The following series of practical accounts of the loheat iveevil has been ohtxined by 

 Messrs. Ralli Brothers of Calcutta from their different Agencies, in answer to a series 

 of questions addressed to them in January 188S : — 



Calcutta, • 



The 26th January 1888. 



1. The percentage of loss known to be caused by the weevil in granaries is as follows : — 



Maximum . ..... 5 per cent. 



Minimum . . . . . . 1 „ 



Average . . . . . . 2^ ,, 



2. The soft varieties of wheat are more affected than other varieties. 



3. Delhi, Buxar, and Hansklially wheat is more affected than wheat from other loca- 

 lities. 



4. The pest commences from July in Lower Bengal and August in up-country, and 

 does more damage from September. From the beginning of the crop till the latter end of 

 June wheat remains almost free from the attack of weevils. 



5. The weevil attacks rice and maize besides wheat. 



6. The wheat weevil is found nowhere besides in granaries. 



7. To the best of our belief the only remedy employed against the weevil in India is 

 exposure to the sun. With regard to the remedies mentioned we cannot express an 

 opinion. We only wish to remark that ventilation causes the grain to be more infested by 

 weevils, as wheat, packed in bags, gets more weevilled than wheat stacked in bulk or pile 

 which is more air-tight. 



8. We believe that sparrows, crows, and other birds destroy weevils, 



9. We are not in a position to answer the question of how many generations there are 

 in the year. 



10. There are four species of insects infesting edible grains, of which two kinds are 

 found to attack rice ; and again one species out of these two attacks wheat and maize, 

 and two kinds infest pulses.
