title: Laboratory and field comparisons of insecticides to reduce infestation of Drosophila suzukii in berry crops.
abstract: BACKGROUND
  The spotted wing Drosophila, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is an invasive pest of small-fruit crops. Unlike most other Drosophila, this insect is able to oviposit into and damage ripe and ripening fruit, making it unmarketable. Because this is a new pest in the United States, it is necessary to identify registered insecticides to manage this insect effectively in conventional and organic production systems.
  
  
  RESULTS
  The present laboratory bioassays and field trials identified a number of insecticides representing various modes of action that are effective in controlling D. suzukii. Products that performed well in the laboratory bioassay also performed well in the field, indicating that screening of new chemistries in the laboratory is a worthy exercise. Field application of pyrethoids, organophosphates or spinosyns provided 5-14 days of residual control of D. suzukii. The efficacy of the neonicotinoids as adulticides was not satisfactory compared with the other contact-mode-of-action chemistries. Based on the zero tolerance by the small-fruit industry and the individual effects mentioned above, neonicotinoids are not currently recommended for D. suzukii management.
  
  
  CONCLUSIONS
  There are effective insecticides registered for controlling D. suzukii infestations in susceptible small-fruit crops.
