Fruit Bins Washed with Steinernema carpocapsae (Rhabditida: Steinernematidae) to Control Cydia pomonella (Lepidoptera: Tortricidae)

摘要: A bin washing apparatus (drencher) was used to treat late-instar codling moth, Cydia pomonella Linnaeus-infested wooden fruit bins with the entomopathogenic nematode Steinernema carpocapsae . Sentinel moth larvae were placed in strips of wood, made from dismantled bins, that subsequently screwed into corners real before treatment. Pre-soaking water prior treatment and covering a plastic tarp post-treatment, maintain high humidity, significantly increased sentinel mortality. Treatment for 1 min 50 S. infective juveniles mL -1 resulted more than 80% mortality over 6 h which nematodes continuously pumped through drencher. The temperature washer h 15°C chlorine city too low harm nematodes. key disadvantage labour involved. It may be possible reduce post-treatment holding time i...
