Control of mango longicorn beetles

Longicorn beetles belong to Coleoptera and Cerambycidae, which occur in mango producing areas of southern China. By feeding on the branches with larvae, the growth of the damaged plants is weakened, and in serious cases, the damaged branches are easy to be broken by the wind. The insect produces one generation a year, and it overwinters mainly as larvae, and a few pupae or adults can also overwinter in the pores. From March to April of the following year, the adults began to drill out of the pores, and after mating, the females laid eggs in the gaps of the shoots, the leaf axils of the old leaves or the bifurcations of the branches. The larvae hatched from April to May. After hatching, the larvae drilled into the pith of the branches and ate from top to bottom, opening a hole for ventilation and excretion every 30 cm or so. According to the living habits and damage characteristics of longicorn beetles, the measures for comprehensive control of mango longicorn beetles are as follows: first, cut off and burn the damaged branches when clearing the garden in winter. Second, during the emergence of adults, the use of black light to trap and kill adults, or artificial capture when adults mate. Third, use cotton balls dipped with 80% dichlorvos EC, 40% dimethoate EC 5 times 10 times, plug wormholes, and then seal the holes with clay to kill larvae.
