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.ResultSynthetically 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.ConclusionThe 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.
