If the maximum of 50 flower clusters are sampled and no decision is indicated, the grower should sample again in 1 or 2 days. This method allows scouts to spend less time monitoring in fields where popu-lations are very low, or very high. More time is spent sampling fields where TPB populations are close to the threshold. Controlling weeds in and around the planting may reduce populations of this insect, but insecticide sprays may be necessary. Five to ten leaves should be sampled at each location for a total of 60 leaves.
Natural predators exist which feed on two-spotted spider mites.
It is equally small but lacks the two spots on its back, is teardrop shaped, shiny, and pale yellow in color. When sampling a field, presence of predators as well as TSSM should be noted. Relying solely on the release of commercially reared mites is not recommended since natural populations of N. fallacis are pervasive. Please note that oil-incompatible pesticides should not be applied prior to the oil spray. The weevils will sometimes crawl in among the unopened buds for shelter.
