| Abstract: | The silverleaf whitefly is one of the most important pests found commonly in Iran and in the world. The development of alternative methods instead of chemical applications is necessary in pest management for human health and environment protection. The objective of this research was to assess the effects of extracts of two medicinal plant species: Calotropis procera and Allium sativum, and a formulation containing azadirachtin on fecundity and fertility of the silverleaf whitefly, grown on greenhouse tomato plants. The effects were compared to that of pymetrozine, a synthetic insecticide. According to the results, there was a significant difference among treatments for all reproductive parameters. Gross fecundity rates for pesticides control, herbal extract control, C. procera extract, A. sativum extract, azadirachtin and pymetrozine were 184.75, 146.72, 80.11, 82.18, 63.06 and 55.96 eggs, respectively. These herbal extracts were effective against this pest and they can be the suitable choices for replacing these chemical insecticides. |
