The study deals with the effect of leaves powders of Nicotiana tabacum ,Nerium oleander , Zizphusspina-christi , Vitex agnus-castus, Lantana camara , Myrtus communis , Clerodendron inerum and Eucalptus globules on the mortality reduction in F1progeny and repellency of leaves powders on the red flour beetle . This results showed that when we mixed the leaves powders with crushed wheat grains in amounts of 4, 2,1, and 0.5 % weight by weight , the mortalities increased with increasing mount .The leaves powders of N. tabacum ,Z. christi and C. inerium was the best effected the mortality of the adults after 7 days it 97.5 ,71.77 , 68.33% respectively . The losses of percentage rate in the weight grains was revesaly proprotioed with mount of powder was the best mount 4 % reduced in the weight and also mixed leaves powder with0.92 % grains through 30 days reached food reducing F1 progeny , the best effected was L .camara it reached 95.12 % and producted rate reached 1.46% . The results showed that leaves powder of M communis was the best effected of response index reached - 0.1at all amounts 4 % and 2 % after 24 hours . The result showed was not effected the plants powdered of leaves in the percentag of germination of wheat grains treatment .
