Bionomics of Bactrocera dorsalis (Diptera: Tephritidae) – an important pest of Mango (Mangifera indica) in Jammu (J & K)
Abstract :Mango
(Mangifera indica L.) is known as
“king of fruits”. Several insects are known to cause significant damage to
mango and affect its productivity. One of them is Bactrocera dorsalis which is an important pest of mango in India. Keeping in view the medical, economical and dietary
importance of mango and damage done to it by different insect pests, work was
done to study the biology of this pest
which causes huge damage during (May to September). Adults are strong
fliers, eggs are laid in the soft skin of ripening fruits. On hatching, the
maggots bore into the fruit further and feed on soft pulp. The infested fruits
bear depressions with dark green punctures and when cut open wriggling maggots
were seen inside. Later, the affected fruits get malformed and in conjugation
with bacterial activity, fruits rot and ultimately fall down. Maggots emerge
from these fruits and pupate in the soil
