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: 68% of groves infested (Norm 65%); 44% economic (Norm 43%).
Population decreased and is now only slightly above normal but still in the high range.
Decrease to moderate level is predicted. Highest districts are South (2.05) West (1.64) and
Central (1.47).
Citrus Red Mite: 19% of groves infested (Norm 40%); 2% economic (Norm 15%).
Population is the lowest for March in 21 years of record and will remain very low in
all districts.
Texas Citrus Mite: 17% of groves infested (Norm 31%); 5% economic (Norm 12%).
Population is near the very low level of 1970 and will remain unimportant in most dis-
tricts despite a predicted increase. Highest district is Central (.41).
Six-spotted Mite: 5% of groves infested; none economic.
Population is below normal and very low but will increase in scattered groves.
Purple Scale: 80% of groves infested (Norm 76%); 3% economic (Norm 8%).
Population is near normal. It is in the moderate range in all districts. Increase is
expected. Highest district is North (.93).
Glover Scale: 70% of groves infested (Norm 80%); 2% economic (Norm 13%).
This scale is at the lowest March level since 1963. Population is expected to increase
from the low to the moderate range. Highest district is East (.86).
Chaff Scale: 45% of groves infested (Norm 56%); 1% economic (Norm 7%).
Population will remain below normal and low. Highest district is South (.71).
Yellow Scale: 34% of groves infested (Norm 61%); none economic (Norm 9%).
Population is at the lowest March level since 1964 and will remain low in all districts
despite the slight increase expected.
Black Scale: 44% of groves infested (Norm 26%); 24% economic (Norm 10%).
Statewide population averages above the March normal. At present, populations vary greatly:
East (1.27) Central (.97) West (.56) North (.36) and South (.29). Gradual increase is expected.
Snow Scale: 31% of groves infested; 23% economic. Population is higher than in any prior
month. Slight increase is expected.
Whitefly: Adults and eggs are more numerous than normal for March. Rapid increase of these
forms is expected until mid-April.
Aphids: 10% of groves infested; none economic. Although population is near normal and cur-
rently low, rapid increase will occur. Important infestations may be expected through April in
groves of Temple, Honey Tangerine and in other susceptible varieties.
