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 Conference
 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.
