Abstract

The aim of this study was to identify predatory insects and arachnids of pest insects, associated with avocado and tangerine crops. With this objective, 48 farms located in the Valley of Cañete were visited. About 180 representative ha with crops were randomly selected (100 ha with tangerine and 80 ha with avocado), in which a total of 2000 tangerine trees and 1600 avocado trees were checked. The specimens were collected with an entomological net and deposited in glass vials with 70% ethanol; in addition to being placed in plastic bags, for subsequent montage and identification in the laboratory. The results reflected the presence of eight orders, 17 families and 23 species of predators, from which Ceraeochrysa cincta (Schneider, 1851) (Neuroptera: Chrysopidae) stands out, as a predator of Aphis spiraecola (Hemiptera: Aphididae); Harmonia axyridis Pallas, 1773 (Coleoptera: Coccinellidae), as a predator of immature forms of Hemiptera and a species of spider, Gasteracantha cancriformis L., 1758, (Araneae: Araneidae), as a generalist predator. The limited number of specimens collected reflects the pressure of pesticides on conventionally managed crops, therefore, for a better use of the ecosystem services provided by predatory taxa, awareness should be created in the rational use of these products and a more efficient management, responsible and respectful with the productive agroecosystem.
