INSECTS AFFECTING GREENHOUSE 
AND ORNAMENTAL PLANTS 
OYSTER-SHELL SCALE ( Lepidosaphes ulmi L.) 
New York. R. E. Horsey (April 23): Last year's branchlets of European ash, 
Fraxinus excel sa and Hoary Willow, Salix Candida infested by scale were 
dead, caused "by the cold winter or the scale or by both. Eggs under ful! 
sized scales were shriveled and dead. Evidently the death of the infest* 
branch has an effect on the eggs. The branches and eggs of the scale we: 
both alive on Albert honeysuckle, Lonicera albertii and a lilac from the 
Orient, Syringa sp. The lilac was badly incrusted with scale. 
Illinois. W. P. Flint (April 20): Examinations of the oyster-shell scale i] 
the east-central part of the State show that most of the overwintering 
eggs have been destroyed by mites or the scale killed by parasites 
CHAFF SCALE ( Parlatoria pergandei Comst.) 
Mississippi. C. Lyle (April 23): Infested leaves of Camellia .japonic a 
were received from a grower at Hazlehurst, Copiah County, on April 16; 
jasmine in a garden at Starkville, Oktibbeha County, was observed being 
injured on April 18. 
A SCALE INSECT ( Odonaspis penicillata Green) 
Mississippi. C. Lyle (April 23): Bamboo twigs showing very heavy infesta- 
tions were received from a correspondent at Gulfport, Harrison County, or 
March 23. He indicated that many of the bamboo plants in that vicinity 
were dying out and he believes the scale to be partially responsible. 
EtIONYMUS 
EUONYMUS SCALE ( Chionaspis euonymi Comst.) 
Virginia. H. G. Walker and L. D. Anderson (April 26): As usual, the euonyrm; 
scale is rather abundant on many plantings of Euonymus at Norfolk. 
Mississippi. C. Lyle (April 23): Heavy infestations on Euonymus were report 
from Jackson, Hinds County, on April 12, and from Hattiesburg, Forrest 
County, on April 17. 
GENISTA <; 
A MOTH ( Tholeria reversalis Guen . ) 
California. R. E. Campbell (April 24): So far this insect is not so abundar 
at Alhambra as it has been during the past 3 years, when most of the 
genista bushes were defoliated to a large extent.
