Study on the Controlling Index of Cotton Boll Worm

Ding Kexue et al (Mengcheng County Extension Center of Agricultural Science, Mengcheng 233500)  
The controlling index of cotton boll worm was studied based on the research on the relationship among the number of cotton boll worm egg, the number of natural enemy and cotton yield. The invesigation of the number of egg and natural enemy per 100 plants at the peak period of the laying egg showed that: when the number of egg - the number of natural enemy×22≥8, the controlling measure should be taken.
