the State as a whole that apple plant lice are considerably 
reduced in numbers over last season, except for a few cases in 
individual orchards where for some reason or other there happens 
to be a considerable abundance. There is every indication that 
orchard plant lice will not be a serious factor this coming 
season. 
Virginia W. S. Hough (April l6): None of the three species of aphids, 
A nur aphis roseus Baker, Rhopalcsiphum orunifoliae Fitch, and 
Aphi s porni DeG-. , which usually appear on apple trees have appeared 
this season. Only two rosy apple aphids have been found to 
date and but two nymphs of Rhopalosiphum Prunifoliae Fitcfc. have 
been observed on the apple buds. Between $12,000 and $15,000 
worth of nicotine sulphate is usually used in the delayed dormant 
spray in orchards near Winchester, but this year the delayed 
dormant spray was applied without nicotine. 
West Virginia W. E. Rumsey (April IS): Aphis eggs, all species, are very 
scarce about Morgantown and also about Charleston, Kanawha County. 
In the eastern panhandle none of the Station men have been able 
to find any aphid eggs on the apple trees in Berkeley and Jefferson 
Counties. 
Indiana 
Illinois 
Maryland 
Bennet A. Porter (April 27): All species of apple aphids are 
almost totally absent from the orchards at Vincennes. Ho aphids 
have been seen except a half dozen individuals, which were probably 
the green apple aphid. 
W. P. Flint (April 20): Examination of apple trees in the cluster- 
bud stage in southern Illinois orchards have failed to reveal 
a single aphid of any species present. The same is true of central 
Illinois, where the trees are just showing green tips. It seems 
certain that aphids will be very scarce in Illinois apple orchards 
this season. 
APPIE APHID (Aphis pomi D eG. ) 
Ernest E„ Cory (April 2): The green apple aphid hatched at College 
Park on March 27. 
ROSY APPLE APHID ( Anur aphis roseus Baker) 
Maryland Ernest 35. Cory (April 2): The rosy apple aphid is extremely 
scarce at College Park. 
North Carolina Z. P. Met calf (March) : The eggs of what appears to be this species 
are much snore abundant in the mountains of the State than during 
the average season. 
Oregon 
Don C. Mote (March 19): Stem mothers wdth small colonies were 
first observed on this day on the developing cluster buds. All 
eggs observed had hatched.
