Abstract

The investigated results by making investigation routes and survey points in 6 habitats types in Pu Luong Nature Reserve have identified that there were 16 species o f ladybird belonging 10 genus, in which genus Henosepilachna has the highest number o f species (4 species) accounting fo r 25% and each o f Cycloneda, Epilachna and Micraspis have 2 species, accounting fo r 12.5% and o f the 6 remaining genus, each has only one species, accounts fo r 6.25%. The similarity index between habitats ranged from 0 to 0.89, the highest (SI = 0.89) is between shrub scrub alternating secondary timber tree with around villages and swidden field, the lowest (SI = 0) is between bamboo forest with primary forest and bamboo forest with secondary forest. The number o f indicator species and detector species appear mainly in the around the village and swidden field, whereas, there is no indicator species and detector species appear in the primary forest.
