 Berkeley, Cal, Bull. 297, August 1918, 72 pp., 28 figs. 



In this extensive bulletin on the cultivation of almond trees a chapter 

 is devoted to the more serious insect pests of this crop and their control. 

 The insects dealt with include the mites Bryohia pratcnsis and Tetra- 

 nychus telayius, Anarsia lineatella (peach twig borer), Aegeria opalescens 

 (California peach borer), thrips, grasshoppers, and Plodia intcr- 

 piinctella (Indian meal moth).

 Place for Econom.ic Purposes. — Science, Lancaster, Pa., li, no. 

 1330, 25th June 1920, pp. 640-641. 



Parasitic Nematodes of plants are held in check in many instances 

 b}^ a useful group of Nematodes known as mononchs, but as these 

 generally feed on the other Nematodes found in the soil around the 

 infested plant and not on those in the plant itself, the destructive 

 species are frec]uently imported into fresh areas without their enemies. 

 The value of mononchs as enemies of Nematodes and the advisability 

 of their introduction into infested areas is emphasised.

Part of the information in this paper dealing with Nematodes 

 associated with the beetles, Ips typograplms and Hylobius abietis, 

 has been previously noticed [R.A.E., A, ii, 375]. Other organisms 

 infesting Ips typographus are Gregarina typographi, sp. n., Telospori- 

 dinni typographi, sp. n., and a Hymenopterous parasite, Diplochis 

 oninivoms, Wlk. The last-named apparenth' infests the adult beetles.
