Medium to large-sized nymphs and adults feed on seeds in developing cotton bolls (Sprenkel 2000). The cotton stainer derives its name from its habit of staining cotton an indelible brownish yellow. The feeding activities of cotton stainers on cotton produce a stain on the lint which reduces its value.
Which one of the following is not the drawback of biological control?
If you’re looking to completely wipe out a pest, biological control is not the right choice. Predators can only survive if there is something to eat, so destroying their food population would risk their own safety. Therefore, they can only reduce the number of harmful pests.

What kind of damage does Dysdercus cingulatus do to cotton?
An early indication of attack by D. cingulatus is the feeding damage caused by adult and nyphs on the flower buds and seeds of cotton. Feeding of this and other species of Dysdercus on cotton bolls causes the boll to abort and shed ( Pomeroy and Golding, 1923) (see Economic Impact).
Which is the best way to get rid of Dysdercus cingulatus?
One of the most effective methods is the removal and destruction of all standing cotton by a fixed date, as soon as the cotton has been picked and ceased to bear any profitable yield ( Pomeroy and Golding, 1923 ).
