_ ALL VARIETIES OF AVOCADO SUBJECT TO INSECT 
ATTACK. 
VOCADO GROWING was established a number of years earlier 
in Florida than in California, and for this reason considerably 
- more is known about this fruit and its insect enemies in Florida than 
on the Pacific coast. To those who are growing the avocado in 
California, however, a discussion of its insect pests in Florida, 
where the investigations upon which this paper is based were con- 
- ducted, may not be without interest. Although conditions must 
largely decide methods and practices in the control of avocado pests, 
_ the experience gained in another region can not fail to throw light 
on certain questions which may arise in California. 
_ The avocados now grown in Florida are mainly varieties of the 
West Indian race, although varieties of the Guatemalan type are 
_ fast gaining in popularity among growers, due to the fact that 
_ they will stand a somewhat lower temperature. The Guatemalan 
_ race, however, has been grown sufficiently in Florida to show that 
for the most part the insects which attack the West Indian race of 
avocado will adapt themselves to the hardier Guatemalan varieties 
as well. While some of these insect enemies may have been intro- 
duced, others probably have long been present on native vegetation 
and have recently adapted themselves to the newly imported and 
more attractive avocado.
