Speckkaferlarven [Dermestes lardarius^ L.) als Schadiger im GeflugelstalL 



[Dermestes lardarius, L., as a Pest of Poultry-houses.] — Zeitschr.

Dermestes lardarius, L., is recorded as occurring in poultry houses 

 where much damage is caused by the larvae attacking newly emerged 

 ducklings and chickens. In the case under observation the beetles 

 were found breeding in a pigeon loft that was immediately above the 

 poultry house. The infestation was noticed in 1918 and in June of 

 that year the premises were well cleaned with dilute lysol and soda ; 

 when inspected in November 1918 no fresh infestation was noticed.

The Staphyhnid beetles, Paederus ruficollis, F., P. gemellus,. 

 Kraatz, P. riparius, L., P. fuscipes. Curt., P. limnophilus, Er., and 

 P. litoralis, Grav., are recorded as being capable of producing skin 

 irritation in man [R.A E., B, iv, 15, 51, 167.] It is also noted that 

 another Staphylinid, Oxytelus tetracarinatus. Block, frequently occurs 

 as a foreign body in the eye, causing great discomfort.

Among 2,793 flies caught in a small room that had been used for 

 storing potatoes, 2,177 proved to be Calliphora vomitoria, L. At 

 the time of this observation the room in question had been cleaned 

 out and shut up for about 6 weeks. As this large number of flies 

 must have been the descendants of a few hibernating individuals or 

 of adults that subsequently emerged from pupae accidentally carried 

 in with the potatoes, the necessity lor the application of early remedial 

 measures is emphasised.

The eggs of Fannia canicularis, L., are laid from the beginning 

 of the warm season until the autumn, preferably on decaying parts 

 of plants. They hatch in about one to two days. Adults may be 

 found in human habitations as well as stables, etc., but this fly never 

 becomes a nuisance like Musca domestica, L., although it may prove 

 a passive carrier of disease. Owing to its habit of -circling round 

 some dependent object near the ceiling it may be easily caught by 

 . means of suspended gummed strips. It is apparently less attracted 

 to food than M. domestica.
