TOMATO PIN WORM 
The tomato pin worm ( Gnor imp schema lycopersicella Eusck) appeared again 
in troublesome numbers in northeastern Pennsylvania, where it not only in- 
fested greenhouse tomatoes "but heavily infested numerous outdoor plantings 
near greenhouses. It was collected on tomatoes in a greenhouse in Norfolk, 
Va., in April. This is the first record of the insect in that State. In 
Florida, where it was first reported during 1932, it reappeared late in the 
season of 1933 but not nearly as seriously as the previous year. 
HARLEQUIN BUG 
The harlequin bug ( Murgantia histrionica Hahn) evidently suffered heavy 
winter mortality along the Atlantic seaboard, as populations were generally 
light throughout that region. Very early in the season it was unusually 
abundant in the East Central States, particularly from southern Ohio and 
southern Indiana to central and eastern Tennessee. Later, however, it 
appeared to decrease in numbers and was not so serious as was originally 
anticipated. 
FALSE CHINCH BUG 
During June the false chinch bug ( Nysius ericae Schill.) was reported 
from the West Central States through the Rocky Mountain region to the 
Pacific Coast, reports having been received from Minnesota, Iowa, Nebraska, 
Kansas, Colorado, Utah, Nevada, and California. Its principal damage was 
to cruciferous vegetables, though it was also reported as attacking straw- 
berry, potato, tomato, and flax. It was also reported as damaging orchards 
and vineyards. In California the outbreak extended from the upper 
Sacramento Valley to San Diego. This insect occurred in such enormous 
numbers at Wells, Nev., that it invaded the theatres, which had to be closed 
until the migration ended. 
PEA APHID 
During May heavy infestations of alfalfa by the pea aphid ( Illinoia 
pisi Kalt.) were recorded in New Jersey, Maryland, Kentucky, Missouri, and 
Kansas. In Maryland the outbreak was reduced to negligible proportions by 
a fungous disease. In Mississippi the insect was reported as attacking 
Austrian winter peas and English peas. In June it appeared in the cannery 
peas in Michigan. 
POTATO LEAFHOPPER 
Late in June the potato leafhopper ( Empoasca fabae Harr. ) became very 
abundant in the Norfolk trucking section of Virginia. Reports of similar 
abundance were received from Ohio and Iowa. During July the insect and its 
associated hopperburn were reported as abundant and destructive from southern 
New England^ through the Middle Atlantic States westward to Illinois and 
Minnesota. In the western part of that area dry weather, associated with 
the hopperburn, produced severe losses.
