摘要
本文研究了不同温度和光照时间对麦长管蚜〔Macrosiphum avenae(Fabricius)〕和禾谷缢管蚜(Rhopalosiphum padi(Linnaeus)〕种群存活率、平均产雌率、内禀增长率等种群参数的影响.结果表明:在12h 光照下,麦长管蚜穗型蚜和禾谷缢管蚜种群的内禀增长率在25℃达最大值,而麦长管蚜苗型蚜种群的内禀增长率则在18℃达最大值。在20℃条件下,禾谷缢管蚜和麦长管蚜苗型蚜种群的内禀增长率分别在8和15h 光照时达最大值。同时,根据内禀增长率计算出了麦蚜种群在不同温度下对不同死亡率干扰的反应时间。对于实验结果在生产实践中的应用,作者也作了详细的阐述与讨论。
The paper deals with the influence of temperature and photoperiod on suchpopulation parameters of Birdcherry aphid R.padi(L.)and English grain ap-hid M.avenae(F.)as rate of survivorship,average reproduction,and theintrinisic rate of increase(r_m).The results Show that the r_m of R.padi andear-type of M.avenae reach the maximum at 25℃ and the r_m of seedling-typeof M.avenae reaches the maximum at 18℃ when photophase is i2 hours;the r_mof R.padi and M.avenae reach the maximum at 8 and 15 hours of photophaserespectively when temperature is 20℃.In addition,the responsive time ofpopulation to the disturbances of mortalities has been calculated out based on r_m.
