14 SPRAYING PEACHES, 
weevil,” “‘little Turk,” ‘‘curculio,’”’ ete. The name here used, how- 
ever, is perhaps best fixed in literature on economic entomology and 
has been adopted for this species by the American Association of 
Economic Entomologists. 
The plum curculio is a native American insect and fed originally, 
as it feeds at the present time, on wild plums and other wild fruits, 
especially Crataegus. Its injuries were noted as long ago as 1736, 
and it was the subject of an extended article published in 1804. Our 
early horticultural litera- 
ture abounds with refer- 
ences to its depredations, 
especially to plums, which 
were apparently grown 
with the greatest diffi- 
culty. 
So far as is known, the 
plum curculio is still con- 
fined to North America, 
ranging from southern 
Canada south to Florida 
and Texas and west to 
about the one hundredth 
meridian. It appears to 
be restricted in its west- 
ward spread by the more 
arid climate of the Great 
Plains region. It is prob- 
ably present throughout 
its entire area of distribution, but is especially abundant in the 
Central and Southern States. 
Fia. 6.—Peach infested with curculio larva, or grub. 
FOOD PLANTS AND CHARACTER OF INJURY. 
Practically all stone and pome fruits, such as peaches, plums, apri- 
cots, nectarines, cherries, apples, pears, etc., are used by the curculio 
for feeding and egg-laying purposes. Injury is done by both the 
adult and larva. The former punctures the fruit in feeding and in 
ege laying, and the grubs live within the fruit and spoil it for market 
or other purposes. The character and extent of injury vary with 
different fruits, and while the present paper deals with the insect as 
an enemy of the peach the statements here made are fairly applicable 
to other stone fruits, such as plums, cherries, apricots, and nectarines.
