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

Rust Mite: 70% of groves infested (Norm 57%); 53% economic (Norm 36%).
Population is much above the February average and is in the high range. It will
remain high. District indexes are South (2.22) West (2.00) Central (1.40) North (1.27)
and East (1.00).

Citrus Red Mite: 56% of groves infested (Norm 31%); 29% economic (Norm 13%).
Population is above normal and near the high range. Increase into the high range
is expected. Highest districts are North (1.33) West (1.30) and Central (.87).

Texas Citrus Mite: 44% of groves infested (Norm 26%); 26% infested (Norm 8%).
Population is at the highest level for February in 15 years of record. It is in
the moderate range at present but further increase is expected. Highest districts are
West (1.30) and North (1.00). Texas citrus mite is less abundant than citrus red mite.

Six-spotted mite is still below average and very scarce.

Glover Scale: 83% of groves infested; 18% economic. Population is above normal and in
the high range. Slight decrease is expected. Highest districts are East (1.22)
Central (1.20) and South (1.15).
Purple Scale: 78% of groves infested, 8% economic. Population is below average and in
the moderate range. Little change is expected. Highest district is Central (1.00).


Yellow Scale: 69% of groves infested, 15% economic.

and East (.91).

Highest districts ar, Con-rml /1 17~,.,


Chaff Scale: 60% of groves infested, 5% economic. Population is much below normal and
in the low range: Slight decrease is expected. Highest district is East (.74).

Black Scale: 43% of groves infested, 16% economic. Population is above the normal low
level for February. It will remain in the low range. Highest districts are East (.83)
and Central (.83).

Whiteflies are near average abundance with 64% of groves infested.

Mealybug is present at low level and is decreasing.

Spray Notes: Except for rust mite control, there will be little need for sprays in the
next month.
Aphids will appear in scattered groves in March. Aphid control usually is economical
only for young groves and for susceptible fresh fruit varieties such as Temple. Demeton
(Systox) at 5 pints per 500 gallons will provide good control of aphids and can be ap-
plied to trees with fruit, providing the fruit is not harvested within 21 days after
application. Apply the spray after aphids appear but before they curl the new leaves.
See the 1967 Florida Citrus Spray and Dust Schedule.
