[目的]咖啡豆象是世界性仓储害虫,主要分布于热带亚热带地区,与重要能源植物麻疯树的生态区重叠,有必要调查其对麻疯树的危害性。[方法]以贵州罗甸种植区为调查点,对野外麻疯树林分及室内果实储藏物进行调查,掌握害虫发生情况及其为害后果,并对其分类地位进行确定。[结果]咖啡豆象在罗甸麻疯树种植区普遍分布,室内及林间均见其发生为害;成虫取食真菌,对麻疯树果实的直接为害性很小,但成虫将卵产于果皮内,幼虫在其中孵化并取食,最终可将果皮蛀空,从而对果实造成直接为害;另外,咖啡豆象还可能具有一系列的潜在危害性包括直接蛀食种子、传播病原物、威胁产区其他经济作物等。[结论]麻疯树是咖啡豆象的新寄主,咖啡豆象对其有一定的危害性,对其产品、其他经济作物有一定的潜在危害性,应加强对咖啡豆象的研究和防控力度。
[Objective] The coffee bean is a worldwide storage pest mainly distributed in the tropical and subtropical regions. It overlaps with the ecologic area of Jatropha curcas, an important energy plant, and it is necessary to investigate its harmfulness to Jatropha curcas. [Method] With the investigation of Luodian planting area in Guizhou as an investigation point, the investigation was made on the storage of jatropha curcas and indoor fruits in the wild to monitor the pest occurrence and the consequences of the damage, and the classification status was determined. [Result] The coffee beans were widely distributed in Jatropha curcas plantation area, and were found to be harmful to both indoor and forest. The adults fed on the fungus had little direct damage to the fruit of Jatropha curcas, but the adults produced eggs in In the pericarp, the larvae hatch and feed on them, which can eventually erode the pericarp, thus causing direct damage to the fruit. In addition, the coffee beans may also have a series of potential dangers including directly eliciting seeds, transmitting pathogens, threatening Other cash crops in the producing area [Conclusion] Jatropha curcas was the new host of coffee bean, and the coffee bean had certain harmfulness to it, which had certain potential harm to its products and other cash crops. The research and prevention and control of coffee bean should be strengthened Strength.
