| Abstract | ||
| The study was conducted to evaluate the efficiency of the difference in the date of planting and soil treatment with Bioagent in control of mole cricket Gryllotalpa sp. on some summer crops and vegetables during season 2012. Results of the study dieated that the date for the cultivation of sunflower crop had considerable influence on infested plants with mole cricket , since the early planting lead to seed germination and development at good root system which was non-preferred to insect , The highest percentage losses at early planting reached 3.67% and the number of tunnels was 4 in the early planting while reached 32.57% and tunnels was 14 in late planting. The efficiency of commercial formulation of fungi bioagent showed that field soil treatment with Metarhizium anisopilae marked high protecting level for cowpea , cucumber , okra , melon and sunflower against mole cricket infestation and decreased the economic losses to 3.37%. Using Beauvaria bassiana formulation the percentage loss reached 19.01%, while treatment with Trichoderma harzianum was the least efficient with infestation level of 29.12% compared with the control treatment which had the percentage losses reached 62.71%. | ||
