Complaints about the striped cucumber beetle, Diabrotica vittata, 
began to come in by the lstof May. Young plants of cucumber, squash, 
cantaloupe, and watermelon were attacked and the loss was considera- 
ble. In one case, as many as three replantings are reported to have 
been made. Beetles were first observed at the station April 25, and 
they have been quite abundant thus far, feeding on the bloom, foliage, 
and fruit of squash, cucumber, and cantaloupe. Larve have been inju- 
rious, feeding on the rind of cantaloupes where in contact with the soil, 
causing a roughening or warting of the skin. 
Still another chrysomelid has been destructive in Georgia this year. 
This is the Colorado potato beetle, Doryphora 10-lineata. An effort was 
made to determine its present distribution in the State, and from the 
data collected, it would seem that a straight line drawn from Columbus 
to Savannah would separate to the north the area most seriously infested. 
Beetles appeared from winter quarters in the neighborhood of Griffin 
about April 20; adults and larve are now abundant on Solanum caro- 
linense, feeding in company with Doryphora juncta. The intermating of 
these two species was frequently noticed this season, but eggs of hybrid 
origin failed to hatch and were doubtless sterile. 
Early in the spring larve of Diabrotica 12-punctata occasioned con- 
siderable injury by boring into the stalk just above the roots of young 
field corn. This larva is much worse on low moist lands than on uplands, 
and it is the usual practice of farmers to plant two or three weeks later 
on bottoms than on uplands. 
Probably our most serious grape pest at the station is the Allorhina 
nitida. ‘They were very abundant last year, and even more so this 
year. Beetles appeared this season June 18. Early in July such early 
grapes as Presly, Early Ohio, and Janesville were attacked and badly 
eaten into. The beetles seemed to increase in numbers until the latter 
part of July, and all the season through probably destroyed 15 per cent 
of the grape crop.- Soon after their appearance a poisoned bait of bran, 
sweetened with sugar, was placed upon sticks in pans where they were 
in the habit of flying thickest, but, so far as obsérved, the bait was not 
eaten by the beetles. 
Cotton planters from several localities in Georgia, and from South 
Carolina and Alabama, have sent in the elaterid Monocrepidius vesper- 
tinus, with the statement that the beetles were eating into the young 
squares of cotton, and doing very serious damage. Theinsect has been 
quite abundant on the grounds of the experiment station, but, so far as 
I have observed, has not been injurious to cotton. I have very fre- 
quently observed them feeding on the excrement voided by the boll 
worm, and they have been to a great extent associated with this insect, 
and, in general, have had the habits of scavengers. Considerable num- 
bers of the beetles were caged at different times, with stems of cotton- 
bearing squares and leaves, and in but one instance was the cotton 
attacked, and then very sparingly.
