Evaluation activity of bacteria Bacillus thurengensis and different concentrations of plant extracts on adult of house fly Musca domestica

Abstract

This research included evaluating the efficacy of plant aqueous extracts for myrtle Myrtus communis, Nerium oleander, Eucalyptus spp. and Bacillus thuringiensis on adults of the house fly Musca domestica L. under laboratory conditions at a temperature of 2 ± 28°C and with a humidity of 50-70 %. it was found that the highest rate of laying eggs was in the extract of eucalyptus leaves, where the number of eggs laid was 60 eggs on average and at a concentration of 5%, while in the concentration of 10% the average egg was 55 eggs then In the extract of the leaves of the oleander was at a concentration of 10% at a rate of 50 eggs and in control treatments the number of eggs reached 80 eggs and the results showed the highest death rate for adults before laying eggs was in the extract of the eucalyptus leaves at a concentration of 15% where the death of 6 adults and the lowest percentage of death by 5% was recorded One adult death and the highest rate priest for eggs, with a concentration of 10%, reached 94%, and the highest percentage of larval mortality reached 68.12%, with a concentration of 10% in the transactions of extract of oleander leaves, and in it also the highest rate of exclusion is 31.93%. The third larval stage with a concentration of 5% with a ratio of 3.67 days and the highest incidence rate in the third larval stage with a concentration of 2.5% at a rate of 26.70% and the lowest incidence rate of 6.70% with a concentration of 2.5% and 5% and 7.5% in the first and second stages respectively and the lowest dawning rate was recorded in the larval phase the first with a concentration of 2.5% at 16.66% and the highest deformation rate in the third larval stage with a concentration of 7.5% at 66.66%. As for its effect on the number of eggs was a rate of zero% of all concentrations (2.5%, 5% and 7.5%) compared to 80 control egg either its effect on the longevity of the adult was the highest rate of longevity amounting to a concentration of 7.5% by 5.33 day..
