Abstract
In cotton production, there are many factors that can reduce crop yield. One important cause is arthropod insects. Insects that cause loss to the fruit are frequently more destructive than those that damage leaves, stems, and roots. This review describes integration of pest control tactics directed against the bollworm pest complex. Different IPM treatments consisting of three sprays alternately at 10 days interval in comparison to unsprayed Non-IPM plot (control) have been evaluated for two consecutive years 2012-13 and 2013-14. The effectiveness against bollworms complex was evaluated in term of square and boll damage in both the plots. In the result, the low incidence of bollworm complex was recorded in IPM plot over non-IPM plot. The minimum square damage, green boll damage, open boll damage and locule damage was recorded in IPM plots in comparison to non-IPM plot from July to October. The minimum square damage (5.13%), green boll damage (4.1%), open boll damage (13.45%) and locule damage (4.43%) was recorded in IPM plot, which was recorded higher in non-IPM plot.
