摘要
在 10～ 2 6℃恒温条件下 ,角倍蚜雌蚜的世代生长发育历期符合总积温法则 ,发育起点温度为 3.6℃± 1.1℃ ,有效积温为 358.7日度 ;应用中可根据理论公式和倍蚜的生物温度参数预测雌蚜的世代发育历期 ,并通过调控存放虫袋环境温度的方法控制性蚜的发育速率 ,使干母的发生期应合盐肤木的最适致瘿结倍物候期 ,提高倍蚜虫袋的挂放效果 ;干母的耐饥饿能力弱 ,室温存放只能存活 2 d左右 。
At the condition of 10～26 ℃,the development period of female generation corresponds to the accumulated temperature theorem.The threshold of development of female aphid is 3.6 ℃±1.1 ℃,the effective accumulated temperature is 358.7(d ℃).According to the parameters of biotemperature and theoretical equation,the development period of female generation can be predicted.The emergence period of fundatrigena can be controlled so as to correspond with the suitalbe phonological period of Rhus chinensis ,by means of regulation the storage temperature condition.It would achieve good result if the emergence period of fundatrigena corresponding to the phonological period of host tree,when the 3rd～8th leaves of Rhus chinensis is breaking successively.The ability endurance to starvation is very weak.Fundatrigena can only survival around 2 d.Therefore,the bags should be put up on to host tree without any delay at the beginning of the emergence period.
