Braz. j. biol; 79 (1), 2019
Abstract The development and reproductive potential of Spodoptera eridania (Stoll, 1782) (Lepidoptera, Noctuidae) was compared on natural and artificial diets. Its biology was determined under laboratory conditions, providing an artificial diet, leaves of white clover and the peach cultivar 'Chimarrita'...

Differential formononetin content in cultivars and experimental lines of red clover (Trifolium pratense L. ) plants affect the feeding behaviour of Hylastinus obscurus (Coleoptera: Curculionidae)
