松艺夜蛾(Hyssia violascens Hampson)属鳞翅目夜蛾科,以幼虫取食马尾松针叶。1984年该虫在我省宁德、建阳、福州等地猖獗成灾,被害马尾松林远看似火烧状,损失严重。这种害虫的生物学特性及防治方法,国内尚未见报道。为此,我们于1984—1985年在闽侯、霞浦等县观察了该虫的生物学特性并进行了防治试验. 一、形态特征成虫:雌蛾体长16—17毫米,翅展37—38毫米,触角丝状。雄成虫体长14—16毫米,翅
Spodoptera nymphalis (Hyssia violascens Hampson) is a Lepidoptera nymphalidae, feeding larvae pine needles. In 1984 the insects rampant in Ningde, Jianyang, Fuzhou and other places in the province, the massacre of Pinus massoniana fire seems far, the loss is serious. The biological characteristics of pests and prevention methods, has not been reported in China. To this end, we observed the biological characteristics of the insect and conducted control tests in Minhou, Xiapu and other counties from 1984 to 1985. I. Morphological characteristics Adult: Female moth body length 16-17 mm, Wing Span 37-38 Mm, antennae filiform. Male adult body length 14-16 mm, wings
