Phyllotreta striolata, cruciferous crops, turnip, radish, cabbage, seasonal incidence, correlation, regression, temperature, relative humidity, rainfall, sunshine hours


This study is on the seasonal incidence of Phyllotreta striolata F. during 2015 and 2016, on turnip (Brassica rapa var. rapa), radish (Raphanus sativus) and cabbage (B. oleracea var. capitata). The incidence observed at weekly intervals was correlated with weather factors. The pest was first observed during 35th standard meteorological week (SMW), and in 2015, peak was observed on turnip (22.8 beetles/ plant) and radish (22.2 beetles/ plant) during the 40th SMW; during 2016, peak was (19.4 beetles/ plant on turnip; 22.2 beetles/ plant on radish) in the 39th SMW; and on cabbage, the peak incidence (4.8 beetles/ plant- 2015; 9.2 beetles/ plant- 2016) was during 38th SMW. The incidence showed a positive correlation with temperature and sunshine hours, and a negative correlation with relative humidity and rainfall.
