摘要

The occurrence and damage of Xylotrechus quadripes Chevr were investigated in different time points and micro environments in Simao south island river coffee test demonstration field. The results showed that X. quadripes mainly damaged 5-year-old coffee trees. X. quadripes occurred one generation per year in Simao region,and the larval stage lasted 296-322 d. The adult could be found in four seasons because of different development progress and overlapping generations. In different micro environments,X. quadripes were mainly distributed in mixed forests and the coffee land in sunny slope. The adult enjoyed sunshine on the coffee trees at noon. The natural enemy Prislauacus nigripea kieff was found to parasitize in the larvae of X. quadripes,which could control the population of X. quadripes.
