 [Received 19th April 1920.] 



The measures in Geimany for controlling the bot-fly, Hijpodcrma 

 bovis, were interrupted in 1914 owing to the outbreak of war. As a 

 result this pest has spread to previously uninfested locaUties. The 

 necessity for organising a systematic campaign, which should include 

 the teaching of bot-fly control measures in the village schools, is 

 emphasised.

The insects noxious to mammals either in the form of direct parasites 

 as or as transmitters of disease are reviewed. The preventive as well 

 remedial measures against these pests are outhned, and the import- 

 ance of apphed entomology with reference to their control is 

 emphasised.

The danger of the spread of malaria in Germany owing to the 

 demobiUsation of troops is pointed out, and the usual precautionary 

 and remedial measures including notification of cases are discussed. 

 In an appendix advice is given on the best method of collecting and 

 forwarding suspected material for identification, as well as the 

 preparation of blood smears. Anopheles maculipennis, Meig., 

 A. bifurcatus, L., and A. jilumbeus, Hal. {Coelodiazesis nigripes, Staeg.) 

 are the mosquitos of chief importance in Germany.

The results with subtertian, tertian and quartan malaria are first 

 given separately, and after correction the final results with experiments 

 on 1,058 mosquitos are shown together in one table. 



In the case of Anopheles ludlowi and A. hgrcamis (sinensis) 

 both the stomach and salivary glands were examined ; in the case of 

 the other species the stomach only. 



With A. ludloivi the percentages for subtertian, tertian and quartan 

 malaria were 100, 80 and zero ; with A. hyrcanus these figures were 5, 

 40*6 and 1 ; with A. wnbrosus there was a 5 per cent, infection with 

 quartan ; with A. barbirostris 13 per cent, with quartan ; with 

 A. punctulatus 4-3 per cent, with subtertian ; and with A. hochi 

 16 '7 per cent, with tertian. 



Negative results were obtained with A. cdbotaeniatits , A. indefinituSy 

 and A. Icucosphgrus.
