Eurema hecabe mandarina

During the course of screening plants for insect antifeedants, the extract of the bulbs of Lycoris radiata Herb, was found to exhibit antifeeding activity when tested against the larvae of the yellow butterfly Eurema hecabe mandarina (61). 

Pinitol (63) is a feeding stimulant for the larvae of the butterfly, Eurema hecabe mandarina and also inhibits Heli-coverpis zea larval growth in soybeans (Ley et al., 1987). 

Widely distributed in plants. Produced on a large scale from the heartwood of Pinus lambertiana. Chiral synthetic precursor. Shows hypoglycaemic and antidiabetic activity. Feeding stimulant for larvae of butterfly Eurema hecabe mandarina, inhibitor of Heliothis zea larval growth. Mp 185-186°. Mg +67 (c, 2.5 in H2O).
