“…A comparison of individual data sets obtained externally revealed a slightly higher variation at all discriminating rates tested, most likely due to the fact that more than 100 persons conducted the bioassays (Figure 1). The pyrethroid resistance mechanisms yet described include oxidative degradation of pyrethroids by elevated levels of cytochrome P450 monooxygenases and target-site resistance due to an L1014F mutation in the voltage-gated sodium channel (Zimmer & Nauen, 2011b;Nauen et al, 2012). Strain 91-11 collected in Ukraine is susceptible, whereas all others are resistant to pyrethroids Table 2 for corresponding adult mortality).…”

Pollen beetle, Meligethes aeneus (Fabricius) (Coleoptera: Nitidulidae), and cabbage seed weevil, Ceutorhynchus assimilis (Paykull) (Coleoptera: Curculionidae), are important pests in the production of European winter oilseed rape, Brassica napus L. (Brassicaceae), which is grown on several million hectares in Europe. Insecticide treatments are common to control both pests once they exceed economic damage thresholds; however, not many chemical classes are available for their control in European oilseed rape. Particularly pollen beetles recently developed high levels of pyrethroid resistance impairing field control at recommended rates in many countries, whereas no resistance is yet reported to another important insecticide, thiacloprid. The major objective of this study was to investigate the spatio-temporal susceptibility status of pollen beetle against the recently introduced insecticide thiacloprid. From 2009 to 2012 more than 630 populations of pollen beetle collected in 13 countries were monitored for resistance to thiacloprid by using an adult vial test. No shifting to lower susceptibility of pollen beetle to thiacloprid has been observed between 2009 and 2012. Furthermore, we were able to show that pollen beetle larvae are extremely susceptible to thiacloprid, whereas within strains larvae are significantly more resistant than adults to pyrethroids such as lambda-cyhalothrin. Dose-response data for thiacloprid against cabbage seed weevil populations collected in 2011 in Germany, Sweden, and Ukraine showed a 10-fold higher intrinsic sensitivity compared to pollen beetle, and showed only a low variation in response. In addition, we also tested 17 cabbage seed weevil populations collected in five countries against lambda-cyhalothrin with low variation in response (three-fold), suggesting full baseline susceptibility and no resistance to pyrethroids. The implications of the data presented for resistance management in coleopteran pests in winter oilseed rape are discussed.

“…The occurrence of a target‐site mechanism caused by a modification of the pollen beetle para ‐type voltage‐gated sodium channel gene was reported in samples from Denmark and Sweden. However, the mutation in the sodium channel gene was absent in the majority of tested populations . In our study, target‐site resistance was tested using a polymerase chain reaction (PCR) assay in samples of highly resistant pollen beetle populations based on the results of the bioassay.…”

“…They cause feeding damage to flower buds, resulting in bud abscission and loss of yield . Improving the sustainability of pollen beetle management has become an increasingly urgent issue in the light of evidence for overuse of insecticides in their control and the threat posed by widespread insecticide resistance . There is a need for detailed studies on pollen beetle biology and behaviour to underpin the development of robust and practical decision support tools to improve targeting of control methods and stewardship of insecticides…”

BACKGROUNDPollen beetle (Meligethes aeneus F.) management in oilseed rape (Brassica napus L.) has become an urgent issue in the light of insecticide resistance. Risk prediction advice has relied upon flight temperature thresholds, while risk assessment uses simple economic thresholds. However, there is variation in the reported temperature of migration, and economic thresholds vary widely across Europe, probably owing to climatic factors interacting with beetle activity and plant compensation for damage. The effect of temperature on flight, feeding and oviposition activity of M. aeneus was examined in controlled conditions.RESULTSEscape from a release vial was taken as evidence of flight and was supported by video observations. The propensity to fly followed a sigmoid temperature–response curve between 6 and 23 °C; the 10, 25 and 50% flight temperature thresholds were 12.0–12.5 °C, 13.6–14.2 °C and 15.5–16.2 °C, respectively. Thresholds were slightly higher in the second of two flight bioassays, suggesting an effect of beetle age. Strong positive relationships were found between temperature (6–20 °C) and the rates of feeding and oviposition on flower buds of oilseed rape.CONCLUSIONThese temperature relationships could be used to improve M. aeneus migration risk assessment, refine weather-based decision support systems and modulate damage thresholds according to rates of bud damage. © 2014 Society of Chemical Industry
