The coffee berry borer (CBB), Hypothenemus hampei Ferrari (Coleoptera: Curculionidae), is the most important coffee pest in most of the coffee growing countries. CBB females leave old dry berries after harvest and search for dry noninfested berries on the plant or on the ground to lay eggs or to use as refuge until new berries are available on the coffee trees in the following season. The CBB infestation level and emergence from berries on the ground or on the plants were evaluated in two fields post-harvest in the Spring in Brazil over two seasons. Twenty infested or noninfested berries in separate cages (250 ml plastic cups) were placed on the plants or on the ground under the tree canopy, in each field. The number of infested berries and CBB females that emerged from the infested berries were recorded weekly. CBB emergence was higher from berries on the ground than those on the coffee trees in both seasons, whereas CBB infestation was higher on coffee berries on the plants than those on the ground in season I. Insolation (hours of sunlight) and temperature were the main covariates that affected emergence and infestation by this insect. The results are discussed for monitoring CBB during the time of dispersal with implications on integrated management of this pest.
咖啡果蛀虫（CBB），Hypothenemus hampei Ferrari（鞘翅目：象甲科），是大多数咖啡种植国家最重要的咖啡害虫。CBB 雌性在收获后会离开旧的干燥浆果，并在植株上或地面上寻找干燥未受感染的浆果产卵或作为避难所，直到下一季咖啡树上有新的浆果。在巴西的两个春季收获后，在两个季节的两个田间评估了 CBB 的感染水平和从地面或植物上的浆果中出现的情况。在每个田间，将 20 个受感染或未受感染的浆果分别放在单独的笼子（250 毫升塑料杯中）中，放在植株上或树冠下的地面上。每周记录受感染浆果中出现的受感染浆果数量和 CBB 雌性数量。在两个季节中，CBB 从地面上的浆果中出现的数量均高于从咖啡树上的浆果中出现的数量，而在第一季中，CBB 在植株上的咖啡浆果上的感染率高于地面上的浆果。太阳辐射（日照小时数）和温度是影响这种昆虫出现和感染的主要协变量。讨论了这些结果，以用于监测 CBB 在扩散期间的情况，并对该害虫的综合管理产生影响。
