1979—1983年作者研究了大豆根蛇潜蝇越冬蛹的有效积温与大豆根蛇潜蝇成虫发生盛期的关系。明确该蛹发育起点温度为9.2±1℃,总有效积温为181±12.6日度;提出有效积温预测式,并结合该地区1979—1983年气象资料,验证田间实际发生情况,结果吻合程度很高。

Results from experiments under controlled temperature showed that there exists a functional relationship between the development durations of egg, larvae and pupae of Agasicles hgrophila and the temperature.From 22 to 32℃,the development durations are obviously shortened with increasing temperature.The larval period has three instats and endures 8.8 days.The life span of adult is related to temperature and sex,and the females live longer than the males.The period of pre oviposition varies...

Results from experiments under controlled temperature showed that there exists a functional relationship between the development durations of egg, larvae and pupae of Agasicles hgrophila and the temperature.From 22 to 32℃,the development durations are obviously shortened with increasing temperature.The larval period has three instats and endures 8.8 days.The life span of adult is related to temperature and sex,and the females live longer than the males.The period of pre oviposition varies from 1.5 to 5.0 days, and that of oviposition from 11.5 to 116.0 days.The initial temperature of egg,larvae and pupae development is 12.4 and 12℃, and the effective accumulative temperature of them is 69.192 and 125℃,respectively.

国槐、龙爪槐是重要的园林绿化树种,近年来常遭到槐尺蛾的严重危害,影响绿化效应和观赏价值。该虫每年发生6代,蛹重为(0.1923±0.0325)mg/只;产卵量为(636.43±219.76)粒。经多代饲养测定,蛹的发育起点温度C=(13.10±1.59)℃,有效积温K=92.16±4.25(DD);卵发育起点温度C=(13.13±1.75)℃,有效积温K=54.59±2.57(DD)。由此建立数学预测式经1997年的验证,其结果符合实际情况。
