GENERAL FE-EDER.S 
GRASSHOPPERS (Acrididae) 
Worth Dakota. J. A. Munro (April 2l): As high as 25 percent mortality of 
overwintered eggs has been found in light sandy soils in severe drought- 
stricken areas of the State, while in the heavier types of soil the 
mortality is very low. Apparently the mortality is due to desiccation 
of the eggs in abnormally dry soil. 
Mississippi. K. L. Cockerham (April 16): On April 16 a report was received 
at this office that' a serious outbreak had occurred on two truck farms 
4 miles north of Biloxi. An investigation showed nymphs quite numerous 
in grassland around the edges of the truck field and serious damage to 
tomato plants set in the fields near the grassland. Poisoned bait was 
applied on these truck farms in an effort to prevent further serious in- 
jury. Although the specimens have not been identified, they are believed 
to be nymphs of Schistocerca americana Drury. 
Nebraska. M. H. Swenk (April 15): A threat of more or less damage at this 
time involves two or three principal areas in the State. As during the 
past three seasons, the most serious threat lies in north-central Nebraska, 
•'along the Niobrara River and the South Dakota boundary. This area in- 
cludes the northeastern corner of Cherry County from Crookston east, all 
of Keyapaha and Soyd Counties, the northern sections of Brown and Rock 
Counties near the Niobrara, about the northern half of Holt County, all 
of Knox County, and the northern part of Cedar County. In portions of 
this area grasshoppers were very injurious last year and eggs are now , 
present in numbers as high, as 25 eggs to the square foot. Next to this 
north-central area, an area in Keith and Deuel Counties and western 
Perkins County seems to hold the threat of most serious injury. A third 
district where the threat seems less severe includes southeastern Rock 
County, with major sections of Loup, Garfield, Wheeler, and surrounding 
counties. 
Arizona. C. D. Lebert (April 18): Scouting records to April 10 show the 
infestations of Melanoplus mexicanus Sauss. in the Salt River Valley to 
be as follows: 85,000 acres, light infestations; 10,000 acres, medium in- 
festations; and 1,500 acres, heavy infestations. Winged adults were 
noticed April 6. Actual crop damage is becoming apparent in alfalfa 
fields and in a few young citrus plantings adjacent to alfalfa fields in 
the Mesa area. Farmers are using poisoned bran mash in these areas to 
some extent. 
Idaho. C. Wakeland (April 25): Melanoplus bivittatus Say began hatching at 
Emmet t, Gem County April 11. Economic species are not yet hatching in 
other parts of Idaho. Heavy outbreaks are expected in southeastern Idaho 
and in Jefferson County. An egg survey in Caribou County showed as many 
as 8,000 eggs of Camnula pellucid?. Scudd. per square foot of sod. All of 
the heavily infested counties are completely organized for control. 
Orders have been placed for 23 carloads of poisoned bait. Some of the 
districts most heavily infested last ye?„r will show decided decreases
