| Abstract | ||
| This study included laboratory ovulation of the effect of alcoholic(ethanol) extract of Teucrium polium, Peganum harmala,Thymus vulgaris and Physalis angulata. It was values LC50 (102.5,101.0,78.0 and 53.0 ppm) and LC90(130.0,128.0,136.0 and 80.0 ppm) for Teucrium polium,Peganum harmala,Thymus vulgaris and Physalis angulata respectively at 24 hrs. of exposure time. It was found that extract the Physalis angulata were more effective as larvicides at 24 hrs. exposure time with LC50: 53.0 ppm for On the other side, the LC90 for the previous plants at the same exposure time were 80.0 pmm. Also, the sub-larvicidal effect of the studed plant extracts at LC25 had been illustrated through histopathological effect on midgut. These effects were respectively by alimentary tract curling as body reflex, separation of epithelial columnar cell layer and separation of external muscular mucosa. Erosion of the Peritrophic membrane causing microvilli disappearing. | ||
