262 EXPERIMENT STATION EECOED. [Vol. 37 



of this European sawfly, which was first discovered In Connecticut in August, 

 1914, as previously noted (E. S. R., 35, p. 53). 



In captivity eggs were laid on five species of five-needle pines, on six species 

 of two-needle pines, and on one species of three-needle pines. As many as 128 

 eggs are deposited by a single female, usually being placed in needles of the 

 previous year's growth, if any are present. 



Notes on the bean weevil (Acanthoscelides [Bruchus] obtectus), J. A. 

 Manter {Jour. Econ. Ent., 10 (1917), A"o. 1, pp. 190-198). — A summarized ac- 

 count of the biology of this pest and means for its control. 



The alfalfa weevil investigation, G. I. Reitvts (Jour. Econ. Ent., 10 (1911). 

 No. 1, pp. 123-131). — In reporting upon the results of investigations of the 

 alfalfa weevil by the Bureau of Entomology of the U. S. Department of Agri- 

 culture, it is stated that five practical control measures have been developed, 

 namely, flooding with sediment, spraying with arsenical poisons, pasturing, har- 

 rowing the stubble, and colonizing with parasites. While none of these measures 

 is entirely perfected and not all are equally valuable, they are all useful and 

 all are in actual use. 



The clover weevil in Iowa, R. L. Websteb (Jour. Econ. Ent., 10 (1917), No. 

 1, p. 225). — Records indicate that the clover weevil (Bypera punctata) occurs 

 all through southern Iowa and probably most of eastern Iowa. 



The plum curculio, W. H. Goodwin (Mo. Bui. Ohio Sta., 2 (1917), No. 4. pp. 

 113-116, figs. 4). — A brief summary of information relating to the curculio. 

 It is stated that during the last three seasons arsenate of lead paste at the rate 

 of 2 to 3 lbs., with 2 : 3 : 50 Bordeaux and 2 lbs. of soft soap, was used success- 

 fully under the author's direction for preventing the injuries caused by the 

 curculio, with no injury to the fruit or foliage. 



Lime as an insecticide, Z. P. Metcalf (Jour. Econ. Ent., 10 (1917), No. 1, 

 pp. 74-78, pis. 2). — This paper relates to work at the North Carolina Experi- 

 ment Station with the bean weevil and cowpea weevil in cowpeas being saved 

 for seed. 



Co\^'peas were treated late in September, 1913. and left until the following 

 spring, when they were examined. Those treated with air-.slaked lime at the 

 rate of one part to four parts of peas gave a germination of 71 per cent; those 

 with air-slaked lime, one part to eight parts of peas, gave a germination of 

 48 per cent; those with crude carbolic acid at the rate of one-half and one pint 

 per bushel gave 21 per cent germination ; tho.se with kerosene at the rate of 

 one-half and one pint per bushel, 21.5 per cent germination ; and those \\ith 

 carbon bisulphid, at from 15 to 30 lbs. to 1,000 cu. ft. of space, 17.5 per cent 

 germination. 



The favorable results obtained with air-slaked lime resulted In the further 

 experiments, here reportetl. These have led to the recommendation that cow- 

 peas be stored in air-slaked lime at tlie rate of one part lime to two parts peas 

 by weight, at least until something cheaper and more effective can be devised 

 for the average farmer. • 



In a discussion of this paper which follows, W. E. Hinds states that in a 

 series of experiments at the Alabama College Station in wliich several varieties 

 of dry cowpeas were submerged in liquid carbon bisulphid for periods ranging 

 approximately from one minute to 1,000 hours, absolutely perfect germination 

 resulted in all cases. Tests made have shown the reported differences in 

 germination to be due to the varying percentage of moisture at the time of the 

 experiment. 



Problems of bee inspection, F. C. Peixett (Jour. Econ. Ent., 10 (1917), 

 No. 1. pp. 200-203). — A discussion of the problems that must be solved by the 

 bee inspector.
