Report of a parasitic wasp (Hymenoptera: Encyrtidae) parasitizing cotton mealybug (Hemiptera: Pseudococcidae) in Pakistan and use of PCR for estimating parasitism levels
A parasitic wasp, Aenasius bambawalei, was studied for its biological parameters and parasitism levels in the cotton mealybug (Phenacoccus solenopsis). Biological parameters including parasitism efficiency, time to pupation, time to eclosion and adult sex ratio were studied under lab
conditions. Parasitism levels in field collected mealybug were determined using PCR. Results showed an increase in parasitism over the study period, with higher parasitism levels in 2009 compared to the preceding 2 years.
