• Crop: ChilliScientific name:Capsicum annumFamily: Solanaceae 

Page 4: Chilli pepper insects  A Lecture By Allah Dad Khan Provincial Coordinator IPM MINFAL Islamabad

Chilli thrips: Scirtothrips dorsalisSymptoms of damage:

• The infested leaves develop crinkles and curl upwards

• Elongated petiole• Buds become brittle and 

drop down• Early stage, infestation leads 

to stunted growth and flower production, fruit set are arrested

ThripsIdentification of pest:

• Nymph: Are small, linear, easily fragile abdomen with straw yellow colour

• Adult: Fringed wings

Green peach aphid: Myzus persicae

Symptoms•  of damage:• The infested plants turn 

pale with sticky appearance• The leaves curled and 

crinkled• Honeydew excrete - 

development of sooty mould

• Stunted growth of the plant

Page 7: Chilli pepper insects  A Lecture By Allah Dad Khan Provincial Coordinator IPM MINFAL Islamabad

Identification of pest:

• Nymphs: Initially are greenish, but soon turn yellowish

• Adults: yellowish green in colour

•

Tobacco cutworm: Spodoptera lituraSymptoms of damage:

• Newly hatched larvae scrap the green matter in the leaf

• Affected leaf looks like a papery white structure

• Later instar larvae feed by making small holes

• In severe infestations they feed voraciously on the entire lamina and petiole

Page 9: Chilli pepper insects  A Lecture By Allah Dad Khan Provincial Coordinator IPM MINFAL Islamabad

Identification of pest:

• Egg: Eggs are golden yellow, laid in masses and covered by silky hairs.

• Larva: Are seen in groups, young caterpillars are light green with black head or black spots

• Adult: Are brown in colour. Forewings are brown colour with wavy white markings, hind wings are white colour with a brown patch along the margin.

Gram caterpillar: Helicoverpa armigera

Symptoms•  of damage:• Early instar feeds on foliage• Grown up larvae mainly 

bore into the fruits.

Identification of pest:

• Eggs: Are spherical in shape and creamy white in colour, laid singly

• Larva: Shows colour variation from greenish to brown

• Pupa: Brown in colour, occurs in soil, leaf, pod and crop debris

• Adult: Female is brownish yellow stout moth, Male is light greenish in colour with “V” shaped markings.

Yellow mite or muranai mite: Polyphagotarsonemus latus

Symptoms •  of damage:Downward 

curling and crinkling of leaves

• Leaves with elongated petiole

• Stunted growth

Page 13: Chilli pepper insects  A Lecture By Allah Dad Khan Provincial Coordinator IPM MINFAL Islamabad

Identification of pest:

• Egg: Oval shaped eggs and white in colour

• Nymphs: white in colour• Adult: Large, oval and broad 

and yellowish in colour•

Beet armywormSpodoptera exigua

Symptoms

• Singular, or closely grouped circular to irregularly shaped holes in foliage; heavy feeding by young larvae leads to skeletonized leaves; shallow, dry wounds on fruit; egg clusters of 50-150 eggs may be present on the leaves; egg clusters are covered in a whitish scale which gives the cluster a cottony or fuzzy appearance; young larvae are pale green to yellow in color while older larvae are generally darker green with a dark and light line running along the side of their body and a pink or yellow underside

• Cause• Insect

Flea beetlesVarious

Symptoms

• Small holes or pits in leaves that give the foliage a characteristic “shothole” appearance; young plants and seedlings are particularly susceptible; plant growth may be reduced; if damage is severe the plant may be killed; the pest responsible for the damage is a small (1.5–3.0 mm) dark colored beetle which jumps when disturbed; the beetles are often shiny and metallic in appearance

• Cause• Insects

Flea beetles are often metallic in appearance

LeafminersLyriomyza spp.

Symptoms

• Thin, white, winding trails on leaves; heavy mining can result in white blotches on leaves and leaves dropping from the plant prematurely; early infestation can cause fruit yield to be reduced; adult leafminer is a small black and yellow fly which lays its eggs in the leaf; larave hatch and feed on leaf interior

• Cause• Insects

Leafroller (Omnivorous leafroller)Platynota stultana

Symptoms

• Leaves of plant rolled and tied together with silk webbing; feeding damage to rolled leaves; defoliation of plant; silk webbing may also be present on fruits and fruits may have substantial scarring from feeding damage; larvae wriggle vigorously when disturbed and may drop from plant on a silken thread

• Cause• Insect

larvae

Spider mites (Two spotted spider mite)Tetranychus urticae

Symptoms

• Leaves stippled with yellow; leaves may appear bronzed; webbing covering leaves; mites may be visible as tiny moving dots on the webs or underside of leaves, best viewed using a hand lens; usually not spotted until there are visible symptoms on the plant; leaves turn yellow and may drop from plant

• Cause• Arachnid
