Borer in jowar, M. M. Desai (Poona Agr. Col. Mag., 6 (1914), No. 1, pp. J^l- 

 43). — The sugar borer Chilo simplex is reported to have injured the jowar or

A light trap for catching cutworm moths, G. P. "Weldon (Mo. Bui. Com. 

 Hort. Cat., 3 (1914), No. 7, pp. 284, 285, fig. i).— An illustration is given of a 

 trap used in sugar beet fields at Oxnard, Cal. This consists of a shallow gal- 

 vanized iron pan about 4 ft. in diameter set on a platform a few feet above 

 the ground, over which is hung a gas burner inclosed in a globe and connected 

 with a tank within the frame, in which acetylene gas is generated. 



It is stated that on the morning of May 18 from 1,200 to 1,500 moths were 

 found to have been trapped during the night. A trap placed on a beet dump 

 with an electric light to attract the moths is said to have caught as high as 

 7,000 moths during a single night. Most of the moths are said to represent 

 the cutworm species Peridroma saucia.

A new schizogregarine (Caulleryella aphiochaetse n. g. and n. sp.), an 

 intestinal parasite of the larva of a cyclorrhaphous dipteran (Aphiochaeta 

 rufipes), D. Keilin (Compt. Rend. Soc. Biol. [Paris], 76 (1914), No. 16, pp.

Leprosy: Flies in relation to the transmission of the disease, J. A. Honeij 

 and R. R. Parker (Jour. Med. Research, 30 (1914), ^^o. 2, pp. 127-130) .—This is 

 a preliminai'y report of studies conducted at the Penikese Hospital Laboratory. 



Of 95 flies used in the work, 59 were Musca domestica, 3 Muscina stahiilans, 

 30 Stomoxys ealcitrans, 2 Lucilia sp., and one an undetermined sciomyzid. 

 The study shows that a fly will feed continuously for from 3 to 31 minutes; 

 that the digestive tract was completely emptied in from 52 to 72 hours; that 

 the average number of excreta deposits was for the M. domestica male during 

 46 hours 25+ and for the female 35+ (during the first 24 hours the greatest 

 number of ejections occurred and after the first 8 hours), and for the S. calcir 

 trans male during 61 hours 40+ and for the female 86+ (during the first 

 24 hours the greatest number of ejections occurred and after the first 3 hours) ; 

 and that the average time after feeding before the first ejection varies con- 

 siderably between 5 and 45 minutes, but the average is about 13 minutes. 

 " It was found that of 12 flies of different species caught in the rooms of 

 patients only 2 (M. domestica) showed the acid-fast bacilli in the excreta 

 deposits, and that of 6 flies (also M. domestica) allowed to feed on the 

 lesions of patients the excreta gave negative results. . . . From the 41 flies 

 fed on the contents of pustules the best results were obtained. Of 21 flies 

 (M. domestica) 15 were negative and 6 positive. Of 8. calcitra/ns 20 were 

 used which gave 4 negative and 16 positive results. Of another series of 

 six flies (three of each species), two gave positive findings, two questionable 

 acid-fast bacilli, and two were negative. ... In no other species of flies 

 other than M. domestica and S. ealcitrans were the acid-fast bacilli found in the 

 excreta."
