Effect of nitrogen on Passiflora suberosa L. (Passifloraceae) and consequences for larval performance and oviposition in Heliconius erato phyllis (Fabricius) (Lepidoptera: Nymphalidae).

The present study examines the influence of nitrogen on growth rates, morphological and nutritional characteristics of Passiflora suberosa L., and the corresponding consequences for Heliconius erato phyllis (Fabricius) growth and oviposition. The treatments consisted of different nitrogen doses (0, 150 and 300 mg L(-1)) applied to the soil.
