摘要

Silicon (Si) supplementation is known to cause the resistance of plants to insect herbivores. There is a lack of clarity regarding the methods by which silicon influences herbivore performance. We assessed different silicon concentrations (0, 125, 250 & 500 mg L−1) on Si accumulation, development and mandibular wear of insect herbivore, Mythimna separata on wheat. Higher Si concentrations decreased oviposition rates, weight gain, larval biomass and consumption rates in M. separata. On comparing with control, increased Si levels resulted in higher percent mortality, longer development and greater mandibular wear. Higher Si concentrations lead to abrasiveness and hardness of leaves and poor nutritional quality of the leaves which in turn affect the performance of herbivore. Thus, Si supplementation could be an alternative to insecticides and one of the potential ways of controlling insect pests in Integrated Pest Management Programs.
