The study was conducted on bio-ecology and management of mango
mealybug Drosicha mangiferae (Green) in mango orchards of Punjab
Pakistan. It was found that the Chaunsa' cultivar was the most
susceptible to mango mealybug followed by 'Fajri', 'Langra' and
'Black Chaunsa, whereas 'Dusehri' was resistant. Irrigation was the
major source of flare up of the pest as viewed by the majority of
the respondents. The practices like hoeing, ploughing, irrigation,
removal of weeds, grease bands and insecticides were adapted by the
respondents with variable results. With chemical analysis maximum
carbohydrates contents were observed in the cultivar 'Chaunsa'
(susceptible to the pest), whereas minimum carbohydrates contents
were observed in the cultivar 'Tukhmi' resistant to the pest. The
maximum decrease in number of fruits was recorded 11 percent on
cultivar 'Anwar Ratul', whereas 'Langra' cultivar showed minimum
decrease in number of fruits i.e., 3 percent over untreated trees.
