Biomes are interdependent. Plant communities relate to
physical properties of environment as: temperature, humidity, solar
radiation Those physical properties change with altitude and vary the
structure of plant communities. Plant are food of insects and have an
important role in the diversity and distribution of insects. Study on
responding of herbivore with the change of plant communities in
altitude will help us over the understand about relationship
interdependent each other in the ecosystem.
Chrysomelidae is the biggest family in Coleoptera order. Their
food are plant, therefore Chrysomelidae relates to plant in all their life
and sampling them is easy. For those reasons, Chrysomelidae is a
suitable object to study the interaction of biomes in the ecosystem.
Nui Chua national park includes the area of semi-driest forest
in Vietnam. Plant communities change in altitude from dry forest on
low land through semi-humid forest green humid forest on a high
mountain. For those reasons, Nui Chua national park is the ideal site to
carry out researching.
For above all reason, I choose the topic “ Study on the
diversity of leaf beetle (Chrysomelidae) and relationship with plant
in environmental condition at Nui Chua national park, Ninh Thuan
province, Vietnam by molecular biological tool ”
