• Grape berry moth

(a) change in pest status

(b) trapping difficulties - surroundings, non-target species

(c) changes in chemical control - FQPA, new chemistry

(d) mating disruption - hand-placed dispensers (ropes), sprayable pheromone (MEC)

(e) climatic effects on population development and pest status
 

• winter mortality
• diapause maintenance & termination - first spring activity
• diapause induction - effect on final generation?
