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.

Title : Cross-resistance patterns and fitness in fufenozide-resistant diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae).

Abstract : BACKGROUND: Fufenozide is a novel non-steroidal ecdysone agonist with good efficacy against diamondback moth (DBM), Plutella xylostella (Lepidoptera: Plutellidae). At present, it is widely applied for the control of a range of lepidopterous pests in China. This study compared the activities of fufenozide and 12 other insecticides against unselected and fufenozide-selected strains of DBM to examine potential patterns of cross-resistance. The relative fitness of the fufenozide-selected strain was assessed to provide information pertinent to insecticide resistance management. RESULTS: Compared with the susceptible strain (JSS), the fufenozide-resistant strain (JSR) showed high cross-resistance to dibenzoylhydrazines and benzoylphenylureas, low cross-resistance to abamectin and no cross-resistance to organophosphates, carbamates and pyrethroids. JSR had a lower reproductive ability and a relative fitness of 0.5 compared with JSS. CONCLUSION: P. xylostella has the potential to develop resistance to fufenozide, albeit at the expense of fitness. Cross-resistance between the same and other classes of insecticides is of concern, and should be a key consideration when implementing fufenozide-based control strategies for this species.
