摘要
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。
The relationship between effective temperature summation for pupa deve lopman at over winter and insect in high period of soybean root miner was observed during 1979-1983 .The result showed as follows:The temperature for pupa development was 9.2±1℃ and total effective temperature summation was 181±12.6 day/degree.Formula of forecast for effective temperature summation was gained combining climatic data collected from Juzan Meleological station,Jilin during 1979-1983,It is highly agreement for the forecast formula with the practival pest occurrence in field.
