The condition of rye known as white-ear is due to various pests, 

 including Pediculopsis graminnm, Reut. During 1920 about 50 percent, 

 of the rye in the Voronezh district was attacked. The biology of this 

 mite is quoted, chiefly from the observations of E. Renter. As 

 it is an important pest in Russia, it is hoped that it will be given 

 further consideration by local entomologists.

During 1914 Lygaeonematus {Nematns) erichsoni, Hart., was very 

 abundant in the Penza district. The various stages of this sawfly 

 are described, as well as its life-history and the remedial measures for it 

 [R.A.E., A, ii, 372; iv, 243]. The author found the first adult on 

 9th May and the first eggs and larvae on 1st June. These eggs 

 hatched in seven days. There is one generation a year. The only 

 parasites found were a Tachinid, Argyrophylax bimacidata, Hart., 

 a Chalcid, Trichomalus sp., and the fungus, Isaria farinosa.
