558 EXPERIMENT STATION EECORD. 



Three species of icbneumous {I'wipla inquisitor, P. conquisitor, aud AUo- 

 cota thyridopterigis) are found commonly parasitizing tlie bagworm. The vari- 

 ous small parasites reared from the bagworm from various parts of the State 

 include Hahrocytus thyridopterigis, which is most abundant; Dibrachys 

 bouchcanus, which is also common; and Pteromahis sp., Tctrastichus sp., and 

 Phobctcs aJbiiiopennis, which are less abundant. Limited observations led the 

 author to consider ants an important check upon the young caterpillars. Birds 

 were fonnd to be important enemies. 



Control measures consist (1) of the collection of the bags and (2) of the 

 application of an arsenical. When collected all the female bags containing eggs 

 should be placed in a box or barrel far from trees or shrubs, since this will 

 render it impossible for the young caterpillars upon hatching to find their way 

 to trees and at the same time prevent the destruction of beneficial parasites. 



"As the result of experimental tests of the effect of poison upon bagworms 

 of different ages, the writer finds that the very young caterpillars readily feed 

 upon poisoned foliage and quickly succumb. The older caterpillars are more 

 cautious about feeding upon sprayed foliage. From this it is evident that 

 early spraying is desirable, for it not only proves more effective but also de- 

 stroys the pest before the foliage Is consumed. Arsenate of lead should be 

 used, especially upon evergreens, since it sticks better and is less apt to burn 

 the foliage. If the spraying can be done while the caterpillars are yet small, 

 21 lbs. of arsenate of le^id to 50 gal. of water is sufficient. When later spray- 

 ing is done to control the older caterpillars it is advisable to use from 3 to 5 

 lbs. to 50 gal. of water, though at the latter strength slight burning may occur 

 on evergreens. The first regular application of poison for the codling moth just 

 after the blossoms fall will control the bagworm in orchards. One careful 

 application of poison befoi'e the first of June will completely control the pest 

 either upon fruit, evergreen, or shade trees." 



The fostering and i)rotection of birds is recommended. 



Butterfly hunting' in many lands, G. R. Longstaff {Lomlon, 'Sew York, 

 Bombay, and Calcutta, 1912, pp. XYIII+12S, pis. 76).— This work deals with 

 the occurrence, bionomics, etc., of various Lepidoptera and other insects, based 

 upon observations made in Asia, Africa, New Zealand, Australia, North Amer- 

 ica, South America, and the West Indies. A series of papers by P. Miiller deal- 

 ing with the scent organs, etc., of Lepidoptera, translatetl from the German and 

 Portuguese by E. A. Elliott, are presented in appendixes. 



The brown-tail moth in New Brunswick, W. :McIntosii (Rpt. Agr. New 

 BruHsivick, Wll, pp. 2S2-236, pi. 1). — A brief account is given of the work of 

 combating in New Brunswick the brown-tail moth. i\n egg cluster of which was 

 first found at Old Ridge near St. Stephen in the sunmier of 1910. An account 

 of preventive work conducted in New Brunswick is appended. 



The grapevine scrawler or wi-iter (Bromius vitis), F. Picaud (Prog. Agr. 

 et Vit. [Ed: VEst Centre'], 32 {1911), No. 23, pp. 105-109, pi. 1)..—A brief ac- 

 count of a chrysomelid beetle (B. vitis) which attacks the grape, its habits and 

 injury, and remedial measures therefor. This beetle is said to reproduce 

 parthenogenetically. 



A new pest of cowpeas (Agr. Xrics [Barbados], 11 (1912). No. 267. p. 23'/). — 

 A lepidopterous insect which in October, 1911, caused a considerable amount 

 of injury to cowpeas growing in a field near Bridgetown, Barbados, has been 

 found by H. G. Dyar to represent a new genus and species, to which the name 

 BaUovia cistipennis has been given. It is said that an insect causing similar 

 injury to the horse bean (Canavalia cnsiformis) occurs in St. Kitts, but up to 

 the present time the adult has not been reared.
