CONTROL OF THE OAK-LEAF SHREDDER, CROESIA SEMIPURPURANA (KEARFOTT) (LEPIDOPTERA: TORTRICIDAE), BY AERIAL APPLICATION OF DIFLUBENZURON
Keyword(s):
AbstractUnlike some tortricids that are refractory to diflubenzuron, the oak-leaf shredder, Croesia semipurpurana (Kearfott), is susceptible to this molt-inhibiting insect growth regulator. Aerial application of 140 g in 4.7 L/ha provides good control of this insect and affords foliage protection. The success of diflubenzuron was evaluated by sampling larvae and pupae. Monitoring male moths with pheromone traps provided corroborative evidence of a significant decrease in the post-treatment population. The successful assessment by pheromone monitoring here merits its consideration for other control operations in forestry.
