An elaborate review is presented of the appearance, distribution, and life historj of 

 this cutworm. The author discusses the number of generations, the egg, larva, and 

 other stages of the pest. Attention is given also to its insect parasites belonging to 

 various orders, with reference also to fungus and bacterial diseases. In the discussion 

 of methods for controlling the pesl the Bubject is discussed under different heads, 

 according to the stage of the insecl concerned. 



The larva of Plodia interpunctella, B. Wahli Zlschr. Landw. Versuchsw. Oesterr., 

 8 I 1905), No. 10, pp. 950 954). This pesl was found in fig coffee and also in a num- 

 ber of other food products. The systematic position of tin- moth i- briefly outlined, 

 and detailed notes are given on the external anatomy of the caterpillar, with par- 

 ticular reference to the number ami location of the bristles. 



Parthenogenesis in Otiorrhynchus turca, A. A. SsiLANTJEW (Zool. Am., ."' 

 (1905), No. 18, />/'■ fig*- -'•• — I" Btudying this insecl which has recently 



caused great damage to grapes in the region of the Black Sea, the author observed 

 that no males were to be found. Observations along this line Bhowed thai females 

 taken immediately after emergence and kept confined in glass jars during their w hole 

 life laid eggs which were perfectly fertile and developed into normal individuals. 



On the Cecidomyid forming the galls or pseudocones on Pinus longifolia, 

 E. P. Stebbing ( Indian Forester, 81 \ 1905), No. 8, pp. f£9-434, i' 1 - 1 1.- For some time 

 ira 1 1 s have been noticed on this pine tree which so closely resembled the cones as to 

 be mistaken for them. When examined by the author they were found to be due 

 to a species of Cecidomyia, which is briefly described. Notes are also given on a para- 

 sitic insect found upon the gall insect. 



A new enemy of the Douglas fir, R. S. Ma< d \ii. (Jour. />'</. Agr. [London], 



l .' i 1906), No. 10, />/>. 615-621, figs. /'). — Megastigmus spermolrophus was found infest- 

 ing the seeds of Douglas fir. 



This insect is described in its various stages. The eggs are laid in the young cones 

 of the Douglas fir and each seed is infested by one larva. In preventing the destruc- 

 tion of cones by this pest it is recommended that after the seed is collected it should 

 he subjected to treatment of bisulphid of carbon at the rate of 1 oz. for every 50 cu. ft. 



of air space. 



Notes on termites with special reference to the destruction of timber by 

 Calotermes brouni, T. Broun I New Zeal. Dept. Agr. Ann. Rpt., IS ( 1905), pp. ',■'■<>- 

 436, pis. 2). — It has been found that for railroad ties various woods may safely be 

 used which would otherwise soon he destroyed by white ants. This is due to the 

 fact that the ants are frightened away by the jar produced by passing trains. 



Calotermes brouni is an exceedingly injurious species, and notes are given on its in- 

 jury to various kinds of wood, especially Puriri and Kauri w Is. The insect is de- 

 scribed in its various stages. 



Spraying apples. Relative merits of liquid and dust applications, C. B. 

 Crandall (Illinois Sta. Bui. 106, pp. .'()■',- r,! , figs. 14).— -While a combination of 

 Bordeaux mixture and arsenicals has long been known to give satisfactory results in 

 the control of seal) and some of the other common fungus diseases of apples, as well 

 as codling moth and leaf-eating caterpillars, the method is somewhat extensive and 

 various experiments have been made to test the economy of dust sprays. 



The author's work along this line has been carried on for a period of 3 years, dur- 

 ing which various plats of apple trees were sprayed or dusted f rom 3 to 8 times daring 

 the season, the first application being made just as the buds were opening. Particu- 

 lar attention was given during this series of experiment- to the effect of treatment on 



apple scab, fruit blotch, codling moth, and curculio. It appears from these experi- 

 ments thai the pests just mentioned must be recognized as of a permanent nature and
