mOCEEDINGS OF THE THIKD ENTOMOLOGICAL MEETING 



We at Pusa have been working on Cotton Bollworm, Earias fabia and 

 E. insulana. and find that cultural methods surely go a long way in pro- 

 tecting the plant. One year [1911] our plants were attacked by "Red 

 Spider " ; we sprayed with crude oil emulsion and, as Mr. Andrews has 

 pointed out, we had no success. Then we sent around boys with brooms 

 to rub the webbing off the plants. Next we tried spraying with a force- 

 pump so that the liquid might reach the underside of the leaves. Next 

 year we increased the distance between the plants to be three feet apart 

 so that the plants got plenty of light and air. Thus cultural methods 

 were found useful. We also found that inter-cultured plants were able 

 to throw off the attack. There is scope for work along the lines suggested 

 by Mr. Andrews. 



Chilomenes sex-maculatus eats the Red Spider. 



Mr. Andrews has said that termites attack tea-bushes at the collar. 

 Here at Pusa they attack the roots of trees also. In Assam it may be 

 the specialized habit of those termites not to go below the collar. 



I have had some experience with sugarcane in which the setts were 

 put down six inches below the soil. When we cut out the dead-hearts 

 we find that the setts are attacked by termites. This shows that the 

 termites of Assam have a special habit of not going down below the 

 soil. 



It merely shows, what I have pointed out before, that different species 

 of termites have very different habits. 



If there are no further remarks on Mr. Andrews' paper, we will go 

 on to the Annotated List of Indian Crop-pests, with which we will take 

 the paper on Indian Fruit-pests in order to save time, as many general 

 crop-pests attack fruit-trees also and there will be no object in dealing 

 with such insects twice over. We have been through the list of our 

 insect pests on previous occasions. Four years ago we dealt with them 

 according to the Orders and Families of the insects concerned. Two 

 years ago we went over them according to the crops which they attack, 

 and the whole information up to then is on record in the Report of the 

 Proceedings of our Second Meeting, and there is therefore little need to, 

 go into too great detail ; so at this Meeting we will give only a summarized 

 account of these insects, adding especially any new information which 

 we have been able to obtain about them during the last two years, and, 

 instead of discussing the whole papers after they have been read, I will 

 ask you to give any further remarks on each insect as we deal with it. 

 AVe will now run briefly through these insect pests, taking them in sys- 

 tematic order and commencing with the Hymenoptera.
