Resposta funcional de Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) alimentada com Schizaphis graminum (Rondani) (Hemiptera: Aphididae)

Abstract: An. Soc. Entomol. Brasil 29(2): 309-317 (2000) Functional Response of Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae)Fed on Schizaphis graminum (Rondani) (Hemiptera: Aphididae)ABSTRACT -The functional response of Chrysoperla externa (Hagen) fed on Schizaphis graminum (Rondani) was studied under five densities of prey. The experimental design was completely randomized with five treatments and ten replications. The tests were conducted in growth chambers at 25 ± 1ºC, RH of 70 ± 10% and photophase of 12 … Show more

“…The total larval period found for C. externa at 25ºC (10.9 days) showed a similar pattern observed when this species was fed with the greenbug, Schizaphis graminum (Rondani, 1852) (Hemiptera, Aphididae), it took 10.8 to 12 days to complete its larval development (FONSECA et al 2000). It was also observed by VENZON & CARVALHO (1993) for the green lacewing Ceraeochrysa cubana (Hagen, 1861) (Neuroptera, Chrysopidae) that the larval development time decreases with temperature elevation.…”

“…CANARD & PRINCIPI (1984) mention that chrysopids in general, consume 80% of the total food intake during the third instar, increasing the consumption with the decrease of temperature. That tendency was also confirmed by FONSECA et al (2000) for this same species fed with the greenbug S. graminum and by LIAO et al (1985) for the green lacewings C. quadrinpunctata and C. rufilabris fed with the aphid Monellia caryella (Fitch, 1855) (Hemiptera: Aphididae).…”

“…São insetos polífagos, com atuação importante na redução da densidade populacional de diversos artrópodes-praga. Na Região Neotropical, destaca-se Chrysoperla externa (Hagen), ocorrendo naturalmente em várias culturas de interesse econômico, como a do cafeeiro, e é considerada agente potencial de controle biológico de diversas pragas de importância agrícola (Gravena 1992, Carvalho et al 1994, Fonseca et al 2001.…”

“…Por outro lado, observou-se que a correlação entre os ínstares e o consumo foi significativa e positiva, caracterizando um aumento no número de ovos predados em função do desenvolvimento larval, o que já era esperado, uma vez que larvas em estádios mais avançados de desenvolvimento são capazes de capturar um maior número de presas em conseqüência dos menores tempos de busca e de manuseio, conforme constatado por Fonseca et al (2000). Médias seguidas pela mesma letra minúscula nas linhas e maiúscula nas colunas não diferem entre si pelo teste de Scott e Knott (P 0,05).…”
