Dusky Cotton Bug


Recognize the problem


Though the bug sucks cell sap from leaves, flowers and growing soft tissues of


upper stem, the main damage is when they get crushed at the time of ginning,


thus staining the lint and decreasing the market value of the cotton. The bugs


suck the sap in groups from the immature seed which consequently do not


ripen and remain light weight. The bugs also cause nuisance to workers during


picking.


The adults are about half the size of a fingernail and are dark brown in colour.


The winged adults have dirty white semi-transparent wings and the young are


round. The eggs, laid on the lint of half opened bolls of cotton, are white and


cigar shaped. They are laid in clusters of

3-18

.


Background


The dusky cotton bug used to be a minor pest of cotton but its importance has


grown in the last few years, as populations are becoming larger. A number of


generations throughout the year have been observed. Dusky cotton bugs also


live on other plants, such as okra.


Management




The easiest control is to remove alternate host plants like okra etc.


before and near the main crop




Collect the adults and nymphs by shaking the bolls into vessels with


kerosinised water




Spray chlorpyriphos @ 1000ml per 100 litres of water
