Ultrastructure and element composition of the egg shells in eastern reef heron;
岩鹭卵壳的超微结构及其元素组成
The surface and seciton of the egg shell of giant silkworm (Antheraea Yamama),oak silkworm (Antheraea Pernyi)and their F 1 hybrids were observed with scanning electron microscope.
应用扫描电镜观察了天蚕（ＡｎｔｈｅｒａｅａＹａｍａｍａｉ），柞蚕（ＡｎｔｈｅｒａｅａＰｅｒｎｙｉ）及种间杂交Ｆ１代卵壳的表面及断面构造。
The egg shells of seven species of Altica, A.
结果表明7种卵在卵的大小、卵壳表面纹饰的形状、纹饰突起的程度、孔洞的多少等均存在明显差异。
Before hatching, white and waxen outer layer and yellow inner layer were derived from the chorion; during hatching, the larva bored directly into phloem from the bottom part of the egg adhered to the.
结果发现:卵初产时为乳白色,后变为浅褐色并开始皱缩,末期变为黄褐色,孵化前部分卵壳分离为白色蜡质外层和黄褐色内层两层;幼虫孵化的同时直接从卵壳贴近树皮的一侧蛀入韧皮部,同时将大量虫粪排入卵壳;幼虫随着虫龄的增加钳状突的阶数和口上片的宽度发生有规律的变化,末龄幼虫在木质部作一椭圆形蛹室化蛹,身体的头部和尾部以3∶7的比例对折;化蛹前的幼虫经历一个身体缩短的预蛹状态;刚化的蛹为乳白色,复眼颜色与身体相似,化蛹后蛹的颜色逐渐变为淡黄色,复眼颜色变为浅红褐色,后期复眼变为红褐色,口器变黑,羽化前蛹的复眼、口器和体表全部变黑;羽化过程中,成虫体表的膨胀导致蛹表皮脱裂,前翅变黑和腹部背面变成碧蓝色后羽化成完整的成虫。
