  abstract = {{T}he morphology of the female reproductive system of pupal and adult stages of {M}icroplitis rufiventris and the ultrastructure of the ovaries are described and illustrated. {T}wo morphologically distinct types of particles of nuclear origin, i.e., polydnavirus ({PDV}) and a virus-like filamentous particle ({VLFP}) were detected in the ovarian calyx fluid of the female wasp. {I}t is likely that these particles are injected into the host during oviposition. {PDV} initiated replication in the calyx of mid-aged pupae and in pharate adults and were present throughout adult life. {VLFP} were only seen in the calyx fluid of newly emerged adults, and therefore observed after the {PDV}. {F}eulgen and methyl-green pyronin staining revealed the presence of {DNA} in both types of particles. {T}he effects of injection of {S}podoptera littoralis larvae with a combination of parasitoid viruses and venom of {M}. rufiventris females ({C}x{FV}) were investigated and the results were compared with two control groups, i.e., larvae injected with {P}ringle's saline ({PS}) and naturally parasitized larvae. {C}x{FV}-larvae showed significant declines ({P} < 0.05) in food consumption, weight of ejected faeces and weight gain when compared with {PS}-larvae. {H}owever, naturally parasitized larvae (parasitoid egg+{C}x{FV}+ovarian protein) displayed a high significance score ({P} < 0.01) in comparison with those of {PS}-larvae. {T}he approximate digestibility ({AD}) values of {S}. littoralis larvae were positively affected as early as day 2 post-treatment by either injection of {C}x{FV} or parasitization. {H}owever, a reduction in {AD} was observed in both {PS}- and {C}x{FV}-larvae on day 3-7 in comparison with naturally parasitized larvae. {O}ther indices of food utilization were unchanged in {C}x{FV}-larvae when compared to saline treated or parasitized controls.
