| Research Abstract |
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.
