THE I'INK BOLLWOBM. 
in Arizona, on account of the comparative freedom of the cotton 
grown there from insect injury and the definite indication that the 
Stat.' will soon be able to produce large quantities of cotton of em 
rior quality which can not be grown in other parts of the count] 
O n j^y i, 1913, the Federal Horticultural Board promulgated 
quarantine against cotton seed from all foreign countries, with 
object of preventing the invasion of the ;>ink bollworm. Since this 
quarantine has been in effeel several shipments of cotton seed 1 
been intercepted. All wen- found t<> be infested by the pink boll- 
worm; one shipment, which was to he forwarded to Arizona, Bhowed 
an infestation of 20 per cent. 
In this connection it may be stated that there ifi no longer any need 
for importing cotton seed from Egypt, since there is an amplesupplyof 
well-selected and 
cfimatized seed a\ ail- 
c T able in Arizona. 
DISTRIBUTION. 
The pink bollworm 
was described oti 
nally from India in 
1st;!. Since that time 
it has been found more 
or less generally wide- 
spread in India, I 
of Egyptian cotton showing typical Injuries made by the j (m g nrmftj Straits 
ink bollworm. Much enlarged. (Origin ' 
ttlementf . pt, 
British East Africa. German East Africa, Nigeria, Sierra Leone, and 
the Hawaiian Ishuuls. In the Hawaiian Inlands it was undoubtedly 
introduced in cotton seed from India. There is also a doubtful 
record of the occurrence of the species in Japan. 
The question has been raised as to whether the pink bollworm is 
not already established in the United States. Vm- several reasons it 
seems certain that this is not the case. Since the boll weevil invaded 
the country planters have paid very especial attention to the in- 
found on the cotton plant. Each year hundreds of specimens mis- 
taken for the boll weevil are sent to the Department of Apiculture 
and to State entomologists. Since the pink bollworm might easily 
be mistaken for the boll weevil by planters it is altogether likely that 
it would have been bmnd if it were established at any point in the 
United States. Moreover, the chances of introduction have been 
small until recently, because the Egyptian crop has not been generally 
infested until within the. Last few years.
