在厦门海区对虾养殖内外环境中，电镜观察发现了杂色花蛤肝胰腺的一种杆状病毒和两种球状病毒。杆状病毒大小为（８５～９０）ｎｍ×（２４０～２６４）ｎｍ，有包膜，存在于细胞核中，细胞质可见。一种球状病毒直径为７０～８０ｎｍ，有包膜，存在于细胞质中．另一种球状病毒直径为９５～１２０ｎｍ，有包膜，存在于细胞核中。用免疫酶组织化学法检测表明，杂色花蛤所带杆状病毒与ＢＭＮＶ有抗原性正相关，其检出率随季节变化，暗示自然生长且感染病毒的杂色花蛤可能是日本对虾杆状病毒病的传染源。
In Xiamen sea area shrimp culture inside and outside the environment, electron microscopy found a variegated Hepatopancreas a baculovirus and two kinds of spherical virus. Baculovirus size (85 ~ 90) nm × (240 ~ 264) nm, a capsule exists in the nucleus, the cytoplasm can be seen. A spherical virus with a diameter of 70 ~ 80nm, a capsule exists in the cytoplasm. Another spherical virus has a diameter of 95-120 nm and is enveloped and exists in the nucleus. Immunohistochemistry showed that there was a positive correlation between the antigenicity of BMNV and the baculovirus carried by Helicoverpa armigera, and the detection rate varied with the seasons, suggesting that the natural variegated clam infected with the virus may be the Japanese shrimp stem The source of the virus infection.
