3 Pests More than 100 pests are known to attack grapes in India. Among them, thrips, mealybugs, stem borer, mites, bats and birds are considered to cause serious losses in various regions if adequate and timely preventive and curative measures are not taken. Yield losses as high as 80 % have been reported on grapes due to insect pests in India. Insects Insects take a heavy toll on the grape crop. A total of 132 insects are known to attack grapevines worldwide. Of these, only about ten species are considered to cause losses in various regions and different grape-growing states of India.
Severe thrips attacks cause necrosis in the leaves; the leaves dry up and drop off the vine, and adults as well as nymphs migrate to healthy leaves. 14 The punctures of nymphs and adults produce a toxic reaction that retards the development of tender shoots. In heavy infestations, shoots may be severely stunted. Thrips also attack blossoms and developing berries and cause a certain amount of abortion during the flowering period (Bounier 1976). When eggs are laid in newly developed berries, a small dark scar, surrounded by a lightened area, develops (this is also called a halo spot).
