采用AC型电子记录系统 (EMS)对褐飞虱在非寄主植物稗草和具有抗性基因bph4的水稻品种Babawee上的取食行为进行了比较研究。结果表明 ,褐飞虱口针到达稗草韧皮部以前停止取食 ,这揭示了在稗草非韧皮部组织中存在拒食剂。而在抗虫品种上 ,口针到达韧皮部以后取食行为终止。因此 ,可以清楚地识别两类具有不同抑制取食抗性因子的抗性植物。分析白背飞虱产卵行为的电子记录表明 ,在大多数情况下 ,就旺盛生长的水稻植株的下半部分而言 ,白背飞虱产卵器插入植物组织中但不产卵。这表明旺盛生长的植株能诱导白背飞虱的产卵行为 ,但由于某些拒避性因素使整个产卵过程不能完成。因此 ,这一系统可以有效地识别具有产卵抗性的植物上行为序列中受到破坏的步骤。
The feeding behavior of the brown planthopper (BPN) on non-host plant barnyard grass and the rice variety Babawee with the resistance gene bph4 were compared using an AC-based electronic recording system (EMS). The results showed that the BPH needle stopped feeding before reaching the phloem of barnyardgrass, which revealed the presence of an antifeeding agent in non-phloem tissues of Echinochloa crusgalli. In insect-resistant varieties, the spikes reach the phloem later feeding behavior termination. Therefore, two types of resistant plants with different feeding resistance-inhibiting factors can be clearly identified. Electronic records that analyzed the oviposition behavior of Sogatella furcifera showed that in most cases, the white-backed planthopper ovipositor was inserted into the plant tissue in the lower half of the well-to-grow rice plant without spawning. This indicates that the vigorous growth of plants can induce oviposition behavior of Sogatella furcifera, but the entire spawning process can not be completed due to some repellent factors. Therefore, this system can effectively identify the damaged steps in the behavior of oviposition-resistant plants.
