摘　　要：以枸杞红瘿蚊(Jaapiella sp.)幼虫为研究对象,室内开展了不同浓度斯氏线虫对枸杞红瘿蚊幼虫侵染能力及存活能力试验,以期为枸杞红瘿蚊的生物防治提供理论依据。结果表明,15 g/20 mL浓度的斯氏线虫对枸杞红瘿蚊侵染能力较强,致死效果明显;以枸杞红瘿蚊虫体及体液为培养基的斯氏线虫存活率显著高于清水对照。The larvae of Jaapiella sp.were studied in this paper,experiments on infection and survival of different concentrations of Steinernema against Jaapiella sp.larvae were conducted in laboratory,in order to provide theoretical basis for biological control of Jaapiella sp.The results showed that the concentration of 15 g/20 mL of Steinernema had a strong infection ability against Jaapiella sp.,and the lethal effect was obvious.The survival rate of Steinernema cultured in the culture medium was significantly higher than that cultured in water.
