“…Any successful resistance‐monitoring program developed for D. suzukii will need to be easy and efficient to use in order to be adapted to multiple monitoring situations. Resistance monitoring should ideally be deployed broadly to detect resistance in populations before it becomes widespread . This can only be accomplished through the investment of significant monetary resources, or by using a less expensive method for quick initial screening of populations.…”

“…The use of diagnostic doses is common in resistance‐monitoring programs and there are established methods for selecting these levels . Testing one or two diagnostic concentrations allows for quicker initial testing of multiple populations, and then suspect populations can subsequently be tested in more detail to determine whether there is resistance in a population.…”

“…Resistance‐monitoring programs are often challenging to implement due to the time and money required. Using a diagnostic dose approach can provide rapid and reliable monitoring to support widespread implementation of resistance monitoring . For example, Stanley describes a resistance‐monitoring program that used a two‐dose diagnostic system to monitor for cypermethrin resistance in Helicoverpa armigera Hubner in West Africa.…”

“…Vials were treated at a central location in France, shipped with a pictorial instruction card to investigators in Africa, and data sheets were subsequently returned for data analysis. This allowed for extensive sampling of H. armigera populations in rural areas in a cost‐effective and efficient manner, and identified some areas with lower efficacy …”

BACKGROUND: Spotted wing Drosophila is an invasive pest of fruit crops in most production regions globally, and insecticides are commonly used for its control. The biology of this pest combined with repeated pesticide exposure increases the risk of resistance to insecticides. We tested malathion, methomyl, spinetoram, spinosad, and zeta-cypermethrin against multiple colonies from each state using a contact bioassay method to determine diagnostic doses for assessment of insecticide susceptibility in this species. These were used to test populations collected in Michigan and Georgia, USA. RESULTS: Concentrations required to reach 50% (LC 50 ) and 90% mortality (LC 90 ) were calculated for the tested populations, and male mortality consistently occurred at lower concentrations than female mortality. Fly mortality did not vary significantly among populations collected from unmanaged, organic, and conventional fields. Similar results were found using the diagnostic concentrations applied to glass jars. CONCLUSIONS: Using this method, samples of D. suzukii that are freshly caught or reared from fruit can be tested within 1 day for their mortality in response to discriminating doses of five key insecticides. This method can be used to inform proactive resistance management strategies within integrated pest management programs.

Drosophila suzukii (Matsumura) has spread rapidly, challenging berry and cherry crop production due to its ability to lay eggs into ripening fruit. To prevent infestation by this pest, insecticides are applied during fruit ripening and harvest. We field-tested the Rapid Assessment Protocol for IDentification of resistance in D. suzukii (RAPID) on seventy-eight populations collected across eight U.S. states in 2017 and 2018. Exposure to LC50 rates of malathion, methomyl, spinetoram, spinosad, and zeta-cypermethrin led to average female fly mortality of 25.0% in 2017, and after adjusting concentrations the average was 39.9% in 2018. Using LC99 × 2 discriminating concentrations in 2017 and LC90 × 8 rates in 2018, average female mortalities were 93.3% and 98.5%, respectively, indicating high overall susceptibility. However, using these high concentrations we found 32.0% of assays with survival of some female flies in 2017 and 27.8% in 2018. The adjustment in discriminating dose from 2017 to 2018 also reduced the proportion of assays with <90% survival from 17.6 to 2.9%. Populations with low mortality when exposed to spinosad were identified using this assay, triggering more detailed follow-up bioassays that identified resistant populations collected in California coastal region berry crops. Widespread evaluations of this method and subsequent validation in California, Michigan, and Georgia in 2019–2021 show that it provides a quick and low-cost method to identify populations of D. suzukii that warrant more detailed testing. Our results also provide evidence that important insecticide classes remain effective in most U.S. regions of fruit production.
