chiefly feeds on Pinus cxcelsa ; it also occurs on Ahies alba and, more 

 rarely, on Pseudotsvga douglasi. G. ferrugineus prefers Pinus sylvestris, 

 but also occurs on P. nigra, P. montana, Picea excelsa, Abies alba, and 

 Larix.

Much existing information on Cecidomyid galls is uncertain or 

 incorrect, as the authors concerned have not bred the insects forming 

 the galls nor observed them over a period of several years. It is not 

 possible to determine a species from the larvae in a gall. A key to 

 the galls formed by Diptera on Carex spp. in Central Europe is given.

In the last few years there has been an increase of Dendrolimus pini 

 and Bupalus piniarius in Brandenburg. Anomahn circumflexum is 

 the only parasite of the former caterpillars known at present.

Of three beetles that are abundant in May at Uskub, two, Homa-

The apple blossom weevil, Anthonomus pomorum, hibernates in the 

 bark of various fruit trees. At the end of March the adults migrate 

 to the top of the trees, where for about 14 days they feed on the buds 

 until ready to pair. Oviposition takes place 2 or 3 weeks afterwards,
