INTRODUCTION 
/ 
The winter of 1932-33 was generally milder than the average, 
with deficient rainfall in some sections, especially in the Southwest 
and the Great Plains. January was warm and dry, especially in the 
upper Missouri Valley; February was nearer normal, with some sudden 
and severe cold waves, and unusual cold in the mountain and Pacific 
States. 
Spring was somewhat above normal in temperature, especially 
March. Rains were generally abundant in the eastern half of the 
country., and delayed farm work in the eastern part of the Corn Pelt; 
in many parts of the West the moisture deficiency was unrelieved. 
June was warmer than normal, especially in the Plains States, 
and continued drought in that region reached the stage of crop dis- 
aster in many localities. Many temperature records were broken. 
Farther east conditions were nearer normal, though rainfall was 
variable and often light. July was above normal in temperature ex- 
cept along the Atlantic coast; rainfall was quite variable, but more 
plentiful than in June. 
Late summer and early fall were marked by some relief from 
drought in the plains region and by an unusual number of tropical 
hurri canes, some affecting our eastern coast. These conditions are 
reflected in insect pest abundance in many cases, as brought out in 
the following pages.
