“…For example, recent trials conducted in highbush blueberries in Michigan showed that the duration of fruit protection is variable among insecticides, and that efficacy declines rapidly if the residues are washed off by rain (Van Timmeren and Isaacs 2014). Research into the mechanisms by which effective insecticides are achieving fruit protection have revealed that eggs and larvae can be controlled after penetration of the fruit, highlighting that adult fly control is likely only one component of the mechanisms by which crop protection is achieved (Wise et al 2014).…”

The Asian vinegar fly Drosophila suzukii (spotted wing Drosophila [SWD]) has emerged as a major invasive insect pest of small and stone fruits in both the Americas and Europe since the late 2000s. While research efforts have rapidly progressed in Asia, North America, and Europe over the past 5 years, important new insights may be gained in comparing and contrasting findings across the regions affected by SWD. In this review, we explore common themes in the invasion biology of SWD by examining (1) its biology and current pest status in endemic and recently invaded regions; (2) current efforts and future research needs for the development of predictive models for its geographic expansion; and (3) prospects for both natural and classical (=importation) biological control of SWD in invaded habitats, with emphasis on the role of hymenopteran parasitoids. We conclude that particularly fruitful areas of research should include fundamental studies of its overwintering, host-use, and dispersal capabilities; as well as applied studies of alternative, cost-effective management techniques to complement insecticide use within the integrated pest management framework. Finally, we emphasize that outreach efforts are critical to effective SWD management by highlighting successful Communicated by M. Traugott.

“…As an example, adult mortality differed between laboratory assays using direct application, from 10% in flies treated with novaluron (group; benzoylureas, inhibitors of chitin biosynthesis) to 100% when treated with zeta-cypermethrin (group; pyrethroid, targets sodium channel modulator), spinosad and spinetoram (group; spinosyn, targets nicotinic acetylcholine receptor) (Bruck et al, 2011, IRAC, 2018. Protection against oviposition ranges from 1 to >14 days, depending on the product used and cropping system (Fountain et al, 2016) and insecticides have also reduced larval and pupal development when applied up to 5 days post-egg laying (Wise et al, 2014).…”

Implications of sub-lethal rates of insecticides and daily time of application on Drosophila suzukii lifecycle

The circadian clock is responsible for time keeping within an organism and influences not only behavioural patterns, but also physiological rhythms including toxin susceptibility. Drosophila suzukii Matsumura is a global horticultural pest, and identifying rhythms in insecticide susceptibility could contribute to improving integrated pest management practices. To determine whether time of application influences mortality, LC50 rates of cyantraniliprole, lambda-cyhalothrin, pyrethrum and spinosad were applied to groups of adult D. suzukii at two different times of day. Insecticides were directly applied using a benchtop sprayer. We found no influence of time on mortality or oviposition for any of the four insecticides applied. However, several discoveries were made regarding the impact of sub-lethal and lethal rates on D. suzukii mortality, oviposition and offspring survival over time. In most cases, all surviving females recovered from insecticide rates, and laid the same number of eggs as females treated with the water control. Seven days after application, females that were treated with the field rate of spinosad laid the same number of eggs as the control. The lowest rate of cyantraniliprole resulted in more eggs being laid, initially, with no negative impact on survival of eggs through to adult emergence. However, there were transgenerational impacts of egg to adult survival when parents were treated with sub-lethal rates of spinosad and lambda-cyhalothrin. Although no impact of daily phase of application was detected within this assay, the information surrounding how D. suzukii interacts with lethal and sub-lethal rates of insecticides is of great importance, especially for the resistance management of D. suzukii.

“…Management strategies for D. suzukii include chemical (Beers et al 2011 ; Bruck et al 2011 ; Van Timmeren and Isaacs 2013 ; Wise et al 2015 ), biological (Rossi Stacconi et al 2013 , 2015 ; Miller et al 2015 ), and cultural (Lee et al 2015b ; Tochen et al 2015 ) controls. Additional control strategies may include genetic techniques such as RNAi biopesticides (Murphy et al 2016 ).…”

Drosophila suzukii population response to environment and management strategies

Drosophila suzukii causes economic damage to berry and stone fruit worldwide. Laboratory-generated datasets were standardized and combined on the basis of degree days (DD), using Gompertz and Cauchy curves for survival and reproduction. Eggs transitioned to larvae at 20.3 DD; larvae to pupae at 118.1 DD; and pupae to adults at 200 DD. All adults are expected to have died at 610 DD. Oviposition initiates at 210 DD and gradually increases to a maximum of 15 eggs per DD at 410 DD and subsequently decreases to zero at 610 DD. These data were used as the basis for a DD cohort-level population model. Laboratory survival under extreme temperatures when DD did not accumulate was described by a Gompertz curve based on calendar days. We determined that the initiation of the reproductive period of late dormant field-collected female D. suzukii ranged from 50 to 800 DD from January 1. This suggests that D. suzukii females can reproduce early in the season and are probably limited by availability of early host plants. Finally, we used the DD population model to examine hypothetical stage-specific mortality effects of IPM practices from insecticides and parasitoids at the field level. We found that adulticides applied during the early season will result in the largest comparative population decrease. It is clear from model outputs that parasitism levels comparable to those found in field studies may have a limited effect on population growth. Novel parasitoid guilds could therefore be improved and would be valuable for IPM of D. suzukii.
