Development of Artificial Diet for Erigonidium graminicolum(sundevall)

[Objective] This study was to find out the artificial diet formula for Erigoni- dium graminicolum （Sundevall） to realize its indoor artificial breeding. [Method] Using orthogonal decomposition method, the diet most suitable for the normal and quick growth of Erigonidium graminicolum （sundevall）, was developed by adding different species and different proportions of fresh insects to the artificial diet based on the formula of total nutrient solution proposed by Zhao Jing-zhao. [Result] The most suit- able formula for the development and growth of Erigonidium graminicolum （Sundevall） is 10 ml of egg white, 2 g of honey, 2 g of sucrose, 10 ml of water, 5 g of Ci- cadella viridis, moderate amount of cornmeal, compound vitamin B1 and vitamin C1. [Conclusion] The development of new type artificial diet can provide timely and nec- essary material premise for its large-scale indoor propagation.

盐酸土霉素对大青叶蝉转氨酶活性的影响

用盐酸土霉素处理大青叶蝉(Cicadella viridis)1日龄若虫,检测处理后5、15 d大青叶蝉若虫和成虫期3种转氨酶(谷丙转氨酶、谷草转氨酶和谷氨酰胺合成酶)的活性变化。结果表明,大青叶蝉的3种转氨酶活性在盐酸土霉素处理后5 d显著增强,而在处理后15 d谷氨酰胺合成酶和谷草转氨酶活性显著降低,但谷丙转氨酶的活性显著上升。大青叶蝉雄虫的3种转氨酶活性显著降低,雌虫谷丙转氨酶的活性变化不明显,但谷氨酰胺合成酶和谷草转氨酶的活性均显著下降。
