A brief portion of this bulletin is devoted to the prevention and 

 eradication of insect pests. These are tabulated according to the crop 

 attacked, with particulars of damage caused and remedial measures 

 advocated, only the popular names of the insects being given.

The larval characters of the Ruteline group of Scarabaeid beetles 

 a.re quoted from Schiodte, and the undetermined larva under considera- 

 tion is stated to be probably that of Strigoderma arboricola, F. A key 

 is given for distinguishing North American and European larvae that 

 are closely related to or likely to be mistaken for that of Popillia 

 japonica.

 Washington, D.C., xxiii, no. 3, March 1921, pp. 62-63. 



The M3m'iarid, Anaphoidea conotracheli, is recorded as parasitising the 

 eggs of Rhagoletis pomonella, Walsh, in Connecticut. It has also been 

 reared from Coeliodes {Craponins) inaeqnalis, .Say (grape curculio). 

 The life-cycle in the apple maggot is probably similar to that in the 

 weevil, i.e., 10 to 11 days from egg to adult. The parasitism ranged 

 from 25 to 30 per cent., indicating the possible importance of this 

 parasite in the natural control of A', ponwjiclla.

Experiments with poison baits for cutworms and army worms have 

 shown that the effectiveness of the various formulae depends largely 

 upon the species against which they are used. 



Tests in the protection of stored food from insects showed that 

 a temperature of 43° F. prevented the development of Tribolium 

 confusum, Duv. (confused flour beetle), which is one of the worst pests. 

 A study of the susceptibility of cereals to insect attack led to the 

 conclusions that the insects that attack sound grain cannot survive 

 in milled products, while those that work in milled products cannot 

 survive in sound grain. Grain that has already been attacked by
