LEAFHOPPERS INJURING THE FOLIAGE 195 
In meadows where severe attack is noted the wisest measure is to cut 
and then burn over, although this probably will kill the grass roots. 
In moist weather chinch-bugs are killed in large numbers by a fungous 
disease. Attempts have been made to propagate this artificially, but 
the measure cannot be depended on with sufficient certainty in times of 
severe attack. 
The Tobacco Suck-fly (Dicyphus minimus Uhl.) 
In Florida a black, sucking bug, one eighth of an inch long, with long 
greenish legs, attacks the leaves of tobacco and by its punctures spots the 
leaf, making it wilt, turn brown, and crack. The younger stages feed in 
similar fashion on the under sur- 
face of the leaf. There are several 
generations annually. Spraying 
with tobacco extract will kill the 
immature forms and check the pest. 
The Beet Leafhopper (Eutettix 
tenella Baker) 
A very small, active insect, one 
of the ‘leafhoppers,”’ swarms on 
the foliage of sugar beets in count- 
less myriads. The leaves of plants 
attacked usually exhibit a char- 
acteristic appearance, commonly 
known as ‘curly leaf.” The edges 
are rolled in, the leaf surface is 
wrinkled, and growth is stunted. 
As a consequence the beet puts 
out many fibrous roots, does not 
reach normal size, and its sugar 
content is low. 
The adult is very small, whitish 
or pale green, winged, and is pro- — Fyg, 243.— Beet leaves curled by
