摘要: Abundance and diversity of pest predator species at different stages crop growth were studied in chemical insecticidetreated untreated irrigated rice production systems the Philippines a single season. Immigration to fields from adjoining vegetated patches was also monitored for assessing potential role latter group natural biological control. Dominant during tillering stage plant leafhoppers belonging Hemipteran families Cicadellidae Delphacidae. Higher recorded milk both treatments compared other pheno-phases. Among species, Micraspis crocea, Conocephalus longipennis, Metioche vittaticollis, Agriocnemis spp., Cyrtorhinus lividipennis abundant. Malaise trap catches indicated movement pests, namely Recilia dorsalis, Cofona spectra, Nephotettix Nilaparvata lugen s, Eysarcoris spp. such as M. vittaticollis areas. Diversity richness indices predators higher insecticide-treated fields. Highest found stage, while highest stage. Implicit this is that increased, followed.
