THE MOBS IMPORTANT RECORDS FOR APRIL, 1933 
Luring late March and early April cutworms were very troublesome to toma- 
toes and Irish potatoes in southern Mississippi. 'The outbreak of the western 
array cutworm reported in the last number of the Insect Pest Survey Bulletin 
from Kansas terminated about the third week in April, and during the last week 
in the month moths were emerging in numbers. In one instance during the height 
of the outbreak populations as high as 90 cutworms per square foot were ob- 
served near Manhattan. This species was also troublesome in several localities 
in Montana. 
Grasshopper eggs examined late in April in North Dakota and 7/yoming were 
found to have wintered with very low mortality; 90 per cent survival is re- 
ported from North Dakota and 95 per cent from Wyoming. 
An outbreak of the mormon cricket has developed in eastern Idaho. 
The wireworm Heteroderes laurentii Guer. was very troublesome in southern 
Alabama early in the month, and in many patches every kernel of corn was at- 
tacked. 
The vegetable weevil has been found at Clemson College, S.Ci - This is the 
northeasternmost record for this insect and the first record for this State. 
Heavy rains during the second and third weeks in April had very little ef- 
fect on hibernating chinch bugs in Illinois. The insect also seems to have 
passed the winter successfully in Missouri, Kansas, and parts of Iowa. 
In general apple aphid s are decidedly less numerous than usual. The rosy 
apple aphid, however, during the later part of the month developed in trouble- 
some numbers in New York and Virginia. 
The first specimen of the plum curculio was recorded from hibernation in 
eastern Jackson County, Miss., on March 20, at Harriman, Tenn. , on April 6, 
and at Newark, Del., on April 10. These insects suffered such heavy mortality 
in the Fort Valley peach district of Georgia that little trouble is anticipated 
from this pest this year. 
Following a very dry March, strawberries in the Cliadbourn district of North 
Carolina were very heavily infested with the common red spider. In some locali- 
ties this infestation was so heavy that no marketable crop was harvested. 
A single egg mass of the gipsy moth has been discovred at Mount Freedom, 
Morris County, IT. J. This is the first record in this State since the eradica- 
tion campaign was closed four years ago. 
Heavy infestations of the southern pine beetle' have been found in southern 
Pennsylvania, western Maryland, and northern Virginia. This is the most notable 
outbreak since that of 1893 and is located in the northernmost part of the range 
of this insect.
