Subject(s): Online resources: In: Egyptian Journal of Biological Pest Control 2008.v.18(1)Summary: Interest of dry vegetables in particular the chickpea as protein food is very important. Considerable quantitative and qualitative losses, especially on the level of stocks are due primarily to the attacks of the insect pests, particularly the Chinese beetle, Callosobruchus chinensis L. Three plant species (Thymus vulgarus, Santolina clwmaecyparissus, and Anagyris foetida) extracts were tested for their biocide effect on the pest under controlled conditions (28° C and R.H. 75%). Effect of various amounts of the powders and oils of the extracts were studied on some biological parameters; fertility, longevity, fecundity and life cycle. Obtained results showed that oil and the powders of the tested three plants presented obviously bio-insecticidal effects. Concerning the essential oils, thyme acted as inhibiting substance or biocide achieving 100% mortality, followed by Santolina. Concerning the powders, Sallfolina showed an inhibiting effect on the individuals and laid eggs as fertility was very low compared to the other powders of Anagyris and of Thyme. Therefore, the tested plants could to be used as bio-insecticides for the control of the devastating C. clzinensis in the stored food products.
