OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STaTES EOR APRIL, 1924 
During the past month the Hessian fly situation remained about as 
during March throughout the '.Vest-Central and Upper Mississippi Valley States. 
Following the abnormally wet fall of 1923 a very serious and unusual Hessian 
fly development has taken place in northwestern Kansas, extending far nest 
of the region where the Hessian fly is usually known as a pest. 
Throughout that part of the region covered by the chinch bug 
extending from Illinois to Kansas, this insect seems to have passed the winter 
under unusually favorable conditions. The bugs were observed on the wing on 
April l6 in central Illinois, between the 10th and 15th in central Missouri, 
and by the 15th and 21st in southern Nebraska. Emergence in Kansas was observed 
as early as April 7* 
Avery serious greenbug outbreak was reported from southern Oklahoma 
during the third week of April. 
Moths of the fall cankerworm are appearing in large numbers in central 
and southern New York State and Ohio. . 
The tent caterpillar is very generally prevalent and apparently much- 
more numerous than Usual throughout the New England and Middle Atlantic States 
southward to Delaware. 
The pear psylla began egg laying in southern New York on April 6 and 
heavy egg laying vzas reported in the northern tier of counties during the third 
week in the month. 
The application of 500,000 pounds of paradichlorobensene in the 
Georgia Peach Belt last fall appears to have been highly successful in con- 
trolling the' peach borer. The plum curculio in this same region passed the 
winter in unusually good condition and will probably be more serious than usual 
this year. 
A very interesting outbreak of the cowpea curculio, as a pest of 
citrus, is reported from Florida. These beetles eat the young shoots to such an 
extent that recently set trees are sometimes killed back one foot. 
The Australian tomato weevil is reported for the first time from 
Mobile County, Alabama. 
An aphid of a species not yet .determined is reported as appearing on 
orange in great numbers in portions of southern Florida and doing important 
damage.
