A Detailed Guide to the Occurrence Characteristics and Control Techniques of the Tea Black Spiny Whitefly
The black spiny whitefly mainly feeds on tea plant sap from the undersides of leaves as larvae and excretes honeydew, which attracts sooty mold fungi and induces sooty mold disease; in severe cases, the tea plants turn pitch black. Affected tea plants have reduced photosynthetic efficiency, lower sprouting density, delayed sprouting, thin and weak buds and leaves, and severe leaf drop, which not only affects tea yield and quality but also seriously affects the vigor of the tea plants. I. Occurrence Characteristics This pest has 4 generations per year, overwintering as mature larvae on the undersides of tea leaves, pupating in March of the following year; the peak periods of the 1st to 4th generation larvae are in late May, mid-July, late August, and late September to early October, respectively.
