growers of Florida that there was a native 
insect ready to infest howardi upon its 
arrival hare. Otherwise it would have 
been an exceedingly dangerous foe, be¬ 
cause of its ability to spread rapidly, its 
exceedingly sticky and copious honeydew, 
and its comparative immunity to the at¬ 
tacks of the fungi which parasitize the 
other whiteflies. 
The other insect is the 
COTTONY CUSHION SCALE 
About the only new thing we have to 
report concerning this insect is its distri¬ 
bution in the state. 
It was introduced into the Pinellas sub¬ 
peninsula over twenty years ago, but until 
the writer found it in Tampa in 1911 it 
had not been reported from the mainland 
of Florida. During the past two years it 
has been spreading rapidly. Its present 
distribution is shown by the map. 
This insect can be controlled by spray¬ 
ing in connection with its native enemies, 
chief among which is the common thice- 
stabbed lady-beetle, but the way to control 
it is by the introduction of the Australian 
lady-beetle. This insect (exhibit) is also 
getting pretty well distributed over the in¬ 
fected area. I am endeavoring to keep 
track of the colonies of the latter and am 
usually in a position to advise the owners 
of infested groves as to where they can 
procure the beetles. At the present time 
a party in Leesburg is attemping to raise 
the beetles in confinement so as to con¬ 
stantly have a supply on hand. 
Discussion. 
Mr. Thompson: The red scale spoken 
of there; is that what is sometimes 
callecf the Cuban scale? 
Mr. Watson: No; it is the common 
red scale; the Florida red scale. The pink 
fungus is for that only. 
Mr.-: I would like to know if 
any fungus has yet been discovered that 
attacks the mango scale. 
Mr. Watson: So far as I know, we 
have found no fungus. It seems to be a 
parasite. 
M*r. Prouty: I would like to ask about 
the fungus growth down at Arcadia. 
M,r. Watson: I was speaking of the 
whitefly; not the fungus. You never have 
had a severe infestation at Arcadia—just 
a few. The only severe infestations are 
at Tampa and Lakeland. 
Mr. Baker: I would like to ask what 
he knows about the infestation of the 
woolly whitefly at Lake Okeechobee. 
Mr. Watson: Nothing, except some 
specimens from Ritter. 
Dr. Berger: I would like to say a 
whole lot of things I could say about that. 
It has no business there at all. I want to 
apply to you as a body, gentlemen, to re¬ 
port all violations of the nursery inspec¬ 
tion law. Report them to> me. I know 
well enough on the Caloosahatchee river 
there are contraband nurseries shipping 
stuff up and down that river, regardless 
of any law. There are a few nurserymen 
down there abiding by the law who have 
been inspected. 
Now, what business has the woolly 
whitefly got on Lake Okeechobee? Some 
man ignored or maliciously defied the 
law and simply carted some dirty stuff up 
there. 
You can do more than I can. You are 
right with these people, some of you, all 
the time. When you see those violations 
you can simply tell those who are defying
