INSECT PESTS OF CIGAR-TYPE TOBACCOS ol 
air-slaked lime has been reported as being very effective in control- 
ling slugs. When they are attacking a plant bed the recommended 
dosage 1s 4 pounds of lime to 100 square yards. ‘To protect newly 
set tobacco plants a dosage of from 5 to 10 pounds per acre is 
recommended. Late afternoon is believed to be the most suitable 
time for application. 
The cabbage looper (Autographa brassicae (Riley)) frequently 
causes slight injury to sun-grown and shade-grown tobacco. The 
light greenish caterpillars 
feed on the leaves and cause 
injury somewhat similar to 
that produced by small horn- 
worms. ‘The application of 
remedies for the hornworm 
and flea beetle assists in con- 
trolling the looper. 
The spotted cucumber beetle 
(Diabrotica duodecimpune- 
tata (F.)) feeds to a limited 
extent on tobacco in this re- 
gion. 
A large, dark-colored, hairy 
caterpillar (Callarctia phyl- 
lira (Drury) ) infrequently at- 
tacks young tobacco. The 
injury to the plants is very 
similar to that caused by cut- 
worms. 
Larvae of the crane flies 
(one or more species of 77ipu- 
la) occasionally attack newly 
set tobacco plants in this re- 
gion. These tough, black or 
grayish maggots feed on the 
stems and leaves. Feeding on 
the leaves is largely confined 
to those buried or partly bur- 
ied at the time of transplant- 
ing and to the leaves which lie 
on the surface of the soil. 
The greenhouse whitefly . 
(Trialeurodes vaporariorum  Ficure 56—Tobacco leaf showing the char- 
(Westw.)), the green peach acteristic injury caused by the tobacco 
aphid (Myzus persicae splitworm. 
Ce ), and the potato aphid 
(Macrosiphum (Illinoia) solanifolii (Ashm.)) have been found feed- 
ing on tobacco, but in very few instances have they been observed 
to have caused severe damage. 
The field crickets Gryllus assimilis (F.) and Nemobius ambitiosus 
Scudd. are minor pests of plant beds and of newly set tobacco in this 
region. ‘They are found most frequently under piles of old decaying 
stalks or trash. Poisoned bait applied for the control of budworms 
and cutworms also assists in the control of the crickets.
