摘要
本文研究了白蜡虫EriceruspelaChavannes产卵期雌虫密度对黑缘红瓢虫ChilocorusrubidusHope发育历期的影响。结果表明 ,黑缘红瓢虫 1 - 4龄幼虫发育历期与白蜡虫产卵期雌虫密度呈幂函数关系 :Y =aX-b,相关系数达极显著。经回归系数显著性检验 ,对白蜡虫被捕食率造成显著影响的因子主要有白蜡虫密度 (X1)、黑缘红瓢虫 3、4龄幼虫和成虫密度 (X4、X5、X6)。白蜡虫产卵期雌虫、黑缘红瓢虫各龄幼虫和成虫自身的交互作用均达显著水平 ,但这些因子之间的交互作用均未达显著水平。剔除不显著因子后的优化模型为 :Y =0 .7438- 0 .0 62 5X1+ 0 .0 51 7X4+ 0 .0 70 8X5+ 0 .0 4 83X6- 0 .0 81 7X21- 0 .0 392X22 - 0 .0 2 57X23- 0 .0 392X240 .0 392X25- 0 .0 392X26。
This paper deals with relationship of female density of white wax insect, Ericerus pela, in oviposition period and the development period and predation of the lady beetle, Chilocorus rubidus. The results showed that the relationship of the development period of the lady beetle and the female density of white wax insect in oviposition period was power function:Y=aX -b . The chief factors which noticeably affected the lady beetle preyed on white wax insect were the female density of white wax insect in oviposition period (X 1), the third, fourth instar larvae and adult density of the lady beetle (X 4,X 5,X 6). The mutual effect of female of white wax insect in oviposition period (X 1 2), lst-4th instar larvae and adult of the lady beetle(X 2 2,X 3 2,X 4 2,X 5 2 and X 6 2) were all noticeable respectively, but the mutual effects among these factors were all unnoticeable. The model which unnoticeable factors were removed was:Y=0.7438-0.0625X 1+0.0517X 4-0.0708X 5+ 0.0483X 6-0.0817X 1 2-0.0392X 2 2-0.0257X 3 2-0.0392X 4 2-0.0392X 5 2-0.0392X 6 2.
