350 EXPERIMENT STATION RECORD. 



Progress of verruga work with Phlebotomus verrucarum, C. H. T. Town- 

 send (Jour. Econ. Ent., 7 (1914), ^'o. 5, pp. 357-367). — This article reports the 

 details of inoculations of laboratory animals, including Cebus capuchinus, 

 Lepus cuniculus, Canis caraiblcus, Cwvia cobaya, and Canis criollus by or with 

 P. verrucarum in physiological salt solution, at the Verruga Laboratory, at 

 Chosica, Peru, and is in continuation of the investigations previously noted 

 (E. S. R., 31, p. 847). 



" Despite repeated and persistent search from July to October, the early 

 stages of the Phlebotomus have not yet been discovered. It has thus not been 

 possible to attempt the rearing or breeding of them for infection experiments. 

 While no doubt this could be accomplished with unlimited facilities, it is not 

 at all necessary to the complete demonstration of the transmission, already 

 secured, and its realization is not warranted by the conditions." 



A bibliography is appended. 



The daffodil fly, Merodon equestris, G. Stocks (In The Daffodil Year Book. 

 London, 1914 •' Roy. Hort. Soc, pp. 50-59, pis. 2). — This is a report of studies 

 of the life history of M. equestris conducted by the author in England. Its life 

 cycle is of two years' duration, the larva carrying on its destructive work from 

 July of one year to February of the second following year, approximately 19 

 months being passed by the immature stages in the bulb. 



Further notes on the breeding of the tachinid fly, parasitic on the cane 

 beetle borer, J. F. Illingwobth (Jour. Econ. Ent., 7' {1914), ^o. 5, pp. 390- 

 398, pi. 1). — In this paper the author describes the means by which he suc- 

 cessfully introduced a tachinid parasite, Ceromasia sphenophori, of (Spheno- 

 phorus) Rhabdocnemis ohscurus from Hawaii into Fiji. Biological notes are 

 included. As many as 570 fully deveIoi>ed eggs have been found by Muir <* in 

 the uterus of a single female, and it is stated that the number of young possible 

 for a fly to produce is upwards of 1,000. The eggs have been found by Muir 

 to hatch while still in the uterus and the larvae to be deposited. 



A note on Bhagoletis pomonella in blueberries, W. C. Woods (Jour. Econ. 

 Ent., 7 (1914), No. 5, pp. 398-400) .—The author records the infestation of the 

 fruit of three species of blueberries, namely, Vaccinium pennsylvaniciim, V. 

 canadense, and V. vacillans, in Washington County, Me., by the apple maggot. 

 When the maggots are small an infested berry can not be distinguished by 

 sight from a sound one, but usually when they have attained a fair size the 

 fruit becomes very much shriveled and shrunken and the pulp red and stringy. 

 In this county an area of 250,000 acres has grown up almost entirely to blue- 

 berries from which the berries are gathered and sold to canneries. 



[Report and minutes of evidence of the Sleeping Sickness Committee] 

 (Sleeping Sickness Com. [Gt. Brit.}, Rpt. 1914, PP- 26; Minutes of Evidence, pp. 

 330). — These contain much data relating to the biology of tsetse flies and their 

 role in the transmission of trypanosomes. 



The bean fly (Agromyza phaseoli), A. Rutherford (Trop. Agr. [Ceylon], 

 42 (1914), No. 5, pp. 4ii-413)- — It is stated that the bean crop in Ceylon is 

 often a complete failure due to the attack of this pest. 



The wheat bulb fly (Hylemyia coarctata), B. Wahl (Monatsh. Landw., 7 

 (1914), No. 3-4, pp. 82-85, figs. 2; Wiener Landw. Ztg., 64 (1914), No. 65, pp. 

 633, 634, figs. 2; ahs. in Rev. Appl. Ent., 2 (1914), Ser. A, No. 7, pp. 475, 476).— 

 This fly, known as the " Getreideblumenfliege," is a source of injury to wheat, 

 rye, and more rarely barley, in Austria. The larvae, like that of the frit fly 

 with which it appears to have been confused, eats out the heart of the young 

 plant, causing it to wither. One larva may wander from one plant to another,
