Abstract:
Okra, Abelmoschus esculentus (L.) Moench is an important vegetable crop in the tropics and subtropics, grown throughout the year. This crop is severely damaged by more than 30 pests among them shoot and fruit borer (Earias vittella) is major one. Climatic factors play vital role in multiplication and distribution of okra fruit and shoot borer (OSFB). Therefore, the experiment was conducted to study the effect of seasonal incidence and weather parameter impact on OSFB infestation. The incidence of shoot damage was observed maximum (23.50%) during the 34^th SMW and the infestation of fruits by E. vittella observed the peak level (36.80%) at 39^th SMW. The correlation analysis revealed that the negative and significant correlation between maximum temperature and shoot damage. Whereas, positive and significant correlation was observed between shoot damage with morning relative humidity and evening relative humidity. Among various weather parameters, minimum temperature and wind velocity shows negative and significant correlation with fruit damage.
