Entering Futian, garden diseases and insect pests have also reached a peak period, and some of the cicada hazards in the stinging pests have to be careful!
【1】Leafhopper:
1. Identification characteristics: leafhopper body length 3-15 mm, 2 single eyes, a few species without single eye. The posterior tibial segment has a ridge with 3-4 rows of spiny hairs on the ridge, and the terrestrial terrestrial terrestrium of the posterior foot is a prominent identifying feature of the leafhopper family.
2. Hazard characteristics of leafhoppers:
Both adults and nymphs feed on the sap of the plant. After the leaf is damaged, there are white spots that lose their green, and the latter points are connected into pieces until the whole leaf is pale and dead; some cause scorched spots and plaques, so that the leaves fall off prematurely. In addition, leafhoppers can transmit viral diseases in addition to direct harm.

【2】Spotted wax cicada:
1. Identification characteristics:
Small nymphs: black on the body with many small white dots on it; older nymphs have black and white markings on their reddish bodies; and adults have red at the base of their hindwings and are brightly colored when flying.
2. Hazard characteristics of spotted wax cicada:
Adult insects and nymphs cluster on the back of the leaves and young shoots suck the damage, causing coal pollution disease or atrophy and deformity of the young shoots of the affected plants, which seriously affects the growth and development of the plants.
【3】Broad-winged wax cicada:
Adult: Transparent and milky white at the beginning of the feather, after about half a day, the body color changes to an inherent yellowish brown. The wings are densely covered with a web of longitudinal veins, the forewings are broad and slightly triangular, and the hindwings are pale yellowish brown and translucent.
Nymphs: the body shape is slightly blunt diamond-shaped, the body color is dark yellowish brown, the cloth has different shades of markings, the body is sparsely covered with white wax powder, and there is a white fluffy wax filament at the end of the abdomen, which is round and fan-shaped, and sometimes it is also peacock-shaped.
2. Hazard characteristics: adult insects and nymphs suck sap on young branches, shoots and leaf backs. After the plant is damaged, the leaves shrink and the branches wither and break, forming dead shoots. In severe cases, the branches, stems and leaves are covered with white wax, and the excrement can induce coal pollution.
【4】Pine cicada:
Adults: The head protrudes forward, the central part is black-brown, the sides are yellowish brown, the wings are grayish brown, the base and middle of the broad transverse band and the outer stripes are brown.
Nymphs: 1st instar nymphs have black or blackish brown heads and thoraxes and red abdomen; the bodies of late nymphs are blackish brown or yellowish brown, and the antennae are bristle-like.
2. Typical hazard characteristics:
(1) Nymph period hazard: Pine cicada nymph endangers the basal tissue of pine tree young shoots, and the tail is constantly swinging when sucking sap, and white foam is discharged from the abdomen to cover the insect body, so it is commonly known as "blowing bubble worm".
(2) Adult stage hazards: After the adult insect feathers, it is necessary to supplement nutrition for a long time, suck the sap at the base of the young shoots, disperse the damage, and no longer discharge foam.
【5】Comprehensive prevention and control methods:
When the harm of sucking insects and cicadas is found, measures can be taken in time to carry out rapid and efficient prevention and control such as Qilin Guangzheng or Qifa spraying.
