mosca-branca-do-cajueiro, Aleurodicus cocois (Curtis, 1846) (Hemiptera: Aleyrodidae) e ovos da traça-da-farinha, Anagasta kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae). Diariamente, larvas recémeclodidas de C. externa foram alimentadas ad libitum com as presas fornecidas

Chrysoperla externa (Neuroptera: Chrysopidae) and Utetheisa ornatrix (Lepidoptera: Arctiidae) on organically grown Crotalaria juncea (Fabaceae)
Provedor de dados: 87
Autores: Costa,M.A.; Tavares,W.S.; Pereira,A.I.A.; Cruz,I.; Serrão,J.E.; Zanuncio,J.C.
Chrysoperla externa (Neuroptera: Chrysopidae) larvae can avoid foraging on plants of Crotalaria juncea (Fabaceae) after the issuance of floral buds, when the prey of Utetheisa ornatrix (Lepidoptera: Arctiidae) incorporate toxic pyrrolizidine alkaloids from this plant. This reduces the predation and favors increasing the number of adults and eggs of this defoliator on crops of this plant. The aim of the present paper was to evaluate some biological and ecological aspects of C. externa and U. ornatrix on the organic crop of C. juncea in the EMBRAPA Maize and Sorghum in Sete Lagoas, Minas Gerais State, Brazil. Chrysoperla externa and U. ornatrix were more abundant in the vegetative and flowering stages of C. juncea, respectively, with caterpillars of this...

Searching and handling time of Chrysoperla externa (Hagen, 1861) (Neuroptera, Chrysopidae) larvae fed on Uroleucon ambrosiae (Thomas, 1878) (Hemiptera, Aphididae). The objective of this research was to determine the searching and handling times of three larval instars of C. externa fed on U. ambrosiae at densities of 30, 40 and 50 per vial, with the feeding of the larvae at the preceding instars being U. ambrosiae nymphs or Sitotroga cerealella (Olivier, 1819) eggs. The larvae were maintained at 25 ± 2 ºC, 70 ± 10% RH and a 14-h photophase. A completely randomized design in a 6 x 3 factorial scheme with 12 replicates was adopted. The shortest searching time was found for the 2nd and 3rd instar larvae of C. externa, and this parameter was variable depending...

Can larval lacewings Chrysoperla externa (Hagen): (Neuroptera, Chrysopidae) be reared on pollen?
Provedor de dados: 92
Autores: Oliveira,Simone Alves de; Souza,Brígida; Auad,Alexander Machado; Carvalho,Caio Antunes.
The aim of this study was to verify the viability of exclusive use of elephant grass pollen, Pennisetum purpureum (Schum), to feed larvae of the lacewing Chrysoperla externa (Hagen, 1861). The insects were kept at 24ºC and the duration and survival rate of each instar and the larval and pupal phases were recorded. The diet provided complete development of the larvae. The average duration of the first and second instars was the same (6.9 days), while the third instar lasted an average of 10.0 days and the pupal phase 13.2 days. The average survival of the larvae was above 80% for the first, second and third instars, and 70.0% and 33.3% for the larval and pupal phase, respectively. These results indicate that the exclusive use of elephant grass pollen can...

Feeding potential of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) in different densities of Uroleucon ambrosiae (Thomas) (Hemiptera, Aphididae). The feeding potential of 2nd and 3rd instar larvae of Chrysoperla externa (Hagen, 1861) in relation to different densities of 30, 40 and 50 nymphs of Uroleucon ambrosiae (Thomas, 1878) at 3rd and 4th instars was evaluated. The treatments were individualized into 2.5 cm in diameter and 8.5 cm tall flat bottom glass vials and maintained in a controlled environmental chamber at 25±2 ºC temperature, 70±10% RH and 14 h photophase. A completely randomized experimental design with 10 replications was used. The consumption of the prey nymphs by the predator larvae was evaluated after 1, 2, 4, 8, 16 and 24 h from...

Polimorfismo no padrão de manchas tegumentares de larvas e adultos de Ceraeochrysa caligata (Neuroptera: Chrysopidae) e redescrição dos instares larvais
Provedor de dados: 103
Autores: Viana,Gustavo G.; Albuquerque,Gilberto S.
Ceraeochrysa caligata (Banks, 1945) is one of the several species of Ceraeochrysa Adams, 1982 that occur in agroecosystems of the Neotropical region and show potential for use in biological control programs. However, little is known about its biology, partly because of the poor status of the systematics of this group. To help in the identification of C. caligata and to contribute with additional characters for future phylogenetic studies with the genus, here we characterize the variations in relation to the pattern of integument markings originally described for the adults and larvae and redescribe the three larval instars, including characters not considered in the original description, especially the number of setae in the tubercles and somatic segments....

Biological aspects of the immature stages of Ceraeochrysa everes (Banks) (Neuroptera: Chrysopidae)
Provedor de dados: 63
Autores: Barbosa,Leonardo Rodrigues; Freitas,Sérgio de; Auad,Alexander Machado.
A knowledge of the behavior and biological aspects of natural enemies is extremely important for the establishment of biological control programs. Biological aspects of the larvae, pre-pupae and pupae of the predator Ceraeochrysa everes (Banks) were studied. Larvae of the adult F1 generation were reared in the laboratory (25 ± 2°C, 65 ± 10 % RH and 14h photophase) on eggs of the Angoumois grain moth Sitotroga cerealella (Olivier). The duration and viability of the embryonic period, development of the immature stages and egg-adult period were evaluated. The mean embryonic period was 5.0 days, while the mean durations of the first, second and third instars were: 5.1 ± 0.03; 4.3 ± 0.05 and 4.5 ± 0.05 days, respectively, with viability exceeding 90%. Duration...

Development and consumption capacity of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) fed with Cinara spp. (Hemiptera, Aphididae) under three temperatures
Provedor de dados: 104
Autores: Cardoso,Josiane T.; Lazzari,Sonia M. N.
The giant conifer aphids Cinara pinivora (Wilson, 1919) and Cinara atlantica (Wilson, 1919) (Hemiptera: Aphididae) are pests on Pinus spp. (Pinaceae) in the South and Southeast regions of Brazil. Larvae of Chrysoperla externa (Hagen, 1861) (Neuroptera, Chrysopidae) were observed feeding voraciously on these aphid colonies. In order to evaluate their potential as biological control agents, some biological parameters and their consumption capacity were studied in laboratory. Ten larvae were isolated in plastic vials and fed with aphids of small size (nymphs of 1st and 2nd instars) and 10 with aphids of medium size (nymphs of 3rd and 4th instars), maintained at 15ºC, 20ºC and 25ºC, under 12:12 h photoperiod and 70 ± 10% RH, and observed daily. The egg...

Reproductive potential of Chrysoperla externa maintained in different cage sizes in laboratory conditions
Provedor de dados: 65
Autores: Battel,Ana Paula Magalhães Borges; Moral,Rafael de Andrade; Rodrigues,Camila Alves; Araújo,Márcio da Silva; Godoy,Wesley Augusto Conde.
ABSTRACT: This study investigated the influence of cage sizes on the survival and reproductive potential of Chrysoperla externa (Hagen). Size of breeding cages significantly affected the reproductive potential of C. externa . Our results indicated that in cages smaller (7.5cm of diameter) than those usually recommended for the rearing of this insect (10cm diameter), females showed higher rates of oviposition. Reduction of space for rearing natural enemies in the laboratory is very important for developing biological control programs.
