The accumulated effect of alcoholic leaves extract of huds plant(Mentha longifolia L.) and henna plant (Lawsonia inermis L.) in the life performance of immature stages of Musca domestica L. (Diptera: Muscidae)

Abstract

The aims of this study were to know the accumulated effects of alcoholic leaves extracts of henna and huds plant in some biological aspects of immature stage Musca domestica .four concentrations have been used, 500, 750, 1000 and 1250 mg L-1 for both two plant extracts and four replications for each concentration, their effect on life cycle ,growth stadium of immature stages (eggs, Larvae, and pupae), pupae weight .There was no significant effect for both extracts in egg incubation period, where it was 1.50 and 1.75 days at a concentration 1250 mg L-1. There was an increasing in duration of 1st,2nd ,and 3rd larvae phase ,whereas it reached 1.50, 2.75, and 5.75 days, and 1.75, 2.75 and 6.25 days respectively for huds and henna at a concentration 1250 ppm, when it compared with control which were 1, 2, 4.25 days for 1st, 2nd, 3rd larval respectively. The mortality increased with increasing of concentration, where the maximum egg mortality % was 20% and 22.50% in huds and henna extracts ,and in first larval phase (most effected) the mortality came to 26.26 % and 27.82% for both huds and henna extracts at aconcentration 1250 ppm respectively, and a reduction in pupae weight that reach 0.038gm and 0.036gm in huds and henna respectively, wheas it was 0.092 gm in control.
