第４代棉铃虫不同方法诱蛾量与田间卵量消长相关性研究结果表明：性诱剂前３ｄ诱蛾量与田间当天卵量相关性强、与后３ｄ卵量相关性差。相关系数１９９６年分别为０．８９３０、０．５６１８，１９９７年分别为０．９４７１、０．３０１８。杨树枝把前３ｄ诱蛾量与田间当天卵量的相关性比与后３ｄ卵量的相关性差。相关系数１９９６年为０．７２１３、０．９８２２，１９９７年为０．６９３９、０．９２７７。性诱剂蛾高峰期和高峰日与田间卵量的高峰期和高峰日基本吻合，蛾高峰期早卵高峰期０～２ｄ；杨树枝把则早２～４ｄ。性诱剂诱蛾在指导田间药剂防治上比杨树枝把诱蛾更有意义。
The results showed that there was a strong correlation between the number of induced moths and the number of eggs in the field and the correlation between the amount of moths and the number of eggs in the first three days. The correlation coefficient was 0.8930, 0. 5618 in 1996 and 0.9471, 0.3018 in 1997 respectively. The correlation between the amount of the first 3d moths and the number of eggs in the field on the same day was not as good as that between the number of the third and the third. The correlation coefficient was 0.7213, 0.9822 in 1996 and 0.6939, 0.9277 in 1997. The lures and peak days of sexual lure moths at the peak and peak days were basically in line with the peak day, and the early peak of the moths peaked at 0 ~ 2 days and that of the poplar branches at 2 ~ 4 days earlier. Sexual Attractants Moths are more instructive in directing the field agent control than the poplar branches.
