Insecticidal, repellency and oviposition deterrent of hexane extracts of some Plants on Tribolium confusum (Col.: Tenebrionidae)

Tribolium confosum is one of the most important pests of stored products that can damage the quality and quantity of flour. Using the plant syntheses is one of the best methods to control of stored products pests especially that insecticides have many dangerous effects in environment and the amount of damage is high. The purpose of this research was to compare the efficiency of hexane extracts of some plants oviposition deterrent rate, larvicidal rate and repellency rate against T.confosum: Calotropis procera, Vinca minor, Zygophylum fabago and Delphinium persicum. The results showed that Z. fabago in 50% pure extract was the most effective extract by 60.69% larvicidal percent and V. minor was the least effective extract by 30.41% larvicidal percent. Z. fabago, D. persicum and C. procera were effective in repelling of pests. These extracts reduces to oviposition in comparing to control but there was no significant difference between the extracts oviposition deterrent in adults. As these exctacts have repellency, oviposition deterrent and insecticidal effects, can be used as a source to control this pest.
