Biological study of the parasitoidCitrostichusphyllocnistoides Narayanan (Eulophidae:Hymenoptera)as one of local parasitoides on Phyllocnistis citrella Stainton (Gracillariidae:Lepidoptera)in Syrian cost

A laboratory study was conducted on the parasitoid Citrostichus phyllocnistoides Narayanan (Eulophidae : Hymenoptera)under average of temperature (18.12± 2.12 Cº) with Temperature range from 15-23Cº. The final results oflaboratory study indicated that parasitoid was passed four stages to complete life cycle. The average development time was: 3.7±0.9 days for eggs – 7.8±0.9 days for larvae,(the time required from the eggs to hatch and continued untilthelarvae enter the pupal stage 6-10 days) , and12.7±1.03 days for pupa (the time required from the beginning of pupation to emergence of adult 11-14 days). The parasitoid needs in average23.3±2.7 days to complete its life cycle. Male longevity 3.8±0.8 days , and female 4.2±0.9 days.
