are pheromone traps applicable to forecast an insect pest phenology? a case study on codling moth

Codling Moth Areawide Integrated Pest Management

Gypsy moth (Lepidoptera: Lymantriidae) flight behavior and phenology based on field-deployed automated pheromone-baited traps.

Populations of the gypsy moth, Lymantria dispar (L.), are extensively monitored in the United States through the use of pheromone-baited traps. We report on use of automated pheromone-baited traps that use a recording sensor and data logger to record the unique date-time stamp of males as they enter the trap. We deployed a total of 352 automated traps under field conditions across several U.S. ...

Evaluation of Alternative Pheromone Dispensing Technologies for Codling Moth

Two new types of hand-applied pheromone dispensers, “meso-emitters”, were developed in collaboration with Suterra that increased the pheromone release rate per dispenser and decreased the number of dispensers per acre to only 12. Realized emission rates per dispenser only achieved 15-33% of the desired release rate. Further modifications are planned for 2007 to increase these release rates. In ...

Codling moth management and chemical ecology.

Lepidopteran insects use sex pheromones to communicate for mating. Olfactory communication and mate-finding can be prevented by permeating the atmosphere with synthetic pheromone. Pheromone-mediated mating disruption has become a commercially viable pest management technique and is used to control the codling moth, Cydia pomonella, a key insect pest of apple, on 160,000 ha worldwide. The codlin...

An Insecticide Further Enhances Experience-Dependent Increased Behavioural Responses to Sex Pheromone in a Pest Insect

Neonicotinoid insecticides are widely used to protect plants against pest insects, and insecticide residues remaining in the environment affect both target and non-target organisms. Whereas low doses of neonicotinoids have been shown to disturb the behaviour of pollinating insects, recent studies have revealed that a low dose of the neonicotinoid clothianidin can improve behavioural and neurona...

Automatic moth detection from trap images for pest management

Monitoring the number of insect pests is a crucial component in pheromone-based pest management systems. In this paper, we propose an automatic detection pipeline based on deep learning for identifying and counting pests in images taken inside field traps. Applied to a commercial codling moth dataset, our method shows promising performance both qualitatively and quantitatively. Compared to prev...
