Seasonal Incidence of Head Borer, Hellula undalis Fabricius and Coccinellid Predators in Cabbage and Their Correlation with Weather Parameters

The investigation was conducted to study the seasonal incidence of cabbage head borer, Hellula undalis Fabricius at Regional Horticultural Research Station Farm, ASPEE College Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat, India during 2021-22. H. on commenced from 48th Standard Meteorological Week (SMW) with its peak in second SMW then decreased gradually until 10th SMW, i.e., end crop growth period. larval population had highly significant negative correlation maximum minimum temperature evaporation. There 88.78 per cent association weather parameters. Only coccinellid predators viz., Coccinella transversalis Cheilomenes sexmaculata Fabricius, were noticed ecosystem period none parasitoids reported. initial occurrence coccinellids noted increased successive weekly counts reached thereafter, declined SMW. beetles. variation abundance contributed by abiotic factors 85.30 cent.
