INSECT PESTS AND THEIR CONTROL 147 



the sweet pulp surrounding the seeds. Fortu- 

 nately, by the time the pulp is sweet and palatable 

 to the grub, development of the seed is practically 

 complete, so that little damage can be done. These 

 insects would be a serious pest where the product 

 was a fruit, but as, with us, it is only the seed 

 which is of value, disfigurement of the fruit is of 

 minor importance. 



The larvae in the pulp are destroyed in the ordi- 

 nary process of fermentation, both of Coffee and 

 Cocoa. If the recommendations we make regard- 

 ing the gathering up of all fallen Coffee berries 

 when a tree has been picked, be carried out, very 

 few of the maggots will escape the fermentation 

 process. 



Coffee Berry Beetle. This is the most serious 

 pest which has so far troubled the Coffee planter 

 in Uganda. The eggs are laid at the point of the 

 half-formed berry, and the grubs, as soon as 

 hatched, begin to burrow into the berry. They 

 there mature, and then bore another passage out. 

 Very little can be done to control the pest, except 

 to pick off and destroy infested berries. Of course, 

 if this measure is adopted, the destruction of the 

 berries must take place whilst the insect is inside
