Study On The Control Of Banana Pest Odoiporous Longicollis Under Different Conditions By Using Different Insecticides

The commercial yield of banana is mainly affected by Odoiporous longicollis and Cosmopolites sordidus in Bihar during fruiting season and it is limiting the qualitative and quantitative aspect of banana crop. The two years data on efficacy of different insecticides and pesticides against infestation control of Odoiporous longicollis revealed that the soil application of Carbofuran (1kg/ha), Phorate (1kg/ha) and Quinalphos (1kg/ha) and foliar spray of Carbofuran (0.5kg/ha), Phorate (0.5kg/ha), Quinalphos (0.5kg/ha) have been found more effective in respect of damage control of pest infestation on banana crop. The present study indicates that all the said insecticides used as soil and foliar combination aginst the pest Odoiporous longicollis were significantly effective and superior to the control in preventing the damage of banana crop. The increased crop yield dozen/hectare was 27910 when using Carbofuran, 23820 when using Phorate and 20365 when using Quinalphos in the year 2016.
