Resumo: The ring-legged earwig Euborellia annulipes has been studied as a natural enemy of pest-insects and a potential predator of diamondback moth. Temperature is an important factor that mediates the pest population density and may affect the predator-prey relationship dynamics. This study aimed to evaluate the effect of the temperature and development stage of Plutella xylostella individuals on the feeding preference of E. annulipes females. Three temperatures (18 ºC, 25 ºC and 32 ºC), two development stages (larvae and pupae) and two feeding conditions related to the prey capture (with or without choice) were assessed. No matter the temperature, ring-legged earwig females showed a preference for eating larvae, instead of pupae. The temperature and choice conditions influenced the amount of consumed preys, but only for larvae (not for pupae). The lowest larvae consumption was observed at 18 ºC, in both prey capture conditions. KEYWORDS: Biological control, brassicas, earwig, integrated pest management, thermal conditions.

A temperatura é um fator importante para mediar o aumento da densidade populacional de pragas, podendo afetar as dinâmicas da relação predador-presa. Objetivou-se avaliar o efeito da temperatura e do estágio de desenvolvimento de indivíduos de Plutella xylostella na preferência alimentar de fêmeas de E. annulipes. Três temperaturas (18 ºC, 25 ºC e 32 ºC), dois estágios de desenvolvimento (lagartas e pupas) e duas condições de alimentação relacionadas à captura das presas (com e sem escolha) foram avaliados. Independentemente da temperatura, fêmeas de tesourinha mostraram preferência alimentar por lagartas, ao invés de pupas. As condições de temperatura e de escolha influenciaram na quantidade de presas consumidas, mas apenas para larvas (não para pupas). O menor consumo de lagartas foi observado sob 18 ºC, em ambas as condições de captura.
