-77- 
instar. Aoole grain aohid eggs hatched along with the green aohid, 
with many in the third instar when the early apole "buds opened. The 
general condition uo to Aoril 19 was, for rosv aphids, generally 
soot ted; for green and grain aohids, olentiful "but not as man^ as in 
most years. The exact situation as regards the extent of rosy aphid 
infestation could be determined by Aori] 19. 
H. N. Worthley (Aoril 22): At State College, aoole aohids were 
moderately abundant on aoole. On Aoril 15, obse?.-vptions showed 6.6 
aohids oer bud (200 buds); on Aoril IE, U.2 aohids oer bud, (200 buds). 
Temperature went to 19° F. on Aoril lo and the cold weather killed 
36 percent of the aohids. The aoole buds are now nearly in the ore- 
pink stage and of the aohids present, 93 percent are green aphids 
and 7 oercent grain aohids. Mo ros" aohids have been seen to date. 
Delaware. L. A. Steams (Aoril): Eggs of the grain aohid have hatched 
and were generally abundant on aoole on April 2. 
Virginia. W. J. Schoene (April 2-): Eggs of apple aohids hatched at 
Winchester as follows: Grain aphid on March 17 , apole aohid on 
March 20, vos^ aohid on March 23. Ho injury has been reoorted except 
in small unsprayed orchards. 
Ohio. W. H. Parks (Aoril 2U): Stem mothers of the aoole grain aphid are 
now giving birth to second-generation young at Columbus. The freeze 
of Aoril l6 apparently killed very few aphids, although the temperature- 
descended to 22 F. Aoole trees are ao'^roaching the full-pink stage. 
Missouri. L. Ha.seman (Aoril 23); In the early oart of the montn some 
aoole grain aohids were observed on buds in central Missouri, but by 
the last of the month only a few had aooeared. 
Mississiooi. C. Lyle and assistants (Aoril 23): The aople aphid was re- 
ported as moderately abundant in the vicinit ,r of Wiggins. Some colo- 
nies were being heavilv parasitized. 
Oregon. D. C. Mote (April 13): Rosy aohids were reoorted b^ B. G. Thomoson 
on aoole at Monroe. 
SA1T JOSE SCALE ( Asoidiotus pemiciosus Comst.) 
Delaware. L. A. Stearns (Aoril 3): Some infestation of 2-vear-old aoole 
trees in Bridgeville; three trees deed. 
Georgia. 0. I. Snapp (Aoril 3): Larvae of the twice-stabbed ladybeetle 
( Chilocorus bivulneras Huls.) oreying on the scale, are unusually abun- 
dant at Fort Valley. J. ?.. Thomson reoorts as many as 60 larvae on a 
scale-infested peach twig 12 inches long and 1 inch in diameter, the 
largest population of this predacious insect he ha.s ever observed in 
a single oeach tree.
