Effects of ethanol extracts of Datura stramonium, Solanum nigrum, Quercus infectoria and Xanthiumstrumarium on the mortality, egg hatching, reduction in F1 progeny and repellents on the red flour beetle wereinvestigated. The results showed that cypermethrin had the best effect on the mortality of adults (100%) on allconcentrations, whereas the fruits of Datura stramonium and Xanthium strumarium had a mortality rate of100% in 2% and 4% concentrations. Egg hatching was also delayed, and began after four days of treatment, inQuercus infectoria and Xanthium strumarium. Ethanol plant extracts of Datura stramonium caused 100%mortality of larvae at a concentration of 1% after eight days of treatment, followed by the alcohol extract ofSolanum nigrum with 97.43% mortality in 1% concentration. Mix of ethanol plant extract with food reduced F1progeny. Cypermethrin and Datura stramonium were given the best effect that reaches 17.06% and 18.11%respectively. Repellents percentage showed that ethanol extracts of Datura stramonium and Solanum nigrumshowed repellents of 91.87% and 91.45% in 4% concentration after 24 hours of treatment.
