•The major cotton producing countries are USA, China, India, Pakistan, Uzbekistan,
Turkey, Brazil, Greece, Argentina and Egypt.
•These countries contribute about 85% to the global cotton production.
•India is the largest producer of cotton in the world.

About Cotton (Gossypium)

3. •The total global potential loss due to pests is more than 80% in cotton production.
•More than 1326 species of insects have been reported attacking cotton in the
world. However, in India, only 162 species have been recorded, among which only
15 species may be called as major pests.
•In the cotton ecosystem, the introduction of Btcotton has caused changes in
insect pest complex.
•The incidence of bollworm i.e. American bollworm, pink bollworm and spotted
bollworm is low on Btcotton.
•However, Btcotton does not provide effective control of tobacco caterpillar and
sucking pests as aphid, whitefly and mealy bug.

6. c) Marks of Identification
Nymph:They are red colourwith black and
white dots.
Adult:
They are elongated, slender, crimson red
with white bands across the abdomen.
Head is red with a white collar, abdomen is
black and forewings have two black dots.
The membranous portion of their forewings,
antennae are black in colour.
Both nymph and adults has piercing and
sucking mouthparts.

7. d) Life cycle
In the spring, the bugs becomes active and lays about 100-
130 eggs in the soil or nearby the host plants.
The eggs are spherical and bright yellow in colour, laid
singly or in small clusters.
After an incubation period of 7-8 days, nymphs hatch and
start to feed on cotton plants.
Freshly hatched nymphs are pale orange, later on turned
into red colourwith black and white dots.
There are 5 nymphalstages and development is completed
in 49 to 89 days.
The female adult was larger than the male.

8. e) Nature of damage
Both adults and nymphs suck cell sap from leaves and green bolls of cotton
and stain the lint.
The damaged tissues are colonized by microorganisms that cause boll rot
and discoloration.
The bacteriumNematosporagossypiienters the site of injury and stains the
fibre.
It cause boll abortion, premature opening and early shed of bolls.
The seeds produced are smaller with reduced oil content and
lower germination rate. These seeds are not fit for sowing.
A high infestation can cause a severe loss in quality due
to the stained lint.

9. f) Control measures
1.The pest can be controlled by spraying the crop by using 0.1% BHC,
0.02% endrin, 0.05% malathion, 0.1% DDT.
2. Dusting the crop with 10% BHC is also effective.
ii) Cultural methods
1.Remove alternative host plants and other wild plants of Malvaceaefamily.
2.Remove and destroy all standing cotton plants as soon as the cotton has been picked.
3.Deep ploughing to expose the buried eggs to sunlight and predators.
iii) Chemical methods
1.Hand picking and killing of insects in kerosinisedwater, if population is still small.
2.the infested leaves or bolls can be shaken in water.
3.Moistened cotton seeds should be hanged up at different places in the field where bugs
congregate, they may get killed in the kerosene water.
