GranS Rapids, in which he reports entirely similar conditions in the 
pea canning areas of the western part of the State. He feels that 
the hazzard to pea earners has almost passed and I have advised a 
policy of watchful waiting with everything ready to dust should 
developments warrant dusting. In other words, I think we are going 
to get by this year, but we came altogether too near the trouble to 
feel easy. 
Wisconsin J, E. Dudley (May 28): Aphids are attacking clover and alfalfa in 
Columbia and Jefferson Counties. They are probably less abundant 
than in the average year, and they are slowly but steadily increasing. 
There is no apparent damage as yet. On one 10-acre field a moderate 
infestation of the aphid has already been controlled 80 per cent by 
ladybeetles, which are very numerous. The season in this State is 
from 10 days to 2 weeks behind normal. 
New Mexico W. E. Emery (May 28): This aphid has just commenced to attack the 
garden peas in Dona Ana a County. 
CUCUMBERS 
STRIPED CUCUMBER BEETLE ( Diabrotica vittata Fab.) 
Connecticut J. A. Mante'r (June 22): The striped cucumber beetle is more abundant 
than usual at Mansfield on summer squash. Many plants would have 
been killed except for the control used. 
New York C. R. Crosby and assistants: The striped cucumber beetle appeared 
during the second week in June on Long Island in very serious numbers 
and was recorded as seriously abundant about the middle of the month 
in western New York. 
Virginia W. J. Schoene (June 20) : This pest is rather severe on squash and 
mBlons from the Piedmont and the Coastal Plain to tidewater. 
Indiana J.J. Davis (June 15): This pest has been the subject of numerous 
complaints the past month. 
Kentucky H. (Jarman (June 14): This insect is attacking cucumbers at Bowling 
Green, causing severe damage. 
Wisconsin Van W. Cass (June 10) : The striped cucumber beetle is very bad on 
cucumbers in the locality of Madison. 
J. E. Dudley, Jr. (June 11): The striped cucumber beetle is attack- 
ing melon, cucumber, and squash at Madison. It is less abundant 
than usual for this time of year, but the season is quite backward. 
Only one or two beetles were seen in May. Seedling cucumbers are 
entirely destroyed where no dusts have been applied. Two species 
of ground beetles are present. Calcium cyanid dust containing 15, 
25, and 50 per cent of calcium cyanid has been remarkably effective 
in killing beetles on cucurbits . Even beetles caught in flight die 
immediately. There appears to be no question that this dust will be 
completely effective against this insect.
