entomologists, and also has the cooperation of other federal 
and state agencies for reporting outbreaks of injurious insects. 
Finally, it becomes the duty of all growers to keep a sharper 
outlook than ever over their crops, to report the first symptoms 
of insect depredations and to send specimens, in order that 
no efforts may be omitted to save the crop, and that they may 
be doing their full share in the “preparedness” program.

SOME INJURIOUS INSECTS 
The whitefly (Dialeurodes citri) has received a bad jolt this 
season over most of the State. The February freeze defoliated 
the trees, taking the larvae down with the leaves to perish on 
the ground as the leaves dried out. But let no grower flatter 
himself that the pest has been eradicated. Hosts other than 
citrus, such as wild olive (Osmanthus americanus), japonica, 
privet, etc., carried thru enough for “seed.” The larvae were 
not. directly injured by the cold but came thru in good shape 
on any plant whose leaves did not drop. - With plenty of new 
leaves on which to breed, the third generation of larvae due in 
August and September, will, doubtless, in many localities be- 
come sufficiently abundant to make spraying imperative. Don’t 
waste your money on ‘“‘cure-alls.””’ Use the parasitic fungi dur- 
ing the rainy season; after that the paraffin oil sprays. See 
Circular 168,-U. S. Bur. Ent. or Bul. 123, Fla. Age. Exp. Sta. 
The Boll Weevil will “hit the trail’ for his annual “hike” in 
August. He will probably get about to Ocala this fall unless 
someone has given him a “lift”? in some cotton seed. 
Some scattering specimens of the Fall Army Worm (Laphyg- 
ma. frugiperda) have been observed about Gainesville. This 
may or may not mean an outbreak later. This insect, also called 
the Southern Grass Worm, attacks especially plants of the grass 
family. Spray plants with lead arsenate, using two pounds to 
fifty gallons of water. 
In August a pretty, velvety looking caterpillar will probably 
be found defoliating the vines in many places. It is the Sweet- 
potato Caterpillar (Prodenia Sp.). Spray as for the Fall Army 
Worm or use the cut-worm bait.
