摘　　要：采用田间调查法研究了槟榔间种胡椒后对槟榔害虫及天敌资源的影响。结果表明,间种胡椒后槟榔园害虫数量呈现减少的趋势,而与此相对应的害虫天敌数量呈现上升的趋势。以8月31日调查结果为例,红脉穗螟、椰心叶甲、蛞蝓、基斑毒蛾、椰花四星象甲总数减少了28.13%,天敌数量增加了35.14%。在槟榔园进行胡椒的间种可降低槟榔害虫的虫口数量,减轻槟榔植株受害程度。A survey was conducted to study the effect of intercropping pepper in areca fields on the number of major insect pests and predator species. The results showed that upon intercropping pepper plants in betel nut plantation fields, the numbers of insect pests trended to decrease, ＂while the numbers of their predators tended to increase. For example, based on the field survey on August 31, there was a 28.13% reduction on the total number of Tirathaba rufivena Walker, Brontispa longissima Gestro, Agriolimax agrestis Linnaeus, Dasychira mendosa Hubner, Diocalandra frumenti Fabricius, while there was a 35.14% increase on the number of predator species （wasps, ladybugs, spiders and Chelisoches morio Fabricius）. Therefore, intercropping pepper in areca plantation can reduce the number of insect pests and thereby the extent of insect damage to the areca crop.
