inspection. The author also discusses orchard spraying and presents a short 

 entomological calendar. Notes are given on the life history and means of com- 

 bating a number of injurious insects, including cottony maple scale, soft plum 

 scale, army woi-ui. cutwoi-ms, stalk lK)rer, household insects, and white grubs. 



Some insects of orchard and other fruits, (". F. Adams {Arkansd.s Htn. Bill. 

 iKi, PI)- it. /il/x- .-'/). ^Bricf biological and economic notes are given on codling 

 moth, San JosC' scale, apple-twig borer, flat-headed apple borer, buffalo tree 

 hopper, twig girdler, woolly aphis, pear-tree slug, plum gouger, plum curculio. 

 peach borer, peach twig borer, blackberry crown borer, strawberry weevil, etc. 



Report -of the division of entomology, R. C. L. Perkins {Hun-aikin ^ngar 

 Phniters' Hta. Jipt. J90G. pp. J/S-oO). — A brief statement is made regarding the 

 work of the traveling entomologists, the distribution of beneficial insects in 

 Hawaii, the insjjection of plantations, and miscellaneous entomological work. 



Problems in economic entomology in the Philippines, C. H. K.vnks {Philip- 

 pine .lour. ,s'c/.. / (inoi;). Yo. 10. pp. /06'7-/^y7'/).— Attenti<m is called to some 

 of the economic problems which have arisen in the study of insects in the Phil- 

 ippines. It is believed that special attentiim must be given to locusts, rice 

 insects, white ants, insects affecting domestic animals, pests of sugar cane, sor- 

 ghum, tobacco, and forests, and to the study of silkworms and bees. 



Entomological notes, J. M. TIayman (/?/>/. Cinnipore [Itidia} Agr. <S7a., 

 JiKPl, pp. ,li. ,i.it. — A pod borer is reported as causing considerable damage every 

 year to chick-peas. The larviP appear first on the leaves and might be con- 

 trolled by arsenical sprays ai)plied at that time. Brief notes are also given on 

 a sjtecies of (Vcidomyia found on wheat. 



Biological division, C. M. G. Johnston (Orain/c River Colonij Dept. Agr., 

 Anil. Rpf.. 2 (l!lO:,-(;). pp. 2'i3-259. figs. 10). — Attention has been given to the 

 destruction of locusts by spraying and the use of poisoned baits as well as by 

 other methods. Mention is made of the insect parasites of the migratory 



ItlCUSt. 



Notes are also given on insects injurious to stock and orchard, garden, and 

 field crops, including ticks, bollworm, cutworms, and potato tuber moth. A 

 brief description is included of certain plants which ai"e supposed to be poison- 

 ous to stock. 



The pests of sugar beets in Bohemia in 1905, H. Uzel {Ztschr. ZucJcer- 

 iiidiis. Bohiiicii. 31 (1901). Xo. .'/. pp. 211-225. fig. 1) . — A list is given of a con- 

 siderable number of insects which attack sugar beets, and ffrief mention is 

 made of the injury to sugar beets by nematodes and parasitic fungi. 



The boll weevil, C. W. Flynn, Jr. {Crop Pest Com. La. Cire. 11, pp. 19, 

 figs. 2). — In cooperation with the Bureau of Entomology of this Department a 

 number of cultural experiments were carried out in different sections of the 

 cotton belt, during which it appeared that Triumph cotton is the best variety 

 for use in sections infested with the boll weevil. Northern-grown seed, in oi'der 

 to retain its early maturing qualities, must be renewed from its northern sources 

 at least every other year. The results obtained from these experiments confirm 

 previous work along this line, and the author therefore recommends thorough 

 preparation of the soil, early planting, the use of early varieties of cotton, 

 abundant fertilizers, thorough cultivation of the crop, and the destruction of 

 cotton plants in the fall. 



Hibernation and development of the cotton-boll weevil, E. D. Sanderson 

 {U. 8. Dept. Agr., Bur. But. Bill. 63, pt. 1, pp. 1-3S, figs. 6).— Since many cotton- 

 boll weevils die during hibernation, it was thought wise to study the effects 

 of various conditions during hibernation upon the mortality of the weevil. It 

 appears that the weevils can not be forced into hibernation until the mean 

 average temperature drops below 60° F. If, therefore, the weevils are deprived
