Abstract
The cowpea aphid, Aphis craccivora Koch. is the most common species attacks leguminous crops in Egypt. Among the parasitoid species which attack A.craccivora on faba bean was the braconid parasitoid, Lysiphlebus faberum Marchall. Morphological and biological studies on the parasitoid species were conducted under the laboratory conditions, 200D and 70% R.H. Egg, larva, pupa and adult of the parasitoid were described. Biological studies included duration of immature stages, emergence process of the parasitoid adult, mating behavior, egg-laying process, adult longevity and sex ratio. Duration Of Liabarum immature stages averaged 0.4 t 0.03. 5.2 t 0.2 and 4.1 t 0.1 days under laboratory conditions for the incubation period, larval and pupal periods, respectively. Adult longevity lasted 1.9 ± 0.1 and 4.1 t0.2 days for male and female, respectively. Sex ratio was estimated as 1:2.8 Cifq_ under the laboratory conditions.
