Use some plant oils, and organic nicotinic pesticides and bio-bacterial formulation (Thurcide) and its integration in control corn stem borer Sesamia cretica Led. (Lepidoptera:Phalaenidae) on maiz .

The results of evaluation of plant oils (neem oil, colocynth oil and castor oil) Actara, crusier bactericide and B. thuringiensis var kurstaki showed their compatibility with the phases of the field insect after three months of treatment where one (neem oil+ bacteria B. thuringiesis + crusier) of these treatments proved its success with less ratios of infection in the plants of Sesamia cretica Led reached 8.89%. The treatments with (colocynth oil+ bacteria B. thuringiesis + crusier) and (watering Actara + crusier) achieved a ratio of infection reached 13.22%, and 23.33% respectively comparing with the control treatment where the ratio of infection reached 94.50%. 
The less ratios of infection of corncobs in treatments (crusier + spraying Actara), (crusier + watering Acvtara), (neem oil + thurcide + crusier), and (castor oil + thurcide + crusier) reached 14.85%, 19.80%, 19.60%, and 19.90% respectively. These ratios have not differed incorporeally comparing with control treatment where the infection reached 54.61%. 
The results showed that all the treatments have increased the weight of the one corncob in comparison with the control treatment. The high weight of one corncob achieved in the treatments (castor oil + thurcide + crusier) and (neem oil + thurcide + crusier) which reached 134.4 g. and 133.13 g. respectively. The treatment (watering Actara + crusier) where the weight of the one corncob reached 129.52 g. in comparing with the control treatment where the weight of one corncob reached 96.04 g.
