| 开展枸杞红瘿蚊Gephyraulus lycantha Jiao & Kolesik羽化生物学特性研究，探讨不同土壤因子对其出土羽化的影响，旨在为其有效防控提供理论指导。在室内模拟条件下，设置不同土壤含水量（0、5%、10%、15%、20%、25%、30%）、土壤基质（沙土、壤土、沙壤土）、土壤容重（1.0 g/cm3、1.2 g/cm3、1.4 g/cm3）和土壤深度（5 cm、10 cm、15 cm、20 cm、25 cm），调查枸杞红瘿蚊老熟幼虫的出土羽化率及逐日出土羽化情况。结果显示枸杞红瘿蚊在土壤中原位完成蛹期发育后，以后期蛹形态钻出土壤表面后完成羽化。不同的土壤因子显著影响枸杞红瘿蚊成虫出土羽化，土壤含水量为15%时，枸杞红瘿蚊出土羽化率最高为13.75%，在次条件下，沙壤土最适合枸杞红瘿蚊出土羽化。枸杞红瘿蚊仅在1.0 g/cm3容重下可以正常出土羽化，超过1.2 g/cm3则无法出土羽化；土壤深度为5 cm时枸杞红瘿蚊出土羽化率显著高于其余土壤深度处理。本研究表明枸杞红瘿蚊出土羽化最适宜的条件为土壤含水量为15%、土壤基质为沙壤土、土壤容重为1.0 g/cm3、土壤深度为5 cm。 |

| The eclosion biological characteristics and effects of soil factors on its emergence and eclosion of Gephyraulus lycantha Jiao & Kolesik were researched, with the aim of providing theoretical guidance for effective control of this pest. Under indoor simulation conditions, different soil moisture conditions (0%, 5%, 10%, 15%, 20%, 25%, 30%), soil matrixes（sandy soil, loam soil, sandy loam soil), soil bulk densities (1.0 g/cm3, 1.2 g/cm3, 1.4 g/cm3) and soil depths (5 cm, 10 cm, 15 cm, 20 cm, 25 cm) were performed to investigate the eclosion rate and daily eclision rate of fully-grown larvae of G. lycantha. The results showed that G. lycantha completed its pupal development in situ in the soil, and completed eclosion after the late pupal emerged from the soil surface. Different soil factors significantly affect the emergence and eclosion of G. lycantha. When the soil moisture content is 15%, the highest rate of eclosion is 13.75%. Under this condition, sandy loam soil is most suitable for emergence and eclosion. G. lycantha can emerge normally only under the bulk density of 1.0 g/cm3, and cannot emerge beyond 1.2 g/cm3. The emergence rate of G. lycantha at a soil depth of 5 cm is significantly higher than that of other soil depth treatments. This study indicated that the most suitable conditions for the emergence of G. lycantha were soil moisture content of 15%, soil matrix of sandy loam, soil bulk density of 1.0 g/cm3, and soil depth of 5 cm.The results showed that the wolfberry red gall midge completed its pupal development in situ in the soil, and completed eclosion after the late pupal emerged from the soil surface |
