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 different pesticides on the control of main citrus pests and citrus orchards insect communities were compared. Three different combinations of inorganic pesticides, selective pesticides and broad-spectrum pesticides have different effects on the composition, abundance, diversity, evenness and total population of the four communities in citrus orchard. Selective pesticides and inorganic pesticides group, the community not only maintained a certain degree of richness and diversity, but also reduced the population of pests dominant population. The distribution area of broad-spectrum pesticides, community richness, diversity lowest, and the dominant species is very prominent.
