FOODS ANIMAL PRODUCTION. 1003 



Report of the entomologist, C. M. Wkkd (Xew Hampshire SUt. liiil. 10, pp. S9-04, 

 fuj.s. 4). — Till' autlior states that the season of IWttJ was rcniarkal)le lor a cimtinuanco 

 of the attack of tho Araeiican teut catcii>illar and an invasion by the army worm, 

 the former of ^Yhil•h was noted in Bulletin 38 of the station (E. S. R., 8, p, G13) and 

 the lattorin Bulletin 39 (E. S. R., 8, p. GOO). Besides this, the cankerworm, the cod- 

 lino- moth, the apple maji^got, the white grnh, and the May beetle were somewhat 

 injurious. The author passes briefly over the life history of the last and recom- 

 mends that parent beetles be destroyed by a spray of Loudon purple or Paris green. 

 The cabbage root maggot (Aiithomijla brassica) is also noted as doing some damage. 

 Cutworms are also noted. 



Report of the entomologist, (i. IT. Perkixs (Vermont Sla. Rpi. ISD'i, pp. lJG-l.f.'>, 

 figs. 3.3), — An alnujst entirely ('Oiiipiled account of tin; apple magot {Trijpeta pomo- 

 nella), tent caterpillar, wireworui, grasshoj)per, army worm, bud moth, chinch bug, 

 and cutworms. 



Phylloxera, A. V. Hayne {California Sla. NjH. TIUchU. Worl; 1S87-9.1, pp. 37o-37S).^ 

 The author answers tho (Question " What book on the I'liylloxera shall I read, and 

 where shall I get it f" often asked of the station by farmers, by saying that there is 

 no complete work on the subject in English. The most complete part of the litera- 

 ture, he thinks, is that treating of resistant vines. Ho speaks briefly on the subject 

 of the original home of the insect and its introduction into California, and then con- 

 siders the subject of its California history, answering charges made against <'xperi- 

 nientation, and pointing out that the prediction (made wlien the subject was new) 

 that the insect would spread and not become localized has been verified. The rea- 

 son for the slow spread of the insect in California is attributed chiefly to the rarity 

 of the winged form. 



Destruction of the grapevine leaf beetle with pyrethrum, L. Deouiixy 

 {Prog. Agr. it Tit., 14 (1S97), Xo-s. 13, pp. 373-377; 14, pp. 407, -iC>5).— The author dis- 

 cusses several methods of destroying this beetle {Graptodera ampelophaga), siich as 

 mixing pyrethrum with copper spraying solutions at the rate of 1 to IV kg. ot the 

 former to 500 hectoliters of the latter, and mixtures of 1 part of pyrethrum and 4 

 parts by weight of sulphur. The most thorough method is to employ the first of 

 these and then to gather the leaves to destroy the larvsc that can not be reached by 

 the spray. A letter is quoted which states that good results were obtained by the use 

 of a mixture of lime and pyrethrum in the proportions of 2.75 kg. of the former to 

 0.25 kg. of the latter. The editor also states that a decoction of ciual parts of 

 Quassia amara and Delphinium staphysagria has been snccessfnlly employed. 



Destruction of the grapevine leaf beetle by means of a decoction of tobacco, 

 L. Degrully {Prog. Agr. et Fit., 14(1397), No. 16, p. 474).— A letter is quoted which 

 states that a solution of tobacco made of U liters of the juice of tobacco and 100 

 liters of water has been used with success. 



A new powder distributing apparatus, L. P. de l.\ Bathe (Prog. Ar/r. et Vit., 

 14 (1897), No. 8, pp. 220-ii23, figs. 5).— The apparatus is a cylinder i)rovidcd with a 

 bellows at the top, a lever for working the same, a flexible tube from the bottom 

 for directing the powder, and with straps for fastening to the back of tiie worker. 

 A device in the bottom of the cylinder and a tube from the bellows regulate tiie 

 "feeding" of the powder and prevent the distributing tube from becoming dogged.
