RESUMO
The insecticidal activity of Zingiber officinale against the larval maturation and adult emergency of Anopheles pharoensis and Musca domestica 3rd stage was evaluated under controlled laboratory conditions. At A. pharoensis concentrations of 100%, 70%, 50%, 25%, 5%, 2%, 1%, 0.9%, 0.7%, 0.5% & 0.3% showed 100% larval mortality rate. 0.2% & 0.1% caused mortality of 66.7% respectively. On the other hand, the fecundity of emerged adults was zero% and 50%. In M. domestica the concentrations from 25%- 100% completely killed the larvae. 5%, 2% & 1% caused mortality percent of 66.6, 44.4 & 33.3 respectively. Less concentration of Z. officinale was not tried. The fecundity of the emerged adults was 66.7%, 25% & 16.7%. On the other hand, only one control larvae died and the nine emerged adults were fertile in the two cases. So, Z. officinale not only has a larvicidal action against M. domestica and A. pharoensis larvae but also affected the adult fecundity.

The insecticidal activity of Cinnamomum zeylanicum against the larval maturation and adult emergency of Anopheles pharoensis and Musca domestica 3rd stage was evaluated under controlled laboratory conditions. A. pharoensis with concentrations (conc.) of 100%, 70%, 50%, 25%, 5%, 2%, 1%, 0.9%, 0.7% & 0.5% showed 100% larval mortality. Conc. of 0.3%, 0.2% & 0.1% caused mortality of 77.8%, 44.4% & 33.3% respectively. The fecundity of emerged adults was 0%, 60% & 50%. In M. domestica the conc. from 50%-100% completely killed the larvae. Conc. of 25%, 5%, 2% & 1% caused mortality of 88.9%, 55.6%, 33.3% & 22.2% respectively. Less conc. of C. zeylanicum was not tested. The fecundity of the emerged adults was 0%, 66.7%, 66.7% & 83.3%. Only one control larva died and the nine emerged adults were fertile in the two cases.

The insecticidal activity of Trigonella foenum-graecunm (fenugreek) against the larval maturation and adult emergency of An. pharoensis 3rd stage was evaluated under controlled laboratory conditions. Concentrations of 100%, 70%, 50%, 25%, 5%, 2%, 1%, 0.9%, 0.7%, 0.5% & 0.3% showed 100% larval mortality rate. 0.2% & 0.1% caused mortality of 88.9% & 66.7% respectively. On the other hand, the fecundity of emerged adults was zero % and 33.3%. However, one control larvae died and the nine emerged adults were fertile. So, it was recommended to be use in controlling larvae of An. pharoensis.

The insecticidal efficacy of Trigonella foenum-graecum (fenugreek) on the 3rd stage larvae of Musca domestica and adult fecundity was evaluated under controlled laboratory conditions. The concentrations from 25% to 100% completely killed the larvae. 5%, 2% and 1% caused mortality percent of 44.4, 33.3 and 22.2 respectively. Less concentration of fenugreek was not tried. On the other hand, the fecundity of the emerged adults was 20%, Zero% and 28.6%. On the other hand, only one control larva died and the nine emerged adults were fertile. So, fenugreek at low concentration not only has a larvicidal action against house fly larvae but also affected the adult fecundity.

The insecticidal activity of Eucalyptus globulus oil (Camphor oil) against the larval maturation and adult emergency of the house-fly, Musca domestica 3rd stage was evaluated under controlled laboratory conditions. Concentrations of 100%, 70%, 50% 25%, 5%, 2%, 1%, 0.9 % and 0.7% showed 100% larval mortality rate. At concentrations of 0.5%, 0.3%, 0.2% and 0.1% the larval mortality rate was 90%. On the other hand, the developed pupae did not emerge to adults. Eucalyptus globulus oil is safe, cheap and widely used in Medicine. So, it is recommended to be use in controlling larvae of M. domestica.
