[Notes on insect pests] {■lour. lid. Agr. [lj()ii(hni\. 1(1 (190!)), No. 3, pp. 

 210-212). — Reports on the occurrence of the pear-leaf blister-mite ( BriopJn/cs 

 pyri) indicate that the pest is increasing in frequence in Great Britain. A 

 serious attacli of the willow beetle ((lalcrucclla lincohi) in Somerset ruined 

 many willows for commercial purposes, in some cases the whole crop being 

 destroyed. 



[Notes on insect pests] (Jour. lid. Atjr. [Loiidtui], Id (l'.)UU), No. .'/, pp. 

 .^93-297, pis. 2, fig. J). — The bulb mite (Rhizoglyphus cchinopus) was reported 

 as a source of injury by a number of correspondents, particularly the larger 

 growers in Ireland. Vaporite and Apterite lightly i)owdered over a scale 

 of the bulb were found to kill the moths in a short time. The narcissus fly 

 (Mcrodon equcstris) was a great pest of narcissus bulbs 4 or 5 years ago, but 

 is now rarely found due to the practice of destroying all sickly and infested bulbs. 



Leaves of the evergreen oak infested by the larvte of LithocoUctU mcsmniella 

 wei'e rec-eived from (lUildford with the statement that apparently every ever- 

 green oak in the immediate neighborhood was affected and that some of the 

 younger trees had injuries on every leaf. The Cai-eless variety of the goose- 

 berry is believed to escape generally if not always the attack of the red spider. 

 The occurrence of the asparagus beetle, pear midge, Otiorhynchus picipes, 

 liyturus tomentosus, Dilophus fcbrilis, Spathcgastcr haccarum, and Terus ter- 

 iniiKilis are also noted. 



Insects of the year 1907 [in Scotland], R. S. Macdougall (Trans. High- 

 land and Agr. .s'oc Scot., .7. scr., 20 ( l!>0!i), pp. 305-308). — The beech-felted scale 

 (Cryptococcus fagi) is said to be widespread over the country and destructive 

 to the beech. The gooseberry and currant saw-fly (Nematus ribesii) and the 

 magpie moth (Abraxas grossulariata) continue every year to be most trouble- 

 some. Methods of combating these pests and the oyster-shell scale, woolly aphis, 

 sprnce-gall aphis, larch aphis, and ox warble flies are considered. 



Injuries to cultivated plants by insects (Ber. K. Lchranst. ^¥ciH, Obst u. 

 (lartcnbau (Iciscnhcini, 1901, pp. 275-305, figs. 8). — This report consists of a 

 number of short articles on the insects that were injurious in Germany during 

 T.)U7. 



Among the insects considered by G. Liistner are several scale pests of poma- 

 ceous fruits, the injuries by and parasites of Cochylis ainbiguclla, the in- 

 juries by bagworms, Eudemis botrana and Julus londinensis, observations on 

 the occurrence of mites on fruit trees and the grapevine, and injury to apples 

 by Argyrcsthia conjugcUa. Accounts are given by E. Molz on the cause of color 

 dimorphism in Rhynrhitcs betulcti, on the terminal galls of the branches of 

 Abies nobilis caused by Chcnnes picece, and of the injury to Ampelopsis 

 quinquefolia by Hpilosoma lupricipeda. H. Morstatt reports investigations made 

 of Diaspis falla.r and of a new pest of the strawberry in Germany. 



Some new galls and gall formers from Chile, Kieffer and P. Herbst 

 (Ccntbl. Balct. [etc.], 2. Abt., 23 (1909), No. 1-5, pp. 119-126, figs. ?).— Galls 

 formed by trypetids, cecidomyids, aphids, coccids, etc., on several species of 

 l>lants including Hydrangea are here considered. Several genera and species of 

 gall formers are described as new. 



The influence of different kinds of fallow on some injurious insects, N. 

 KvRDUMov ( Yuzh. Ross. ,SV7.s7.-. KIto.t. (Iliaz.. 1907, No. 35; abs. in Zliur. Opuitn. 

 Agron. \Russ. Jour. Erpt. Landw.]. 10 (1909), No. 2, pp. 199, ;^00).— The author 

 shows that early fallow contributes to the destruction of Anixoplia austriaca 

 and that black fallow is similarly destructive for Agrotis svgctum.
