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.
