| 摘 要： | 为探明异色瓢虫(Harmonia axyridis Pall.)成虫对榆紫叶甲(Ambrostoma quadriimopressum Motschulsky)卵的控制效能,开展了异色瓢虫成虫对榆紫叶甲卵的捕食功能反应与寻找效应研究。结果表明:在供试温度下,异色瓢虫捕食功能反应符合Holling II型方程,χ2适合性检验表明圆盘方程的预测值与实测值相符;在相同温度下,异色瓢虫成虫的捕食量随着猎物密度的增加而增大;搜寻效应随着猎物密度的增加而降低;在供试温度范围内,随温度的升高,异色瓢虫成虫对榆紫叶甲卵的捕食量增加;在相同猎物密度条件下,随异色瓢虫成虫密度的增大,其平均捕食量逐渐减少,捕食作用率也相应降低,捕食作用率(E)与异色瓢虫成虫密度(P)的关系为E=23.648 6P-0.220 9。

| Abstract: | Functional response and searching rate of adult Harmonia axyridis to eggs of Ambrostoma quadriimopressum were studied in order to learn the control efficiency of H.axyridis to A.quadriimopressum.Results showed that the functional response could be described by Holling II-type equations at all the tested temperatures.Chi-square test shows that the theoretical value calculated by the fitted Holling disc equation agrees well with the observed values.At the same temperature,the predation capacity of adult H.axyridis to A.quadriimopressum eggs increased with increasing density of A.quadriimopressum eggs;however,the searching rate decreased.The predation capacity of adult H.axyridis increased with increasing temperature at 15-30 degrees C.At the same prey density,the average predation capacity and predation ratio of adult H.axyridis decreased with increasing density.The relationship between predation ratio(E) and density(P) of adult H.axyridis could be described by the equation of E=23.6486P-0.2209. |
