Introductory Note. 



THE cotton plant is attacked by a variety of insects, but 

 only three of them do serious damage to the crop. These occur 

 regularly every season, attack the fruit and lessen the yield. 

 These pests- are : 



(1) the Bollworm. 



(2) the Red Cotton Bug. 



(3) the Dusky Cotton Bug. 



All of them are easily recognised in the field : and the ob- 

 ject of this short note is to put in the hands of cultivators simple 

 means of preventing these pests from doing damage.
