Dysdercus Cardinalis

Cotton stainers (Dysdercus spp.) are members of the family Pyrrhocoridae and many are pests of cotton throughout the tropics. Ten species are found in Africa (Pearson, 1958). Three of these have been established in colonies at Arusha, Tanzania. They are D. cardinalis Gerst., D. fasciatus Sign. and D. nigrofasciatus Stål.

Different Parts

1. The preparation of isolated Malpighian tubules is described. The rate of urine flow increases with increasing serum dilution, and vice versa. Urine is almost isotonic with haemolymph over a wide range of osmotic pressure. 2. Serum collected from 3-day-old insects promotes urine formation, whereas that from 6-day-old insects does not. 3. A factor which was extracted from the m.n.c. accelerates the rate of urine flow, from a normal value of 0·87 to 3·1 mm.3 x 10- 3/min. The osmotic pressure of the urine, however, remains unchanged. 4. The hormone concentration of different parts of the nervous system was assayed with these isolated tubules. Most activity occurs in the m.n.c., but some activity is present in extracts from the c.c. and the fused ganglionic mass in the mesothorax. 5. Malpighian tubules isolated from 6-day-old insects remain inactive, but after the addition of hormone they immediately begin to produce urine. 6. These observations have been incorporated into a tentative hypothesis on the control of excretion in Dysdercus.

Cotton Pest

Four species of "cotton stainers," also known as "red bugs," are known from Florida. However, the most important of these is the cotton stainer, Dysdercus suturellus (Herrich- Schaeffer). Morrill (1910) stated the cotton stainer was the most destructive cotton pest in Florida. Currently, the cotton stainer is a minor pest of cotton, and then only in the southern part of the state (Sprenkel 2000). This document is EENY-330 (originally published as DPI Entomology Circular 48), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida. Published: June 2004. Revised: March 2005. EENY330/IN606: Cotton Stainer, Dysdercus suturellus (Herrich-Schaeffer) (Insecta: Hemiptera: Pyrrhocoridae) (ufl.edu)
