SCALE INSECTS AND THEIR ENEMIES IN CALIFORNIA. 



By John B. Smith, Xew Brunswick, X. J. 



[Author's abstract. 1 ] 



So much has been published on the subject of the beneficial effects 

 of predaceous insects introduced into California to destroy injurious 

 scales that the farmers of Xew Jersey felt as if a similar method should 

 be at least tried in Xew Jersey to rid them, if possible, of the San Jose 

 or pernicious scale. 



The matter was discussed in the Horticultural Society and in the 

 Xew Jersey State board of agriculture with the result that an appro- 

 priation was made by the legislature of the State for the purpose of 

 investigating the scale in California and for introducing into Xew 

 Jersey such of its enemies as might offer a fair chance of being bene- 

 ficial and of maintaining themselves in its climate. The investigation 

 was made in May and June, principally in the southern parts of Cali- 

 fornia, and covering the fruit-growing regions as far north as Marys- 

 ville, in the Sacramento Valley, Specifically, the points touched were 

 Los Angeles, Santa Barbara, Elwood, San Diego. National City, Kiver- 

 side, San Bernardino, Ontario, Pomona, Clermont, Pasadena, San 

 Francisco, Berkeley, San Jose, Mountain View, Palo Alto, Sacramento, 

 and Marysville. 



Throughout the State, or rather wherever examination was made, 

 the San Jose scale was still found to be present in more or less con- 

 siderable numbers; but south of San Francisco it was nowhere found 

 in troublesome quantities. Xorth of that point, except in the imme- 

 diate vicinity of San Francisco, the scale was still a dangerous and 

 troublesome insect and was kept in check only by persistent work on 

 the part of the growers, the favorite remedy being the lime, sulphur, 

 and salt wash. This seems to be entirely satisfactory as used in Cali- 

 fornia, and in the Marysville region, that is, in Yuba and Sutter coun- 

 ties, every grower sprays his orchard, no matter how large. Thousands 

 of fruit trees are sometimes massed together, and tons upon tons of the
