Food consumption, utilization and reproduction of the teak defoliator, Hyblaea puera, show age specific host leaves (young, mature and senescent) preferences. The amount of food consumed, total egg output and adult longevity were maximum on young leaves reared H. puera than reared on other age of leaves. The efficiency of ingested (ECI) and digested (ECD) food were considerably reduced on senescent leaves.
Murugan et al. (Sun,) studied this question.
