ENTOMOLOGICAL PESTS AND PROBLEMS OF SOUTHERN 



NIGERIA. 



By A. D. Peacock, B.Sc. 



Late Entomologist to the Agricultural Department, Southern Nigeria, 



(Plates XXIII— XXVIII.) 



The account of the entomological work carried out by the writer in Southern 

 Nigeria falls naturally into three sections, October- December 1911, January- 

 June 1912, and June-October 1912. During the first period, work, principally 

 on cotton pests, was carried on at the Agricultural Headquarters, Ibadan, 

 particular attention being devoted to the Red Cotton Stainer Bug. The second 

 period was given to travel (fig. 1), when the entomological problems of the different 

 districts were studied on the spot, and lectures were given en route to meetings of 

 native chiefs, native agricultural societies, schools and school teachers. 

 The third period was spent in dealing with the insects of nursery cocoa, cotton, 

 maize and yam. Lectures and demonstrations were given to agricultural pupils. 

 A small amount of work with insecticides was attempted. In conjunction with 

 the Mycologist, rules were formulated for conducting the three first Fumigatoria 

 of the Colony.
