68 REPORT OF THE AGRICULTURAL RESEARCH 



In the United Provinces, active measures have been 

 adopted against the Rice Grasshopper, Rieroglyfhus 

 furcifer, a serious pest to sugar-cane. 



In Bengal successful demonstrations were made against 

 the Potato Moth {Phthorimcea operciilella Zel.) and the 

 advantages of storing seed-potatoes under sand v^ere de- 

 monstrated to the Kaoris as well as to others engaged in the 

 potato trade. A leaflet, explaining the methods to be 

 adopted against the moth, was distributed at Tirhut and 

 Bankipore Exhibitions. The campaign against A gratis 

 ypsilon was continued. The picking off of the first brood 

 of caterpillars and the setting up of Andres-Maire traps 

 reduced the loss during the past year to a minimum, so much 

 so that out of a total area of 20,000 bighas, only 2,000 were 

 affected. Eri work was begun and the Department com- 

 pleted a Crop-pests Handbook. 



In Eastern Bengal and Assam, the Ufra disease of 

 paddy, probably caused by an eel-worm, was investigated. 



In Baroda, the campaign against the Katra (Hairy 

 Caterpillar) was continued. Practical demonstrations were 

 made and rewards were offered to cultivators for keeping 

 the field embankments clean as a preventive against the 

 pest. 



In the North-West Frontier Province, on the resumption 

 of duties by the Entomological Assistant, a survey of the 

 crop-pests of the Province was started and effective 

 measures were taken against the Peach and Tobacco 

 Aphides. 



5. Corresfondence. — The work of replying to the 

 numerous requests for information and advice on the many 

 branches of entomological work continues to demand much 

 time and attention, but in view of the importance of this 

 part of the work of the section, no efforts have been spared 

 to give applicants as full information as possible. Seventy- 

 eight parcels of insects were received for identification and 

 suggestion of methods of treatment and this was done as far 

 as we were able in each case.
