OUTSTANDING- ENTOMOLOGICAL FEATURES IN THE UNITED STATES 
EOR THE PERIOD FROM NOVEMBER 1, I92H, to. APRIL 1, 1925 
With this number the Survey opens the fifth Volume of its t . Bulletin,-. .'. 
"!7e note with extreme gratification the rapid fruition of our efforts to.- ■ » 
standardizo methods of estimating insect ''abundance for : Survey, work. .; . ,' 
In this initial number, of -the' volume is a very extensive paper •' 
tabulating minutely ' observations on the abundance -of grasshoppers under varying 
meteorological conditions. ■There- is also a detailed estimate on the relative' 
abundance; of the Hessian -fly over the'' southern Middle Atlantic States. Under 
the San Jose scale is given the results of a very definite. ; count made -in ':■. 
connection with investigations of the effect. ; of-. severe ; winter temperatures . 
on this insect in Missouri. .: Farther on is "the cotton -boll weevil count 
made in Louisiana, arid a few pagos "beyond this a report on- very definite 
estimates of the damage done "by the sugarcane "borer. Thus on, throughout ,,:'.'■ 
the Bulletin, can "be observed a decided difference in - the" type of note to that ;"••' 
recorded in Volume 1, when- the .'.Survey -was' just starting, its work and feeling 
its way for a "better method of procedure. 
The general feeling among: entomologists that the "suggestion made in 
launching the Insect Pest . Survey that its Ultimate aim should "be entomological 
forecasting seems to have changed from a rather skeptical tolerance to an-, 
active interest. This is evidenced "by the many papers that have appeared 
during the last three years' attempting the correlation &f meteorological 
factors with insect, abundance. , ; .r, These correlations, of course, would be wasted 
effort if there 1 was not the hope that they might load to an interpretation 
of the effect of environmental factors on insect development which in turn .; 
might lead eventually to a forecasting of the' probable future development -.. 
of a given pest. • - ":'.'- ' \-Y- • , 
The grasshopper situation in the Southwest is threatening, despise 
newspaper reports to the effect that the grasshopper eggs had been killed 
by cold weather. .'..'. .;.:■''>• •"'.' • ■• . ' . - , 
The Hessian fly situation as a whole is not serious. Over the Middle 
Atlantic States fall counts show a decided decrease over 19 2 3. In the Middle 
and Western States late planting campaigns seem to have been extremely 
successful. 
The chinch bug situation is generally satisfactory. Reports of decided 
decrease in numbers are being received from practically the entire belt. 
The green bug has not yet given any evidence of being a dangerous 
pest this spring.
