Seasonal incidence of major insect pests of chilli and its correlation with weather parameters

The infestation of thrips, scirtothrips dorsalis Hood was initiated in the fourth week of July (30^th meteorological week) and remained continue up to first week of December (48^th SMW) during 2019–20. The data on correlation between weather parameters and thrips population was positively non significant correlation with rainfall and minimum temperature and negatively non significant with maximum temperature. The whitefly, bemisia tabaci Genn. was initiated in the fourth week of July (30^th SMW) and remained continue up to first week of December (48^th SMW) during 2019–20. The population increased gradually and touched its peak in fourth week of September (39^th SMW). The mite population persist throughout the crop season from first week of August (31^st SMW) and was continue up to first week of December (48^th meteorological week). The data on correlation and mite population was negative and non significant with rainfall, maximum temperature, minimum temperature. However, fruit borer, H. armigera appeared in the second week of September (36^th meteorological week) and remained continue up to first week of December (48^th SMW) during 2019–20. The data on correlation was negatively and non significant with rainfall, maximum temperature, evening RH. Whereas minimum temperature, evaporation and fruit borer population was negative and significant correlation.
