Abstract: [Objective] Through the research on the effects of different storage methods on the pupation and eclosion development of overwintering larvae,the project aims to explore providing a kind of reasonable method for storing maize straws in Xinjiang,which might reduce the amount of overwintering larvae.[Method] Through comparison and analysis of the amount of overwintering larvae in 100 plants,pupation rate,emergence rate and mortality by different stroage methods(standing,stacking,sealing),in order to put forward a kind of reasonable storage method of maize straw.[Result]Synthetically considering the data of 2014,2015 for two consecutive years showed that: The average number of live overwintering larvae in 100 plants,live pupa number in 100 plants,pupation rate,emergence rate and mortality under sealing were reduced by 59.58;and 43.52;,90.21;and 92.33;,19.87;and 17.99;,13.77;and 11.79;,which compared with standing and stacking respectively,and its average mortality rate was increased by 39.78;and 39.78;respectively.[Conclusion]The average number of live overwintering larvae in 100 plants,live pupa number in 100 plants,pupation rate,emergence rate and mortality under sealing were all significantly greater than those of standing and stacking(P<0.05);The sealing treatment can increase partly the total mortality of overwintering corn borer,and reduce its pupation rate.So in actual production,the maize straw is not recommended to wintering in the form of standing treatment and preferred to sealing treatment,which can reduce its overwintering larvae survival and emergence rate.

摘要： [目的]研究玉米秸秆不同储放方式对越冬代玉米螟幼虫化蛹及羽化的影响,探索一种控制新疆玉米螟越冬基数的合理储放方式.[方法]2014、2015年对竖放、堆放和封闭储放下的秸秆百株幼虫数、化蛹率、羽化率及死亡率等指标进行比较分析,提出一种压低玉米螟越冬基数的合理储放方式.[结果]与竖放、堆放处理相比,经封闭处理越冬后的秸秆,其平均百秆活幼虫数、百秆活蛹数、化蛹率及羽化率分别降低59.58;、43.52;,90.21;、92.33;,19.87;、17.99;,13.77;和11.79;,其平均死亡率分别增加39.78;、35.44;.[结论]玉米秸秆以竖放方式进行越冬的平均百秆活幼虫数、活蛹数、化蛹率及羽化率均显著大于堆放、封闭处理(P<0.05);封闭处理则可在一定程度上提高越冬玉米螟的总死亡率,降低其化蛹羽化率.在生产实际中,秸秆不以竖放方式进行越冬,而优先对其进行封闭处理,以降低其越冬幼虫成活和羽化基数.
