PART 1V. 2:7 3. That, although a great deal of experimental and investigational work has been done on Sudan, American, and Spiny Boll Worm, this Section is not in a position to make any general recommendations. No economic means of control have yet been devised, but the Section 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 : — » 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. That the programme of the work to be adopted should be drafted by the staff of the centre chosen for the major investigations. That this programme should be circulated to the Depart. ments of Agriculture in other Cotton growing areas, with a view to complementary work being undertaken by them. GENERAL ENTOMOLOGY AND MYCOLOGY. 9. That much more work should be done by Entomologists in regard to the Pheidole ant, and that the question of baits and the destruction of nests is worthy of close investigation. As this ant was of great importance in Kenya, it was recommended that a thorough investigation should be undertaken in Kenya. 10. That the Entomologists of Kenya and Uganda should meet and discuss the question of preventing the spread of Stephanoderes hampei into Kenya after visiting Coffee areas to the east and west of Mount Elgon. 11. That the conditions and problems in South Africa are so entirely different from those in the tropical East African Colonies that the problem of the control of Cut-worms is one for solution in the various territories concerned. ' (a) That each participating territory should arrange to prepare lists of injurious insects and fungoid diseases, with their food plants and status as pests. and to interchange such hats. 5:
