“…Longer‐term D. suzukii data generated in this study (not shown), resulted in mortality levels similar to those found in studies conducted previously. Generally, in earlier studies, adult mortality rates for malathion, spinetoram, zeta‐cypermethrin, and methomyl were similar to those found in the current study and these insecticides are effective at managing this insect . The current study, however, provides more detailed insight into rapid toxic effects of different insecticides.…”

BACKGROUND Insecticide applications in blueberry production systems play a crucial role in the control of Drosophila suzukii populations. Here, quantitative spray deposition patterns were obtained under replicated field experiments in blueberry during two field seasons with three sprayers, i.e. cannon, electrostatic, and air‐blast. Seven insecticides were tested (at 6 hours using a Potter spray tower) to determine the mortality data for adult D. suzukii. Spray deposition and mortality data for adult D. suzukii were used to create model simulations for insect populations. Model simulations included field deposition rates of sprayers and insecticide mortality as factors. Simulations were applied in different combinations with five applications over a 6‐week period. RESULTS Relative deposition rates for the cannon sprayer were elevated in the upper zones of the canopy, whereas for the air‐blast sprayer, deposition was greater in the bottom zones. Electrostatic spray deposition was relatively uniform within the six canopy zones. Clear trends in D. suzukii laboratory mortality were found with lowest to highest mortality recorded for phosmet, spinetoram, spinosad, malathion, cyantraniliprole, zeta‐cypermethrin, and methomyl respectively. Maximum D. suzukii population impacts, as shown by model outputs, were observed with air‐blast sprayers together with zeta‐cypermethrin. CONCLUSION The electrostatic sprayer had the least variable canopy deposition among the three types of spray equipment, and the air‐blast sprayer had the highest overall deposition rates. This study provides new hypotheses that can be used for field verification with these spray technologies and insecticides as key factors. © 2019 Society of Chemical Industry

“…Insecticides with some effectiveness against D. suzukii include organophosphates, pyrethrins and spinosyns; at present, an effective insecticide class for suppression of D. suzukii is perceived to be spinosyns (spinosad and spinetoram) while the neonicotinoid insecticides tend to be less effective against adults [26,27,28,29]. The narrow range of options, particularly in organic production, requires that insecticide treatments are carefully optimized in order to prolong their effectiveness and counter the development of resistance [29,30]. Frequent, prophylactic, and sometimes superfluous insecticide applications add to the growers’ private costs and also have negative external effects due to detrimental impacts on the environment and human health [31].…”

First detected in Switzerland in 2011, the invasive Drosophila suzukii, spotted wing drosophila, has caused recurring costs for growers of berries and fruit. Recommended management approaches rely on a set of methods, tailored to suit crop requirements under the prevailing local conditions. Control of D. suzukii represents a substantial economic burden for growers, in terms of material, equipment, new infrastructure and extra labour. However, those growers who invest wisely to deliver unblemished produce are rewarded with high payoffs. We present insights from a growers’ survey conducted in 2015 and 2016 to gauge the impact of the introduction and establishment of D. suzukii on Swiss sweet cherry production. The surveyed growers (111 in 2015 and 298 in 2016) observed the recommended surveillance, sanitation and control measures. The use of insecticides (78% and 79% of respondents in 2015 and 2016, respectively) and the harvest of all fruits (93% and 59% of respondents in 2015 and 2016, respectively) were the most widespread methods used to reduce damage. Nearly one-third of the respondents set up enclosure nets. Our economic evaluation of different scenarios provides a quantitative indication of the potentially incurred costs. We argue for enhanced stakeholder involvement to raise the acceptance of integrated pest management practices, and to inform research and outreach by providing insights into the motivations and barriers to adoption.

In just a few years, the Asian fly Drosophila suzukii has invaded several continents and has become a very serious pest of many fruit crops worldwide. Current control methods rely on chemical insecticides or expensive and labour-intensive cultural practices. Classical biological control through the introduction of Asian parasitoids that have co-evolved with the pest may provide a sustainable solution on condition that they are sufficiently specific to avoid non-target effects on local biodiversity. Here, we present the first study on the development of three larval parasitoids from China and Japan, the Braconidae Asobara japonica and the Figitidae Leptopilina japonica and Ganaspis sp., on D. suzukii. The Asian parasitoids were compared with Leptopilina heterotoma, a common parasitoid of several Drosophilidae worldwide. The three Asian species were successfully reared on D. suzukii larvae in both, blueberry and artificial diet, in contrast to L. heterotoma whose eggs and larvae were encapsulated by the host larvae. All parasitoids were able to oviposit one day after emergence.Asobara japonica laid as many eggs in larvae feeding in blueberry as in artificial diet, whereas L. heterotoma oviposited more in larvae on the artificial diet and the Asian Figitidae oviposited more in larvae feeding on blueberry. Ganaspis sp. laid very few eggs in larvae in the artificial diet, suggesting that it may be specialized in Drosophila species living in fresh fruits. These data will be used for the development of a host range testing to assess the suitability of Asian parasitoids as biological control agents in invaded regions. K E Y W O R D SAsobara, Ganaspis, invasive species, Leptopilina, pre-oviposition period, spotted wing drosophila short development time of the fly, they have to be applied regularly and can cause severe environmental and health concerns (Bruck et al., 2011;Cuthbertson, Collins, Blackburn, Audsley, & Bell, 2014;Sampson, Werle, Stringer, & Adamczyk, 2017;Smirle, Zurowski, Ayyanath, Scott, & MacKenzie, 2017;Van Timmeren & Isaacs, 2013).Cultural management such as the use of insect-proof nets, mass trapping and removal or solarization of infested fruits are also used, but these strategies are expensive and labour-intensive and have to be adjusted to each type of fruit crop or cultivation system (Haye et al., 2016). New control techniques focusing on long-term management are therefore urgently needed. As wild host plants constitute a large reservoir of individuals that can potentially reinvade field crops, controlling the pest at a landscape level is essential.A number of natural enemies are known to have an impact on the dynamics and regulation of Drosophila spp. and may provide an area-wide control of fly populations (Carton, Bouletreau, Lenteren, & Alphen, 1986;Fleury, Gibert, Ris, & Allemand, 2009).Two generalist pupal parasitoids, Trichopria drosophilae Perkins (Hymenoptera, Diapriidae) and Pachycrepoideus vindemmiae (Rondani) (Hymenoptera, Pteromalidae), are found attacking D. suzukii worldwide ...
