Testing genetic build response of Egyptian laboratory strain of Cryptolaemus montrouzieri mulsant (Coleoptera: Coccinellidae) at random allogamy and inbreeding mating techniques [electronic resource]

Effect of two mating techniques (random allogamy and inbreeding (brother-sister) on some effective morphobiological parameters of the Egyptian laboratory strain of the predator, eryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae), when reared on the citrus mealy bug, Planococcus citri (Risso) at the Lattakia Center for Rearing Natural Enemies, was studied. The predator's Egyptian strain was obtained from the Biological Control Mass-rearing Laboratory, Faculty of Agriculture, Cairo University, Giza, Egypt through personal communication. The study was carried out at 25±2 ac, 60±1O % RH and 16:8 h (L: D) for six generations. Morphobiological parameters of different generations and for both techniques were compared with the parent generation (PG). Obtained results showed that there were insignificant differences in all morphobiological parameters between PG and F6, using random allogamy mating. Morphobiological indicators of females were more affected by the mating technique and recorded significant decrease using inbreeding mating in F3. Female length response for inbreeding mating in F3 and F6 was -4.91 and -9.41 %, respectively, while it increased to -3.28 and 1.23%, using random allogamy. Fecundity, reproduction,
