158 EXPERIMENT STATION RECORD, 



In these experiments it was found tliat all of the lime-sulphur combiuations 

 were almost equally effective. It appears to l)e possible, therefore, to allow a 

 relatively wide range in the proportions of the ingredients of this wash. In 

 general, however, the author prefers a formula calling for 20 lbs. lime and 15 

 lbs. sulphur per 50 gal. water with a boiling period of at least 30 minutes. The 

 2 other formulas especially recommended contain the same amount of lime and 

 sulphur and 4 to lbs. caustic soda or 10 11)S. washing soda. 



Brief notes are given on various insects which caused more or less damage 

 during the year. These include fruit-tree bark-beetle, apple-leaf miners, tussock 

 moth, fall webworm, violet sawtly, buffalo tree hopper, pea louse, larder beetle, 

 etc. Another attempt to establish Ohilocorus similis: appeared to be unsuccess- 

 ful. The voluntary entomological service of the State is briefly described and 

 a list of publications by the entomologist is presented together with a catalogue 

 of contributions to the collection of insects. 



Considerable attention was given to mosquitoes. A table is presented for the 

 identification of mosiiuito larvae, several new species are described, and notes 

 are given on their life history. Notes are also given on the life history, habits, 

 and distribution of the g.vpsy moth and the brown-tail moth. 



H. Osborn rnade a study of the Jassid?e of. New York State, and presents a 

 discussion of these insects based on a list of 175 species found in the State 

 (pp. 498-545). A list of Lepidoptera taken at Keene Valley. New York, is pre- 

 sented by G. F. Comstock. 



Report of the entomologist, J. Fletcher ( Canada Expt. Fauns Rpts. 1905, 

 pp. 159-200, pi. 1). — During the year under report the Hessian fly was not par- 

 ticularly injurious. Some observations were made on the insect parasites of 

 this pest. In ]ManitoI)a and the Northwest Territories the western wheat-stem 

 sawfly caused some injury, and complaints were also made regarding joint 

 worm, wheat midge, and cutworms in cereals. The method of using poisoned 

 bran in the control of these pests is very satisfactory. It is stated that the 

 Griddle mixture still proves effective when used against locusts. Notes are 

 also given on bee moth, rose chafer, stalk borer, boUworm, variegated cut- 

 worm, carrot rustfly, cucumber beetle, sugar-beet webworm, San Jose scale, 

 codling moth, woolly aphis, apple maggot, strawberry weevil, Otiorrhynclius 

 ovatus, larch sawfly, spruce gall louse, Tussock moth, Therina somniaria, etc. 



A report of the work of the apiary for the season of 1905 was made by J. 

 Fixter (pp. 194-200). Successful attempts were made to prevent swarming 

 by offering more room for brood comb and honey production. Attention is 

 called to the desirability of keeping a close watch on the annual production of 

 each colony of bees in order to improve the productiveness of the whole apiary. 

 It is believed that in this way tlie amount of honey production may be consider- 

 ably increased. The use of queen cells in small nuclei is explained as a system 

 of queen rearing. In the case of infestation of combs by the bee moth, these 

 pests may be destroyed l)y a fumigation with sulphur. 



On some injurious insects in 1905, K. S. Macdougall {Trans. Highland and 

 Agr. Soc. Scot., 5, ser.. IS iVJOii), pp. 22^-237, figs. 23).— Notes are given on a 

 ruimber of insects injurious to garden crops and forest trees. These pests 

 include Ceuthorhynchus sulcicoUis, C. assimilis, and C. contractus attacking 

 cabbage and turnip, pea and bean weevils, carrot fly, turnip flea-beetle, grain 

 weevil, diamond-back moth, crane flies, pine weevils, pine sawfly, goat moth, etc. 



The remedy recommended for the cabbage and turnip weevils consists in 

 soaking the seed for 4 hours in turpentine or kerosene. The carrot fly may be 

 largel.v controlled by spraying with kerosene emulsion after sowing, again after 

 germination, and a third time after thinning the carrots.
