The young hoppers developed rapidly and, in spite of control operations, moved 
into cultivated crops* 
Prolonged cold rainy weather in late May and early June in the Northern 
Great Plains delayed growth of the nymphs, interfered with control operations 
and cons iderahly reduced infestations in. the eastern part of the infested area* 
Adults were maturing generally "by the last of June, Small local flights occurre* 
in Nebraska and Kansas, More extensive flights occurred in eastern Montana, 
where all green vegetation was devoured. About 25,000,000 acres was baited, and, 
although the average percentage of damage to crops was small, crops in some fiel. 
were completely destroyed. B. longipennis -"as .so successfully controlled, that ' 
it is believed that with 1 more year of intensive baiting the outbreak will be 
practically eliminated. The egg survey carried on in the fall showed a marked 
decrease in the extent and severity of the infestations. A map based on the sur. 
vey is appended. 
CHINCH BUG ‘ 
The seasonal development of the chinch bug during 1939 largely duplicated 
that of 1933* The threat of rather general moderate-to-severe infestations from 
central Ohio across Indiana, Illinois, southern Iowa, most of Missouri to south- 
eastern Nebraska, eastern Kansas, and eastern Oklahoma, •’•’as mostly removed by the, 
cold wet spring, which delayed flight from hibernation quarters to the small 
grains and later destroyed most of the nymphs of the 1 spring brood. As a result, 
damage was restricted to comparatively few scattered localities throughout the 
area* Some local damage was also reported from Michigan, Wisconsin, South Caro- 
lina, and Texas. However, as a result of drought over the area late in the 
summer and fall, the second-brood nymphs (and third-brood nymphs as reported fror 
Oklahoma and Kansas) had unusually favorable condition 0 for completion of their 
development and subsequent flight of adults to winter hibernation quarters. 
Early returns from a survey covering the chinch bug area, which is not yet com- 
pleted, and information from various State entomologists, indicate sufficiently 
heavy concentrations of bugs present in winter hibernation from north-central 
Ohio across north-central Indiana and Illinois, central and southern Iowa, most 
of Missouri, to southeastern Nebraska, eastern Kansas, and Oklahoma, to produce 
widespread raoderate-to-s evere infestations next spring and early summer, pro- 
vided weather conditions ore favorable to the bugs. Illinois reports the largest 
numbers of bugs in winter quarters in some localities since the fall of 1933*

MORMON CRICKET 
The first hatch of the Mormon cricket was reported on March 10 in Oregon 
and on March l4 in Nevada. After these dates hatching was reported as continu- 
ous and even, over the entire infested area until the last of April, when most 
of the eggs had hatched. Severe infestations developed in most of the infested 
area; however, material damage to cultivated crops was prevented by intensive 
control operations. Mormon crickets caused unusual defoliation of young ponder- 
osa pines near the lower edge of pine growth on the Whitman National Eorest. In 
addition to stripping the foliage from up to 10 or 12 feet high, the migrating
