摘要

斜紋夜蛾之核多角體病毒，可感染斜紋夜蛾之脂肪體、眞皮及氣管被膜細胞。病毒在細胞核內複製，而在細胞質內亦可見。接種2天後，脂肪體細胞核腫脹。接種3天後，脂肪體細胞充滿空胞。接種4天後，有些脂肪體細胞膨大及體積增加，有些脂肪體細胞破裂，釋放多角體病毒於體腔中。真皮及氣管被膜細胞的組織病理變化過程與脂肪體細胞變化相若。

The nuclear polyhedrosis virus of Spodoptera litura did infect fat body, epidermal and tracheal matrix cells of S. litura. The virus replicated in nucleus and could also found in cytoplasm. The nuclear materials of fat body cells enlarges 2 days after inoculation treatment. The fat body cells were filled with many large vacuoles by 3 day posttreatment. Some of infected fat body cells were distended and many polyhedra were released into the body cavity from some disrupted cells by 4 day posttreatment. Histopathological changes occurred in epidermal and tracheal matrix cells were similar to that of fat body cells.
