ENTOMOLOGY. 



The San Jos6 scale in New Jersey {New Jersey Stas. Bui. 106, 

 pp. 34, fi(js. 5). — This bulletin treats of the introductiou and spread of 

 A.spicUotus jJerniciosus iu New Jersey, its life history, description, ene- 

 mies, and treatment. The scale was introduced on Kelsey plum trees 

 from California in 1886 or 1887 by two nurseries, and spread rapidly, 

 attackiug- other fruits as well, especially pears. In 1889 or 1890 the 

 lirst scaly stock was distributed from these nurseries to different parts 

 of New Jersey and other States. In New Jersey the scale has not 

 been found on the red shale soil which occupies the northern half of 

 the State, although south of this it has been found in every county. 

 As California fruit, pears in particular, are frequently infested by the 

 scale, it is urged that great care be taken to avoid a fuf tber infection 

 with the pest.
