Abstract
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 numerous diseases, and insect
pests which cause damage to the teak plantation. Teak defoliator Hyblaea puera is an
important pest of teak in Lao P.D.R. It occurs every year during May to July when
the tree flushes leaves. This study was conducted in the natural teak forest and teak
plantations within two provinces i.e. Xayabury and Luang Prabang. This study
investigated the population dynamics and distribution of the insect in different teak
plantations, and its life cycle.

teak defoliator H puera occurred in early May when the teak developed new leaves,
