 and Plant Diseases. — Univ. Tennessee Agric.Exj)t. Sta., Knoxville, 

 Bull.no. 106, June 1914, 25 pp., 4 figs. [Received 25th May 1915.] 



This bulletin contains suggestions as to the control of insect and 

 fungus pests by cultural methods, beneficial insects, birds, insecticides 

 and fmigicides. A number of formulae are given together with 

 directions for making them up. 



The Pine-Shoot Moth. — Amer. Forestry, Washington, D.C., xxi, no. 5, 

 May 1915, pp. 637-640, 7 figs. 



The importation of pine trees from Europe after 1st July 1915, has 

 been forbidden by the Department of Agriculture under a quarantine 

 order. This action has been taken to protect American pine trees 

 from the pine shoot moth {Rhyacionia buoliana), which is so injurious in 

 Europe, and has been found in a few locaUties in the United States [see 

 this Review, Ser. A, iii, p. 376].

This investigation of the wilt of Lymantria (Porthesia) dispar, L., 

 (gipsy moth) caterpillars was undertaken in the hope of obtaining 

 results of economic importance. The wilt, first recorded in the United 

 States in 1900, is a true infectious disease distributed over the entire 

 infested territory. Epidemics occur only in heavily infested localities. 

 CUmatic conditions appear to bear an important relation to wilt in the 

 field, and it has been shown experimentally that sunlight can convert 

 the chronic into the acute form of wilt. Older caterpillars suffer 

 more than younger ones, but small individuals also die of the disease 

 in the field. Infection naturally takes place through the mouth by 

 means of the food. Some of the imported parasites may be important 

 factors in aiding the dispersion of this disease, which is probably 

 transmitted from one generation of caterpillars to another, although 

 no definite evidence on this point is as yet available. A bibliography 

 of 18 works is given. 



Chittenden (F. H.). The Violet Rove-Beetle.— Z7. S. Dept. Agric, 

 Washington, D.C., Bull. no. 264, 15th June 1915, 4 pp., 1 fig. 



Since 1901, a small dark-coloured rove-beetle, Apocellus sphaericollis. 

 Say, has been reported as an enemy to violets and other succulent 

 ornamental plants in the Di-strict of Columbia and from St. Louis, Mo. 

 The complaints cover a period of 12 years and some of the many 

 records of injuries by ants in greenhouses are probably due to this 

 ins?ct, which closely resembles Tetramorium caeapitum, L. (pavement
