Cultural Control Some cultural methods may reduce damage caused by D. 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, The elimination of trees, such as Bombax, and other wild malvaceous plants is also strongly recommended. Chemical Control Due to the variable regulations around de- registration of pesticides, we are for the moment not including any specific chemical control recommendations.
The boll is the only part of the cotton plant that is attacked by D. When the bolls are ripening and the carpels opening, the bug inserts the rostrum between the carpels and sucks the juices from the soft and developed seeds, injuring the cotyledons and causing the seed to wither and the lint to be uniformly stained.
In many cases the fibre does not mature and expand but remains adhered together causing the lint to become quite valueless. Dysdercus species are thought to be the most serious pests of cotton van Doesburg, In piercing the boll they introduce microorganisms which cause the bolls to rot, or the lint to become discolored, hence the common name 'cotton stainers'; this greatly reduces yields in cotton-growing countries.
