Abstract

Coffee berry borer (CBB) Hypothenemus hampei is a major biotic threat to coffee production worldwide. Studies have reported negative effects on CBB by oil-based formulations of neem (Azadirachta indica), but little information is available for other neem-extract formulations. This study evaluated CBB preference and performance in arabica coffee fruits and artificial diet treated with a neem-extract formulation (Openeem Plus®) in the field and laboratory conditions. Field experiments were performed using CBB females artificially infested in cherry or green coffee fruits confined in voile-fabric cages tied to branches of neem-treated and control plants, recording the adult mortality and offspring production. Dual-choice and no-choice bioassays assessed CBB preference and development in fruits and artificial diet treated with the neem extract compared to controls in the laboratory, respectively. As main results obtained in the field and laboratory experiments, the neem extract significantly reduced CBB oviposition in both cherry and green fruits, as well as in artificial diet compared to controls. However, the botanical product did not affect CBB adult survival and preference in the laboratory bioassays. The neem extract is promising for use in pest management strategies in sustainable arabica coffee crops by reducing CBB oviposition and offspring. These effects can contribute to lowering the pest population buildup along the crop cycle and damage potential to coffee production.

楝树提取物配方在阿拉伯咖啡果和人工饲料中对仓鼠喜好和表现的影响
咖啡浆果螟(CBB)Hypothenemus hampei 是全球咖啡生产的主要生物威胁。有研究报告称印楝(Azadirachta indica)油基制剂对 CBB 有负面影响,但关于其他印楝提取物制剂的信息却很少。本研究评估了在田间和实验室条件下,CBB 对阿拉比卡咖啡果实和用印楝提取物制剂(Openeem Plus®)处理过的人工食物的偏好和表现。在田间试验中,雌性 CBB 被人工感染在樱桃或绿色咖啡果实中,被关在绑在印楝萃取物处理过的植物和对照植物枝条上的薄纱笼中,记录成虫死亡率和后代产量。双重选择和无选择生物测定分别评估了 CBB 在经印楝提取物处理的水果和人工食物中的偏好和发育情况,并与实验室中的对照组进行了比较。田间和实验室实验的主要结果表明,与对照组相比,印楝提取物能显著减少 CBB 在樱桃和绿色水果以及人工饲料中的产卵量。然而,在实验室生物测定中,该植物产品并不影响 CBB 成虫的存活率和偏好性。楝树提取物可减少 CBB 的产卵和后代,因此有望用于可持续阿拉伯咖啡作物的害虫管理策略中。这些作用有助于降低害虫在作物周期中的种群数量和对咖啡生产的潜在危害。
