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

Citrus Rust Mite: 71% of groves infested (Norm 65%); 46% economic (Norm 43%).
Population again decreased but is still above normal and in the high range. Decrease on
leaves will continue but an increase is expected on fruit. Highest districts are South (2.04)
West (1.92) and Central (1.58).
Citrus Red Mite: 22% of groves infested (Norm 29%); 2% economic (Norm 14%).
Population is the lowest for February in 21 years of record. Little change is expected.
All districts will remain in the low range.
Texas Citrus Mite: 17% of groves infested (Norm 30%); 7% economic (Norm 11%).
February population is the lowest since 1962 and will go lower. Very low levels of in-
festation will continue in all districts.
Six-spotted mite is below normal abundance and in only a few groves, but will gradually increase.
Glover Scale: 69% of groves infested (Norm 78%); 2% economic (Norm 13%).
This scale will decrease and remain at low level through March. Highest district is
South (.87).
Purple Scale: 74% of groves infested (Norm 74%); 2% economic (Norm 8%).
Population is below normal and will remain of little importance despite a temporary
increase in March. Highest district is West (.94).
Chaff Scale: 43% of groves infested (Norm 54%); 1% economic (Norm 6%).
Yellow Scale: 31% of groves infested (Norm 61%); 1% economic (Norm 10%).
These two scales are below normal abundance and will be unimportant in all districts,
Black Scale: 46% of groves infested (Norm 28%); 21% economic (Norm 11%).
This scale will continue to decrease but it is still more abundant than in any prior
February on record. High districts are East (1.30) and Central (1.06); others are low.
Snow Scale: 30% of groves infested; 22% economic.
Population is higher than in any prior month. Slight increase is expected.
Whitefly larval and pupal stages will decrease; adults and eggs will increase to above normal
numbers. Highest district is East (1.87).
Aphids are appearing as light infestations in scattered groves. Strong increase is expected.
Spray Notes: If sprays are necessary to control aphids or rust-mites in March or April, apply
them before bloom buds start to open or after 2/3 of petals have fallen. Nutritional materials
may be included in these sprays.
