Abstract

Adults of Cephalonomia stephanoderis Betrem were detected (in November 2003) during the sampling of Coffea canephora Pierre ex A. Froehner berries damaged by Hypothenemus hampei Ferrari (Coleoptera: Scolytidae) in Ouro Preto D'Oeste - Rondônia, Brazil (10 degrees 45'S and 62 degrees 15'W). From January to July 2004, the parasitoid was monthly sampled in 200 berries damaged by H. hampei. Probably, C. stephanoderis can already exert some parasitism pressure at the coffee berry borer population. The occurrence of this parasitoid in natural conditions points out to another alternative for the biological control of the H. hampei in Rondônia. This is the first record of C. stephanoderis in coffee plantations of the Brazilian Amazonia.

摘要

2003年11月，在巴西朗多尼亚州奥鲁普雷图-多埃斯特（南纬10度45分，西经62度15分）对遭受咖啡果小蠹（Hypothenemus hampei Ferrari，鞘翅目：小蠹科）为害的卡内弗拉咖啡（Coffea canephora Pierre ex A. Froehner）浆果进行采样时，检测到了斯蒂芬氏头孔小蠹（Cephalonomia stephanoderis Betrem）的成虫。2004年1月至7月，每月在200个被咖啡果小蠹为害的浆果中对该寄生蜂进行采样。斯蒂芬氏头孔小蠹可能已经对咖啡果小蠹种群施加了一定的寄生压力。这种寄生蜂在自然条件下的出现，为朗多尼亚州咖啡果小蠹的生物防治指出了另一种选择。这是斯蒂芬氏头孔小蠹在巴西亚马孙地区咖啡种植园的首次记录。
