摘要: 本试验测定了不同发育阶段柑桔白轮蚧的发育起点温度(C)和有效积温(K)。结果表明:在18-30℃范围内,该蚧的发育历期随温度的升高而缩短,发育速率与温度呈直线关系。得到了柑桔白轮蚧各虫态及雌虫全世代的发育起点温度和有效积温。结合雅安地区气象资料推算出该蚧年发生代数为4-5代。

Abstract: Aulacaspis citri Chen is one of important pest of citrus. The experiment Contains: estimating developmental threshold(C), effective thermal constant(K) and generation numbers of one year. The results showed that under 18-30℃ the duration decreased and the development rate increased rectilinearly with temperature. The developmental threshold and thermal constant of each development stage were obtained. Generation numbers are 4-5 in Yaan.

Key words: CITRUS, AULACASPIS CITRI CHEN, DEVELOPMENTAL THERSHOLD, EFFECTIVE THERMAL CONSTANT
