Occurrence of Social Wasps (Hymenoptera: Vespidae) in a Sugarcane Culture

Predation of Lepidoptera caterpillars - including agricultural pest species - is one of the main ways through which social wasps gather proteinaceous resources. The presence of social wasps was sampled through active search and bait traps through a sugarcane culture cycle, totaling 12 months. Our aim was to record the presence of these insects during the sugarcane development cycle in order to obtain data to support alternative pest control strategies. A total of 1091 individuals in seven genera and 20 species of social wasps were collected, including the swarm-founding Agelaia vicina and Polybia sericea (Hymenoptera: Vespidae). Social wasp richness and abundance were not correlated with climatic variables (temperature, humidity and precipitation). However, richness was negatively correlated to the sugarcane plants’ height (r= -0.4360, p= 0.05). The presence of social wasps during the plant’s cycle shows their potential as predators in sugarcane culture pest management.
