Red Cotton Bug (Dysdercus cingulates) රතු කොට්ට මකුණා

#Dysdercus cingulatus grows to a length of 12 to 18 mm (0.47 to 0.71 in). It is mainly red but has a white collar and three black spots.
Biological background
Like other true bugs, Dysdercus cingulatus sucks fluids from its host plants. The only part of the cotton plant affected by this pest is the flower and the seed capsule or boll. As this develops, the insect thrusts its rostrum between the carpels and sucks fluids from the still soft seeds inside. Micro-organisms are admitted in the process and may make the boll contents rot or the lint become discoloured. Meanwhile, the seeds wither, the fibres may fail to expand and the boll may abort.[1] When the seeds of a host plant ripen and it becomes unsuitable, the adult insects migrate to new host plants of the same or different species. While away from their hosts, they feed on nectar and fruit of non-host plants, and can survive for several days without food. They seem fond of citrus fruits, but this may merely be because there are often citrus plantations in close proximity to cotton fields.
