摘要
比较了不同药剂组配对柑桔主要害虫的防治效果及对柑桔园昆虫群落的影响。无机农药、选择性农药及广谱性农药三种不同组配方式对柑桔园昆虫群落的组成及丰富度、多样性、均匀度、个体总数四个群落参数上差异较大。选择性农药及无机农药组配区，群落既维持了一定的丰富度、多样性，又减少了害虫优势种群的虫口数量。广谱性农药组配区，群落丰富度、多样性最低，且优势种十分突出。
The effects of inorganic, selective and broad-spectrum insecticide combinations, which were all effective in controlling the main insect pests of citrus such as the spider mites, scales, and moths, etc, on the insect community in citrus orchard were compared. There were significant differences among the four community parameters, namely, the richness, diversity, evenness and individual number of the three treatments. For the inorganic and selecive insecticide combination treatments, the higher richness and diversity were maintained in the insect communities, while the dominant incest pest populations were reduced. The orchard treated with broad spectrum insecticide contained fewest species and the individuals per species were most uneven, of which the dominant insect pests were very prominent.
