Scientific name Apripona germari (Hope) Coleoptera, Cerambycidae. Alias ​​shoulder Tianniu, Sanggan black Tianniu, Sangniu, and so on. Located in Central China, East China, South China, Southwest China, North China, and Northeast China. The host is mainly responsible for harming mulberry, but also harms apples, pears, betel nuts, jellyfish, mountain sandals, plums, cherries, oranges, figs, oysters and so on. Injurious characteristics: adult larvae harm the twigs and leaves; larvae in the subcutaneous and xylem of the branches, foraging downwards, there is no dung in the tunnel, and the dung is evacuated at a certain distance from the outside. Tree vigor, heavy dead. Life habits 2-3 years north l, Guangdong l years l; larvae in the branches of winter, the host began to infestation after germination, dormant overwintering when fallen leaves. The northern larvae matured between June and July after two or three winters, and wood chips were built on both ends of the tunnel. Fifteen to 25 days. After eclosion, 5-7 days after stopping in the larvae, biting feather holes were drilled, and adult animals emerged from July to August. Adults feed more at night and start to spawn sooner or later, and spawning takes about 10-15 days. The 2-4 years old branches lay more eggs, multiple selections of the middle or base of the branches with a diameter of 10-15mm, first bite the skin into "U" shaped wounds, then spawn in them, each producing 1 egg, occasionally 4-5 tablets. Each female can produce 100-150 eggs, spawning about 40 days. The egg period is 10-15 days. After hatching, between the phloem and the xylem, it feeds about 1 cm above the shoots, and then enters the xylem and feeds downward. If it is slightly larger, it will enter the pith. Beginning every 5-6cm length of the excrement hole, the distance from the defecation hole increases with the growth of the body, the small larvae excrement red-brown cord, the excrement of the big larvae is sawdust. The larvae lived in tunnels for up to 2m and there was no excrement and sawdust in the tunnel. Prevention methods (1) Mulberry trees are best not grown near Mulberry to reduce the source of insects. (2) Combine pruning to remove the larvae and focus on the treatment. (3) In the adult stage, adults are killed in time and eliminated before spawning. (4) Combining adult pest control with other pests, spraying 40% dimethoate 500 times liquid, spraying on the branches. (5) Adult egg digging and early instar larvae after spawning. (6) Assassinate larvae in the xylem, find fresh defecation holes and insert them with thin wire, pierce down to the tunnel end, and repeatedly puncture the larvae. (7) The early larvae of the poisonous larvae can be used 10-20 times liquids such as dichlorvos or azadirachtin to kill eggs. The larvae that enter the xylem can be injected with liquid medicine from fresh defecation holes, such as 50% phoxim EC 10 to 20 times, or the above-mentioned agents, with a maximum of 10 ml per well, and then sealed with wet mud to kill the insect effectively. (8) Try the long-acting inhalation dry agent, available YBZ-B type trunk injection machine, injection of long-acting injection dry agent, can also be used in the diameter of 4 - 5mm steel nail 50 to 80cm away from the ground obliquely Hole, deep 3-4cm, and then use rubber dropper or veterinary syringe injection injection agent. The calculation of the drug dosage temporarily used the forest tree calculation method, that is, the first measurement of trunk diameter, and then convert or detect the diameter, injection dose of 0.5ml per cm diameter, mulberry diameter of 10cm or more, should be appropriate to increase the dose through the test. In addition to effective control of natural calf, this method can also treat other stem pests and scale insects, aphids and so on.

Antennae filamentous, 11 knots, 1st and 2nd black, the rest of the knots half dark brown, base half gray. There are irregular transverse wrinkles or transverse ridges between the front and back transverse grooves of the prosthodontic plate, and the lateral spikes are thick. The base of the elytra wing is covered with bright black granular protrusions, accounting for about 1/4 to 1/3 of the full wing length; the inner and outer corners of the wing tip are stippled. The egg is long and oval, 6-7 mm long, slightly flat and curved, and the colostrum turns pale brown. The larvae have a body length of 60-80mm, cylindrical and milky white. The head is tan, and most of it is in the chest. The 13th section of the service section is not full, the first section is slightly square, the back is densely covered with khaki bristles, the latter half is dense with auburn grainy dots and has a “small†shaped indentation; 3—10 sections of back and belly are flat Round step bubble, dense russet particles. Clam 30-50mm long, spindle-shaped, yellowish-brown after the first pale yellow, wing buds up to the third abdominal section, the end of round bristles.
