any method short of netting, will have any radical effect 

 on the flies under the conditions at Pusa. Methods for 

 destroying the mango fly (the most destructive species 

 in Behar) have been tested with success. Mr. Froggatt, 

 Entomologist to the Government of New South Wales, 

 visited Pusa in June 1908 for the purpose of obtaining 

 information on the subject of fruit flies, as the Australian 

 fruit flies are related to those found in India and consti- 

 tute a very serious obstacle to the successful cultivation 

 of fruit there. Since his return he has been supplied with 

 fruit flies specimens for the purpose of assisting his in- 

 vestigation on the Australian species. Arrangements 

 have been made with Professor Silvestri to supply para- 

 sites of some of the south Indian species in the hope that 

 they may be utilised against the olive fruit fly, a species 

 which inflicts great damage in Italy. 



Among blood-sucking flies attention has been directed 

 chiefly to the life-histories of sand flies, tabanid^ and 

 muscidse, and the Pusa species are now fairly well-known. 

 A number of specimens have been received from various 

 parts of India, from the officers of the civil veterinary 

 departments and from medical men. A report on 800 

 specimens received from Bengal was communicated to 

 Mr. D. Quinlan, Superintendent, Civil Veterinary Depart- 

 ment, Bengal, and data as to the distribution of the various 

 species are thus being obtained. 



A number of specimens have been identified for medi- 

 cal men and for private individuals, and various enquiries 

 regarding blood-suckers, parasites, infective and predace- 

 ous insects, have been received and answered. A report 

 on the value of certain insecticides advertised as being 

 efficacious against various parasites, has been supplied to 

 the Inspector- General of Agriculture in India. Arrange- 

 ments are in progress for supplying Indian blood-suckers 

 to the Sleeping Sickness Commission in Uganda for the 

 purpose of testing the possibility of sleeping sickness being 

 transmitted by any Indian species as well as by the tsetse
