 Pennsylvania Dept. Agric, Uarrishurg, no. 318, Slat May 1915. 



Carpets attacked by the buffalo carpet beetle [Anthrenus scrophu- 

 lariae] should be exposed to air and suidight for some hours, and the 

 floors washed with 3 per cent, solution of creolin. After replacing 

 the carpets, the edges should be sprayed with a dilute solution of 

 corrosive sublimate in alcohol or water [see this Review, Ser. A. iii, 

 p. 184].

Fur and woollen materials can be successfully preserved from 

 attacks of moths by placing in a galvanised iron box with a well- 

 fitting lid, together with a shallow dish containing a small quantity 

 of carbon bisulphide. The box should not be opened for at least two 

 or three days after treatment. The carbon bisulphide should be 

 renewed about three weeks later and again at longer intervals if 

 necessary. 



McAtee (W. L.). Bird Enemies of Forest Insects. — American Forestry, 

 Washington, D.C., xxi, no. 6, June 1915, pp. 681-691, 12 ^gs. 



Birds are the most important of the natural enemies of forest insects 

 and more than 45 species are known to feed on bark beetles. The 

 larvae of the round-headed and flat-headed wood-borers are destroyed 

 by woodpeckers. The leopard moth, a pest of shade trees, is held in 

 check by several native birds. The red-shafted flicker, pileated wood- 

 pecker and the nighthawk are specially destructive to carpenter-ants. 

 The absence of forest tent-caterpillars in some localities has been 

 correlated with the abundance of bird enemies. In California, the 

 brewer blackbird has on several occasions freed the orchards from 

 canker-worm. The English sparrow was introduced into America 

 for the purpose of suppressing the linden moth and, in England, the 

 attraction of birds has been adopted as a definite method of combating 

 the larch sawfly. 



Advice for the Month of June. — American Forestry, Washington, B.C., 

 xxi, no. 6, June 1915, pp. 717-718. 



The nests of forest tent caterpillars \Malacosoma disslria] on wild 

 cherry, mulberry, willow, etc., should be destroyed by applying a 

 burning rag or torch to the web or by squirting a little kerosene into it. 

 Leaf-eating insects should be sprayed with lead arsenate, at the rate 

 of 1 lb. to 10 U.S. gals, water. Hickory trees infested with the hickory 

 bark borer [Scolytus quadrispinosus] should be removed and destroyed 

 before the emergence of the adults in June. The presence of the 

 insect can be detected by small holes in the bark and the fine sawdust 

 ejected from these. In the vicinity of New York City, including all 

 Long Island, parts of New Jersey and Westchester county, hickory 

 trees are badly infested with this pest.
