Taeniothrips orionis oviposition and feeding injury on cherries

R. D. McMullin


Oviposition by overwintered <i>Taeniothrips orionis</i> Treherne in the ovaries of cherry flowers and immature fruits during early May caused injury which resulted in dimple-like depressions on the mature fruits. The damage was widespread in the Okanagan Valley in 1971. First brood adults oviposited in cherry fruits during late June and early July but the injury caused at this time was less pronounced. Feeding injury by larvae caused russeting on fruits and chlorotic areas paralleling secondary veins on leaves.
