Abstract	We examined the effects of diet mixture on the nymphal performance of a polyphagous grasshopper Parapodisma subastris Huang by developing the first-stadium nymphs with either single or various combinations of plants occurring in their natural habitat. Intrinsic quality in terms of nymphal survival differed largely across the 16 plant species. However, even combinations of the six worst quality plants (survival 10% or less in each) greatly improved nymphal survival when compared to that of superior quality plants (more than 70% survival). In contrast, the addition of either of two inferior plants (more than 10% and less than 40% survival) to the superior plant affected neither the survival nor the adult mass. Thus, diet mixture can be particularly important when only low quality plants are available. The adaptive significance of diet mixture was discussed in relation to the habitat flora and foraging habits of the grasshopper in the present study.
