A summarized account of The Cabbage Root Maggot, by Q. S. Lowry (pp. 

 142-152), is followed by a report on Field Experiments in Controlling the Cab- 

 bage Root Maggot in 1914, by W. E. Britton and Q. S. Lowry (pp. 152-157). 

 The results indicate that tarred paper disks and carbolic acid emulsion are 

 about equally effective in preventing damage from maggots and that sludge 

 (residue from the manufacture of lime-sulphur mixture) is fairly satisfactory. 

 In a discussion of the Outbreak of the Army Worm (pp. 157-173) the author 

 presents a summarized account of the pest with a list of the more important 

 literature relating to it. Experiments in Controlling the White Pine Weevil 

 are described by B. H. Walden (pp. 173-176). The pest continues to do much 

 damage to white pine plantations in the State. Experiments made in con- 

 trolling the pest by collecting the weevils on pine leaders with a net indicate 

 that at least six collections may be made at an expense not to exceed $1.50 to $2 

 per acre. In work at Portland and Rainbow in which four and five collections 

 were made, respectively, the percentage of injured leaders where the net was 

 used was less than half the percentage of those injured on the checks. Experi- 

 ments in Controlling a Mite (Tarsonemus palUdus) Injuring Snapdragon Plants 

 in the Greenhouse are reported by W. E. Britton, B. H. Walden, and Q. S. 

 Lowry (pp. 176-179). In addition to snapdragon, the leaves of which were 

 badly curled and the entire season's crop threatened as a result of attacks by 

 this mite, chrysanthemum and cyclamen were also injured. The tests indicate 

 that blackleaf 40, used at the rate of one teaspoouful to a gallon of water 

 with the addition of soap and "Fir-tree Oil" (4 to 6 oz. in 2 gal. of water) 

 will control this mite on snapdragon if four applications in the form of a spray 

 are made at intervals of about a week. A Tent Caterpillar Egg Contest (pp. 

 179, 180), arranged for school children, is briefly described, as is Mosquito 

 Work in Connecticut in 1914 (pp. 1S1-1S3). Caterpillars of a noctuid moth 

 (Hadcna ttirhulenta) are reported to have attacked wild smilax or "green- 

 briar" (Sniilax rotunclifolia) at Kidds Island, off Stony Creek, Branford. 

 Tests made of a commercial preparation, known as " Corbin," to protect seed 

 corn, show that it reduces the percentage of germination and retards develop- 

 ment, where the vitality is not impaired, to such extent that its value is ques- 

 tionable. 



The report concludes with a discussion of miscellaneous Insect pests, includ- 

 ing pink grasshoppers (Scudderia fiircata), Polygonia interrogationis on elm. 

 cherry or pear slug (Caliroa limacina), two rare lady beetles {Harmonia similis 

 and Anisocalvia 12-maciiIaia), the tulip tree scale {TowncycUa Uviodendri) , the 

 strawberry white fly (AsterocMton [Aleyrodes] packardi), the chinch bug, the 

 saddle-back caterpillar, the hickory leaf stem gall louse (PhyUoxcra cary- 

 cccauUs), injury by bill bugs {Sphenophorus sctilptilis), the four-lined leaf bug 

 (Poecilocapsus Uneatus), the grape plume moth, the Colorado potato beetle and 

 zinc arsenite, pupiG of Macrosargus cuprarhis, the walnut cateiiMllar (Datana 

 integerrima) , leaf hopper (Oypona flavilineata) injuring Japanese barberry, 

 controlling green apple aphis, mites on California privet, harlequin cabbage 

 bug in Connecticut, European pine shoot moth {Evetria dnoliana), the oak 

 pruner {EUipliidion villosum), pear psylla. the stalk borer, injury to geraniums 

 by white ants (Termes flavipes), false apple red bug in Connecticut (Lygidea 

 mcndax), and the hickory bark borer {Scolytus quadrispinosus) . 



Report of entomologist, J. R. Watson {Florida Sta. Rpt. 19U, pp. XLVI- 

 LVI).—A brief account is given of entomogenous fungi, studies of which by 

 Rolfs have been previously noted (E. S. R., .30, p. 55), and of the occurrence 

 of white fly fungi in observation groves. Experiments with sprays in the con- 

 trol of the Anticarsia caterpillar on velvet beans, commenced in 1912, were
