abstract
We tested the efficacy of eight different insecticides viz., acetamiprid, imidacloprid, profenofos, methidathion, bifenthrin, carbosulfan, buprofezin and spirotetramat against the adult female mango mealybug Drosicha mangiferae in the laboratory using leaf-dip bioassay method. The insects were collected from citrus orchard of Citrus Research Institute, Sargodha and were tested on different insecticide doses in the Entomology laboratory of Citrus Research Institute, Sargodha, Punjab, Pakistan, during the year 2017 in the month of April. The mortality data was analyzed by split plot design under CRD using statistix 8.1 version software. Results indicated that methidathion (T4) produced significantly higher mortality of 73.57% seven days after treatment while mortality due to bifenthrin (T5) was 59.996% four days after treatment but it decreased to 20% seven days after treatment. Profenofos (T3) produced higher mortality (58.07%) seven days after treatment but it was significantly less as compared to methidathion (T4). Carbosulfan (T6) showed good results four days after treatment with 59.81% mortality but mortality was decreased to 45.664% seven days after treatment. The order of effectiveness of insecticides is as: methidathion > profenofos > carbosulfan > bifenthrin. The insecticides, acetamiprid, imidacloprid, buprofezin and spirotetramat were found ineffective for the control of adult female mango mealybug. The judicious use of the insecticides methidathion, profenofos and carbosulfan is recommended to the citrus growers to control this important pest.
