Prevalence: fujian and guangdong, guangxi year happen one generation, with sexual immature adult winter. Over-wintering stage adults in a cluster sex, shelter, host and a dense canopy xiangyang, also have foliage wintering in orchard houses near house page tiles inside. Following early march when the temperature reaches around 16, wintering in little adult began activities litchi and longan branch top or flowers, stay in the ear began after feeding maturity JiaoWei laying eggs, eggs from leaves more back. Besides, there are also a few its eggs on the branch top, trunk and tree body other than the place. The fecundity period since mid-march until early October 4, 5 months, for spawning stage,

Pop dynamic:

Prevention and treatment: elixir prevention: march in new shoots overwintering adults between the JiaoWei poles once, when activities to 4, 5 months young larva happen again stage spray 1 to 2 times, jet between 800 ~ 1000 times liquid effect very good, or with 20% kill chrysanthemum ester 2000 ~ 80 times liquid. Average amount of liquids bunches of spray, large area 7.5 a 10 kilograms, litchi and longan region of the pesticide used aircraft 20 times liquid, (between 30-37.5 kilograms per hectare) o

Biological control: (in a parasitic enemies libo eggs smooth abdomens small bee (Anastatus sp.), li (Ooencyrtuscorbetti eggs jumped small bee (Ferr.), the Malay yellow abdomen eggs O.m alayensis Ferr little bee (j) and yellow foot small bee (O.c rionotoeFeff.), and li (bacteria, mantis, birds, should be protected and utilization, use smooth abdomens little bee prevention, in guangdong lychee (already popularized, fujian has also experimental demonstration, in early spring into or reproductive accumulation plenty of smooth abdomens little bee, libo spawn in the beginning (put bees every 10 days, and then put a, a total of three times, general each put puts 500 head piece (female, when lychee density, and choose between liquid injection, down population density, followed after put drones.

Artificially killed. LuanKuai overwintering emigrated, picking hunted and extinguish nymphs.

First, the elimination of adult. Winter 10 ℃ low-temperature period, wintering under less activity, with adult with hook bamboo branches, make adult fierce wave DuoDe, centralized destroyed except in the tree, but adult winter, this method not only is auxiliary measures.

Second, picking LuanKuai. 3 ~ 5 months (LuanKuai libo spawn stage, picking the effect of centralized put people in simple, protect the natural protector.

Third, extinguish nymphs. Dip in with bamboo poles pierced with cow urine and grass, or human urine beaten worm body fluids, bad or heave tied with rag ball dipped in bamboo larva, kerosene, smoked fell in tree in advance of sand or pile head fine earth mix plant ash, make the corruption of the nymphs not easy on the tree, hunts.
