Objective To examine the morphological characteristics and differential gene expression of Aldrichina grahami egg in the different developmental stages. Methods After Aldrichina grahami layed eggs( 0 h),the eggs w ere collected every 4 hours until the eggs hatched into larvae. The morphological characteristics of Aldrichina grahami egg in different developmental stages w ere observed w ith scanning electron microscopy. The total RNA the eggs at every develop-mental stage w as extracted. The expression level...
