Effects of Total Ginsenosides on the Feeding Behavior and Two Enzymes Activities of Mythimna separata (Walker) Larvae

Table 1

Nonselective antifeeding ratio of different total ginsenoside concentrations on 4th-instar M. separata larvae.

Data are presented as the means ± SE. Means in the same column followed by different letters are significantly different at the level . Prior to analysis of variance (SPSS 18.0), the homogeneity of variance was tested in each statistic test.
