Inventário Rápido de Vespas Sociais em Três Ambientes com Diferentes Vegetações

Apesar de essenciais, trabalhos que objetivem conhecer a riqueza de vespas em meios naturais e agricolas sao incipientes, refletindo em escassez de tempo, recursos e logistica adequada para a sua elaboracao. Assim, nosso estudo buscou conhecer as especies de vespas sociais em area com fragmento florestal, plantio de eucaliptos e pomar, alem de testar a hipotese de que inventarios rapidos, utilizando-se a busca ativa e armadilhas atrativas sao estrategias viaveis para amostrar especies com maior abundância. Foram coletadas 365 vespas sociais, distribuidas em quatro generos e 10 especies, de modo que o pomar registrou maior riqueza especifica (s=8), diversidade (H’=0,5131) e abundância (n=218). Tanto Agelaia vicina (Saussure), quanto Polybia ignobilis (Haliday) e Polistes versicolor (Oliver) foram relatadas nas tres areas. O genero Agelaia contabilizou mais de 70% dos individuos coletados, resultados equivalentes aos de trabalhos conduzidos em fitofisionomias similares, validando a hipotese apresentada. Os inventarios constituem-se, ferramentas eficazes na amostragem de especies de vespas sociais abundantes, refletindo na diminuicao de custos e logistica em trabalhos de levantamento, contribuindo com ampliacao do numero de estudos sobre conservacao e monitoramento ambiental, alem dos relacionados a programas de manejo integrado de pragas. A Fast Inventory of Social Wasps in Three Environments with Different Vegetation Abstract. Although essential, researches that seek to discover the richness of wasps in natural and agricultural environments are incipient, reflecting in shortage of time, resources and adequate logistics for its formulation. Therefore, our study sought to know the species of social wasps in areas with forest fragments, eucalyptus plantations and orchard, in addition to test the hypothesis that fast inventories involving active search and attractive traps are viable strategies for sampling species with greater abundance. We collected 365 social wasps, distributed amongst four genera and 10 species, and the orchard reported the greatest specific richness (s=8), diversity (H'=0.5131) and abundance (n=218). Agelaia vicina (Saussure), Polybia ignobilis (Haliday) and Polistes versicolor (Oliver) were found in the three areas. The genus Agelaia accounted over 70% of the collected individuals, results equivalent to those carried out in similar works regarding phytophysiognomy, thus validating the presented hypothesis. The inventories are effective tools on sampling abundant social wasps species, reflecting on the decrease of costs and logistics in diversity studies, contributing with an increase of the number of conservation and environmental monitoring research, in addition to the ones related to integrated pest management programs.
