Host Plant Biochemical Diversity, Feeding, Growth and Reproduction of Teak Defoliator Hyblaea puera (Cramer) (Lepidoptera: Hyblaeidae)

Key Points

The research examines how the age of host leaves affects food consumption, growth, and reproduction of Hyblaea puera.
Evaluated food preferences of H. puera on different ages of host leaves (young, mature, senescent).
Measured total egg output and adult longevity across leaf types.
Calculated efficiency of ingested and digested food (ECI and ECD) on different leaf ages.
H. puera showed the highest food consumption, egg output, and longevity on young leaves.
Efficiency of ingested and digested food was significantly lower on senescent leaves.
Age of host leaves markedly influenced the overall growth and reproduction metrics of H. puera.

Abstract

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.
