摘要
杀虫剂被广泛用于控制害虫和提高农业产量。滥用和持久性杀虫剂不仅导致害虫产生抗药性,还对非目标生物造成危害并污染环境。作为昆虫抗性控制计划的一部分,我们评估了 Spodoptera litura (Fabricius) 对 chlorantraniliprole (CTPR) 抗性的成本效益。我们从田地里采集了 S. litura 幼虫,并用氯虫苯甲酰胺处理了 15 代。与未选育的种群(Unsel-Lab)相比,氯虫苯甲酰胺选育的 S. litura 种群(CTPR-Sel)表现出 98.23 倍的抗性水平。研究结果表明,与氯酯抗性基因型相比,氯酯抗性基因型的卵到成虫存活率更低、卵到成虫发育时间更长、繁殖力更低。与 Unsel-Lab 种群相比,CTPR-Sel 种群的 S. litura 在 LC30 时的相对适合度较低(0.44),雄性/雌性寿命较短。CTPR-Sel 株系的繁殖参数,包括净繁殖率(R0)、内在增长率(rm)和有限增长率(λ),均低于 Unsel-Lab S. litura。这些研究结果表明,S. litura 对氯氟吡甲禾灵的抗性在个体和种群水平上都会产生适应性成本,这意味着从环境中移除选择剂可能会导致抗性降低和易感性恢复的机会减少。因此,目前的工作有助于确定有效的管理策略,以防止 S. litura 产生氯虫苯甲酰胺抗性。
Effect of Chlorantraniliprole on Life History Traits and Relative Fitness of Laboratory-Selected Resistant and Susceptible Populations of Spodoptera litura (Lepidoptera: Noctuidae).
Insecticides are widely used to control pests and improve agricultural yield. The use of indiscriminate amounts and persistent pesticides has not only resulted in insect pest resistance challenges but has also harmed non-target organisms and contaminated the environment. We assessed the cost-effectiveness of Spodoptera litura (Fabricius) resistance to chlorantraniliprole (CTPR) as part of insect resistance control programs. S. litura larvae were collected from the fields and treated with chlorantraniliprole for 15 generations. Compared to the unselected population (Unsel-Lab), the chlorantraniliprole-selected population (CTPR-Sel) of S. litura exhibited a resistance level of 98.23 times. The findings demonstrated that the chlorantraniliprole-resistant genotype had lower egg-to-adult survivability, longer egg-to-adult developing times, and lower fecundity than the chlorantraniliprole-susceptible genotype. Compared to the Unsel-Lab population, the CTPR-Sel population of S. litura had a poorer relative fitness (0.44) at LC30 and shorter male/female longevity. Demographic parameters, including net reproductive rate (R0) and intrinsic (rm) and finite rate of increase (λ), were lower in the CTPR-Sel strain than in Unsel-Lab S. litura. These findings demonstrate that chlorantraniliprole resistance in S. litura has fitness costs at the individual and population levels, implying that removing the selecting agent from the environment might result in less resistance and opportunities for susceptibility restoration. As a result, the current work could help to determine effective management strategies to prevent chlorantraniliprole resistance in S. litura.
期刊介绍:
Neotropical Entomology is a bimonthly journal, edited by the Sociedade Entomológica do Brasil (Entomological Society of Brazil) that publishes original articles produced by Brazilian and international experts in several subspecialties of entomology. These include bionomics, systematics, morphology, physiology, behavior, ecology, biological control, crop protection and acarology.
