Melia azedarach extract were applied by feeding the adult female flies on diets mixed with the extracts at different doses. The concentrations of Melia azedarach utilized were 1.8, 2.4 and 3.6%. The gonotrophic cycles of length of 90, 753, 67.6 and 84, 72, 68 hours were obtained after feeding at age 24 hours with diet mixed with doses of 1.8, 2.4 and 3.6% fruit extract; respectively. 98 & 96 hours were the length of gonotrophic cycle in the control groups. The length of 86.7, 72.3, 57.3 and 89.3, 75, 61 hours were obtained after feeding adults at age 48 hours with diets mixed with different doses of fruit extract of the same plant 97.3 and 98.7 hours were the length of the control groups. Proportions of the egg hatching reached 69, 55.3, 49 and 72.9, 64.2, 52 in groups of eggs obtained from 24 hours adults feeding with diets mixed with doses of 1.8, 2.4 and 3.6% fruit extract; respectively. Also 68.7, 53.3,48 5 and 81 2, 70, 56.3 were the proportions of egg hatching obtained from groups at age 48 hours after feeding with diets mixed with the same doses. 85, 77.6, 62.2 and 92.6, 88.9, 84.9 were the proportions of the egg hatching obtained from groups feeding with diets mixed with doses of 1.8, 2.4 and 3.6% fruit extract of Melia azedarach; respectively. The pupae showed larval-pupal intermediates which failed to complete the pupal period and died after emerging from the third larval instar. DOI10.14302/issn.2637-6075.jpae-19-2586 The house fly Musca vicinais one of the common species found in human habitat in tropical and subtropical regions. It has gained importance as a serious public health hazard. Serious world problems in public health have arisen as insects can develop resistance against insecticides 1. The discovery of Melia azedarach as an insecticide of an entirely new type created quite a stir among entomologists interested in the practical uses of insect researches 2. It was found of great value to study the effect of crude extracts of fruits of Zanzalacht on Musca vicinawith the aim of investigating the effect of the Melia azedarach extract on the development capacities of the insect. The experiments stressed on the potential these plants have as effective and economic insecticides. Jatwani and Srivastava 3; Schmutterer 4 reported that the common species is Melia azedarach L as it contains six tetera-nortriterpenoids. Chiu 5 mentioned that the evaluation of the petroleum ether extracts of the seed kernels of Melia azedarach in the laboratory showed their potential as antifeedants for the control of the nymphs of Nilaparvatalegens.
