This second part of a popular manual [R.A.E., A, ix, 476] deals 

 with the fungous and insect enemies that occur from April to October 

 in Holland.

The red scale of citrus, Chrysomphalus dictyospermi, Morg., has 

 appeared in the province of Salerno, where it has four generations

This is the first part of a list which is intended to comprise all the 

 Russian literature published during 1917-1921 on applied entomology 

 and which also includes publications on applied zoology. It is hoped 

 that a second part will complete the list.

It is almost impossible to obtain peas entirely free from the ravages 

 of Bruchus pisorum {pisi) from fields that have been infested with 

 this beetle, even when systematic remedial measures are employed. 



A method has, however, been devised by which the clean peas may 

 be separated from the infested ones. After harvesting, they should 

 be immersed in a concentrated salt solution, the specific gravity of 

 which must be higher than that of the least seriously damaged peas, 

 so that the latter will all rise to the surface. For the larger varieties 

 of peas it is advisable to use Chile saltpetre, as a higher specific gravity 

 may be thus obtained. The hquid may be utilised afterwards as manure. 

 Care must be taken to wash and dry the peas thoroughly after they have 

 been removed from the salt.
