20 mites per leaf later in the season. Predators play an important role in keeping twospotted spider mite populations in check. Subsequent innundative releases of predaceous mites may reduce twospotted mite infestations. Following releases of predator mites, it is important to monitor spider mites to determine if they are being maintained below economically injurious levels. Choose insecticides, miticides, and fungicides carefully to prevent killing the predators.
Strawberry cultivars vary in susceptibility to twospotted spider mite.
Vernalization directly promotes plant vigor. Supplemental cold storage can affect a plant's vernalization. Plants with low amounts of chilling will have low vigor and will often develop intolerable mite infestations.
