斯氏钝绥螨以截形叶螨为猎物的实验种群生命表
Experimental Life Table for Population of Amblyseius swirskii (Athias-Henriot) Fed on Tetran ychus truncatus (Ehara)
摘要
Abstract
The parameters of a life table with an experimental population of Amblysieus swirskii (Athias-Henriot) were studied. At 6 constant temperatures (I. E. , 15℃, 18℃ , 20℃, 25℃, 30℃ and 35℃), A. Stuirskii were fed on Tetranychus truncatus (Ehara) to evaluate the feasibility of utilizing the predatory mites to control the spider mites. The in-laboratory experiments showed that, at 15℃, the predatory mite could develop, but its survival rate was less than 43. 33%, and there were irregularities observed in its egg-laying. The temperature range of 18 - 35'C was considered appropriate for the predatory mite' s development. And, within the range, the time for A. Swirskii to develop shortened as the temperature rose-the longest (31. 50 days) at 15'C and shortest (5. 75days) at 35'C for the females, and the longest (20. 00 days) at 15'C and shortest (3. 96 days) at 35'C for the males. The highest intrinsic rate of natural increase (rm_0. 1976) and the highest finite rate of increase (A=l. 2185) were observed at 35'C. The highest sex ratio (1. 73 ' 1) and the highest net reproductive rate (R0=36. 8600) were found at 25℃. And, the highest mean number of eggs (57. 60 eggs per female) occurred at 25℃.关键词
