APHIDS (Aphildae) 
General. F. F. Bondy and C. F. Rainwater (May): In a United survey made in 
Hay, five species of aphid s were found on cotton along the Atlantic sea- 
"board. The green cotton root louse ( Anur aphis maidi~radic? Forbes) was 
the most widely distributed, having been found in every section of South 
Carolina, except the extreme west and northwest, and in the eastern part 
of Georgia, llorth Carolina, and southeastern Virginia. In fact, it was 
found causing injury to cotton in every section scouted except northern 
Florida. The white cotton root louse ( Trifidaphis phaseoli Pass.) was 
observed in many parts of South Carolina, in eastern ITorth Carolina, and 
in southeastern Virginia. It becomes more numerous along the seaboard 
in the northern part of the Cotton Belt and reduces the stand in areas 
where found. The brown cotton root louse ( Rhopal o siphum sp.) was found 
in certain areas of Virginia, North Carolina, and South Carolina. In 
every instance but one it was associated with one or both of the other 
root aphids. In the one field where this species was found alone the 
injury was comparable to that caused by a heavy infestation of either of 
the other species. The aerial forms found attacking cotton were Aphi s 
medicaginis Koch, and A. gossypii Glov. A. medicaginis was by far the 
more serious and was more generally distributed in Georgia, South Caro- 
lina, and ITorth Carolina, Its attack is almost always confined to the 
terminal buds and it is seldom seen on the large leaves, except in cases 
of extremely heavy infestation. A, gossypii was found only in scattered 
areas of the States visited, usually on the larger leaves of the cotton. 
Mississippi. C. Lyle (June 22): Plant lice are rather abundant on cotton 
throughout the State, but ladybird beetles are unusually numerous and 
are expected to easily hold the lice in check. 
Alabama* J. M. Robinson (June 20): The cotton aphids have been moderately 
abundant in Auburn, but are being controlled by parasites and predators. 
In the Tennessee Valley near Huntsville and in north-central Alabama 
these insects have been very numerous. As a, result of the parasites and 
predators, particularly convergent ladybeetles ( Hippodamia c onvergens 
Guer.) the aphids ere being controlled. 
COTTON PLEA HOPPER ( Psallus seriatus Reut.) 
Texas. H. J, Reinhard (June 22): Injury to cotton by the cotton flea hopper 
seems to be quite general in McLennan, Bell, and Burleson Counties. 
A CRICKET ( Anurogryllus muticus DeG. ) 
Mississippi. M. L. Grimes (June 22): Injury to cotton by A. muticus was 
observed on June 5 at Heidelberg,
