摘　　要：为了明确梨园生草对梨园主要害虫梨木虱和梨黄粉蚜发生动态及发生数量的影响,采用系统调查法,在河北省赵县分别选择清耕梨园、人工种草梨园、自然生草梨园,对梨木虱和梨黄粉蚜不同发育阶段的发生数量以及各虫态的总发生数量进行了调查。结果表明:不同生草模式的梨园,2种害虫卵、若虫、成虫的发生动态趋势均基本一致,但是在某个具体时期上的发生数量存在一定差异。无论是人工种草,还是自然生草,梨园覆草后梨木虱和梨黄粉蚜的各虫态总发生数量均较清耕梨园减少,说明梨园人工种草或自然生草均可增加梨园生境的多样性和物种丰富度,改善梨园群落结构的稳定性,是一种很好的害虫生态调控措施。In order to clarify the effects of grass growing in pear orchard on the occurrence dynamics and quantity of Psylla chinensis and Aphanoaigma jakuauiense,a systematic investigation method was used to investigate the occurrence quantity of the two pests at different development stages and the total occurrence quantity of each insect state in clean tillage pear orchard,artificial grass growing pear orchard and natural grass growing pear orchard in Zhao County,Hebei Province.The results showed that the occurrence dynamics of eggs,nymphs and adults of the two pests were basically the same in pear orchards with different grass growing modes,but there were some differences in the number of pests in a specific period.Whether in artificial grass growing or natural grass growing pear orchards,the total occurrence of each insect state of the two pests was lower than that in clean tillage pear orchard,indicating that artificial or natural grass growing in pear orchards can increase the diversity and species richness,improve the stability of community structure,so it was a kind of ecological controlling measures for pest controlling.
