Two of the chief cabbage pests are Chortophila brassicae, Bch., and 

 Baris chloris, F. A general account of the life-history of, and measures 

 against both these pests is given. B. chloris oviposits on the stalks of 

 cabbage, on which the larvae live and pupate ; pupation also takes 

 place in the earth, in which the adult beetles pass the winter. 

 Affected plants should be destroyed and, in transplanting, young 

 cabbages should be grown as far as possible from infested areas.

The author urges the importance of the establishment, by the 

 Zemstvos and the Department of Agriculture, of Entomological Sta- 

 tions or Entomological branches of the existing Experimental Stations. 

 These stations should report annually, on the dates of appearance of 

 various insect pests and the amount of damage done ; on the influence 

 of local meteorological conditions and methods of cultivation on insect 

 life ; on the part played by parasites ; on experiments on the bio- 

 nomics of pests and their control conducted at the Station during the 

 year ; and on any special problems studied.

This is a continuation of the discussion on the economic importance 

 of weevils of the genus Apion, and the author here rephes to the 

 criticism of his views by A. Sopotzko [see this Review, Series A, iv, 

 p. 167]. He maintains his previous opinion, that these weevils have 

 no effect of economic importance on the crop of seed in clover. He also 

 denies the statement as to the injury caused by the burrow gnawed by 

 the laiv^ae in the base of the inflorescence for the purpose oi pupation, 

 which he insists is practically harmless.

 with Peas infested with Bruchus 'pisorum, L., is injurious.] —

 1916, pp. 654-655. 



Bruchus pisorum (pisi), besides damaging peas, is also certainly 

 injurious both to man and some animals, when present in peas used 

 for food. This is probably due to the presence of cantharidine in 

 the excreta and the bodies of the insects, though some insectivorous 

 animals including poultry are not affected by this poison. Infested 

 peas should therefore be cleaned by special machinery before being 

 used for food.
