456 EXPERIMENT STATION RECORD. 



Since it occurs in large numbers only upon cotton, it will be possible in a 

 measure to control it by cultural methods, which include (1) annual pruning, 

 (2) clean culture, and (3) trapping the mature moths. The plants should be 

 severely pruned in the fall in as short a time as possible and all the branches 

 and bolls immediately burned. 



From experiments conducted in 1911, the authors conclude that fall pruning 

 is imperative in order to allow proper development of the plants in the winter 

 mouths when moisture is plentiful. " The increase in yield of fall pruned 

 plants was nearly 46 per cent, the average yield per plant being 1.2 lbs. and 

 0.82 lb. of lint per tree for fall and spring prunings during the second year's 

 growth of the plants." An improvised lantern trap recommended for use is 

 illustrated and described. 



Bag'-shelter caterpillars of the family Liparidae that are reputed to kill 

 stock, W. W. Froggatt (Agr. Gaz. N. S. Wales, 22 (1011), No. 5, pp. U3-W, 

 pis. 2). — It is stated that when horses are fed on pastures which swarm with 

 the slender hairy caterpillars of Ocinara Icwince, the hairs coming in contact 

 with the mucous membrane of the mouth cause an ulceration which sometimes 

 even results fatally. 



March flies, W. W. Fbogoatt (Dept. Agr. N. S. Wales Sci. Bui. 3, 1911, pp. 

 16, pi. 1). — This is a brief account of the moi'e important species of Tabanidse, 

 together with a list of 109 that have been recorded from Australia and Tas- 

 mania. 



The dying of pine in the Southern States: Cause, extent, and remedy, 

 A. D. Hopkins (U. /S'. Dept. Agr., Farmers' Bui. Jf76, pp. 15, figs. J/). — This 

 bulletin consists of a series of revised circular letters which were used in 1911 

 in an active campaign by the Bureau of Entomology of this Department 

 through a forest-insect field station, located at Spartanburg, S. C, the purpose 

 of which was to study the character and extent of the dying pine and to give 

 instructions and demonstrations to the owners within the worst affected areas 

 on the most economical and effectual means of control. 



It is stated that in the areas designated as the shortleaf pine and loblolly 

 pine belts, as well as in parts of the longleaf pine belt, the death of the pine 

 has been caused by the southern pine beetle (Dendroctonus frontalis), while 

 in Florida and certain other sections it is apparently due to a combination of 

 other but similar bark-boring beetles. An account by the author of the life 

 history and habits of D. frontalis, which was flr.st described in 1868 from speci- 

 mens collected in North and South Carolina, has been previously noted from 

 another source (E. S. R., 22, p. 157.) 



" Extended observations in all of the Southern States during the past 20 

 years led the writer to conclude that if all of the pine that has been killed 

 during this time by this beetle was living to-day its stumpage value would 

 amount to from $10,000,000 to $20,000,000 or more. ... It is also evident 

 that if active steps are not taken this winter by the principal owners in the 

 infested areas this loss will be increased to another million dollars within the 

 next year." 



A description is given of the more important evidences of the presence and 

 work of this beetle, directions for locating infested trees, together with the 

 essential details in methods of control, and i-equirements for success. The 

 method of control consists in locating the infested trees during November, 

 December, January. February, and March and destroying the overwintering 

 broods in the bark of the main trunks in the manner herein described in detail.
