这个研究重点是放在观察那些对黑尾叶蝉的生长和存活给予不良影响的水稻品种的抵抗性本质方面,迄至现时为止获得的结果表明,印度型水稻品种存在着一种抵抗性,对黑尾叶蝉在它们上面取食有不良影响。每个详细检查过的抵抗性水稻品种,几乎同一个样子,表明对黑尾叶蝉有不良影响。无论是若虫或成虫～到达抵抗性水稻品种上不要好几天就遭到较高死亡。因此,雌成虫在整个植株生长期内,繁殖力大大降低。就已得到的结果来看,利用水稻抵抗性品种去压抑黑尾叶蝉的种群和损害的可能性显然是有的,因此,进一步的研究是需要的。
The focus of this research has been on observing the essential nature of the resistance of rice cultivars that adversely affect the growth and survival of the black-tailed leafhopper, and the results so far achieved indicate that there is a resistance in the Indian rice varieties, Nephotettix cincticeps have a detrimental effect on their feeding. Each well-examined, resistant rice variety, almost identical, showed an adverse effect on the black-tailed leafhopper. Whether nymphs or adults ~ reach resistant rice varieties within a few days they suffer higher deaths. Therefore, female adults in the whole plant growth period, fertility greatly reduced. As far as the results obtained are concerned, it is clear that there is an obvious possibility of using rice-resistant varieties to suppress the population and damage of the rice leafhoppers. Therefore, further research is needed.
