The Plum Curculio, ])y A. L. Quaintance and E. L. Jenne, U. S.

Oiu- Federal Bm-eau of Entomology is to be congi-atulated upon having issued 

 another comprehensive and well illustrated monograph upon an important pest. 

 The careful study of the biology of such an insect in various representative sections 

 of the country is invaluable because of the ligtt thrown on methods of control. 

 This type of work is peculiarly appropriate to a Federal agency. » 



This is both a full account and an important contribution to our knowledge of 

 the plum curculio. The original description is reproduced, followed by a detailed 

 history of the insect and a discussion of its distribution, food plants, life history, 

 etc., the work closing with an exhaustive bibliogi aphy. Reference to the map 

 shows that this common species is confined to the eastern and central United States 

 and to the eastern and central part of southern Canada. The annual loss is esti- 

 mated by the authors at $8,500,000. There are detailed records of oviposition, 

 showing that ^4 of all the eggs are laid within six weeks, the egg period lasting six 

 or seven days. The larvae emerge from the fruit mostly at the end of the third week 

 from oviposition, the insects remaining in the soil three to six weeks, most of them 

 only four or five. This is particularly valuable since it is based on extensive 

 studies in several localities. 



The discussion of remedial measures includes a historical account of earlier methods 

 followed by a consideration of the relative value of collecting, spraying and culti- 

 vation for the destruction of pupae. The authors hold that the older method of 

 jarring is giving way to the more modern .spraying with poisons, supplemented po.s- 

 sibly by cultivation for the destruction of pupae. Experiments show that the 

 latter results in the average destruction of about 33% of the insects. It is worthy 

 of note that the one spraying for the codling moth just after the blossoms fall is a 

 very effective treatment for the control of the curculio. The authors state that thor- 

 ough spraying greatly reduces the pest in all cases, though the degree of benefit
