[Effects of different corn varieties on development and reproduction of ].

To understand the damage capability of the invasive pest on diffe-rent corn varieties in China, we evaluated survival fitness of on three varieties of sweet corn (., Suitian No.1, Zhengtian 68, and Huajintian No.1) and three varieties of waxy corn (., Jingkenuo 2000, Guangheitiannuo, and Guangnuo No.1) by constructing life table for all populations. The correlation of biological parameters of to the main nutrients and crude fiber content in corn leaves were analyzed. Results showed that the larva survival rate, pupal weight, and production of on sweet corns were significantly higher than those on waxy corns. The intrinsic rate of increase () of on the sweet corns ranged from 0.1566 to 0.1843, and the net reproductive rate () ranged from 187.97 to 353.35, being higher than those reared on the waxy corns ( was from 0.0998 to 0.1465, and was from 25.89 to 95.34). reared on the sweet corns had higher population growth ability than those reared on the waxy corns. The content of main nutrients such as vitamin C, starch, soluble sugar, protein, fat, total amino acids, and crude fiber in the sweet corn leaves were higher than those in the waxy corn leaves. There were positive correlations between of to the contenst of vitamin C, starch, soluble sugar, protein, and crude fiber in corn leaves. The results indicated that reared on the sweet corn leaves had higher survival fitness than those reared on the waxy corn leaves.
