“…suzukii was the most pronounced, and its horizontal transfer between sexes and its ability to achieve mortality rates exceeding 95% even at 20°C makes this strain a promising candidate as part of a control strategy. However, these studies confirm that the success of a biocontrol is likely to depend on the species or even strain of the biocontrol agent, as previously reported (Cossentine, Robertson, & Buitenhuis, ; Cossentine, Robertson, & Xu, ; Woltz et al., ).…”

The spotted-wing drosophila or cherry vinegar fly (Drosophila suzukii) is native to Asia but has invaded other continents since 2008 and has spread throughout Europe. The females have a serrated ovipositor allowing them to penetrate the skins of intact ripening fruits to deposit their eggs, and the developing larvae rapidly destroy the fruits close to harvest. Drosophila suzukii has a rapid life cycle and the larvae develop well beneath the fruit surface. This means that the use of pesticides is problematic and often not effective, first due to their restricted use close to harvest to protect consumers, and second because the larvae are deep enough inside the fruit to avoid contact.There are currently no effective and environmentally sustainable pest control methods for this species, resulting in extensive damage to fruit crops. Here, we review the current status of D. suzukii as a fruit crop pest and discuss the feasibility of current pesticide-free control methods. We also consider the potential of new technologies as a basis for the urgently needed specific and long-term control of this species.

“…10,14,26 Reductions in the reproductive capacity of insects infected with Metarhizium isolates have been demonstrated in multiple insect species. [27][28][29][30] However, there is limited research on the reproductive effects of M. anisopliae infection in M. domestica. 31,32 Unlike chemical insecticides, entomopathogenic fungi are relatively slow-killing, which could potentially allow insect reproduction to occur prior to death.…”

BACKGROUND RESULTSMetarhizium anisopliae was transmitted between adult M. domestica flies with 91.67% -100% mortality resulting across the three ratios of infected: non-infected flies tested (1:2, 1:5, 1:10). The mean lethal time (LT50) for female recipients mixed with infected male donor flies at the three ratios were 3.95, 4.79 and 5.65 days, respectively, whereas for male recipients mixed with infected female donors at the same ratios the LT50 were 4.98, 5.98 and 7.44 days, respectively. Infection with M.anisopliae significantly reduced the reproductive capacity of female flies during the first four days of infection with 25% less eggs oviposited by infected flies than those that were uninfected. CONCLUSIONAutodissemination among house flies and reduction in oviposition in the early stages of infection could contribute significantly to the effectiveness of M. anisopliae used in biocontrol programs.

Drosophila suzukii is a major pest of soft‐skinned fruits, and insecticides are often used to prevent fruit damage caused by oviposition. As D. suzukii produces many generations per year, repeated insecticide applications are required. Furthermore, D. suzukii attacks ripening and ripe fruits shortly before harvest. Therefore, the use of synthetic insecticides is limited by long pre‐harvest intervals and maximum residue limits. To be able to offer producers immediate and sustainable solutions, we tested 25 natural crop protection products with three different application methods in a laboratory screening. We show that application method is an important factor for the efficacy of the tested products. Of six natural insecticides, only Spinosad was toxic for D. suzukii and reduced the oviposition on treated blueberries. The tested oil products had no control effect and products based on different entomopathogenic fungi and Bacillus thuringiensis rather enhanced oviposition. Mineral products (Kaolin, CaCO3, Ca(OH)2 and clinoptilolith) applied as spray solutions were not toxic, but significantly reduced oviposition on blueberries. We provide the first study in which different application methods have been used to compare numerous, commercially available, natural crop protection products with different modes of action against adult D. suzukii. Our findings provide consultants and producers with important insights for the development of sustainable pest control strategies against D. suzukii.
