| 中文摘要: |
| 在室内研究了捕食性天敌泛希姬蝽成虫对中国梨喀木虱成虫的捕食作用。结果表明，泛希姬蝽对中国梨喀木虱成虫的捕食功能反应符合HollingⅡ型反应,拟合的圆盘方程为Na=0.753 7N/(1+0.018 9N)，泛希姬蝽对自身密度的功能反应用Watt模型拟合为A=28.724 6P-0.702，其捕食作用率与个体间相互干扰作用的关系用Hassell-Varley的干扰反应模型拟合为E=0.614 5P-0.224 7。 |
| 英文摘要: |
| The predation of Himacerus(Himacerus)apterus adults on Cacopsylla chinensis adults was studied in the laboratory.The results showed that the functional response of H. (H.)apterus adults to C. chinensis adults fitted to Holling typeⅡmodel and the equation was Na=0.753 7N/(1+0.018 9N). The density functional response of H.(H.)apterus could be fitted to the Watt model, A=28.724 6P-0.702. The relationships between predation efficiency and individual interference could be fitted to the Hassell-Varley model E=0.614 5P-0.224 7． |
