【目的】 九香虫Aspongopus chinensis是一种在我国应用历史悠久、价值极高的药食同源重要资源昆虫，为明确不同寄主植物对九香虫生长发育的影响，以及其规模化人工饲养提供基础参考依据。【方法】 选择葫芦科佛手瓜、南瓜、苦瓜和黄瓜4种瓜类植物为供试材料，将野外采集的初代九香虫在室外饲养繁殖后，以次代九香虫为供试虫源，观察记录九香虫若虫不同龄期的生长发育历期、存活率，测量九香虫成虫体长、体宽、体重、前胸背板长和前胸背板宽5个外部形态指标。【结果】 （1）黄瓜为寄主植物的九香虫在达到2龄若虫时全部死亡；以苦瓜为寄主植物的九香虫除1龄若虫外，其余4个龄期的发育历期都比佛手瓜和南瓜为寄主植物的长；以佛手瓜为寄主植物的九香虫除2龄和4龄若虫外，其余龄期的发育历期都比南瓜为寄主植物的短；从九香虫整个若虫发育阶段来看，以佛手瓜为寄主植物的生长发育总历期最短，苦瓜为寄主植物的最长。（2）九香虫若虫在不同寄主植物饲养下的存活率表现为佛手瓜（83.33%）>南瓜（63.33%）>苦瓜（36.67%），以佛手瓜为寄主植物的存活率最高。（3）以佛手瓜和南瓜为寄主植物的九香虫成虫在体长、体宽、前胸背板宽和体重4个形态指标方面与苦瓜为寄主植物的均存在极显著差异（P<0.01），在前胸背板长方面存在显著差异（P<0.05）；以佛手瓜与南瓜2种寄主植物饲养的九香虫成虫5个形态指标均无显著差异（P>0.05）。【结论】 4种瓜类植物对九香虫若虫生长发育历期和成虫外部形态特征均有显著影响。在保山地区，当室外饲养繁殖次代九香虫寄主植物发生变化时，利用南瓜为寄主植物饲养九香虫的效果要优于黄瓜和苦瓜，而佛手瓜仍是九香虫较理想的寄主植物。

 [Aim]  To determine the effects of four different cucurbit host plants on the growth and development of Aspongopus chinensis, an insect with high medicinal and food value in China, with the aim of improving the captive propagation of this species. [Methods]  Four gourd plants from the Cucurbitaceae family, including Sechium edule, Cucurbita moschata, Momordica charantia and Cucumis sativus, were selected as experimental materials. After the primary generation of A. chinensis was captured in the wild and bred in outdoor conditions, the second generation of insects was used for the study. The growth and development stages, survival rate, and five external morphological indicators-body length, body width, weight, pronotum length, and pronotum width-were observed and recorded for nymphs of different ages. [Results]  (1) All nymphs on C. sativus host plants had died by the 2nd instar. Except for the 1st instar nymphs, the developmental period of all four instars feeding on M. charantia was longer than that of those feeding on S. edule and C. moschata. Except for the 2nd and 4th instar nymphs, the developmental periods of nymphs raised on S. edule were shorter than those raised on C. moschata. Considering the entire developmental period, nymphs raised on S. edule had the shortest total period of growth and development, whereas those raised on M. charantia had the longest. (2) The survival rates of nymphs reared on different host plants can be ranked as follows: S. edule (83.33%) > C. moschata (63.33%) > M. charantia (36.67%). (3) There were highly significant differences (P<0.01) between the body length, body width, prothoracic dorsal plate width, and body weight, of adults raised on S. edule and those raised on C. moschata, and significant differences (P<0.05) in the indicator prothoracic dorsal plate length between those raised on S. edule and M. charantia. [Conclusion]  Host plant variety had a significant effect on the growth and developmental period of nymphs and adult external morphology. The results indicate that, of the five host plants evaluated, S. edule is the best for rearing A. chinensis, and C. moschata is preferable to C. sativus or M. charantia.
