456 EXPERIMENT STATION RECORD. 



C. Fuller in a paper on The l'lnj,aie Ixx-ust of Xatal (p]i. 171-174) referred to 

 the work which has been done In Xatal In controlling Avridiinn purpnrifcriim. 

 The best poison for these pests appears to be arsenite of soda at the rate of 

 1 lb. and sugar -i or 5 lbs. per 1.5 gal. of water. 



The feeding habits of Lcpisnia saccharhia were studied by H. Garnian (])]). 

 174-1 70). According to the speaker's experiments the silver-fish does not feed 

 upon starch or sugar, but preferably upon animal products, such as glue used 

 in binding books and in the moiuitiug of photographs. Occasionally silk is 

 attacked by the silver-fish, but this is also an animal product of a nitrogenous 

 nature. 



Twenty-first report of the State entomologist on injurious and other 

 insects of the State of New York, 1905, 111. P. Felt {N. Y. State Miis. Bui. lOJ,, 

 pp. 'iB-lSG, pis. 10. iifjs. JiS). — As is customaiy in these reports, a brief account is 

 l)resented of the general features of entomological work during the season. 



The author has continued to give attention to the grape rootworm, and finds 

 that by the thorough application of arsenicals, combined with tlie use of 

 beetle catchers and with cultivation of the soil to kill the pupte, badly infested 

 A ineyards may be protected until they recover from the attacks of the grape 

 rootworm. In some cases, however, vineyards have practically been ruined by 

 this pest. The insect is more injurious on loose sandy soils than on heavy 

 clay soils. The use of arsenicals alone will ordinarily not give complete 

 satisfaction. 



An account is also presented of outbreaks of the army worm and of the life 

 history and injurious attacks of various species of grass webworms belonging to 

 the genus Crambus. In fighting the San .lose scale, lime-sulpluu' washes were 

 used as prepared according to 11 different formulas. The general results were 

 very similar where external heat was applied in jireparing the wash, but the 

 author prefers a formula calling for 20 lbs. of lime and 15 lbs. of sulphur in 

 50 gal. of water, boiled at least 30 minutes. 



During the season notes were made and are recorded in the report on codling 

 moth, apple maggot, rose beetle, scurfy scale, white grubs, and various insect 

 l>ests of shade and foi'est trees. The shade-tree problem of the State is dis- 

 cussed, with especial reference to the insects which are concerned in injuring 

 these trees. A test was made of the Caucasian bee. This bee appeared to be 

 quite healthy and reasonably gentle, but was not received early enough in the 

 season to give it a fair test. 



The mosquito problems of the State are also mentioned v>ith reference to 

 campaigns of draining and insecticide work against these pests. A number of 

 gall insects are described and notes given on the malformations caused by these 

 insects on various plants. 



Report of State entomologist of Georgia for 1905. The crop pest law of 

 Georgia, K. I. Smith [Ga. Bd. Ent. Bui. 20. pp. 161-l!).i). — During the year 

 under report considerable inspection work was done and entomological infor- 

 mation was also spread through the agency of farmers' institutes. Particular 

 attention is given in this report to a discussion of the most important insect. 

 enemies of peach, apple, pecan, cotton, grain, and garden crops. 



A copy is also given of the croi) pest law of Georgia and of the regulations of 

 the Georgia State Board of Entomology. 



Means of combating grain insects, I. F. Hoffman (lllus. Landic. Ztg., 26 

 (J906). A'o. HO, pp. 690-692. figs. 6).— Notes are given on the habits and 

 injurious attacks of a number of grain insects, particularly the granary weevil. 



In combating these pests the author has had the best success from the use 

 of carbon bisulphid and anilin milk. The carbtm bisulphid proved effective in
