The Effectiveness of Some Plant Extracts on the Viability of the First Larval Instar and Adults of House Flies

Abstract

The current study included an examination the effect of some plant extracts such as lemon peel extract, mint leaf, and tobacco on the life of the first instar larvae and adults of Musca domestica   in terms of knowing the percentages of killing larvae  and adult of the insect treated with the plant extract.The results of the study showed that the extract of lemon peels has the highest effect on the life of the insect compared with other extracts and by different concentrations and duration of treatment, as it gave the highest killing rate of larva 100%  at the concentration of 2000 ppm and the killing rate of 100% at the concentration of 1500 ppm and the lowest killing rate of 22.33, 27.77% at the concentration 100ppm during 24, 48 hours of treatment, respectively, while mint leaves gave the highest percentage of killing 90, 93.33% at the concentration of 2000 ppm, and the lowest percentage of killing is 15.55, 20% at the concentration of 100 ppm, while the tobacco plant extract gave the highest percentage of killing amounted to 83.33 , 88.88% at a concentration of 2000ppm and the lowest percentage was 0, 10% at a concentration of 100ppm during 24 and 48 hours of treatment the first larval instar of the Musca domestica   respectively.                                                                                           

 The results of the study conducted a higher effect of plant extracts during treating adult of Musca domestica, the lemon peel extract gave the highest killing rate of 100% at a concentration of 2000ppm, while the percentage was 100% at a concentration of 1500ppm, and the extract gave the lowest killing rate of 33.33, 45.88% at a concentration of 100ppm, respectively. After 24, 48 hours of treatment of insect adults, the peppermint plant extract had the highest killing rate of 86.66, 100% at the concentration of 2000ppm, and the lowest killing rate of 26.66, 36.66% at the concentration of 100ppm, while the extract of the tobacco plant gave the highest killing rate of 80.22. 92.88% at a concentration of 2000ppm, and the lowest percentage of killing was 18.66, 33.55% at a concentration of 100ppm during treating the adult of Musca domestica respectively.
