摘  要:
通过对春小麦3种蚜虫发生量的田间调查可知,温度、湿度、降雨量等对3种蚜虫的消长规律均有不同程度的影响,其中,麦二叉蚜(Schizaphis graminum Rondani)适宜生长发育的温度为25℃左右,相对湿度为55%~63%;麦长管蚜(Macrosiphum avenae Fabricius)在25℃以下,相对湿度55%以下繁殖速率加快;禾谷缢管蚜(Rhopalosiphum padi L.)则在30℃左右,相对湿度60%以上繁殖速率最快。

摘  要:
Field investigation on population dynamics of three species of spring wheat aphids showed that temperature humidity and rainfall, etc, had different effects on the population dynamic of three species of aphids. The temperature of 25 # and relative humidity of 55% - 63% is beneficial to Schizaphis graminum Rondani.The breeding rate of Macrosiphum avenae Fabri-cius be accelerated under 25# and 55% relative humidity. The best breeding rate of Phopalosi-phum padi L. is at 30 # and over 60% relative humidity.
