Cotton Stainers

Cotton-stainers, Dysdercus spp., are most important factors affecting the growing of cotton in the West Indies and elsewhere, on account of the fact that they convey certain bacteria and the spores of various internal boll fungi which cause staining and rotting of the cotton lint.

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.

There has been much confusion in the taxonomy of the species of Dysdercus in the Caribbean area, and this contribution is an attempt to straighten out the nomenclature and synonymy for future workers on these important pests, until such time as a complete revision of the Neotropical Dysdercus can be attempted.

(1) There are two forms of D. superstitiosus, F., in Nigeria, which are designated banded and spotted forms in the present paper. The banded form appears on cotton earlier in the season than the spotted, and it remains on the crop longer. Migration to cotton is gradual in the case of the banded form, while a sudden influx of migrants of the spotted form commences in October. Many spotted adults migrate to Bombax and Sterculia between January and March, whereas the banded form remains on the cotton until it is uprooted at the end of March. The spotted form is far more numerous than the banded on maize and guinea corn.(2) There is considerable variation in the colouration of adults of the spotted form; at Ibadan about 99 per cent. of the migrants to cotton are yellow or orange in colour, while the adults of the filial generations produced on cotton are almost always red in colour (a few individuals are deep orange-red). These colour variations are thought to be of seasonal origin.(3) D. superstitiosus is the most prevalent species on cotton at Ibadan, Ilorin, Oyo, Zaria and Kano; melanoderes is of equal or greater importance in the forest zone at Ilugun and occasionally is numerous at Ibadan; fasciatus is of importance in savannah country at Oyo; haemorrhoidalis is rare on cotton. No evidence has been obtained that any one of these species is a varietal form of another species. Both forms of superstitiosus are widely distributed in Nigeria.(4) Migration to cotton is induced by the flowering of that crop. The maximum weekly migration has occurred between the weeks ending 15th October and 7th November in five localities in the last three years; viz., at the time of, or soon after, the maximum flowering of the cotton crop. There are indications that there is a tendency for stainers to migrate in a southerly direction, probably as a result of the desiccating harmattan wind from the Sahara.(5) The principal alternative food-plants of stainers in the Ibadan district are: Bombax sp., Sterculia sp., Hibiscus esculentus, H. sabdariffa, Urena lobata, and Abutilon zanzibaricum. At Ilorin, silk-cotton trees (Bombax), H. esculentus, H. lunariifolius and U. lobata are the most important alternative food-plants.(6) A rhythm exists in the weekly proportions of the sexes during the cotton season; males predominate among the early migrants to cotton and among the first individuals to mature of each generation. This rhythm appears to be the result of shorter period of post-embryonic development in the case of males than in that of females derived from the same batch of ova.

From the above it will be seen that in the writers' opinion, based it must be admitted on but a single year's observations, the three species of Dysdercus (D. fasciatus, D. nigrofasciatus and D. superstitiosus) occurring in the northern rain-cotton belt of the Sudan are essentially associates of the tebeldi and are not as yet other than accidental pests of cotton. By this is meant that there is no definite migration from the tebeldi to cotton, nor are wandering adults greatly attracted by cotton. The dispersal of a proportion of the adults composing a colony on a tebeldi is the natural effort on the part of the species to establish itself on other tebeldis. Emigrants from a colony that in the course of their wanderings chance on cotton may remain to breed. It is possible that when cotton has been grown in the district on a large scale for some years, the bugs, unless they are kept in check, may develop the habit of migrating definitely from the tebeldis to the cotton and, later in the season, from the cotton back to the tebeldis.The most promising line of attack appears to be that of destroying, so far as possible, the colonies on the tebeldis during the active breeding season.The writers' thanks are due in particular to Mr. G. F. March, Inspector of Agriculture, who in a variety of ways has rendered them the greatest assistance in their work.

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)

Cotton Stainers

In the February number (1928) of this Journal, a most interesting and valuable paper was published by Mr. F. D. Golding, Government Entomologist of Nigeria, on the bionomics of cotton-stainers (Dysdercus). In a footnote on page 319 of this paper it was suggested on my authority that three of the seven species mentioned by him as occurring in Nigeria were probably wrongly identified, since no representatives of these three species were present in the Nigerian material in the British Museum. Since then I have been able to examine Mr. Golding's collection and can state definitely that the specimens of Dysdercus nigrofasciatus, Stål, and D. migratorius, Dist., taken in Nigeria, were correctly identified. D. intermedius, Dist., however, does not, so far as is known, Occur in Nigeria. To the species mentioned by Golding as occurring in that country must be added D. antennatus, Dist., which however is probably generically distinct from typical Dysdercus species.
