Russian Congress of Workers in Applied Entomology, Kiev, 



1914, 10 pp. 



This is a paper read at the first All-Russian Congress of Economic 



Entomologists, held in Kiev, September 1913, in which the author 



shortly describes the organisation of local Entomological Institutions in 



North America. He attributes the splendid activity displayed by these 



institutions in the United States and Canada, not only to the personal 



talents of the heads of the various departments, but also to the proper 



recognition of the requirements and necessities of the countries by 



the authorities.

A general account of the life-history of the Aphididae, together with 

 hints on their collection and preservation. Reference is made to the 

 fact that certain species periodically change their food-plants. 

 A. avenae, for example, begins the year on apple trees, migrates after 

 two months to wheat or grasses, and returns to the apple in the autumn ; 

 Phorodon humidi migrates from damsons to hops in Kent ; A. rumicis 

 migrates from docks and thistles to beans ; and many species of the 

 genus Chermes alternate between a Picea and some other coniferous 

 tree of a different genus. 



Microscopical examination is necessary for accurate determination 

 of species, and for this work freshly killed specimens may generally 

 be transferred to clove oil, left there until cleared and then mounted 

 in Canada balsam. Specimens which have been kept for some time 

 in alcohol, should, after dehydration, be transferred to clove oil and 

 mounted in canada balsam. A few species, such as those of the genus 

 Chermes, require different treatment, generally fairly good results being 

 obtained by soaking the specimens in a rather dilute solution of acetic 

 acid or caustic potash and then transferring to clove oil.
