研究了外源昆虫蜕皮激素和保幼激素对松材线虫（ Bursaphelenchus xylophilus）繁殖的影响。用10-6 g/mL到10-9 g/mL的7个连续几何级数浓度的保幼激素或蜕皮激素处理线虫。保幼激素处理6 d及以后的松材线虫繁殖数量显著高于空白对照和仅提供灰葡萄孢为营养的对照（ P＜0．05）。在观察时间内，保幼激素浓度以5×10-7 g/mL为线虫繁殖量的最高峰值，其线虫繁殖数量显著高于其他浓度（ P＜0．05）。蜕皮激素对松材线虫的繁殖同样具有明显的促进作用，激素处理6 d及以后的松材线虫繁殖数量显著高于两组对照（ P＜0．05）。在观察时间内，蜕皮激素浓度以5×10-7 g/mL为线虫繁殖量的最高峰值，且明显高于其他浓度的处理（P＜0．05）。此外还发现保幼激素和蜕皮激素在浓度为5×10-9 g/mL处存在线虫繁殖的次高峰。

The effects of the insect 20-hydroxyecdysone and juvenile hormoneⅢ on reproduction of pine wood nematode,Bursaphelenchus xylophilus,were investigated.The nematodes were treated with 7 continuous geometric concentration series of 20-hydroxyecdysone or juvenile hormone Ⅲ.The numbers of the nematodes treated with 20-hydroxyecdysone or juvenile hormone Ⅲfrom the 6th day to the 9th were significantly higher than those of the blank control and the control treated with only the nematode food ,Botrytis cinerea ( P<0.05) . During the observing period the peak of the reproduction was at 5 ×10-7 g/mL of the ecdysone and the peak value was significantly higher than those in the other concentrations .During the observing period the peak of the number of the nematodes was at 5×10-7 g/mL of the two hormones and it was significantly higher than those in the other concentrations of the hormones .The second peak of the nematode number was also found at 5 ×10-9 g/mL in both the ecdysone and the juvenile hormone .
