Abstract : The parasitic wasp Trichogramma nubilale (Hymenoptera: Trichogrammatidae) is one of the most suitable parasitoids for controlling Asian corn borer, Ostrinia furnacalis (Lepidoptera: Crambidae). Although extensive toxicological tests have been carried out to elucidate the toxicities of insecticides to trichogrammatids, the acute toxicity risks of commonly used insecticides to T. nubilale are not well known. Among the 7 classes of tested chemicals, organophosphates and carbamates had the highest intrinsic toxicity to the parasitoid with LC50 values ranging from 0.081 (0.062–0.12) to 2.10 (1.23–3.47) and from 0.12 (0.11–0.14) to 0.95 (0.87–1.05) mg a.i. per liter, respectively. The phenylpyrazoles (with the exception of butene-fipronil), avermectins, neonicotinoids and pyrethroids induced intermediate toxicity responses with LC50 values ranging from 0.29 to 4.67, 2.36 to 11.27, 1.86 to 311.9, and 10.98–150.3 mg a.i. per liter, respectively. In contrast, insect growth regulators (IGRs) exhibited the least toxicity to the parasitoid with LC50 values ranging from 3452 (3114–3877) to 10,168 (8848–12,027) mg a.i. per liter. A risk quotient analysis indicated that neonicotinoids, avermectins, pyrethroids, IGRs and phenylpyrazoles (with the exception of butene-fipronil) were safe, but organophosphates and carbamates were slightly to moderately toxic or highly toxic to T. nubilale. This study provided informative data for implementing both biological and chemical control strategies in integrated pest management (IPM) of corn lepidopterans.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae. Likewise, monoterpene hydrocarbons showed the higher toxicity against the adults than oxygenated monoterpenes. Limonene, α-pinene and β-pinene caused 100% mortality against the adults at two doses after 24 h of exposure. Among the tested oxygenated monoterpenes, 1,8-cineole, fenchone and menthone were much more effective against the adults. The present results indicated that 1,8-cineole, fenchone, β-pinene and γ-terpinene can be used as potential control agents against both the larvae and adults of Colorado potato beetle.

Abstract : In the present study, 30 pure monoterpenes were tested for their toxicity against first, second and third instars larvae and adults of Colorado potato beetle (Leptinotarsa decemlineata Say). The majority of tested compounds were found to be toxic to the larvae and the adults, however variable degree of toxicity with a range of 20-100% mortality. In general, monoterpene hydrocarbons exhibited high toxicity as compared with oxygenated monoterpenes. Among the tested monoterpene hydrocarbons, β-pinene, γ-terpinene, 3-carene as well as myrcene showed strong toxicity against all instars larvae. On the other hand, 1,8-cineole, fenchone, linalool and terpinen-4-ol were more toxic against the larvae as compared with the toxicities of other oxygenated monoterpenes. Borneol, fenchol, geranyl acetate, menthol, nerol acetate and α-terpineol showed weak toxicity against the larvae, whereas no significant toxicity was observed for isomenthol against the larvae. Some tested compounds showed different toxicities against both adults and larvae. For instance, menthone was more toxic against the adults than the larvae.

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.
