茧色遗传(genetics of cocoon colours)
茧色遗传(genetics of cocoon colours)桑蚕的遗传现象有之一。宋应星(1637)在《天工开物》一书上就有记载。茧色分白色茧和着色茧两大类，着色茧中又分黄茧系和绿茧系两类。1.黄茧类：有金黄、浅黄、藁色、肉色、淡红等茧色。一般情况，黄茧的蚕是黄血，白茧蚕血无色，但发现黄血白茧蚕，因知黄茧和黄血是由不同的基因控制的。金黄茧基因(C)必须与黄血基因(Y)互补，才表现外层金黄色。2.绿茧类：有各种浓度差异的绿色茧和淡竹色茧。中国地方种的碧莲及大造是典型的绿茧。中国白茧种和日本白茧种杂交的子代，往往产生淡竹色茧，即日本称做的笹茧。淡竹色茧有Ga和Gb两种基因，单独存在时各现白色，通过杂交，两基因互相补足，产生淡竹色。绿茧色素是属于类黄酮，在蚕体内合成的蚕素(bombycin)为桑叶中所没有的。绿茧色素分布在全部丝物质中，在绿茧中含量多，即使在黄茧中也存在，也有各种茧内部含有绿茧色素。栎粉舟蛾(tangled prominent of oak)柞树害虫之一。属鳞翅目，舟蛾科，学名为Fentonia ocypete Bremer，别名旋风舟蛾、细翅天社蛾。形态 成虫前翅暗灰褐色，无顶角斑；外线双道，内方一条近前缘外拱，外方一条外衬灰白色边；横脉处有一灰黄色圆点，该圆点与外线间有一大形黑褐色斑。雄蛾触角栉形，末端2/5成线形。雌蛾触角线形，黑色。成虫体长18-25mm，翅展45-58mm。卵黄白色，半球形，直径1.1mm。老熟幼虫体长35-40mm，头部肉红色，有4条短紫红色和8条黑线。胸侧绿色，腹部背方及体侧有紫红色与黑色细线组成的花纹；背方与腹侧具少数黄斑点。蛹黑褐色。习性 一年发生一代，以蛹越冬。在辽宁省翌年7月份羽化为成虫，晚间交尾、产卵，白天潜伏在树上。有较强的趋光性。卵产在柞叶背面，分散产卵，每一叶片产卵几粒。一头雌蛾产卵150-450粒。经5-7天孵化为幼虫。一龀龄幼虫于7月上中旬出现，分散生活，多在叶背取食，以后转移到叶缘咬食叶片。小龄幼虫能吐丝下垂。幼虫4龄以后食叶量显著增加，受触动能散出强烈刺激性物质。8月底至9月间幼虫老熟，体色转淡，于树下土中吐丝粘结土粒，作薄茧化蛹越冬。分布、为害 栎粉舟蛾分布于辽宁、吉林、黑龙江、河北、山东、湖南、四川等省。为害辽东柞、蒙古柞。1984年辽宁省凤城蚕区大发生，吃光大片树叶，蚕茧减产。天敌 有大星步甲、螽斯、线虫、赤眼蜂及微孢子虫等。防治 成虫期用黑光灯诱杀。幼虫4龄以前喷撒敌百虫、敌敌畏、辛硫磷等药剂防治。须过了残毒期才能放养柞蚕。
