利用寄主抗性是防治害虫的长远措施。抗性材料鉴定上的成就,在很大程度上取决于大量种质资源鉴定和基因型改良的能力。利用害虫自然发生的条件进行品种抗虫筛选,通常由于害虫种群消长和分布的不均匀带来许多困难,也影响其可靠性。因此,发展和利用快速的人工接虫技术是成功地筛选抗虫品种的先决条件。在国际半干旱热带作物研究所(ICR-ISAT),建立了用田间人工接种1龄茎螟(Chilo partellus)幼虫的方法筛选抗虫品
The use of host resistance is a long-term measure to control pests. Achievements in the identification of resistant materials will depend in large part on the ability to identify and genotype a large number of germplasms. Insect pest species naturally occur under conditions of insect resistance screening, usually due to pest population growth and uneven distribution of many difficulties, but also affect its reliability. Therefore, the development and utilization of rapid artificial insects technology is a prerequisite for the successful screening of insect-resistant varieties. At the ICR-ISAT, an approach was developed to screen for insect-resistant products by artificial inoculation of Chilo partellus larvae in the field
