Abstract : Neonicotinoids not only control insect pests but also sometimes independently alter plant growth and response to stress. We find that imidacloprid, thiacloprid, acetamiprid, thiamethoxam, and clothianidin but not nitenpyram and dinotefuran induce foliar lesions and peroxidative damage in soybean ( Glycine max ) seedlings assayed with the 3,3'-diaminobenzidine stain. The chloropyridinyl-carboxylic acid (COOH) but not the -carboxaldehyde (CHO) metabolites induce peroxidative damage but in a different pattern. Surprisingly, the chlorothiazolyl -CHO and -COOH metabolites induce chlorosis but no clear superimposable peroxidative damage or cell death. Four metallo-oxidases known to modulate reactive oxygen species were not sensitive in vitro to the parent neonicotinoid itself but were to several CHO and COOH metabolites and related compounds, with a sensitivity order of CHO > COOH and tyrosinase > xanthine oxidase and aldehyde oxidase > catalase. Although metallo-oxidase inhibition does not correlate overall with lesion formation, it may play an as yet unknown role in plant response to neonicotinoids.

Title : Responses of the cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae), to seed treatments of canola (Brassica napus L.) with the neonicotinoid compounds clothianidin and imidacloprid.

Abstract : BACKGROUND: The cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham), is a major pest in the production of canola (Brassica napus L.) in North America and Europe, and effective population control is often essential for economical crop production. In North America, neonicotinoid insecticides have been used for several years in canola as seed treatments for reducing herbivory by flea beetles. The neonicotinoids clothianidin and imidacloprid were investigated to determine their effects on preimaginal development and on emergence of new-generation adults of C. obstrictus in comparison with effects of lindane, a chlorinated hydrocarbon seed treatment. RESULTS: Mean numbers of second- and third-instar larvae were significantly higher in plants seed-treated with lindane than in plants treated with the neonicotinoid compounds, even though weevil oviposition was similar for all treatments. Emergence of new-generation adults was reduced by 52 and 39% for plants seed-treated with clothianidin and imidacloprid, respectively, compared with emergence from plants treated with lindane. CONCLUSION: Seed treatment with both clothianidin and imidacloprid produced systemic insecticidal effects on larvae of C. obstrictus, with clothianidin slightly more effective than imidacloprid. Use of clothianidin or imidacloprid as seed treatments can comprise an important component in the integrated management of cabbage seedpod weevil in canola.

Abstract : BACKGROUND: The cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham), is a major pest in the production of canola (Brassica napus L.) in North America and Europe, and effective population control is often essential for economical crop production. In North America, neonicotinoid insecticides have been used for several years in canola as seed treatments for reducing herbivory by flea beetles. The neonicotinoids clothianidin and imidacloprid were investigated to determine their effects on preimaginal development and on emergence of new-generation adults of C. obstrictus in comparison with effects of lindane, a chlorinated hydrocarbon seed treatment. RESULTS: Mean numbers of second- and third-instar larvae were significantly higher in plants seed-treated with lindane than in plants treated with the neonicotinoid compounds, even though weevil oviposition was similar for all treatments. Emergence of new-generation adults was reduced by 52 and 39% for plants seed-treated with clothianidin and imidacloprid, respectively, compared with emergence from plants treated with lindane. CONCLUSION: Seed treatment with both clothianidin and imidacloprid produced systemic insecticidal effects on larvae of C. obstrictus, with clothianidin slightly more effective than imidacloprid. Use of clothianidin or imidacloprid as seed treatments can comprise an important component in the integrated management of cabbage seedpod weevil in canola.

Title : Investigating the mode of action of sulfoxaflor: a fourth-generation neonicotinoid.

