It damages stem and branches of grown up trees by eating bark and making tunnel into them. This insect is the problem of neglected orchards.Pest can be controlled by spraying 0.03 % Endrin or injecting kerosene oil or petrol in the holes and plugging them with cotton or wet soil during September-October and February-March.

Bark eating caterpillar (lnderbela tetraonis)

The young caterpillars bore into the apical portion of the shoot during rainy season and make tunnel. Due to this, damaged region bulges out abruptly into a gall which provides space for movement of the caterpillar. Due to this, apical growth is checked, side shoots develop below the gall and subsequent growth in following season is badly hampered.

This can be controlled by pruning the affected parts and spraying with 2 % Parathion. Prophylactic spray of systemic insecticide like Roger 0.03 % is also suggested.

Whiteflies are tiny, sap-sucking insects that are frequently abundant in vegetable and ornamental plantings. They excrete sticky honeydew and cause yellowing or death of leaves. Outbreaks often occur when the natural biological control is disrupted. Management is difficult.

White Fly

This caterpillar roll& the leaf and feeds inside it resulting in reduced photosynthetic capacity of leaves and subsequent leaf shedding. It can be controlled by spraying 0.08 % Malathion

Aphids are small, soft-bodied insects with long slender mouthparts that they use to pierce stems, leaves, and other tender plant parts and suck out fluids. Almost every plant has one or more aphid species that occasionally feed on it. Many aphid species are difficult to distinguish from one another; however, management of most aphid species is similar
