Dorylus orientalis, Westw. 



F. I.,Hym.II.,i3p. .1-5, fi". (3-7. 



Occurs throughout India, Burma ami Ceylon in the Plains, and 

 frequently does damage by attacking the underground portions of plants. 

 At Pusa it damages roots and undergrou)id parts of plants such as potato, 

 cabbage, cauliflower and vegetables generally. At Cawnpur also it has 

 been found damaging potato. At Shahabad, in the United Provinces, 

 it has been noted as damaging early-sown groundnuts and at Gadag 

 Farm it was found to eat out groundnut kernels when the nuts were 

 lying in a heap after harvest. In Ceylon, both at Peradeniya and 

 Dikoya, the workers have been observed to be destructive to the roots ^nUievis. 

 of potato and other vegetables. ^^- ^^eteher. 



It may be controlled by the use of crude oil enuilsion applied to the 

 «oil around the plants. It is usually only young plants that are attacked. 



Have you tried lime ? 



No ; we have not tried lime at Pusa as there is already an excess of 

 lime in the soil here. A few years ago we had a bad attack of this ant 

 on young cabbages and I tvied various repellents, including apterite, 

 naphthaline, and phenyle, and found that crude oil emulsion was the 

 most successful. 



Dorylus labiatus, Shuck. 



F. I., Hym. II., pp. 2-3, fit. 1-3. 



Occurs throughout India, but not known from Ceylon, Assam or 

 Burma. Is apparently carnivorous as a rule, attacking ants {Pheidole). 

 Has only once been sent in as a pest, when it was attacking potato tubers 

 ^underground at Sidapur, Coorg.

It is a leaf cutting bee ; at Pusa it cuts leaves from tur {Cajanus indicus)

 circular patches out of the leaves.
