Report of the entomolog'ist, J. B. Smith {Ne)i: Jersey Slas. Rpt. luoi, ]>p. .}i;;i- 

 5S7, figs. 36). — This report contains, as usual, a general account of the insect dej^reda- 

 tions in New Jersey during the year. Notes are given on the prevalence and means 

 of combating fall webworm, white-spotted tussock moth, catalpa sphinx, tomato 

 hawk moth, swallow-tail butterflies, plant lice on currant, apple, strawberry, cherry, 

 maple, plum, hickory, and pea, and various scale insects. The author had good suc- 

 cess in the use of arsenate of lead in destroying fall weV>worm. Notes are given on 

 the damage caused by the destructive pea louse and on experiments with machines 

 specially devised for destroying this insect. Most of the experiments were made 

 with potash whale-oil soap, 1 lb. to 6 gal. of water. This remedy proved effective 

 and perfectly harmless to the {plants. Among various kinds of scale insects mention 

 is made of oyster-shell bark-louse, tulip soft scale, rose scale, and San Jose scale. The 

 extension of the latter insect is said to be slower at present than in former years. It 

 is not considered a menace to shade and forest trees. Crude petroleum is considered 

 the best remedy, while lime-sulphur-and-salt wash was used with excellent success. 

 Notes are also given on shade tree insects (including elm-leaf beetle, wood leopard 

 moth, bagworm, and an undetermined maple-leaf stalk liorer) ; orchard insects 

 (including rosebugs, silky June beetles, plum curculio, sinuate pear borer, pear 

 midge); and also on Hessian fly, angoumois grain moth, rhubarb beetles, asparagus 

 beetles, tortoise beetles, potato beetles, cranberry insects, mosquitoes, and Ligi/rus 

 relictus said to be injurious in a larval stage lipon the roots of pyrethrum. Experi- 

 ments were made with a number of insecticides, including arsenate of lead, whale- 

 oil soap, tobacco extract, Yankee Yellow, Pyrox, Hammond's Thrip Juice, Kretol, 

 and petroleum. Whale-oil soap did not prove a successful remedy as a winter treat- 

 ment of San Jose scale. The results obtained with this insecticide in summer were 

 very satisfactory. The author gives a detailed report of some operations with crude 

 petroleum as an insecticide. It is believed that this material is the best insecti- 

 cide for use against San Jose scale. The preferred period for application is just pre- 

 vious to the beginning of growth in the spring. 



Notes are given on 2 introduced beneficial insects, Tenodera sinensis and Mantis 

 religiosa. Eggs of these insects were introduced into New Jersey, but it is not known 

 at present whether the insects have been successfully established in the State. The 

 author refers briefly to the miscellaneous work of his department and to the insects 

 mentioned in the crop l)ulletins in New Jersey. An investigation was made of injury 

 to cranl)erries by the cranberry katydid, Scudderia texensis. A number of experi- 

 ments were made in testing the value of fungus diseases in destroying this insect. In 

 experiments made on cranberry bogs it was found that the eggs of this insect were 

 often laid in the leaves of Panicum dichotomum. It is not certain whether the eggs 

 can survive the winter underneath the cranberry bogs in such situations. Notes are 

 given on the habits and life history of the insect. It is concluded that no reliance 

 can be placed on fungus diseases of this insect, or on insecticides, or the cooperation 

 of turkeys and other fowls. It is recommended that the underbrush and rubbish on 

 the ground surrounding the bogs be Inirned annually. This can perhaps be best 

 accomi)lished ])y the use of the cyclone burner, such as was employed by the Gypsy 

 i\Ioth Connnission. 



The author presents a detailed account of the mosquitoes in New Jersey, including 

 a discussion of their prevalence and means of distribution, the species concerned, and 

 the results which have thus far been accomplished in the investigation of means for 

 exterminating them. Circular letters were sent to various parts of the State for the
