[Polychrosis viteana], there being some ground for belief that a single 

 timely and thorough spraying will be sufficient and thus do away 

 with the objectionable spray residue on the fruit at harvest time. 

 Special attention has been given to the use of insecticides in pecan 

 orchards in Georgia and Florida. Experimental tests were made of 

 miscellaneous proprietary insecticides and others, both alone and in 

 combination with fungicides. In view of the present high cost of lead 

 arsenate the value of calcium arsenate has been tested, the results 

 indicating that it may be used in all situations where Paris green has 

 been employed, and that it will be a satisfactory substitute for lead 

 arsenate when used with lime or fungicides containing lime. 

 Investigation of an Oriental insecticide, derris, has shown that it acts 

 both as a stomach poison, when however it is sffective against only a 

 few insects, and also as a contact insecticide being efficient against 

 a wide range of pests. Tests on the ovicidal action of nicotine have 

 shown that it is not sufficient to control Cydia pomonella satisfactorily 

 when used alone. The work on cranberry insects in New Jersey has 

 been completed, and a bulletin on the subject has been pu Wished 

 [see this Revieiv, Ser. A, vi, p. 561]. Several of the important eastern 

 cranberry pests having been introduced into Washington with plants 

 from the east, it will be necessary to study them under their new 

 western conditions. The methods of control of the blackhead fireworm 

 [Rhopobota vacciniana] adopted in the east are also effective in the 

 State of Washington. It appears probable that the peach borer 

 [Aegeria exitiosa] may be controlled by the proper use of para- 

 dichlorobenzine applied in small doses round the base of the tree in 

 autumn, and this at a minimum cost. The so-called oriental peach 

 moth [Cydia molesta], a newly- established peach pest from Japan, 

 also attacks apples, pears, quinces, plums and cherries, and bids fair 

 to be a serious pest. About 50 species of parasites of the grape-berry 

 moth [Polychrosis viteana] have been found, only 7 or 8, however, 

 being of sufficient numerical importance to be at all efiective. A new 

 disease attacking the citrus mealy-bug [Pseudococcus citri] has been 

 discovered. Eradication work in connection with a Japanese beetle 

 {Popillia japonica) has been systematically undertaken. This pest 

 was probably introduced in 1911 in the egg or larval stage in the soil 

 surrounding the rhizomes of Japanese iris. It is now heavily infesting 

 about 625 acres, -vvith scattered infestations over some 7,000 to 10,000 

 acres and with outlying infestations over not less than 25,000 acres. 

 It is a very general feeder, attacking grape, apple, cherry, buckwheat, 

 sweet potato and maize, as well as many ornamental plants and weeds. 

 The immature stages are passed in the soil, where the larvae feed on 

 decaying vegetable matter. The adults appear in midsummer, 

 continuing tiU cool weather in autumn ; spreading occurs during the 

 hot weather, at which time the beetles are strong fliers. Eradication 

 has been attempted by treating infested soil with sodium cyanide 

 solution, by ploughing the breeding grounds, and by keeping the 

 insects away from roadsides by the use of kerosene and other means. 

 Direct measures include the application of poisons to the entire infested 

 areas as nearly as possible, working from the periphery inwards, and 

 by hand-picking the adults. 



Cereal and forage insect investigations under the control of 

 Mr. W. R. Walton made it evident that Pyrausta nubilalis (European
