| Abstract | ||
| The current study has been conduced to evaluate the effect of extracted crude terpens at the concentrations of 6,8% of seeds of Eucalyptus camaldulensison the 4th larval instar of the Callosobruchus maculates and the percentage of the cowpea seed germination. The Results showed that the terpens extract of the concentration of 8% increases the mortality rate of the fourth larval instar and it reach to 63.3%, and then decrease of to 26.6, 20% at concentration of 6%and for control treatment respectively The percentage of adult emergence reduces to 0% at the concentration of 8% compared with control treatment in which it reach to 66.6%. The extraction at bothconcentrations 6,8% does not affect the germination rate. | ||
