Harmful characteristics of Lagerstroemia indica
Nymphs and female adults of Lagerstroemia speciosa mainly gather at the base of main vein of branchlet leaves and suck juice on bud axils, twigs or branches, which often causes the tree to be weak and grow poorly. Moreover, a large amount of honey dew secreted by it will induce severe sooty blotch, which will lead to the blackening of leaves and branchlets and lose their ornamental value. If the insect population density is too high, the branches and leaves will turn black, the leaves will fall early, the flowering will be abnormal, and even the whole plant will die.
