Asian bean thrips (ABT) populations were low this week across South Florida, according to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The largest population counts were reported in snap bean blooms in central Hendry County. Even then it did not surpass 0.5 ABT per bloom.
There was also only a few ABT on sticky traps, and counts were in the single digits.
ABT thresholds are still being developed and may vary between regions and planting cycle. UF/IFAS does not recommend insecticide applications until populations reach 1.0 ABT per bloom.
