为调查云南低纬高原地区蚜虫的病原真菌和寄生性天敌，在18-22°C、L：D为12：12的条件下，将3，553只甘蓝蚜、萝卜蚜和桃蚜的迁飞有翅蚜从空中诱集到黄色植物诱捕器上，在甘蓝叶片上单独饲养7-14 d。10种蚜虫病原真菌在1-7 d存活2.3d后，有19.2%的有翅虫被杀死。另外2.8%在存活4.9 d（范围1-11 d）后被烟蚜茧蜂（Aphidiusgifuensis）、疏枝小萤叶甲（Diaeretellaraestriella）、麻黄素（Ephedrusplagiator）和苹果小萤叶甲（Aesthidinusmali）等寄生蜂木乃伊化。真菌化有翅虫的死亡率最高（77.8%），其次为诺氏疫霉（P. nouryi）、费氏新合子霉（Neozygites fresenii）、生耳霉属（Conidiobiolus spp.）Planchoniana虫瘟霉（Entomophthora planchoniana）和Z.蚜虫的数量在减少。一种常见的有丝分裂孢子真菌蜡蚧蜡蚧菌（Lecanicilliumlecanii）在L.稻子有翅虫在雨季被困。然而，B。在旱季捕获的芸苔有翅虫偶尔被感染或寄生。死亡前的繁殖力的感染或寄生的有翅类保证成功的殖民化的植物，虽然大大减少，并显示了良好的拟合概率为一个给定的人均繁殖力和增加的平均大小的后代殖民地。在大多数菌落中，有翅传播的真菌病的传染性传播在14 d内引起高子代死亡率。研究结果首次揭示了低纬高原蚜虫病原菌的多样性以及病原菌和寄生蜂随寄主扩散飞行的传播规律。
To survey fungal pathogens and parasitoids of aphids in the low-latitude plateau of Yunnan, southwest China, 3,553 migratory alates of Brevicoryne brassicae, Lipaphis erysimi, and Myzus persicae were attracted to a yellow-plus-plant trap from air during a full-year period and individually reared on cabbage leaves for 7–14 d at 18–22°C and L:D 12:12. Among the trapped alates, 19.2% were killed by 10 species of aphid-pathogenic fungi after survival of 2.3 d (range, 1–7 d). Another 2.8% were mummified by the wasps Aphidius gifuensis, Diaeretella rapae, Ephedrus plagiator, and Aphelinus mali after survival of 4.9 d (range, 1–11 d). Most of the mycosed alates (77.8%) died from Entomophthorales predominated by Pandora neoaphidis (42.7%) and Zoophthora radicans (14.5%), followed by P. nouryi, Neozygites fresenii, Conidiobiolus spp., Entomophthora planchoniana, and Z. aphidis in decreasing frequencies. A mitosporic fungus, Lecanicillium lecanii, was found frequently in L. erysimi alates trapped in rainy season. However, B. brassicae alates captured in dry season were infected or parasitized very occasionally. The predeath fecundity of the infected or parasitized alates warranted successful colonization on plants, although greatly reduced, and was well shown by the fitted probability for a given fecundity per capita and the increasing mean size of their progeny colonies. Contagious transmission of the alate-borne mycosis in most of the colonies caused high progeny mortalities within 14 d. The results highlight for the first time the diversity of aphid pathogens and the spread of both pathogens and parasitoids with host dispersal flight in the low-latitude plateau.
