| 白刺夜蛾Leiometopon simyrides是荒漠植物白刺的重要害虫, 为明确寄主植物对白刺夜蛾生长发育的影响, 以便对其进行科学监测和防控，本研究在27℃下, 利用3种寄主植物(大果白刺、泡泡刺、唐古特白刺)饲养白刺夜蛾, 观察记录白刺夜蛾幼虫的取食量、各阶段的发育历期、存活率、羽化率、雌雄性比和成虫寿命等生物学特性, 同时测定各寄主植物叶片的营养和次生代谢物质含量。结果表明, 白刺夜蛾幼虫取食大果白刺叶片的总量最少, 取食唐古特白刺的量最多。取食唐古特白刺的白刺夜蛾幼虫发育历期最短, 其次为取食泡泡刺, 取食大果白刺时历期最长。取食泡泡刺和唐古特白刺后, 白刺夜蛾幼虫的存活率和羽化率较高, 取食大果白刺存活率最低, 且无成虫羽化。在唐古特白刺上, 白刺夜蛾雌虫占比较高, 成虫寿命较长。大果白刺的叶片总酚含量和简单酚含量最高, 各营养物质含量最低, 不利于白刺夜蛾的生长发育;唐古特白刺和泡泡刺酚类物质含量较低, 营养物质含量较高, 较适宜白刺夜蛾的生长发育和繁殖。唐古特白刺为白刺夜蛾的最适宜寄主植物, 其次为泡泡刺。 |
| 英文摘要: |
| Leiometopon simyrides is an important leaf-feeding pest insect of Nitraria spp. To explore the influence of host plants on the growth and development of L. simyrides and provide a foundation for monitoring and controlling this pest, Nitraria roborowskii, N. sphaerocarpa and N. tangutorum were used to raise L. simyrides at constant temperature 27℃, and the biological characteristics of L. simyrides, such as the developmental duration, survival rate at various developmental stages, emergence rate, sex ratio and longevity of adult were observed and recorded. At the same time, the contents of nutrient and secondary metabolites in the leaves of three host plants were measured. The results showed that the total leaf consumption was the least when L. simyrides fed with N. roborowskii, and the most on N. tangutorum. The developmental duration of L. simyrides was the shortest when fed with N. tangutorum, followed by those fed with N.sphaerocarpa, and the developmental duration was the longest when fed with N.roborowskii. The survival rate of larvae and emergence rate of L. simyrides were higher when fed with N. sphaerocarpa and N. tangutorum. The survival rate of larvae was the lowest without adult emergence when fed with N. roborowskii. The female adult proportion of L. simyrides was the highest when larvae were fed with N.tangutorum, while the adult longevity was the longest. The contents of total phenol and simple phenol in N. roborowskii leaves were the highest, and the lowest in N. tangutorum. The content of nutrients in N. roborowskii leaves was the lowest, but higher in N. tangutorum and N. sphaerocarpa. N. tangutorum and N. sphaerocarpa were suitable for the growth, development and reproduction of L. simyrides. N. tangutorum was the optimum plant for L. simyrides, followed by N. sphaerocarpa. |
