The cabbage maggot and other injurious insects of 1906, F. L. Washburn 

 {JiJiiuK'fiota tSlii. Bill. JOO, PI). (S'7. /</.y. 7. figs. J7). — The material contaiued in 

 this bulletin has already been noted from another source (K. S. R.. 18, p. 749). 



The oriental moth, a recent importation, H. T. Fernald {Massachusetts 8ta. 

 Bui. 114, PP- 14, pJ- 1, Pii- !)• — Kai'ly iu 190G cocoons were found on several 

 kinds of fruit trees in Dorchester, Massachusetts, which subsequently proved 

 to be Cnidocatnpa flavesceiis. This insect was most abundant near a locality 

 where a Japanese nursery had previously been maintained aud has become dis- 

 tributed to a distance of 2 miles in one direction and nearly IJ miles in the 

 other. The pest occurs on Norway maple, as well as other kinds of maple, and 

 also on pear, apple, cherry, and crab-apple trees, and various species of forest 

 trees. As many as 100 cocoons have been found on a single tree. 



The oriental moth was apparently introduced before 1900. There is one brood 

 annually, and the moths appear in June and July. The insect is described iu 

 all its stages. It has a wide distribution iu the- Orient aud could probably 

 thrive in almost any part of the United States. It is still doubtful whether it 

 will prove a serious pest. 



Preliminary report on cranberry insects, II. J. Franklin (Massachusetts 

 t^ta. Bui. 115, pp. 15). — A careful study was made of the remedies best adapted 

 for controlling the chief insect enemies of the cranl^erry. 



For the cranberry fruit worm on bogs which have an abundant water supply 

 the author reconnnends flooding immediatel.v after picking and drawing oft' 

 the winter flowage early in April. On bogs with a limited water supply It is 

 recommended that the winter flowage be turned on as soon as possible after 

 the cranberry foliage has ripened. Arsenate of lead must be used as a spray 

 on bogs which do not admit of flooding with water in winter. 



In treating the fireworm on bogs with a good water supply, the winter 

 flowage may be drawn off about the middle of April and the worms, which 

 normally hatch after this period, may be destroyed by spraying with arsenate 

 of lead. 



If the false army worm appears in large numbers, it is desirable to reflow 

 the cranberry bogs for 24 to '.MS hours soon after May 1.5. This may be repeated 

 if necessary. Dry bogs should be sprayed with arsenate of lead early in May. 



The yellowhead cranberry worm may be controlled liy holding on the winter 

 flowage until after May 20 or by spraying dry bogs with arsenate of lead about 

 May 15 and July 4. 



A brief account is also given of methods of treatment for the cranberry girdler 

 and spittle insects. 



Poisoned bait for the fruit fly, T. F. Dreyer {Agr. Jour. Cape Good Hope. 

 30 {1901), No. 2, pp. 192-19-',). — A formula has already been suggested by Ber- 

 lese for the preparation of a poisoned bait for killing the fruit fly, this bait 

 consisting of 31 i)er cent of honey, 05 per cent of molasses. 2 per cent of glycerin, 

 and 2 per cent of arsenite of ])otash. While it is believed that this formula 

 would be of service in South Africa, another is suggested calling for 1 lb. of 

 arsenate of lead and ;"> gal. of sirup in 25 gal. of water. 



Treatment for the olive fly, G. Battanchon {Prog. Agr. ct ]'it. {Ed. I'Est), 

 28 {1907), JSio. 9, pp. 264-266). — Arsenical treatments are admitted to have 

 given good X'esults in the treatment of the olive fly, but the author seems to 

 recognize the prejudice against the use of arsenic on olives, and suggests that 

 the innnediate collection of all infested olives which fall from trees and the 

 disinfection of storehouses where olives are kept might yield satisfactory results. 



A viviparous fly with larvae sometimes parasitic and sometimes vege- 

 tarian, J. K. d'Herculais {Vompt. Rend. Acad. IScL [Paris], 144 (1907), No.
