摘要
Temperature dependent development in the Asian corn borer, Ostrinia furnacalis (Guenee) was determined at nine constant temperatures between 10℃ and 34℃. Except for 10℃ development of all life stages occurred at the temperatures tested, however, mortality was significantly great at the extreme temperatures(12℃ and 34℃). Egg, larvae and pupae duration accounted for 17%, 57% and 25% of total one of immature stage, respectively Lower developmental thresholds estimated to be 10 38, 10 06 and 11 07℃ for eggs, larvae and pupae, respectively. Upper limited thresholds were 28 00, 31 00 and 31 00℃ for eggs, larvae and pupae, respectively. The heat unit requirements for egg stage were 79 15 degree days, for larval stage were 339 73 degree days, and for pupal stage were 128 82 degree days, respectively. Overall, heat unit requirements for development from egg to adult were 539 91 degree days between lower developmental threshold 10 35℃ and upper limited threshold 32℃.
利用10~34℃的9个恒温对亚洲玉米螟Ostriniafurnacalis(Guenee)发育与温度的关系进行了研究。亚洲玉米螟除了在10℃不能发育以外,在其余8种恒温中均可发育,但其死亡率在12℃和34℃中较高。从产卵到成虫羽化,卵期占整个发育过程的17%,幼虫期占57%,蛹期占25%。最低发育起点温度卵期为1038℃,幼虫期为1006℃,蛹期为1107℃。高温限制温度卵期为2800℃,幼虫期和蛹期均为3100℃。卵期有效积温为7915日度,幼虫期为33973日度,蛹期为12882日度。从产卵到成虫羽化整个过程的发育起点温度为1035℃,高温限制温度3200℃,有效积温为53991日度。
