Abstract
The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), has become a widespread serious pest and causing economic losses. In an attempt to control this different organic amendments, seed treatment practices, plant products and insecticides were evaluated. The highest kapas yield of 7.8 q/ ha was recorded in flonicamid treated plots followed by 7.7 q/ ha in thiodicarb treated plots as against 2.8 q/ ha in control. Cost-benefit ratio was also higher in these treatments recording 1.83 and 1.81 CBR, respectively. Though the insecticides were found effective, organic amendments + foliar spraying of plant products treatments was safer to coccinellids recording 13.5 and 14.2/ 10 plants. The same trend was also observed with regard to Chrysoperla zastrowi sillemi and spiders coccinellids varied from 2.3 to 5.3, C. zastrowi sillemi from 2.1 to 3.2 no’s/ 10 plants in various insecticides sprayed fields as against 8.35 in control. Similarly, the population of spiders varied from 0.3 to 0.5 no’s/ 10 plants as against 2.47 in control.
