Cotton Pest

Interstate rights-of-way may serve as weed host reservoirs for the tarnished plant bug, an insect pest of cotton. Management of these rights-of-way may have an impact upon cotton pest management. In a 3-yr study, time of mowing, frequency of mowing, and sulfometuron methyl applied against overwintering rosettes influenced the cover of annual fleabane and wild carrot, which harbor tarnished plant bugs.

Cotton Pest

Lygus simonyi has been found to cause serious damage to cotton in Uganda, by sucking the young leaves and apical buds, by retarding the growth of the branches, and by sucking the young bolls.There are indications that soil and climatic factors are of importance in controlling this insect ; excessive succulence of the plant appears to be one factor associated with severe damage.

Cotton Pest

The cotton stem moth, Platyedra vilella (Zeller), was not known to occur in the United States prior to 1951. In August of that year, larvae of the species were found infesting hollyhock plants at Mineola, New York, by J. H. Maheny, a plant quarantine inspector of the port of New York. Adults were reared from additional material collected the following year, an indication that the species had become established. How or when P. vilella was introduced has not been determined, but doubtless it was only recently.

Cotton Pest

Methods for the quantitative survey of the incidence of Heliothis armigera have been in continuous operation in the Barberton area of the Eastern Transvaal from 1929 to the present; since 1933 the Survey was operated similarly in Swaziland and Northern Natal.It was accepted early that the bollworm situation in cotton, which primarily it was desired to ameliorate, depends largely upon the influences exerted by other food-crops of the insect grown prior to and in association with cotton, and the investigations were instituted with a view to acquiring the fullest information on the incidence, habits and reactions of H. armigera with respect to the chain of cultivated and natural food-plant situations existing under differing climatic conditions in the course of the year.The present paper is the first of a series communicating the results of investigations which proceed in various directions from information supplied by the Cotton Pest Survey centred upon Barberton. The paper deals with the annual course of bollworm incidence as indicated, in the first instance, by egg counts taken twice-weekly, year by year, in examples of all food-plant situations according to methods of sampling and calculation devised here.
