红褐斑腿蝗耐温性的初步研究

A PRELIMINARY STUDY OF TEMPERATURE TOLERANCE IN CATANTOPS PINGUIS (STAL)

本文研究了浙江农田常见的蝗虫——红褐斑腿蝗在高温下的半致死温度，发现在雌、雄间存在差异。以处理时间为０．５ｈ为例：雄性的ＴＬ５０＝４９．０℃，而雌性的ＴＬ５０＝５１．０℃。同样，处理时间的长短也会影响到ＴＬ５０的大小。本文建立了ＴＬ５０与处理时间的函数关系，回归方程为雄性：ｙ＝－１．１ｘ＋４９．６５；雌性：ｙ’＝－１．３４ｘ’＋５１．５。在低温冷冻复苏实验中，本文还研究了蝗虫在不同低温下的复苏情况，发现－７．０℃是雄虫耐受低温的一个转折点，而雌虫的转折点则为－７．５℃．

The median lethal temperature of Catantops pinguis(Stal) under high temperature has been studied.The result shows that there is difference between both sexes.The relation between T L50 and time of treatment can be shown as following regression equations: males:y=-1 1x+49 65 females:y ’=-1 34x ’+51 5 The anabiosis of acridoids after suffered cold treatment has also been described.
