Cinnamon

Cinnamon butterfly

Symptoms of damage

Larvae feed on tender and slightly mature leaves

In severe cases of infestation, the entire plant is defoliated and only midribs of leaves with portions of veins are left.

Identification of pest

Eggs: Pale yellow in colour.

Larva

Undergoes various changes of colour pattern.

Grown up caterpillar are shaded with deep yellow on sides.

Adult

The upper side of adult is rich velvety brown.

Forewing: The upper side has marginal series of spots and terminal series of spots between the veins.

Hind Wing: The upper side bears a series of long arrow shaped streaks, yellow and white spots between the veins.

Management

Spraying quinalphos 0.05% on tender and partly mature leaves

Leaf miners

Symptoms of damage

Larvae feed on the tissues between the upper and lower epidermis of tender leaves resulting in linear mines that end in 'blister' like patches.

The infested leaves become crinkled and the mined areas dry up leading to the formation of large holes on the leaves.

Identification of pest

The larvae are pale gray initially and later become pink.

The adult is a minute silvery gray moth.

Management

Spraying quinalphos 0.05% during emergence of new flushes is effective in preventing the pest infestation.

Many other leaf feeding caterpillars and beetles also occur sporadically on cinnamon feeding on tender flushes. Application of quinalphos 0.05% would keep them under check.
