858 EXPERIMENT STATION RECORD. 



Another migratory moth, J. R. Watson (Ent. News, 26 {1915), No. 9, pp. 

 419--/f22). — This article relates to the noctuid moth Anticarsia gemmatiUs, the 

 caterpillars of which are great pests of the velvet bean and also attack the 

 kudzu vine and horse bean in Florida. 



It appears that the damage to the velvet bean in the Miami section begins in 

 July, at least six weeks earlier than at Gainesville, which is near the northern 

 limit of its occurrence in the larval stage. Records show the migration of the 

 adult to the Northern States to be somewhat similar to that of the cotton leaf 

 worm. It is thought to be quite certain that it does not ordinarily winter over 

 even in central Florida but works northward from the southern part of the 

 State. 



Some notes on the activities of egg parasites of the codling moth in 

 Turkestan, N. N. Troitskii (Trudy Pervago Yscross. Si^sda DQiatcl. Prikl. 

 Ent., Kiev, 191S, pp. 1S5-1S9; abs. m Rev. Appl. Ent., S (1915), Ser. A, No. 5, 

 p 241). — Examinations made in 1913 of various orchards in Turkestan led to 

 the discovery of several parasites of the eggs of the codling moth in addition to 

 iPentartliron) Trichogramma carpocapsw. Amongst these N. Kurdftimov has 

 identified the following: T. emhryophagus in Tashkond. T. scmUidU ? 

 {minuttim ?) in Tashkend, and Trichogramma sp. in Ferghana and Samarkand, 

 where T. carpocapsw was absent. 



Poisoned bait for cutworms, E. H. Strickland {Canad. Ent., 1ft (1915), 

 No. 7, pp. 201-20k). — Experimental control work during the past two years with 

 Porosagrotis orthogonia and Euxoa ochrogastcr, and again during the present 

 spring upon a species of Chorizagrotis, have shown shorts to be far more valu- 

 able than bran for use in a poisoned bait. 



Notes on Anopheles production from a malarial survey, H. R. Carter 

 (Amcr. Jour. Trap. Diseases and Prev. Sled., 2 (1915), No. 12, pp. 753-758). — 

 This paper deals with the relation of foul and clear water to breeding different 

 kinds of mosquitoes, season and districts of breeding of Anopheles punciipen- 

 nis, collections of water not producing Anopheles yet showing Anopheles larvae, 

 and complete and incomplete breeding places. 



The role of Anopheles punctipennis in the transmission of malaria, W. V. 

 King (Science, n. ser., 42 (1915), Nos. 109^, pp. 873, 874; 1096, pp. 934, 935).— 

 The author has demonstrated, through feeding experiments, that .1. punctipen- 

 nis is an efficient host for tertian malaria. It is pointed out, however, that this 

 does not necessarily indicate that it is an efficient carrier of other forms of 

 malaria, and that the investigations of Hirschberg indicate that it is not. 



Mosquito eradication and prevention, with special reference to the 

 malaria-bearing or Anopheles mosquito, W. D. Wkightson (Amer. Jour. 

 Trop. Diseases and Prev. Med., 2 (1915), No. 12, pp. 738-752, figs, f?).— Methods 

 of controlling mosquitoes are dealt with. 



A contribution to the life history of the corn-feeding syrphus fly (Meso- 

 gramma polita), C. H. Richardson (Jour. Econ. Ent., 8 (1915), No. 3, pp. 338- 

 342, pi. 1). — The author reports studies made during the course of an infesta- 

 tion by this fly which extended over a considerable portion of 200 acres of 

 sweet corn at Jobstown, N. J., during the summer of 1913. Adults and larvse 

 were found to feed on pollen, but no deleterious effects upon the corn were 

 observed. 



An eastern Chilosla with hairy eyes, R. C. Shannon (Proc. Ent. Soc. Wa^^h., 

 17 (1915), No. 3, p. 168). 



On the reproductive and host habits of Cuterebra and Dermatobia. C. H. T. 

 TowNSEND (Science, n. ser., 42 (1915), No. 1077, pp. 253-255). — Upon dissecting 

 a female specimen of Cuterebra cvniculi the author found the uterus to contain 

 well over 5,000 eggs, and perhaps nearer 10.000.
