Cankerworm eggs "began hatching in the East in May and in the 
Southern States early in March. Serious damage to "both orchards and 
forest trees was reported from New England, the Middle Atlantic States, 
and the last Central States. In June considerable defoliation took 
place locally in W?stern Maine, Massachusetts, eastern New York, nor- 
thern New Jersey, and northeastern Pennsylvania. Other infestations 
appeared in eastern Ohio, northern Indiana, and Illinois, extending 
into Wisconsin, Minnesota, Iowa, and Nebraska. 
FOREST TENT CATERPILLAR 
Late in April a very heavy infestation of this insect occurred 
in southern Mississippi, where, in many areas, swoetgum and oak were 
completely defoliated. As the season advanced reports of serious 
damage were received from Utah and Washington, and in June almost un- 
precedented rutbreaks occurred throughout New England and New York, 
One defoliated area in the State of Maine included 60,000 acres of 
mixed timber. Throughout the East damage was particularly severe on 
sugar maple and elm. The outbreak extended westward ever northern 
Michigan into Minnesota. 
JAPANESE BEETLE 
Insofar as the status of the Japanese beetle in the area of 
general or continuous infestation is concerned, the year 193& is 
notable in several ways. For the first time since the beetle has 
been known to occur in the United States, there was a very consider- 
able mortality of the grubs, resulting from the extreme cold weather 
in January and February, coupled with the lack of a sufficient blanket 
of snow covering the ground. Heavy larval mortality occurred in parts 
of southwestern New Jersey, the southeastern corner of Pennsylvania, 
northern Delaware, and in the northeastern corner of Maryland, the de- 
struction of grubs in this area ranging from a few to as high as 50 
percent. During previous winters, grub mortalities have seldom run 
higher than 10 percent throughout this area. Throughout other por- 
tions of the area of continuous infestation, however, larval mortality, 
in general, did not run appreciably higher than the average of previous 
years. As a consequence of the reduction in grub population late in 
the winter, there was observed during the slimmer beetle season a geru* 
eral decreaso in both beetle abundance and plant injury in the same 
portions of New Jersey, Pennsylvania, Delaware, and Maryland, with 
some localized points of heavy beetle abundance and plant injury where 
winter conditions were more favorable. On the other hand, throughout 
those parts of the area of general infestation lying outside this re- 
stricted area, there was observed the customary general increase in 
beetle abundance and plant injury which was anticipated, This in- 
creased abundance and injury -"as particularly notable in sections 
north and northwest of Trenton and in parts of Salem and Cumberland 
Counties, in New Jersey; in New Castle County, south of Wilmington,
