Population Dynamics and Life Cycle of Teak Defoliator Hyblaea Puera Cramer., (Lepidoptera: Hyblaeidae) in Lao People's Democratic Republic

Forest lands in Lao People's Democratic Republic (Lao P.D.R) are largely owned and administered by the government. Teak (Tectona grandis) is one of the important hardwood species planted extensively in plantation in the northern part of Lao P.D.R for commercial purposes, but teak tree has numer...
