Abstract


Summary

We report on the foraging behavior of Polybia scutellaris (White) (Hymenoptera: Vespidae) and the damage it causes to the fruit of Syzygium jambos (L.) Alston (Myrtaceae). Of 32 wasps monitored, 26 visited fruit on the ground and 6 visited fruit on the branches. Foraging was most frequent in late morning and early afternoon.

 

Sumário

Polybia scutellaris (Write) (Hymenoptera: Vespidae) preda insetos pragas, porém pode danificar cascas de frutos de Syzygium jambos (L.) Alston (Myrtaceae), tornando-os comercialmente inviáveis. Trinta e dois indivíduos dessa vespa foram observados, 26 visitando frutos amadurecidos no solo e seis naqueles fixos nos galhos. O forrageio de P. scutellaris foi mais frequente no final da manhã e início da tarde.
