Abstract

Coffee berry borer, Hypothenemus hampei (Ferrari, 1867), is a serious insect pest of organic coffee plantation in São Tomé Island. To date, limited information regarding the seasonal phenology of this pest species on the islands limits the implementation of integrated pest management (IPM) programmes. As part of a coffee farmer training programme, three attractants were evaluated in red vs. transparent traps to assess olfactory and visual stimuli. The experiment was delineated in a split-block design with three types of attractants: commercial ethanol + 40 g of ripe Robusta coffee (A1), proportion 3:1 methanol and ethanol (A2), and commercial ethanol + 10 g of ground roasted Arabica coffee (A3); and two home-made transparent (D1) and red (D2) traps. The results showed that there was significant interaction between the trap model and the attractant for borer capture. The transparent trap baited with methanol and ethanol exhibited the best result with an average of 14.3 ± 5.4 adults/trap/week. Transparent traps baited captured more borers and largest numbers of beetles were trapped late May through September. In short, home-made traps alone are not effective for controlling the coffee berry borer, but they are useful in monitoring this species.

不同诱捕器和诱饵对咖啡浆果蛀虫的效果，São Tomé岛的Hypothenemus hampei（法拉利，1867）

咖啡浆果蛀虫(Hypothenemus hampei, Ferrari, 1867)是 o tom岛有机咖啡种植园的一种严重害虫。迄今为止，关于这些岛屿上这种有害生物的季节性物候的资料有限，限制了有害生物综合管理方案的实施。作为咖啡农培训计划的一部分，在红色陷阱和透明陷阱中评估了三种引诱剂，以评估嗅觉和视觉刺激。实验采用三种引诱剂:商业乙醇+ 40 g成熟罗布斯塔咖啡(A1)，甲醇和乙醇的比例为3:1 (A2)，商业乙醇+ 10 g磨碎的烘焙阿拉比卡咖啡(A3);以及两个自制透明(D1)和红色(D2)捕集器。结果表明，诱虫器模型与诱虫剂之间存在显著的交互作用。以甲醇和乙醇为饵的透明捕集器捕集效果最好，平均捕集14.3±5.4只/周。透明的陷阱诱捕了更多的蛀虫和最多的甲虫，在5月下旬到9月被诱捕。简而言之，仅靠自制的捕虫器对控制咖啡浆果蛀虫是无效的，但它们对监测该物种是有用的。

期刊介绍： African Entomology (ISSN 1021-3589 – print / 2224-8854 – online) replaced the old Journal of the Entomological Society of Southern Africa in 1993. A single volume consisting of two issues (March and September) is published annually. The journal is indexed in all major abstracting journals African Entomology is a peer reviewed scientific journal that publishes original research articles and short communications on all aspects of entomology, with an emphasis on the advancement of entomology on the African continent.
