as one of the worst fruit pests of the year. E. padi, Nal. (plum gall 

 mite), distorted plum leaves in Eastern Montana ; spraying experiments 

 for controlling plum diseases, carried on by the station botanists, inci- 

 dentally demonstrated that this mite can be controlled by a thorough 

 dormant spraying with lime-sulphur. Reports of damage by grass- 

 hoppers w^ere fewer than for several years, but lucerne grown for seed 

 suffered from them. The work of Liothrips montanus, Hood (currant 

 thrips) [see this Review, Ser. A, ii, p. 380], has been noticed for 

 several years. A predaceous bug, Reduviolus ferus, L., was several 

 times observed feeding on the autumn migrants of Pemphigus betae, 

 Doane (sugar-beet root-louse) ; irrigation, by keeping the soil con- 

 tinually moist, not only reduces the number of aphids, but increases 

 both the tonnage and sugar content of the beets. In one locahty 

 maize and potatoes were seriously injured by the Jassid, Oncometopia 

 lateralis, the insects being clustered about the stem of the plant. 

 Aphis brassicae, L. (cabbage aphis), was very abundant, but A. pomi, 

 De G., although common in all apple-growing sections of the State, 

 was not so prevalent as in 1913. Although enormous numbers of the 

 moths of Phlyctaenodes (Loxostege) sticticalis, L. (sugar-beet web worm), 

 appeared in June, the injury was considerably less than for several 

 years past. Numerous complaints of cutworms were received, and 

 Eastern Montana suffered most, an invasion of Euxoa (Chorizagrotis) 

 agrestis, Grote (army cutworm), in several instances destroying entire 

 fields of grain and flax. Pieris rapae, L. (imported cabbage worm), 

 was exceptionally abundant, and some injury was done by Alsophila 

 pomelaria, Harris (fall canker worm), which is apparently spreading. 

 A particularly bad infestation of clothes-moths [Tinea pellionella, L.) 

 was discovered in stored wool samples. Larvae were found in abundance 

 and at work in February, although it is often stated that in the 

 northern States they are not active during winter ; the wool was saved 

 by a thorough fumigation with hydrocyanic-acid gas. The larvae of 

 Samia gloveri, Strecker, were abundant on box-elder, elm, willow, etc. 

 Maggots of fimgus gnats belonging to the genus Sciara were reported 

 as being extremely injurious to the roots of potted plants. Hylemyia 

 antiqua {Pegomyia ceparum) (onion maggot) was reported from 

 several localities, but in Bozeman was not as injurious as in 1913. 

 Adults of Tipida angustipennis (smoky crane fly), were observed in 

 great abundance during April and May. Epochra canadensis, Lw. 

 (currant fruit-fly), continues to injure currants seriously ; experiments 

 were conducted with a poisoned bait, but while the injury was 

 considerably lessened, complete control was by no means effected. 

 Data were obtained which indicate that Pseudanthonomus validus, 

 Dietz (currant fruit weevil) [see this Revieiv, Ser. A, ii, p. 380], is 

 probably two-brooded. A large acreage of winter wheat presented 

 a condition which for w^ant of a better name was called " yellow 

 wheat." In some cases wureworms were found upon the roots of 

 affected plants, but a fungus was also present, and it is therefore 

 difficult to decide the actual cause. Wireworms were also found 

 injuring maize and potatoes. As a result of strict quarantine, the 

 alfalfa weevil is not yet present in Montana. Attention is called 

 to the need for an ordinance deahng with foul-brood in order that 

 protection may be given to the bee industry in Montana, which annually 

 produces about 1,000,000 lb. of honey.
