The longhorn beetles are distributed globally from sea level to mountain sites as high as 4,200 m altitude wherever their host floras are available. All the members of the family Cerambycidae are either phytophagous or xylophagous. Many species are important pests of forests, plantations, fruit and street trees. Usually, the adults are known to girdle twigs or branches to feed on foliage or blossoms. The longhorn beetles inflict damage to plants by feeding internally the heart wood or sapwood and sometimes acting as root borers or gall formers. In recent times extensive cultivation of crop combined with greenhouse effect causes many longhorn beetles to become serious pests in horticulture ecosystem. Mainly the plantations and fruit crops are threatened by longhorn beetle which results in reduced vigour and complete death of plants.
