lO days; in less than a month's time the characteristic white fungus cushions

 results thus far obtained indicate that the pest may be greatly diminished by 

 the use of this fungus. 



On the history of the nonne disease, C. von Ttjbeuf ( Naturw. Ztschr. Forst- 

 u. Landw., 9 (1911), No. 8, pp. 357-377). — This is a review of investigations 

 made of the wilt disease of the nun moth. 



Report on the mosquito work for 1910, J. B. Smith (New Jersey Stas. Rpt. 

 \9W, pp. 377'-'i2-'i, pis. 3, fig. 1). — This is a somewhat detailed report of the 

 work of the year, and includes reports on local conditions and on Azolla in- 

 vestigations previously noted (E. S. R., 24, p. 562). Brief notes on the habits 

 of certain mosquitoes are appended. 



Fi-uit fly campaign, W. M. Giffard (Hmcaii. Forester and Agr., 9 (1912), 

 No. 8, pp. 23(j-i39). — A peculiar condition affecting a large percentage of mango 

 fruits during the present season, at first supposed to have been due to the 

 attack of the Me<literranean fruit fly, has been found to be caused by the mango 

 weevil. The attack of this weevil, which has been exceedingly prevalent 

 throughout Honolulu, is said to bring about fermentation and subsequent rotting 

 of the fruit.

The life history of Nosema apis, and the significance of the various 

 stages of the parasite in the disease, H. B. Fantham and Axnie Porter (Jour. 

 Bd. Agr. [London], 19 (1912), No. 2, Sup.,8, pp. 57-78, pis. 3).— The life cycle of 

 N. aj)is in the adult bee is summarized by the authors as follows : 



" When the spore is taken up mixed with food, it generally passes forwards 

 into the chyle stomach of the bee before much change occurs in it. Within the 

 chyle stomach the spore wall is softened by the action of the digestive juice of 

 the bee, which penetrates to the spore contents. Stimulated by the juice, the 

 sporoplasm apparently presses the vacuole, with the result that the polar fila- 

 ment is forcibly ejected. It serves for a short time as an organ of attachment, 

 fixing the spore to the gut wall. The sporoplasm concentrates and moves for- 

 wards, whereby the ix)lar filament is forced still farther outwards, and becomes 

 disconnected from the spore. The sporoplasm, retaining 2 of the nuclei, creeps 

 out from the sporocyst, leaving the 2 sporocyst nuclei behind. The free sporo- 

 plasm becomes amoeboid. The binucleate amcebula creeps about over the in-
