| Abstract | ||
| Studies were conducted to investigate the combined effect of the bioinsecticide (Agreen) and the growth regulators Cascade (Flufenoxuron) and Insegar (Fenoxycar) with two chemical insecticides Diazinon and Cruizer) against the corn stalk borer Sesamia cretica Led. and on the egg parasitoid Telenomus busseolae Gahn. (Scelionidae hymenoptera). Result indicated that these insecticides can be mixed with each other and with the seed treatment insecticide Cruizer (Thiamethxan) to achieve a better control. No significant effect was observed on parasitism or on adult parasitoid emergence from treated corn borer eggs. However, the mixture of Cascade and Agreen reduced the parasitoid emergence percent to 73.7% compaired with 95.5% in the untreated eggs. No influence was observed on the behavior of female parasitoid emerging from treated eggs. Therefore the integration of this parasitoid with the tested insecticides can be recommended for the control of the corn stalk borer under field conditions. | ||
