160 EXPEEIMENT STATION RECORD. 



infosted bouses, treat dogs regularly for fleas, and apply insecticides such as 

 bubach, hot soap suds in dwelling bouses, etc. 



The iutroduction of top minnow for the control of mosquitoes was success- 

 fully accomplished and these fish seem to be serving as an efficient aid in the 

 control of mosquitoes. Apicultural work of the station included a study of 

 Hawaiian honeys and the problem of largely increasing the production of wax. 

 The latter under favorable circumstances is a nuicb more profitable crop thau 

 honey. F<)ul brood has not yet been introduced into Hawaii, lieconunendations 

 were made in regard to the encouragement of silk culture by allowing the labor- 

 ing population on plantations to have small areas for mulberries and sericul- 

 tural work. 



Additions made to the list of injurious insects thus far reported from Hawaii 

 are presented as are also the accessions of books and periodicals relating to 

 Hawaiian entomology. 



Report of the entomologist, H. Tryon {Ann. Rpt. Dept. Agr. and Stock 

 [Qiivcnshind], 1906-1, pp. 7S-S1). — During the year observations were made on 

 the insect pests of sugar cane, corn, cotton, alfalfa, citrus and other fruits, and 

 garden vegetables. A brief report is also made on cattle ticks and on the 

 movement for the protection of native birds. 



Report of government entomologist, 1906, H. C. Pratt iA[/r. Bui. Straits 

 and Fed. Malay States, 6 (1907), No. 9, pp. 303-308). — Notes are given on the 

 habits and life history of Nonagria inferens and Leptocorisa acuta which 

 caused injury to rice and also on some unidentified insects which seriously 

 defoliated cocoanut trees. 



Indian insect pests, H. M. Lefeoy (Calcutta: Govt., 1906, pp. XI I +318, figs. 

 SG.'i). — The present volume on the insects of India is written not so much as 

 a treatise for the scientific entomologist as for the farmer. The chief insect 

 pests with which the Indian farmer has to contend are described and notes are 

 given on their life history and habits. Most of these pests are illustrated. The 

 volume contains a general account of insect anatomy and their habits, insecti- 

 cides, and special sections on the more important insect pests of cotton, rice, 

 wheat, sugar cane, corn, leguminous crops, miscellaneous garden crops, and 

 fruits, and the insects affecting cattle. In an appendix to the volume informa- 

 tion is furnished rfgarding the cost, preparation, and application of insecticides. 



The life history of the carpenter ant, J. L. Priceb (Biol. Bui. Mar. Biol. 

 Lah. ^Yoods Holl, 1.', (1908), Xo. 3, pp. ^77-2 17, figs. 6).— The author made a 

 study of two varieties of Cumponotus hercvlancus. Particular attention was 

 given to the life history of the colony, polymorphism observed in individuals, 

 division of labor, the food, relations to light and color, and the instincts of the 

 insect. It is suggested that some of the injuries to wood which have been 

 attributed to this ant are not due primarily to the ant, but rather to other 

 insects which first produced the burrows in the wood in which the ants subse- 

 quently came to live. 



An automatic trap for night-flying moths, J. Friedrich (CentN. Gcsani. 

 Forstir., S.'i (1908), Xo. 1, pp. l-'i, figs. 3). — In connection with illustrations an 

 apparatus is described for the capture of night-flying moths. The apparatus 

 consists essentially of a revolving drum moved by clockwork and illuminated 

 by means of a lamp on the inside. The moths attracted by the light rest upon 

 the drum and are brushed off into a receptacle during the revolution of the 

 drum. The author reports that tests thus far made with this machine indicate 

 that it is very eft'ective. 



The control of snout beetles on beets, B. Wahl and K. Philp (Wiener 

 Laitdw. 7Ag., 58 (1908), Xo. 1, pp. 3, .'/, figs. 2). — A brief account is presented 

 of the life history and habits of Cleonus punctiventris and C. sulcirostris. In
