摘要
本研究分别对有效交配后,单头饲养和配对饲养的蠋蝽雌虫寿命和繁殖力参数进行统计分析。试验结果表明:有效交配后,单头饲养的蠋蝽雌虫平均产卵量为343.80粒、平均产卵次数14.83次、平均寿命为53.13 d,分别显著高于对照组(配对饲养)的平均产卵量(258.20粒)、平均产卵次数(10.63次)和平均寿命(45.30 d);蠋蝽的单次产卵量、卵孵化率、卵直径均随产卵次数增加而减小,其中单头饲养组的减小趋势显著;单头饲养组蠋蝽的卵孵化率为59.58%,显著低于对照组的68.89%,而单头饲养组蠋蝽单雌所产卵的孵化数192.95头较对照组的177.87头更高。蠋蝽雌虫有效交配后进行单头饲养有利于延长蠋蝽寿命、提高其繁殖力。
The parameters of longevity and reproductive capacity of female Arma chinensis raised individually were analyzed.The results showed that,after valid mating,every female in individually rearing group laid 343.80 eggs in 14.83 times,with a longevity of 53.13 d,which were significantly higher than in the control group(258.20 eggs in 10.63 times and 45.30 d,respectively).The fecundity,egg hatching rate and egg diameter all decreased with the spawning times,and the decreasing trend in individually rearing group was more pronounced.The egg hatching rate in individually rearing group was 59.58%,which was significantly lower than 68.89%in control group,but the number of eggs hatched in individually rearing group(192.95)was higher than that in control group(177.87).The individually reared females tended to prolong their longevity and improve their reproductive capacity.
