Abstract : This paper reports the incidence of hopper (Amritodus atkinsoni) populations recorded in Tamil Nadu, India, from January to December 1999, on the mango cultivars Neelum, Bulgoa and Bangalora and its correlation with weather parameters. The hopper population was more in Neelum than the 2 other cultivars. Peak seasonal incidence was noticed in March-April, coinciding with the blossoming, which declined afterwards until December. An increase in the temperature during April-July, led to an increase in the hopper populations. From August onwards, the hopper population continuously decreased with the monsoon rains. Hopper Populations correlated positively with maximum temperature, but negatively with relative humidity and rain.
