Abstract
A series of laboratory experiments were conducted to determine the effect of Allium sativam and Myrtus communis extracts and their synergistic effect in control of the Tribolium castaneum (Herbst), The results of the experiment showed a significant effect between the type of extract and extraction method with water and alcohol extracts and concentrations of extracts In the rate of larvae stage killing of Tribolium castaneum, The concentration of 4 mg / ml was recorded In the extraction method (the extract of alcohol) of the plant Myrts communis highest kill rate in the larval stage of Tribalium castaneum was 33.333%, The concentration of 2 mg / ml was obtained by extracting the alcohol extract and a concentration of 3 mg / ml for Myrtus communis highest mortality rate in Tribolium castaneum was 20.0%. The results showed a significant effect on the synergistic effect of sunflower oil Between the type of extract and extraction method and concentrations of extracts In the adult mortality rate of the Tribolium castaneum the concentration of 3 mg / ml was recorded with the activated (synergistic) water extract of Myrts communis highest rate of killing in the adult stage of the insect was 83.8% .
