Greenhouse whitefly (Trialeurodes vaporarium</em>) Westwood is one of the most important plant pests in Iran and the world. Due to the resistance of whiteflies to common insecticides and the harmful nature of these insecticides to the environment, new and safe compounds should be sought to combat this pest. Epile's new insecticide with a new combination while controlling this pest is also less dangerous for the environment Based on the Bioassay results, LC30 is considered a lethal concentration. The LC30 levels for the insecticides Epile, Abamecetin and Omidochloroprid were 1.31, 0.00448 and 0.00868 mg/lit. The results showed that the application of sub-lethal concentration of the treatments by spraying reduces the length of egg hatching period for the insecticides of Epile, Abacmetin and Omidchloroprid by 11.33, 5.45 and 4.53%, respectively, compared to the control and Epile is less than the length of the egg-related insecticide period. Also, Epile insecticide increased the length of  the larva period by 5.13% and the pupa period by 0.62% compared to the control. Also, the lifespan of adult insects was reduced by 38.64%, and in general, it reduces the lifespan of whitefly.

Hemiscorpius lepturus scorpion present in the southern provinces of the country, especially in Khoozestan stings a lot of people that results in long-standing dangerous side effects and sometimes even mortality. As the study of the effects of this scorpion venom on some laboratory animals can determine its mechanism of action and help us to cure people stung by scorpions, this study has been done to study the effects of Hemiscorpius lepturus venom on levels of WBC, RBC and hematocrit of rats.

An experimental study has been done on 51 rats of the same race with approximate age of 2-3 months, and weight of 200-250 grams. . All the hematological features including WBC (White Blood Cell), RBC (Red Blood Cell) and HT (Hematocrit) were measured prior to venom injection. The same procedures were followed after injection of 1 microlitre of venom. Results before and after injection have been analyzed by Wilcoxon Matched, Pairs signed and Ranks statistical tests.

The results of the study have shown that the venom caused changes in the levels of WBC, RBC and Hematocrit. The mean level of WBC at the start was 10234, whereas following the venom injection it reached to the level of 11757( P<0.0007). The mean number for RBC before the treatment was 7509130 and after injection, the number declined to 7065098( P<0.0001). The average amount of Hematocrit before and after injection was 40.087% and 39.0588 %, respectively (P<0.001).

Hemiscorpius lepturus venom has some effects on the levels of WBC, RBC and hematocrit of rats. The study of the hematological changes in humans can lead to better study of the effect of this venom and consequently suitable cure for the injured.
