VoGEL ( R . ) . Ueber Vorkommen und Biologie von A nop/uies im Bereicli 

 des Etappangebietes der 5. Armee (ostliches Frankreicli und 

 angrenzendes Belgien). [The Occurrence and ]:>i(jl()iiy of Ano- 

 pheles in the Region of the German 5th Ami}' (Eastern France 

 and adjoining Belgian Territory.] — Arch. Schiffs- u. Trop-Hyg., 

 Leipsig, XXV, no. 9, September 1921, pp. 279-284. 



These observations were made in the Meuse region between Sedan 

 and Verdun and in the hilly and wooded French and Belgian territory 

 to the east of it. Anophelines occurred wherever suitable conditions, 

 especially stagnant water with green vegetation, were present. The 

 area is densely populated, and there is no lack of food for moscpiitos. 

 The latter were very abundant in the low land near the Meuse canal, 

 the numerous marshes and places subject to flooding being most 

 favourable breeding-places, and also on the hills along the Meuse, 

 which are wooded and contain many pools. The Meuse canal itself 

 was free from larvae, at least within a few hundred yards of the locks. 



The absence or rare occurrence of Anophehnes in the French indus- 

 trial district of Longwy and Mont St. Martin is due to the enormous 

 development of ironworks which pollute nearly all stagnant waters 

 and prevent breeding. 



Sheds for cattle and sheep yielded most mosquitos ; pig sheds were 

 not so markedly infested, and stables for horses even less. In the open, 

 Anophelines were seen daily throughout the summer, and were common 

 on walls sheltered from wind and light. 



Hibernating individuals were scarce and were represented only by 

 Anophsles macnUpennis. A. bifiircatns appears to hibernate in the 

 larval stage. Cellars, store-rooms and ground-floors were the winter 

 quarters of the few individuals observed. These two species occur 

 together in the Meuse and Crusnes valleys, and probably do so 

 throughout the whole territory. 



A. niacnUpennis attacked chiefly at evening twilight and during the 

 subsequent hours, whereas A. hifurcatns did so in the early morning 

 and also in daylight. A . macuUpennis attacks man in the evening in the 

 open, but the author was only bitten in the absence of domestic animals. 



Roubaud's observations around Paris [R.A.E., B, viii, 141] seem 

 therefore to hold good for the Meuse region, but the author points 

 out that A. macnlipennis , both in France and Germany, is widespread, 

 not only as a domestic species but also as an open air one. On the 

 other hand, A. bifiircatiis cannot be regarded as a purely open air 

 species, for it was taken, full of blood, together with A. macnlipennis 

 in cattle sheds. 



The numerical proportion between A. macnlipennis and A. hifur- 

 catns varies at different times in the same sheds. At Inor the relation 

 was as 9 to 6 in July, but during September A. bifnrcatns slowly 

 increased, so that on 26th September 21 individuals were taken to 1 

 of A. m%culipennis. 



There is no certain record of a case of locally acquired malaria 

 infection in the territory dealt with.
