In controlling tlio insect pests of cranberries, tioodinj;; is recommenclecl for 

 the first brood of the r)]iickheaded or yeilowheaded vine worm. Spraying is a 

 safer but more lalidridus method of control. Two applications are snfficient for 

 vine worms and tln«'e for frnit worms. The spray recommended for this pur- 

 pose is lead arsenate solid ion and Bordeaux mixture with 5 lbs. of resiu soap 

 added for each .".(» gal. Arsenate of lead is con.sidered superior to Paris green. 



Report on the work of the section for plant protection, 1906-7, C. P.rick 

 (Stat. I'flaiizcitschutz llnnibunj. Hot. Stdutinst., [lici:\ Aht. I'flaiizciiscliut::, 

 {1906-7), pp. J-IS). — A detailed report is given of the extent of importation 

 of apples and other fruits and living plants from America and other countries. 



As in previous years the P>aldwin is the chief apple imported from the 

 United States, constituting alxmt 70 per cent of the total importation and 

 conung chiefly from New York and Maine. From a total of about 200,000 

 packages of these apples about 11,000 or approximately 6 per cent were found 

 to he infested with San Jose scale. Apples imported from New South Wales 

 were found to be slightly infested with San Jose scale. Notes are also given 

 on other insect i»ests and plant diseases found upon this fruit. 



A report is also made upon the condition of live plants imported from various 

 countries. 



Does it pay to spray Nebraska apple orchards? U. A. Emerson and F. E. 

 Denny {Nebraska Sta. Bill. 106, pp. S-.IO). — Practical tests were made under 

 what wei-e considered average conditions to determine the value of spraying 

 orchards, particularly for the control of codling moth and apple scab. Five 

 a]iplieations were made from May 2 to August 20 of combined insecticides and 

 fungicides chietiy Paris green or arsenate of lead and Bordeaux mixture. For 

 the first three applicaticms Paris green and Bordeaux mixture were used while 

 arsenate of lead was used alone in tlie last 2 sprayings. In one orchard a net 

 gain of .$1.70 i)er tree was produced and in another orchard of .$2.50, the in- 

 creased yield being 1.17 bu. and 2.1 bu. per tree, respectively. 



The apple maggot or railroad worm. A. L. Quaintance (U. 8. Dept. Agr., 

 Bur. Ent. Circ. 101, pp. 12, p(/s. 2). — The apple maggot is placed among the five 

 chief insect enemies of the apple. It is a native American species and its 

 native food is api)arently si)ecies of Crataegus. It attacks nearly all varieties 

 of cultivated apples. The spread of the apple maggot when once established 

 in the orchard is very slow. The insect is described in all its stages and notes 

 are given on its life history. There is only one generation annually. 



In combating this pest no hope can be entertained of success from the use of 

 arsenicals. All fallen infested fruits should l)e promptly gathered and fed or 

 otherwise destroyed. If iireferred, orchards may be i)astured with sheep, hogs, 

 or cattle to destroy the windfall apples promptly. Some success may also be 

 expected from tlie thorougli cultivation of orchards. 



The insect pests of peach trees, F. Lafont {Prog. Agr. ct Vit., 2-i {1907), 

 A'o. 'i9, pp. 6S0-6S.J). — Biological and economic notes are given on Ceratitin capi- 

 tata, codling moth. Anar.sia UncatcJla, Vossiix ligniiicrda. bark beetles, and other 

 insects injurious to peaches. 



State nursery inspection, J. (J. Moork {Wm-oiisin l^ta. Rpt. 1907, pp. 369-378, 

 figs. 3). — The law go\erning nursery inspection in Wisconsin was so amended 

 in 1907 as to provide for the inspection of the premises of all nurseries doing 

 business within the State. The general conditions observed in the nurseries 

 during the past season were somewhat improved. San Jose scale was found in 

 one nursery only. Mention is also made of the pre\alence of oyster-shell bark- 

 louse, woolly aphis, strawberry root louse, cottony inaple scale, coxcomb gall 

 of the elm, and anthracnose of raspberries.
