Abstract

Highest population of flea beetle was recorded (7.16 flea beetles/plant) in 20th standard week. Population of flea beetle showed significant positive correlation with average temperature and non significant negative correlation with average relative humidity and weekly rainfall. Field evaluation of pesticides revealed that DDVP was found relatively more effective against flea beetle on brinjal (33.43% control), followed by avermectin (30.34% control) and neem (30–28% control).
