PART VI ENTOMOLOGY AND MYCOLOGY. CorToN PESTS. 1. That the Platyedra erebodoxa, Meyr (M.S.), discovered by Mr. Hancock, shows no indication of becoming a pest of cotton mn Uganda. (a) That steps be taken to secure from each African territory a report upon the presence or absence of Pink Boll Worm therein, together with a carefully prepared map showing the different cotton growing districts; and, if Pink Boll Worm is present, the areas known to be infested. 'b) That, from the information so supplied, a map of Africa be prepared for the use of African Entomologists, showing the distribution of cotton cultivation and of Pink Boll Worm. That the delegation from South Africa, as represented by the Government officials and the officials of the Empire Cotton Growing Corporation, be asked to initiate this project and secure the publication in South Affica of the desired map for distribution. 3. That although a great deal of experimental and investigational work has been done on Sudan, American and Spiny Boll Worms, this Conference is not in a position to make any general recommendations. No economic means of control have yet been devised but the Confer- ence is of opinion that further investigations are desirable and necessary. 4. That there is danger of Apion becoming a serious pest if uprooting and burning is not resorted to, and that in Tanganyika uprooting and burning has been found to be entirely successful. 5. That the status of the wild food plants of the Sudan Boll Worm is of great importance and calls for further thorough investigation. 6. That the control of Aphids and Jassids by fungi should be further investigated. 7. That a wider survey is necessary before any definite information can be supplied in regard to the natural occurrence of major pests. and their occurrence under conditions of cultivation. 8. That, in view of the immense importance of Cotton Staining and Internal Boll-rots to the future development of Cotton growing in Africa, it is recommended : — (a) That thorough investigations should be undertaken into the problem, with special reference to the possible role played in transmission by Dysdercus and other suctorial insects. -* That in some one centre an adequate staff should investigate thoroughly the whole problem in all its aspects, and that the Government of South Africa should be approached, in the first instance. with a view to undertaking this work. 201
