苏铁肾盾蚧室内繁殖研究

[目的]探讨苏铁肾盾蚧作为盾蚧类害虫天敌中间寄主的可能性。[方法]进行繁殖材料筛选、温度对繁殖的影响等试验。[结果]用红薯饲养苏铁肾盾蚧效果不理想,而南瓜或马铃薯饲养苏铁肾盾蚧的固定率、存活率、每雌产卵量和历期等参数的差异不显著,说明2种材料饲养苏铁肾盾蚧的效果相同;苏铁肾盾蚧的固定率、存活率、每雌产卵量随温度的增加而增大,到25℃达到最大,此后随温度的增加而降低,而历期随着温度的升高而缩短。因此,25℃是饲养苏铁肾盾蚧的最佳温度。[结论]该蚧虫不是最佳的盾蚧类害虫天敌的中间寄主。

Propagation of Aonidiella inornata Mackenzi on the Indoor

[ Ojective ] To explore the possibility of Aonidiella inornata Mackenzi as intermediate host of natural enemy of Diaspididae. [ Method] Propdgation material screening and temperature effects experiments were conducted. [ Result ] Experimental results showed that, the effect of propagating A. inornata with the sweet potato was not ideal. However, the fixed rate, survival rate, fecundity per female and du- ration parameters were not significantly different with pumpkin or potato rearing the A. inornata, which indicated, that the effect of such two materials propagating A. inornata was the same. The fixed rate, survival rate and fecundity per female increased with the raise of temperature, and then decreased with the fall of temperature after reaching the maximum temperature of 25 ℃. The duration was shortened with the increase of the temperature. Therefore, 25 ℃ was the optimal temperature for feeding the A. inornata. [ Conclusion] Aonidiella inornata wasn＇t the optimal intermediate host of natural enemy of Diaspididae.
