摘要
经室内自然变温条件下 ,对华山松木蠹象各虫态的发育起点温度和有效积温进行测定。据此 ,分别提出该虫卵、幼虫、蛹和一世代的有效积温预测式 :卵N =12 4 15± 2 5 77/〔T - (9 83± 2 6 4)〕 ,幼虫N =2 0 1 86±5 6 3/〔T - (19 5 8± 0 86 )〕 ,蛹N =2 5 5 71± 39 14/〔T - (12 0 6± 1 41)〕 ,一世代N =5 2 2 14± 14 5 8/〔T -(19 38± 0 87)〕。
Under natural temperature indoor, original temperature and effective accumulated temperature for various development stages of Pissodes punctatus Longer, Situ et Zhang were determined.? Based on these, the predict formula for effective accumulated temperature of ovum, larva, pupa and first generation have been proposed, which are N=124 15±25 77/〔T-(9 83±2 64)〕 for ovum, N=201 86±56 3/〔T-(19 58±0 86)〕 for larva, N=255 71±39 14/〔T-(12 06±1 41)〕 for pupa and N=522 14±14 58/〔T-(19 38±0 87)〕 for the first generation.?
