abstract
The present study entitled, “To study the seasonal incidence of shoot and fruit borer, (Leucinodes orbonalis Guenee) on brinjal during Kharif season of 2016 in Trans Yamuna region of Allahabad” was undertaken at the Central Research Farm, SHUATS, Allahabad. The data so obtained through observation on various aspects were subjected to statistical analysis wherever necessary and the data was compiled. Results, thus obtained are presented aspect wise as the occurrence of Leucinodes orbonalis Guenee in Per cent shoot infestation was recorded in 2016 Kharif season was commenced from 34^rd standard week (August third week) on shoot with an average 3.85 % infestation. The borer population increased and gradually reached peak level of 33.5% of larval population at 42nd standard week (October third week) and decline in the trend was noticed this may be due to fall in congenial weather parameters and the per cent fruit data showed that from 39th standard week (third week of September) on shoot with an average 4.6% infestation. The borer population increased and gradually reached peak level of 40.5% of larval population at 46th standard week (second week November). Thereafter, declined trend was observed due to fall of maximum and minimum temperatures as optimum weather condition are decreasing. It was observed that the maximum temperature favoured the multiplication of shoot and fruit borer whereas, decline of maximum and minimum temperature lead to decline of the shoot and fruit borer population.
