Abstract

We report on the predatory consumption of prey by adult Chauliognathus flavipes (F.) (Coleoptera: Cantharidae), Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae), and Orius insidiosus (Say) (Hemiptera: Anthocoridae) in laboratory no-choice feeding tests. Chauliognathus flavipes more commonly preyed on eggs of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) and nymphs of Myzus persicae (Sulzer) (Hemiptera: Aphididae). Cycloneda sanguinea fed on more M. persicae nymphs while O. insidiosus fed slightly more on Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) and T. absoluta eggs compared with Thrips spp. nymphs.

 

Sumario

Nós reportamos a eficácia predatória das presas dos adultos de Chauliognathus flavipes (F.) (Coleoptera: Cantharidae), Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae) e Orius insidiosus (Say) (Hemiptera: Anthocoridae) alimentados com diferentes presas. A predação de C. flavipes foi maior em ovos de Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) e ninfas de Myzus persicae (Sulzer) (Hemiptera: Aphididae). Cycloneda sanguinea alimentou-se mais de ninfas de M. persicae enquanto O. insidiosus alimentou um pouco mais com ovos de Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) e T. absoluta em comparação com ninfas de Thrips spp.
