摘要
通过野外调查和实验室内培养观察,研究核桃皑粉蚧的生物学特性及其与暗褐网柄牛肝菌形成的菌腔虫瘿的形态结构.调查发现:在西双版纳地区,核桃皑粉蚧在凤凰木、含羞草、银合欢和粉叶金花等4种植物的根表面与暗褐网柄牛肝菌的菌丝形成菌腔虫瘿;菌腔虫瘿在植物根部单生、簇生或串生,呈圆形或椭圆形,初期黄褐色,中后期变为黑褐色至黑色;核桃皑粉蚧的繁殖能力强,无孤雌生殖现象.产卵雌虫虫态包括:卵、1龄若虫、2龄若虫、3龄若虫和成虫;雄虫虫态包括卵、1龄若虫、2龄若虫、蛹和成虫.雌虫寿命约为雄虫的2倍,不产卵雌虫寿命通常长于产卵雌虫.菌腔虫瘿的腔壁完全由牛肝菌菌丝构成,核桃皑粉蚧以菌腔为栖息场所,以寄主植物的汁液为食物来源.
Field investigation and laboratory cultivation were performed to study the biological characteristics of Crisicoccus marsumotoi and the structure of fungus-insect gall composed of C. marsumotoi and Phlebopus portentosus. By the field investigation in Xishuangbanna, a special insect gall, which was termed as fungus-insect gall in this paper, was discovered. The fungus-insect gall was formed by C. marsumotoi and P. portentosus on the root surface of Delonix regia, Mimosa pudica, Leucaena glauca and Mussaenda hybrid. On the root surface of host plants, the fungus-insect gall usually formed a round or oval shape, or clustered. It was yellowish brown in the beginning, and later turned to be blackish brown or black. C. matsumotoi had huge reproductive potential, but the parthenogenetic reproduction was not detected. In reproductive female, five developmental stages, i.e., egg, 1st, 2nd and 3rd instar nymph and adult, were observed. The developmental stages of male included egg, 1st and 2nd instar nymph, pupa, and adult. The life span of female （50-59 d） was about twice as long as male （24-27 d）, and sterilized female generally lasted longer than the reproductive female. The wall of fungus-insect gall was entirely formed by hyphae of P. portentosus. C. matsumotoi utilized the cavity of fungus- insect gall as habitat, and the juice of host plants as food resource.
