Abstract :
The experiment was conducted in the Bio-Control Research laboratory, Department of Entomology, Faculty of crop Protection, Sindh Agriculture University, Tandojam in 2015. Age specific parasitism by Dirhinus gifardii on the pupae of Bacterocera zonata (saunders) was determined at 26±2 ºC and 65±5% RH. For this purpose 24, 48, 72 and 96 hours mature pupae of B. zonata were given to the adult of D. giffardii in cages by maintaining CRD with replication. The result showed that maximum parasitism and shortest emergence time was recorded as (53.33 %) within 10 days on 48 hours mature pupae. The same parasitism percentage (53.33%) was also recorded on 72 hours mature pupae but emergence time was prolonged to 12 days. Minimum parasitism percentage was recorded on 24 hours mature pupae followed by 96 hours. The female and male ratio varied significantly, it was recorded as 1:3, 1:9, 1:7 and 1:1.50 on 24, 48, 72 and 96 hours mature pupae, respectively. It is concluded that for culture development of D. giffardii 48 hours mature pupae should be utilized for better parasitism %, emergence and male female ratio.
