摘　　要：为明确低温对绿盲蝽生长发育和繁殖的影响,于室内观察了绿盲蝽(Apolygus lucorum)经低温(0、5、10、15℃)处理后若虫发育、成虫寿命及生殖参数的变化。结果表明,绿盲蝽若虫羽化率随温度降低而显著下降,0℃和5℃低温下多数若虫未羽化即死亡,10℃和15℃处理的羽化率分别是26℃对照的19.10%和75.71%。低温显著延长绿盲蝽若虫历期,10℃和15℃低温下若虫历期分别是26℃对照的1.80和1.33倍。绿盲蝽雌雄成虫寿命在0℃~26℃随温度升高先延长后缩短,在10℃时达到最高值,分别是31.75 d和30.61 d。雌虫产卵量和卵孵化率随温度的降低而显著下降;5℃、10℃和15℃处理的产卵量分别是26℃对照的3.92%、34.53%和51.56%;5℃低温处理下没有卵孵化,10℃和15℃处理下卵孵化率分别是26℃对照的8.12%和21.36%。以上研究结果表明,低温抑制绿盲蝽若虫羽化这一变态发育过程,且随处理温度的降低,抑制程度增加;同时,低温对成虫生殖也有抑制作用,抑制程度随温度降低而增加。To investigate the effect of low temperature on the growth,development and reproduction of Apolygus lucorum,we measured the nymph development,adult lifespan and fecundity in the laboratory under low temperature stress(0,5,10 and 15℃).The results showed that the eclosion rate of nymph decreased significantly with decreasing temperature.Most nymph died before eclosion at 0℃and 5℃,and the eclosion rate at 10℃and 15℃was 19.10%and 75.71%of that at 26℃,respectively.The duration of nymph at low temperature was significantly prolonged.The duration of nymph at low temperature of 10℃and 15℃was 1.80 and 1.33 times that of control at 26℃,respectively.From 0℃to 26℃,the longevity of male and females first increased and then decreased with increasing temperature,reaching the highest value at 10℃,which were 31.75 days and 30.61 days,respectively.The number of eggs laid by female and the rate of egg hatching decreased significantly with decreasing temperature.The oviposition of A.lucorum at 5℃,10℃and 15℃was 3.92%,34.53%and 51.56%of the control at 26℃,respectively.No eggs hatched at 5℃,and the hatching rate at 10℃and 15℃was 8.12%and 21.36%of that at 26℃,respectively.All the results showed that low temperature inhibited the eclosion of A.lucorum nymph,and the degree of inhibition increased with the decrease in treatment temperature.At the same time,low temperature also suppressed adult reproduction,and the degree of inhibition increased with decreasing temperature.
