摘要

昆虫产卵过程对寄主植物的直接刺激包括产卵器的机械损伤和卵表面物质带来影响，这些刺激是启动植物诱导抗虫性的重要途径。通过对褐飞虱产卵处理后水稻植株内胰蛋白酶抑制剂（BBPI）合成酶基因的表达量及物质含量的测定，对比褐飞虱取食和机械损伤处理，发现褐飞虱产卵能够诱导水稻BBPI合成酶基因的表达和BBPI物质的生成。处理后6 h，12 h，水稻 BBPI 表达量显著高于取食和机械损伤处理；产卵诱导的BBPI物质含量显著高于正常水稻。褐飞虱产卵诱导水稻启动〖WTBX〗BBPI〖WTBZ〗表达和物质合成表明，与取食危害类似，水稻同样会对褐飞虱产卵刺激产生响应，启动相应的植物防御体系，进而达到阻滞褐飞虱危害的目的。

Abstract

Physical damage caused by ovipoistor and chemicals attached on the surface of insects’ eggs are both included in the direct stimulis of insects’ oviposition in the host plants which are the most important factors in inducing a wide range of defesive responses in plants. This article found that compare with feeding and physical treatments

oviposition of Brown Planthopper (BPH

Nilaparvata lugens

(St.l)) can induce the expression of BBPI（Bowman Birk Proteinase Inhibitor） synthetase gene and cause the production of BBPI. Both of the expression levels of BBPI with oviposition treatment after 6 h and 12 h are higher than those of feeding and physical treatments. The results discribed above indicate that as to feeding damage

the rice can react to egg deposition of BPH and induce defensive responses

therefore conctrol the further damage of BPH.
