The previously identified female sex pheromone of cocoa pod borer (CPB), (Snellen) (Lepidoptera: Gracillariidae), was re-evaluated for male attraction using six different pheromone formulations in Indonesian cocoa plantations. In a dose-response experiment, the 0.1 mg pheromone load was significantly more attractive to male CPB than the lower doses tested. Additionally, during the first four-week trapping period, USDA (Beltsville, MD, USA) lures containing 0.1 mg of synthetic pheromone blend exhibited significantly better attraction than the commercial lure obtained from Alpha Scents, Inc. (Canby, OR, USA) with the same pheromone load (0.1 mg). Although the 1.0 mg lure did not show any higher attraction than the 0.1 mg lure during the first month, it was significantly attractive for CPB males with the same weekly average capture efficacy for the whole twenty-seven weeks in field conditions in 2018. A long-life pheromone lure can be particularly useful in monitoring large-scale cocoa farms.
利用六种不同的性信息素配方，在印度尼西亚的可可种植园中，对之前鉴定出的可可果蛀蛾（Conopomorpha cramerella （Snellen），鳞翅目：细蛾科）雌虫性信息素吸引雄虫的效果进行了重新评估｡在剂量反应实验中，0.1毫克的性信息素负载对可可果蛀蛾雄虫的吸引力显著高于所测试的较低剂量｡此外，在最初四周的诱捕期内，含有0.1毫克合成性信息素混合物的美国农业部（美国马里兰州贝尔茨维尔）诱芯，其吸引力显著优于来自美国俄勒冈州坎比市阿尔法气味公司、具有相同性信息素负载（0.1毫克）的商业诱芯｡虽然在第一个月，1.0毫克的诱芯没有表现出比0.1毫克的诱芯更高的吸引力，但在2018年的田间条件下，在整个27周内，它对可可果蛀蛾雄虫具有显著吸引力，且每周平均捕获效率相同｡长效性信息素诱芯在监测大规模可可农场方面可能特别有用｡
