| 实物特征: | The size of a population and its variations through time and space are important variables that can be used to detennine insect community structure in ¡he field. For this reason ethanolic traps were used to study population fluctuation of Scolytidae species in plantations of Eucalyptus grandis. This study was developed during two years in António Dias, State of Minas Gerais, Brazil where these insects were collected and analyzed in function of temperature and rainfall. Out of 16 Scolytidae species collected those with higher number of individuals were Xyleborus paraguayensis, Xyleborus affinis and Xyleborus jerrugineus (96.27 % of individuals). Temperature and rainfall affected numbers of these insects collected with ethanolic traps. The first two species presented larger populations during periods of low rainfall while X.jerrugineus presented the opposite pattem. |
