摘　　要：以沿海蝗区南大港水库为研究区域，通过2年野外调查旨在掌握东亚飞蝗Locusta migratoria manilensis（Meyen）产卵场所的选择。结果表明，飞蝗产卵适宜的植被覆盖度、土壤含盐量和土壤5cm含水量分别为0—30％、0．09％-1．99％和10．0％-20．0％，当植被覆盖度〉70％，土壤含水量〉30％或含盐量〉3％时，不再适合飞蝗产卵。土壤有机质和pH值不是影响飞蝗产卵选择的主要因素。与20世纪50年代的研究结果相比，飞蝗产卵时对土壤含水量和含盐量的耐受范围拓宽，对环境的适应能力增强。It was reported the oviposition site selection by Locusta migratoria manilensis （Meyen） at the Nandagang reservior in the coastal locust areas by two years field investigation. The results indicated the preferable ranges of vegetation coverage, soil water content at 5 cm depth, and soil salinity for L. migratoria manilensis oviposition were 0-30%, 10.0% - 20.0%, and 0.09% - 1.99%, respectively. The site with vegetation coverage more than 70%, soll water content at 5 cm depth more than 30%, or soil salinity more than 3% is no longer suitable for L.migratoria manilensis oviposition. Soil organic matter and pH value were not main factors affecting the locust oviposition selection. Compared with the results in the 1950s, L. migratoria manilensis at present shows wider tolerance ranges to soil water content at 5 cm depth and salinity, and becomes more adaptable to the envorinment.
