Evaluation of sucking and chewing types’ insect pests of cotton crop through integrated pest managements (IPM) Techniques

Abstract

Cotton is most important cash crop in the world and also in Pakistan. But due to attack of major insect pest of cotton crop reduce the quality and quantity. Massive use of pesticides to control these insect pest has negative impact on the environment and also expensive for the farmers community. So present research was designed to find out the best method of integrated pest management (IPM) techniques to minimize the synthetic organic pesticides. In present research Three IPM methods (Sticky traps, Light Traps and organic and inorganic pesticides) was used to the management of major insect pest of cotton.  Five various colours (Yellow, Green, Blue, Black, and Red) sticky traps, Five different colours (Red, Blue, Yellow, Green and White) of light traps, three organic pesticides (Eucalyptus, Tobacco and Neem Seed) and three synthetic pesticides (Emmamectin, Benzoate, Profenofose and Bifenthrin) was used to compared control group. In present results we observed a maximum pest population of white fly, jassid, thrips, grasshopper and leaf hopper was found on yellow, blue and green sticky traps and minimum pest population was noticed on Red and Black sticky traps. Similarly a maximum pest population of pink bollworm, spotted bollworm and American bollworm moths catch by Blue, White and Yellow light traps colours, while a lowest pest population of  all three bollworm moth catch by Green and  Red colure of lights. A significantly reduce pest population of, whitefly, jassid, thrips, aphids, grass hopper, leaf hopper, pink bollworm, spotted bollworm and American bollworm was found on synthetic pesticides (Emmamectin, Benzoate, Profenofose and Bifenthrin) and organic pesticides (Eucalyptus, Tobacco and Neem Seed)  as contrast with control group. We concluded that use of sticky traps and light traps can suppress the pest population of both sucking and chewing type insect pest of cotton crops. Similarly all three organic pesticides (Eucalyptus, Tobacco and Neem Seed) have ability to reduce the pest population of insect pest and also can reduce the use of hazard insecticides.
