Missouri. Leonard Baseman (April 7), "Just before the Easter freeze, March 
27 and 28 and also since, the plant lice on wheat and oats have 
attracted much attention especially in Newton, Jasper and Vernon 
Counties. In that part of the state a hail storm accompanied the 
Easter freeze which put a decided check on the plant lice. Two 
fields of wheat in Newton County were reported destroyed by the 
lice and a number in Jasper and Vernon Counties seriously damaged. 
The first reports seemed to indicate that the Southern grain louse, 
Toxcptera gra minurri was responsible for the injury. However, field 
collection of lice and samples received at the office show that one 
or perhaps two species of Macro siphur a were moot abundant with Sj-oho-... 
coryne avenae as Saciosep second-, in ciuy a few cases did Toxoptera 
graminum appear in the collections."

Tennesse. Geo. G. Ainslie (B.E., April 14). "I have never seen so much Joint 
Worm as there is this year. Almost every field visited has an 
appreciable amount and is some places it is very severe-. '"'-en 
we first fount it the progeny of the minutur,. adults were abcufi half 
grown in the littlw deformed tillers. They are now rapidly pupating 
and unless something happens to prevent their emergence and ovipo- 
sition it seems certain that the next generation will be large enough 
to take practically every stem. The field seems generally infested 
too, not in patches but uniformly throughout. A great deal of wheat 
land was replanted to wheat last fall, and here of course no migration 
is necessary."
