Abstract

The investigation was carried out at the Instructional Farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University (N.A.U.), Navsari, Gujarat, India during 2021-2022. The leaf webber, leafhopper, fruit fly, shoot borer, and thrips were found abundant, whereas the mealybug and stone weevils were very less. The leaf webber population exhibited a significant negative correlation with minimum temperature (r= -0.488*) and evaporation (r=-0.483*). The leafhopper population had a highly significant positive correlation with wind velocity (r= 0.577**) and rainfall (r= 0.823**) and a significant negative correlation with minimum temperature (r=-0.495*) and morning relative humidity (r= -0.414*). Fruit fly population exhibited a highly significant positive correlation with minimum temperature (r= 0.761**), wind velocity (r= 0.646**), and evaporation (r= 0.524**). There was a significant negative correlation of shoot borer population with minimum temperature (r= -0.804**), evening relative humidity (r= -0.467*), and wind velocity (r= -0.437*). Thrips population had a highly significant negative correlation with minimum temperature (r= -0.690**), evening relative humidity (r= -0.879**), wind velocity (r= -0.567**), and rainfall (r= - 0.541**) and a significant positive correlation with sunshine hours (r= 0.684**) and maximum temperature (r= 0.438*). Among natural enemies, ants, mantids, spiders, and chrysopa were found in the orchard and none of the parasitoids were reported.
