Argyresthia certella is usually obtained from infested spruce buds, 

 the injury being confined to the bud ; where this extends |— f^ of an 

 inch along the shoot A. glabratella is the species concerned.

Limothrips cerealium caused white-ear disease in cereals to a 

 serious extent. Kainit was successfully used against Otiorrhynchns 

 sulcatus infesting vines, about 7 oz. being placed during the dead 

 season in hollows around each stock.

Scale-insects were abundant on plum trees, which were also attacked 

 by Otiorrhynchus ligustici and ColeopJiora sp. 



No success attended an attempt to transfer Tetraneura ulmi from 

 Ulmus montana major dampieri wedrei to U. atropurpurea, though at 

 the same time the Tetraneura galls typical to U. atropurpurea developed 

 in some numbers. In the case of the transfer of T. uhni to U. pendula 

 there occur galls which differ in shape from those on U. dampieri 

 wedrei and which do not develop fully. Failure met every attempt to 

 transfer the stem-mothers of Eriosoma (Schizoneura), which are much 

 more mobile than those of Tetraneura.

The most important pest of rape in Mecklenburg is Meligethes 

 aeneus. After hibernating it appears at the end of April or early in 

 May. The larvae appear 8-10 days after the eggs are laid ; after one 

 month they pupate in the ground, and 12-16 days later the adult 

 emerges. Other Coleopterous pests discussed in this paper are 

 Ceuthorrhynchus spp., Baris chlorizans, and Psylliodes chrysocephalus. 

 Lepidopterous pests of rape in Mecklenburg are Agrotis segetum, 

 Pieris napi, Evergestis extimalis and Phalonia (Conchylis) epilinana. 

 Athalia colibri {spinarum) is not yet abmidant in Mecklenburg. The 

 cabbage gall-midge, Perrisia {Dasyneura) brassicae, also occurred.
