研究问题
However, these insecticides often exhibit high toxicity toward beneficial arthropods, including parasitoids and predators [].；However, its effectiveness against R. pedestris has not yet been systematically evaluated.；In contrast, information regarding its sublethal effects on R. pedestris remains limited.
方法
The assay procedure has been described in a prior publication [].；To minimize positional bias, the two odor sources were switched after every five trials, and a new Y-tube apparatus was used after every 10 individuals.；Each nymph was tested only once, and a total of 100 individuals were evaluated per treatment.；Based on the bioassay results, LC10 and LC30 values at 72 h were selected to assess sublethal effects, with 0.1% Tween-80 in water representing the control.
核心结论
Treating soybean seedlings with TFM elicited a concentration-dependent behavioral response in third-instar nymphs, indicating clear repellency at higher doses.；Compared with the control, nymphs showed significant avoidance of seedlings treated at LC50 (χ2 = 6.37, df = 1, P = 0.012) and LC70 concentrations (χ2 = 10.71, df = 1, P = 0.001).；In contrast, no statistically significant behavioral differences were observed at either LC10 (χ2 = 0.01, df = 1, P = 0.92) or LC30 (χ2 = 2.65, df = 1, P = 0.10) concentrations (). ‖ 结论：These results demonstrate that TFM suppresses R. pedestris not only through acute toxicity and behavioral deterrence but also through sublethal effects that persist into the unexposed F1 generation, supporting its use as a component of IPM programs for this pest.
局限
Future studies integrating electropenetrography to quantify feeding behavior with transcriptomic analyses of stress-responsive pathways would help elucidate the causal links between TFM exposure and the observed developmental costs.；Because the insects assayed had survived exposure to LC10 and LC30, this induction also represents a metabolic cost in survivors, and its possible contribution to reduced susceptibility under repeated field application warrants monitoring.；To facilitate its field adoption, future research should prioritize validating these laboratory-derived population parameters under field conditions and exploring the molecular mechanisms (e.g., vitellogenin regulation or epige
