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.
