Abstract:
The experiment was carried out during two consecutive years 2021-22 and 2022-23 at Regional Horticultural Research Station, Navsari Agricultural University, Navsari to study the population of shoot and fruit borer, Leucinodes orbonalis Guenee during Rabi season on brinjal. Number of L. orbonalis larvae per brinjal plant reached peak at 4th Std. week (2.1 larvae/plant) and (2.2 larvae/plant) i.e., last week of January during 2021-22 and 2022-23 respectively. The correlation matrix indicated a significant negative correlation with minimum temperature (r = -0.582) and evaporation (r = -0.518) and significant positive correlation with maximum temperature (r = 0.663), Av. temperature (r = 0.666) with shoot and fruit borer infestation during 2021-22. However, Min temperature (r = -0.498) was significantly negative correlation, and max temperature (r = 0.663) and Av. Temperature (r = 0.685) were significant positive correlation with brinjal shoot and fruit borer.
