products to other localities and from other infested States into 

 Colorado. Details are given of the quarantine measures in force 

 with regard to this pest. 



Miscellaneous pests include : The San Jose scale [Aspidiotus 

 perniciosus] ; Eriophjes pyri (pear-leaf blister mite) ; Aphis sorbi 

 (rosy apple aphis), against which spraying with kerosene emulsion 

 Black-leaf 40 or a good grade miscible oil before the buds open is 

 advocated ; Melanoplus bivitfatus, M. dijferentialis, M. atkintis and 

 M. femur-rubrion, against which a bran mash of 50 lb. of bran, 3 lb. 

 of Paris green or 2 lb. of white arsenic, 1 U.S. gal. of syrup, 10 lemons 

 or oranges and 5 U.S. gals, of water, was sufficient for about 6 acres 

 of land. The beet webworm, Loxosfege sticticalis, may be destroyed 

 by the above poison bran mash or by spraying with 4 lb. of Paris 

 green or 8 lb. of lead arsenate to 100 U.S. gals, of water. 



Parks (T. H). Controlling Army Worm Outbreaks in Ohio. — 



MOdy. Bull. Ohio Agric. Expt. Sta., Wooster, iv, no. 9, September 

 1919, pp. 272-275, 3 figs. [Received 16th January 1920.] 



A severe outbreak of army- worms [Cirphis unipuncta] occurred 

 during June 1919 in Ohio. Rye was chiefly attacked, although 

 wheat, maize, timothy and bluegrass were also damaged. In certain 

 counties the infestation covered an area of 1,200 acres and more. 

 The chief damage was done from about 1st to 20th June. The eggs 

 are laid in masses of 10 to 40 under leaf-sheaths of grasses or in and 

 about litter on the ground. The emerging larvae feed unobserved 

 at first and develop very rapidly. During the day they remain 

 under the soil, but emerge at night to feed voraciously on the leaves 

 and heads of rye. Green succulent straws are frequently cut off about 

 4 to 10 inches above the ground. After about 3 weeks they enter 

 the ground to a depth of 1 to 2 inches for pupation. The adults 

 continue to emerge up to the middle of July, giving rise to the second 

 generation which however never does damage to the same extent 

 as the first, probably because of the extensive migration both of 

 larvae and adults. To destroy the caterpillars, furrows should be 

 made to stop their progress as soon as they begin to migrate. The 

 sides of the furrow should be steep and dusty and it should be renewed 

 every day during the migration period. In addition to this, a poison 

 bran mash consisting of 20 lb. of bran, 1 lb. of Paris green, 2 qts. of 

 syrup, 3 oranges or lemons finely ground and 2| U.S. gals, of water, 

 should be scattered broadcast in the early evening as soon as the 

 caterpillars begin to feed. 



HousER (J. S.). Winter Work in Shade Tree Insect Central.— 



Mthly. Bull. Ohio Agric. Expt. Sta., Wooster, iv, no. 11, 

 November 1919, pp. 345-350, 2 figs. 



In order to deal successfully with pests of shade-trees it is essential 

 that a general working plan be fixed well in advance of the season 

 when the actual work is to be carried out. 



Suggestions are here made to help in the selection of spraying 

 apparatus and materials. By inspection in the autumn and winter it 

 is possible to determine the scope and type of insect control measures 

 likely to be necessary in the following season,
