Entomofaunae in agroecosystem and its surroundings were compared, mainly focusing on natural enemy, between Laos and Vietnam, where organic and conventional farming are conducted, respectively. Great differences are recognized between them. Especially, many new and newly recorded species including potential natural enemy were discovered from northern Laos even in agroecosystem, such predators or parasitoids as Reduviidae and Lygaeidae(Heteroptera), Thripidae(Thysanoptera), Malachiidae(Coleoptera), and Ichneumonidae and Dryinidae(Hymenoptera). It is also noteworthy that a number of weevils, which are potentially useful for natural enemy of weeds, but are threatened with extinction by influence of insecticide in many areas, were frequently found in northern Laos.

比较了老挝和越南两种农业生态系统昆虫类群及其周围环境，主要以天敌为重点。人们认识到他们之间存在巨大差异。特别是在老挝北部的农业生态系统中，发现了包括潜在天敌在内的许多新种和新记录种，如寄生蜂科和蛱蝶科（异翅目）、飞蛾科（翅翅目）、孔雀科（鞘翅目）、姬蜂科和干蜂科（膜翅目）等捕食者或寄生性昆虫。还值得注意的是，在老挝北部经常发现一些象鼻虫，这些象鼻虫可能是杂草的天敌，但在许多地区由于杀虫剂的影响而有灭绝的危险。
