Protopolybia exigua (Hymenoptera: Vespidae) nesting on Citrus grandis (Rutaceae)
Social wasps are predators. Two nests of Protopolybia exigua (Saussure) (Hymenoptera: Vespidae) were collected on pomelo (Citrus grandis [L.]) (Rutaceae) leaves, 1 active and another abandoned. The colonies of P. exigua were located under pomelo leaves, providing protection against adverse environmental conditions. The active nest had 12 pedicels, 600 brood cells, and 15 adult wasps. The knowledge of nesting habits of wasps in agroecosystems favors the management of these insects for biological control.
Vespas sociais são predadores. Dois ninhos de Protopolybia exigua (Saussure, 1854) (Hymenoptera: Vespidae) foram coletados em folhas de grapefruit (Citrus grandis [L.]) (Rutaceae), um ativo e outro abandonado. As colônias de P. exigua estavam localizadas sob folhas de pomelo, proporcionando proteção contra condições ambientais adversas. O ninho ativo tinha 12 pedicelos, 600 células de cria e 15 vespas adultas. O conhecimento dos hábitos de nidificação de vespas em agroecossistemas favorece o manejo desses insetos para o controle biológico.
