摘要：为了明确保存时间及降雨对花绒寄甲卵孵化率的影响,设保存时间30,60和90 d,模拟连续降雨1,3,5,7 d共7种处理,测试花绒寄甲卵在野外的孵化率。结果显示:保存30 d,平均校正孵化率为49.39%;保存60 d,平均校正孵化率为36.93%;保存90 d,孵化率为0,显著低于30 d和60 d;保存30 d与60 d之间,无显著性差异。保存30 d的卵模拟降雨1 d,平均校正孵化率为47.79%;模拟连续降雨3,5,7 d,平均校正孵化率分别为33.24%,37.05%和27.97%。模拟降雨与对照之间无显著性差异,模拟降雨不同天数之间亦无显著性差异。由此可见,保存时间对花绒寄甲卵野外孵化率具有很大的影响,而野外降雨对花绒寄甲卵孵化率的影响可能很小。
In order to clarify the effect of preservation time and rainfall on egg hatchability of Dastarcus helophoroides Fairmaire（ Coleoptera ：Bothrideridae） in field, the egg hatchability in field were studied under the condition of preservation time 30,60,90 d and simulated rainfall 1,3,5,7 d. The results showed that the average corrected egg hatchability was 49. 39% when stored for 30 d,36.93% for 60 d and 0 for 90 d; that of 90 d was significantly lower than those of 30 d and 60 d, no significant difference between those of 30 d and 60 d. The average corrected egg hatchability was 47.79% for 1 d simulated rainfall,33.24% ,37.05% and 27.97% for 3,5 and 7d respectively; there were no significant differ-ences between the 4 simulated rainfall treatments and the control or among the 4 treatments. Hence we concluded that preservation time had great impact on egg hatchability of D. helophoroides in field and the impact of rainfall might be small.
