PEACH-TWIG BORER ( Anarsia lineatella Zell.) 
J. A. Hyslop (July 15): The peach-twig borer has infested from 
80 to 100 per cent of the twigs in eastern Montgomery County. 
Calif ornia Weekly News Letter, Vol. 5, No. 13 (June 30): A notice- 
able decrease in the prevalence of the peach-twig borer is noted in 
orchards in the Burbank and Lankershim districts of Los Angeles 
County, as a result of spray applications made last fall for this 
pest. Orchards which were badly infested last season show from 
60 to 70 per cent decrease in infestation as compared with the 
previous year. 
GREEN PE^CH APHID ( Kyzus persicae Sulz.) 
G. E. Smith (July 15): This aphid is found more generally than 
usual in Orleans County. 
BLACK PEACH APHID ( Anuraphis persicae - niger Smith) 
Roy E. Campbell (July 12): The black peach aphid is reported by 
horticultural inspectors to be particularly numerous this season 
in the San Fernando Valley. Growers are spraying with nicotine

SHOT-HOLE BORER ( Scolvtus rugulosus Ratz .) 
G. E. Smith (July 15): This borer is destructive in Orleans County 
to trees injured by the peach-tree borer. 
5. W. Frost and E. M. Craighead (July): The fruit-tree bark- 
beetle, Scolvtus rugulosus Ratz., is doing considerable damage to 
young cherry shoots in certain orchards in Adams County. The work 
of these oeetles resembles the work of the oriental peach moth, 
but the cavitifs are much smaller. The injury thus far has been 
noted only on sweet cherry. This type of injury has previously 
been noted in literature but is not commonly found. 
W. E. Hinds (June 30): Winter injury to pecans and young fruit 
trees was severe and is being followed by bark-beetles. These 
include the fruit-tree bark-beetles in peaches and a species in 
pecans .
