| 摘 要： | 室内研究了蓝蝽Zicrona caerula(Linnaeus)对马铃薯甲虫Leptinotarsa decemlineata(Say)低龄幼虫的捕食功能反应和选择效应。HollingII型圆盘方程和HollingⅢ型新模型拟合结果共同显示,蓝蝽若虫对马铃薯甲虫1龄幼虫的捕食量随着龄期的增加而增大;4、5龄若虫及成虫的捕食量均在17头以上。由HollingII模型获得蓝蝽对马铃薯甲虫1龄幼虫的控制能力为2龄<3龄<4龄<5龄<成虫;随着食物密度的增加,蓝蝽各虫态的寻找效应逐渐下降。田间防治马铃薯甲虫1龄幼虫时,2～5龄蓝蝽若虫及成虫的最佳益害比应该分别为1∶2、1∶4、1∶13、1∶14、1∶13,然而,食物选择效应显示蓝蝽原生境中猎物-兰叶甲可能会对防治产生影响。 |

| Abstract: | The prodatory functional response of Zicrona caerula(Linnaeus) larvae and adults to Leptinotarsa decemlineata(Say) low instar larvae and the selection of Zicrona caerula(Linnaeus) to two kind of insect food were explored in laboraty.Both results from HollingⅡdisc equation and Holling III new model show that the maximum predation capacities to 1st instar Leptinotarsa decemlineata(Say) larvae increased strongly along with the larva growth,and the maximum predation capacities of 4th to 5th instar larvae and adults are above seventeen.According to the results of HollingⅡmodel pattern,the predacious abilities of Zicrona caerula(Linnaeus) to 1st instar Leptinotarsa decemlineata(Say) larvae are 2nd instar﹤3rd instar﹤4th instar﹤5th instar﹤adults;the hunting effect to Leptinotarsa decemlineata(Say) larvae decreased along with the increase of prey density.The optimal ratios of 2nd to 5th instar nymphs and adults of Zicrona caerula(Linnaeus) to 1st instar Leptinotarsa decemlineata(Say) larvae released in field are 1∶ 2,1∶ 4,1∶ 13,1∶ 14,and 1∶ 13.While the control effect may be influenced by the original habitat prey(bule leaf beetle) of Zicrona caerula(Linnaeus). |
