Abstract

The current study was investegated at the Department of Plant Protection, The University of Agriculture Peshawar during the year 2020 in a Randomized Complete Block Design (RCBD) with three replication. Aim of the study was to find out dose response biassay of acetamiprid towards pink hibiscus mealybugs, (Maconellicoccus hirsutus) under laboratory condition. Three different concentrations 0.1%, 0.2% and 0.3% of acetamiprid was used was used in this experient against the M. hirsutus using dip and spray method. In leaf dip method experiment, the results showed that maximum mortality (86.67%) was recorded at 0.3%, this was followed by 2 % with where 70% mortality was recorded after 72 hours. While   at 0.1 % (50%) mortality was recorded. Similarly, while in case of spray maximum mortality of pink hibiscus mealybugs (78.57%) was recorded at dose rate 0.3% of acetamiprid followed by dose rate of 0.2 with (71.43%) while minimum mortality (50%) was observed at dose rate of 0.5%. The study revealed that 0.3% concentration of Acetamiprid was found effective against in both the dip and spray methods and can be used against in M. Hirsutus IPM program.
