The mixture recommended by both Taschenberg and Hollrung, 

 containing five parts resin, two parts lard, two parts stearin oil and one 

 part Venetian turpentine, proved useless against C. brumata, as it 

 became liquid on the sunny side of the tree-trunks and on the shady 

 side formed a skin over which the females were able to crawl. Many 

 writers, including Taschenberg and Kirchner, have recommended a 

 mixture of five parts rape-seed oil, one part lard, one part turpentine, 

 and one part colophony. This proved very sticky, but too Uquid. 

 Kirchner also advised a mixture of seven parts wood-tar, five parts 

 colophony, five parts brown soap and three parts fish oil, but this is not 

 efficacious in the case of 0. brumata as it forms a dry skin. Contrary 

 to what is stated in text-books, a mixture of equal parts of colophony 

 and linseed oil is absolutely useless. Both coal-tar and the more 

 costly wood-tar are too liquid, and soon lose their adhesiveness if 

 mixed with resin. A mixture of six parts fir-resin, five parts stearin 

 oil and four parts lard also proved inefficient. A home-made adhesive is 

 therefore not advisable and where the American product is unobtainable, 

 it is best to use the commercial black banding adhesive. This must 

 be renewed more often than the American one.
