据报道，一些亚致死剂量的杀虫剂可以刺激或降低昆虫的存活率和繁殖力。许多亚致死效应研究仅在一代人接触亚致死杀虫剂后进行，但关于长期接触亚致死杀虫剂对昆虫的亚致死效应的信息很少。在本研究中，研究了西方富兰氏杆菌对多杀菌素敏感株(Spin-S)和亚致死剂量多杀菌素处理株(Spin-Sub)暴露于相应的亚致死浓度多杀菌素后生物学特性的变化。结果表明，对于Spin-S菌株，多杀菌素的LC_(10)浓度对其亲本和后代的生物适合度影响不大。多杀菌素浓度延长了S品系的发育时间，降低了繁殖力，显著降低了自旋品系的内禀增长率、净繁殖率和有限增长率。然而，这些负面影响在后代(F1代)中并不像在父代中那么明显。对Spin-Sub品系而言，LC_(10)和LC_(25)浓度对Spin-Sub品系的发育和繁殖力影响不大，而LC_(10)和LC_(25)处理对Spin-Sub品系的影响差异不显著。与自旋-S品系相比，Spin-Sub品系表现出较短的发育时间、较大的内禀增长率和净繁殖率。这些发现结合我们之前的研究表明，与Spin-S品系相比，Spin-Sub品系的生物适合度提高了，并且该品系对亚致死剂量的Spinosad变得更适应。在亚致死剂量的长时间治疗后，生理和生化适应可能会导致这些变化。
Sublethal doses of some insecticides have been reported to either stimulate or reduce the survival and fecundity of insects. Many sublethal-effect studies have been conducted after exposure of only one generation to sublethal insecticides, and there is little information about the sublethal effects on insects after long-term exposure to sublethal insecticides. In this study, changes in biological characteristics were investigated in spinosad-susceptible (Spin-S) and sublethal-spinosad-treated (Spin-Sub) strains of Frankliniella occidentalis (Pergande) after exposure to their corresponding sublethal concentrations of spinosad. The results showed that for the Spin-S strain, the LC10 concentration of spinosad slightly affected the biotic fitness both in parents and offspring of F. occidentalis. The LC25 concentration of spinosad prolonged the development time, reduced the fecundity, and significantly reduced the intrinsic rate of increase, the net reproductive rate and the finite rate of increase in the Spin-S strain. However, the negative effects were not as pronounced in the offspring (F1 generation) as in the parent generation. For the Spin-Sub strain, the LC10 and LC25 concentrations of spinosad had little negative effect on the development and fecundity, and no significant difference was found between the effects of the LC10 and LC25 treatments on the Spin-Sub strain. The Spin-Sub strain exhibited a shorter developmental time, and larger intrinsic rates of increase and net reproductive rates, compared with the corresponding treatments of the Spin-S strain. These findings combined with our previous studies suggest that the biotic fitness increased in the Spin-Sub strain and the strain became more adaptable to sublethal doses of spinosad, compared with the Spin-S strain. Physiological and biochemical adaptation may contribute to these changes after long treatment times at sublethal doses.
