NOTE: Only pests or conditions of general or current interest are reported.
Forecasts are for 1 month in advance unless otherwise indicated.

Rust Mite: 74% of groves infested (Norm 58%); 56% economic (Norm 35%).
Population decreased but is still in the high range and much above normal for
February on both leaves and fruit. It will continue near the current high level.
Highest districts are South (2.00) West (1.80) and Central (1.68).
Texas Citrus Mite: 37% of groves infested (Norm 26%); 13% economic (Norm 8%).
Population is in the low range and slightly above the February normal. Moderate
increase is expected. Highest districts are East (.86) and South (.75).
Citrus Red Mite: 37% of groves infested (Norm 34%); 10% economic (Norm 12%).
Population is low and near normal for February. Increase is expected. Highest
districts are East (.90) and Central (.50).
Six-spotted Mite: 7% of groves infested, 1% economic. Slight increase is expected.

Glover Scale: 73% of groves infested (Norm 80%); 7% economic (Norm 20%).
Population is below average and moderate. Increase is expected. Highest districts
are East (1.04) Wast (.93) and South (.81).
Purple Scale: 67% of groves infested (Norm 79%); 2% economic (Norm 11%).
This scale will remain below normal and in the low range. Highest district is
East (.82).
Yellow Scale: 65% of groves infested (Norm 63%); 1% economic (Norm 15%).
Population is below normal and in the low range but will increase. Highest dis-
trict is East (.86).
Black Scale: 42% of groves infested (Norm 28%); 20% economic (Norm 13%).
Population was above normal for February. It is expected to decrease to the low
range and be of little concern through March. Highest districts are Central (1.30)
and East (.82).
Snow Scale now infests 16% of groves, a record high number for February. Further in-
crease is expected.

Whitefly: 74% of groves infested; 15% economic. Little change is expected from the
current low level normal for February.

Aphids have been retarded by cool weather but may be expected to increase rapidly the
latter part of March.

Spray Notes: The continuous cool weather of February has slowed insect and mite activity
and pests are not expected to be a widespread problem in March. March is also the month
for peak bloom of most varieties in most districts. Spraying operations should be
avoided during the blooming period.
