Dysdercus Luteus
''Dysdercus'' is a widespread genus of true bugs in the family Pyrrhocoridae; a number of species attacking cotton bolls may be called "cotton stainers." Description Species may be confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head. They can be readily distinguished from most other genera of Pyrrhocoridae by the strong white markings at the junction of the head and thorax, and along the sides of the thorax, and often abdomen. Ecology Some members of the genus attack cotton bolls and are known as "cotton stainers." There are several species of tachinid flies that are parasitoids of ''Dysdercus'' nymphs and have been used as biocontrol agents.

Dysdercus Cingulatus
''Dysdercus cingulatus'' is a species of Hemiptera, true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. It is a serious Pest (organism), pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton-staining fungi as they do so. Description ''Dysdercus cingulatus'' grows to a length of . It is mainly red but has a white collar and black hemelytral spots. It is closely related and very similar to ''Dysdercus koenigii'' but ''D. cingulatus'' is slightly larger and the femora have varying amounts of black while ''D. koenigii'' has completely red femora. Distribution ''D. cingulatus'' is reported to occur in Sumatra, Borneo, the Philippines, Sri Lanka, northern India, western Pakistan, Bangladesh, Cambodia, Thailand, Papua New Guinea, and northern Australia. The exact distribution is difficult to ascertain because of historical confusion between this species and ''D. koenigii''. H ...
