- Abstract
The aim of this research studied effect of plant leaves Powder of Eucalyptus camaldulensis, Laurus nobilis, Platycerium bifurcatum and Adhatoda vasica on larvae mortality of T. granarium insect of ages (initial, intermediate, advanced) in the laboratory were used tow doses of 0.025 and 0.050g/kg respectively, the results of four powders indicated the efficacy of the eucalyptus leaves powder was the most influential compare to the other three powders, the results showed that the initial age was the most sensitive to the Eucalyptus powder in 0.025 and 0.050g/kg doses respectively, mortality rate was 70.0 and 80.0%, respectively after 50 days and the advanced ages were the least sensitive at the rate of mortality 20.0 and 43.33%, respectively at time (40 and 30) day, respectively. The leaves powder of the Adhatoda vasica was the least affected between the other three powders were the initial age most sensitive. In 0.025 and 0.050g/kg doses, respectively and the mortality rates were after 50 days (30.0 and 46.66%) respectively. The advanced ages were the least sensitive and in 0.025 and 0.050g/kg doses and were recorded rates of mortality (13.33 and 23.33%), respectively after 30 days. The result shows that the mortality rates are increased by increasing the exposure time of the treatments with the powder in 0.025 and 0.050g/kg doses.
