- Abstract
Cotton mealybug (CMB), Pheanacoccus solenopsis is highly deleterious insect pests of agricultural crops. It is polyphagous by nature and can feed on diversity of host plants. Different concentrations of Pyriproxyfen and Buprofezin are Insect Growth Regulator (IGR) were bio-assayed against 3rd instar of CMBat Integrated Pest Management Laboratory, Department of Entomology, University of Agriculture, Faisalabad, during 2016. The results revealed that mortality of 3rd instar of P. solenopsis increased with increase in concentration of Pyriproxyfen and Buprofezin at three days of post application interval (PAI). Pyriproxyfen 0.5% and Buprofezin at 2% concentration induced mortality of P. solenopsis up to (82.52%) and (87.60%) respectively at PAI of 3 days after application. At 0.25%concentration of Pyriproxyfen and 1% of Buprofezin mortality of CMB was observed up to 59.72% and 63.04%respectivelyon 3rdday after application. Similarly Pyriproxyfen at 0.125% concentration and Buprofezin0.5% resulted in mortality of 43.93% and 49.01% respectively. Concentrations 0.0625% and 0.25% of Pyriproxyfen and Buprofezin caused 24.63% and 31.46% mortality respectively at PAI of 3 days. Pyriproxyfen and Buprofezinat 0.03125%, 0.0125%concentrations caused 7.08% and 12.7% mortality respectively of P. solenopsis at PAI of 3 days. It is concluded that Buprofezin remained more toxic at all concentrations as compared with Pyriproxyfen. This information is very useful when formulating management strategy of CMB in future.
