Abstract

A presente pesquisa objetivou avaliar os efeitos da taxa de crescimento de ramos na abundância dos insetos herbívoros de vida livre associados a Caryocar brasiliense em três diferentes "habitats" (cerrado, mata seca e pastagem). Em cada "habitat" foram escolhidas 20 árvores e em cada uma, marcados quatro ramos, que foram monitorados mensalmente de junho a novembro de 2001. Durante esse monitoramento foi encontrado um total de 47 morfoespécies de insetos (quatro ordens), associados aos ramos de C. brasiliense. A taxa de crescimento dos ramos foi significativamente diferente entre os "habitats" estudados. Contudo, apenas no cerrado se observou relação significativa entre a abundância de herbívoros e a taxa de crescimento dos ramos.<br>The present research aimed at evaluating the effects of branch growth rate in the abundance of free life herbivore insects associated with Caryocar brasiliense in three different habitats (savannah, dry forest, and pasture). In each habitat 20 trees were chosen and in each tree four branches were marked,they were monitored monthly from June to November of 2001. During the monitoring, 47 morphoespecies (four orders) were found associated with branches of C. brasiliense. Branch growth rate was significant by different, among the studied habitats. However, just in the savannah a significant relationship among the abundance of herbivores and branch growth rate was observe