Abstract : The precise mode of action of sulfoxaflor, a new nicotinic acetylcholine receptor-modulating insecticide, is unclear. A detailed understanding of the mode of action, especially in relation to the neonicotinoids, is essential for recommending effective pest management practices.Radiolabel binding experiments using a tritiated analogue of sulfoxaflor ([(3) H]-methyl-SFX) performed on membranes from Myzus persicae demonstrate that sulfoxaflor interacts specifically with the high-affinity imidacloprid binding site present in a subpopulation of the total nAChR pool. In competition studies, imidacloprid-like neonicotinoids displace [(3) H]-methyl-SFX at pM concentrations. The effects of sulfoxaflor on the exposed aphid nervous system in situ are analogous to those of imidacloprid and nitenpyram, and finally the high-affinity sulfoxaflor binding site is absent in a Myzus persicae strain (clone FRC) possessing a single amino acid point mutation (R81T) in the β-nAChR, a region critical for neonicotinoid interaction.The nicotinic acetylcholine receptor pharmacological profile of sulfoxaflor in aphids is consistent with that of imidacloprid. Additionally, the insecticidal activity of sulfoxaflor and the current commercialised neonicotinoids is affected by the point mutation in FRC Myzus persicae. Therefore, it is suggested that sulfoxalfor be considered a neonicotinoid, and that this be taken into account when recommending insecticide rotation partnering for effective resistance management programmes.

Title : Variation in the laboratory susceptibility of turf-infesting white grubs (Coleoptera: Scarabaeidae) to biological, biorational and chemical control products.

Abstract : BACKGROUND: White grubs are the most widespread and damaging pests in turfgrass habitats of the northeast USA, and their management is highly dependent on chemical pesticides. Because this complex includes at least eight species, opportunities for pest management would be enhanced by understanding how susceptibility to control products varies across taxa. The objective of this laboratory study was to measure variation in the susceptibility of four species to 18 biological, biorational and chemical insecticides used as curative controls. RESULTS: Across species, the most efficacious biological and chemical insecticide alternatives were Steinernema scarabaei and chlorpyrifos respectively. For biorational and chemical insecticides, the European chafer [Amphimallon majale (Razoumowsky)] was the least susceptible species. For biologicals, the Japanese beetle (Popillia japonica Newman) was the least susceptible. Considering all control products, the oriental beetle [Anomala orientalis (Waterhouse)] was the most susceptible. CONCLUSION: The magnitude of variation in susceptibility supports the idea that a single product will not reliably suppress populations of all taxa, and highlights the need for pest management practitioners to identify white grub species before intervention. This differential susceptibility could have broader consequences for grub management if a numerically dominant target species is more completely suppressed than a co-occurring species.

Considering all control products, the oriental beetle [Anomala orientalis (Waterhouse)] was the most susceptible. CONCLUSION: The magnitude of variation in susceptibility supports the idea that a single product will not reliably suppress populations of all taxa, and highlights the need for pest management practitioners to identify white grub species before intervention. This differential susceptibility could have broader consequences for grub management if a numerically dominant target species is more completely suppressed than a co-occurring species.

Title : Variation in the laboratory susceptibility of turf-infesting white grubs (Coleoptera: Scarabaeidae) to biological, biorational and chemical control products.

Abstract : BACKGROUND: White grubs are the most widespread and damaging pests in turfgrass habitats of the northeast USA, and their management is highly dependent on chemical pesticides. Because this complex includes at least eight species, opportunities for pest management would be enhanced by understanding how susceptibility to control products varies across taxa. The objective of this laboratory study was to measure variation in the susceptibility of four species to 18 biological, biorational and chemical insecticides used as curative controls. RESULTS: Across species, the most efficacious biological and chemical insecticide alternatives were Steinernema scarabaei and chlorpyrifos respectively. For biorational and chemical insecticides, the European chafer [Amphimallon majale (Razoumowsky)] was the least susceptible species. For biologicals, the Japanese beetle (Popillia japonica Newman) was the least susceptible. Considering all control products, the oriental beetle [Anomala orientalis (Waterhouse)] was the most susceptible. CONCLUSION: The magnitude of variation in susceptibility supports the idea that a single product will not reliably suppress populations of all taxa, and highlights the need for pest management practitioners to identify white grub species before intervention. This differential susceptibility could have broader consequences for grub management if a numerically dominant target species is more completely suppressed than a co-occurring species.
