Minor problems are leaf and fruit spot caused by Cercospora, Gloeosporium and Pestalotia sp.; also foliar damage by whitefly, thrips, mealybugs and scale insects; and defoliation by Euproctis spp. and Archyophora dentula. Termites may infest the trunk. In India, paper or plastic bags or other covers may be put over the fruits to protect them from borers, birds, bats and squirrels. 1
Root knot nematode, Meloidogyne incognita, has been reported to be a serious pest.



Leaf-Footed Plant Bug

Leptoglossus zonatus

These pests can measure up to two inches long and can fly. This pest bores holes into the ripening pomegranate fruits. The fruits get brown spoiled spots on them and eventually fall to the ground in a pile of rotting fruit.
The adult western leaffooted bugs are 19–21 mm long, dark brown, with flattened leaf-like expansions on the hind tibia. The adult is distinguished from the other Leptoglossus spp. by having a whitish zigzag band across the corium and two pale yellow spots on the anterior pronotum.
Leptoglossus zonatus (Dallas) is widely known as the western leaffooted bug, but this is not an approved common name. Leptoglossus zonatus is a prevalent polyphagous minor pest of various field, vegetable and fruit crops in the Gulf Coast region of the United States. It has become a key pest in citrus, especially of satsuma mandarin (Citrus unshiu Mar.). It is also considered an important emerging pest on a wide range of crops including corn, cotton, eggplant, peach, pecan, pomegranate, tomato and watermelon in the United States (Xiao and Fadamiro 2011). 2

Pomegranate Fruit Borer

Virachola isocrates

The pomegranate fruit borer or pomegranate butterfly are pests common in Asia, especially India and Sri Lanka. Adult males have glossy blue wings, females have brownish violet with an orange circular spot on the forewing.
PFB larvae bore into the pomegranate fruits soon after hatching from eggs laid on flowers or young fruit. Once inside the fruit, the flat larvae (approx 2cm length) feed on the flesh and seeds. Infested fruit will often have PFB feces near the bore holes of entry. The holes ultimately expose the rest of the fruit to disease, and typically rot off the tree. 2
