黄地老虎在新疆多以老熟幼虫越冬,越冬代化蛹整齐,可用数学方法进行模拟,预报发蛾盛期及产卵为害盛期。以1980—1981两年在墨玉城郊苜蓿田埂上调查的化蛹进度,选用对数曲线方程法及概率单位直回归法进行配合,再以卡方(x~2)值测定适合程度,然后进行校正,求出概率单位直回归方程式。化蛹进度的调查方法;从3月15日开始,每隔一天,每次 Most tiger tiger in Xinjiang overwinter larvae mature, overwintering pupal neat, mathematical methods can be used to simulate the forecast moths and spawning period of peak Sheng. In the 1980-1981 two years in Moyu suburbs of alfalfa 调 on the investigation of pupation progress, use of logarithmic curve equation method and probability units of direct regression method to cooperate with chi-square (x ~ 2) value determination of suitability, and then Calibration, find the unit of probability straightforward regression equation. Method of investigating pupa progress; starting from March 15, every other day, each time
