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.

巴西收获后咖啡浆果在植物上或地面上的出现和侵染水平

咖啡浆果蛀虫（CBB），Hypothenemus hampei Ferrari（鞘翅目：Curculionidae）是大多数咖啡种植国最重要的咖啡害虫。CBB 雌性在收获后留下旧的干燥浆果，并在植物或地面上寻找干燥的未受感染的浆果产卵或用作避难所，直到下一季的咖啡树上出现新的浆果。在巴西春季收获后的两个田地中，在两个季节内评估了 CBB 侵染水平和地面或植物上浆果的出现情况。将 20 个单独的笼子（250 ml 塑料杯）中的受侵染或未受侵染的浆果放在植物上或树冠下的地面上，在每个田地中。每周记录受侵染浆果的数量和从受侵染浆果中出现的 CBB 雌性。两个季节，地面浆果的 CBB 出现率均高于咖啡树上的 CBB，而第一季植物上咖啡浆果的 CBB 侵染率高于地面。日照（日照时间）和温度是主要的影响这种昆虫的出现和侵染的协变量。讨论了在传播期间监测 CBB 的结果，并对这种有害生物的综合管理产生了影响。
