abstract
Extensive use of pesticides in agriculture provides us a rationale for resistance development in cotton cropping system. Neonicotenoids pesticides including imidacloprid have shown resistance evolution in insects in cotton cropping system. So in these studies, imidacloprid was tested against ducky cotton bug at recommended, low and high concentrations. Imidacloprid was tested at concentrations of 0.1, 0.2, 0.3 ml. Each test was replicated three times in laboratory to observe the mortality of ducky cotton bugs. Mortality results showed that all bugs were dead in a limited time interval in each tested treatment as compared to control, though slightly lower at lower concentration. These results have explicitly shown that imidacloprid not resulted in resistance evolution in dusky cotton bugs in cotton cropping system. These results can further be used to test other sucking pests to observe either pesticides are resulting or not a counterproductive impacts. A hawkish stance should be asserted to observe the resistance evolution in insects against commonly sprayed pesticides.
