Abstract

Studies were carried out to asses.. the population density of mealybug on ber
and economic losses sustained. On an average there were 80.6 colonies per
plant, each colony having 17.8 Individuals. Similarly 15.4 egg masses covered
with white waxy mealy matter were observed per plant, each egg mass containing
90.7 orange coloured oval shaped eggs. Based on the market price of Infested
and healthy fruits, there was a net monetary loss of Rs. 25,800/ha accounting.
for 33.33 per cent loss due to mealybug Infntatlon.
