In summer, the peak of spawning of the beetle and the peak of adult feeding. Although the beetle is small, its damage is huge. Therefore, summer fruit farmers should pay attention to timely prevention and control, to avoid the economic benefits of the farmers.
In the life of the beetle, the larvae of the beetle have the longest survival time in the tree (can reach more than 8 months), and the damage to the fruit trees is also the most serious. Females use a bite to break the bark to form a groove before spawning, and then produce an egg (and many more) in each groove. When the eggs hatch out the larvae, the first-instar larvae feed under the bark. After the age increases, they will penetrate into the xylem. The larvae move in the trunk and open at the bark as a vent hole at a certain distance. Extrapolation of excrement and wood chips.
Physical control
1. Killing adults: For those who have the characteristics of suspended or dry-based habitats, they can be artificially killed or killed directly.
2, eliminate larvae: artificial hammering eggs and peeling bark hooks to kill larvae.
3, the trunk is painted white: 1.5-2 meters from the ground, the trunk is painted white to prevent the beetle from laying eggs. If there are cuts and kerfs on the fruit trees, apply protective agents (varnish, etc.) in time to prevent the beetles from laying eggs.
4, lure trapping: For some of the beetle (such as: peach red neck beetle) adults have a tendency to sweet and sour, can manually prepare sweet and sour wine (sugar: vinegar: wine is 1:0.5:1.5), and add insecticide Agents (such as: trichlorfon, etc.) to lure.
Biological control
The beetle has many predatory and parasitic natural enemies, one of which is the swollen leg bee. The swollen leg bee can find the larvae and pupa of the larvae along the worm tract and lay eggs in the larvae or larvae of the beetle. After hatching, the swollen leg bees suck the nutrients of the larvae and cockroaches, causing their death and achieving the control effect. In addition to swollen leg bees, there are also velvet armor, Beauveria bassiana and parasitic nematodes, which are currently commercialized and can be applied.
Chemical control
1. Adult control: In the peak period of larval emergence (from June to July in adult popula), use pyrethroids, chlorpyrifos, imidacloprid and other agents for control, spray the garden for 5-7 days, and spray the main parts. The cadres are mainly used, and each time they spray, the liquid flows along the trunk to the roots; or it is dried with the above-mentioned agents.
2, eggs and young larvae prevention and control: Tianniu spawning and young larvae activities are under the epidermis of fruit trees, not harmful to the xylem, at this time should pay attention to let the larvae or eggs under the bark contact the agent, kill eggs and young larvae.
In the period of oviposition and larval hatching (the peak of spawning is generally from June to July), find the oviposition groove and larvae damage (check the tree table wound, pupil), apply medicinal application, poison cotton dressing, poison Three methods of soil adhesion are used for prevention and treatment.
3, medicinal application: use pyrethroids, organic phosphorus and other insecticides plus diesel or diesel for application;
4, poisoned cotton dressing: the liquid is sucked in the cotton wrapped on the branch (scratch the old skin), and then wrapped with plastic film;
5, toxic soil sticky: the liquid is mixed with a suitable amount of clay into a medicinal soil, adhered to the oviposition and larvae damage.
6. Prevention and control of larvae in the tunnel: The larvae entering the xylem are harmful, and prevention and control is more difficult. First find the new defecating mites (after the heavy rain, the trunk and the manure under the tree have been washed away, and the fresh septic hole is easy to identify). If there are multiple drainage holes, the last hole should be selected. Firstly, the manure should be dug, and the medicine should be inserted into or injected into the tunnel (optional mothballs, gasoline, cotton coated with drugs, etc.), then wet clay or wet yellow. The mud seals the hole tightly, and the effect is checked after 7 to 10 days. If there is new manure, the hole should be rectified.

ynephrine (or oxedrine) is a drug commonly used for weight loss. While its effectiveness is widely debated, synephrine has gained significant popularity as an alternative to, a related substance which has been made illegal or restricted in many countries due to health risks and its use as a precursor in the illicit manufacturing.
There is however no occurrence of diverted synephrine for the manufacture of amphetamines, and the naturally occurring synephrine is, due to its phenolic group, unsuitable for such diversion.
Products containing bitter orange or synephrine are suspected of causing adverse cardiovascular reactions. Synephrine is derived primarily from the immature fruit of Citrus aurantium, a relatively small citrus tree, of which several of its more common names include Bitter Orange, Sour Orange, and Zhi shi. Dietary supplements generally supply single oral doses of 3–30 mg, while as a pharmaceutical agent it is given orally or by parenteral injection in 20–100 mg doses as a vasoconstrictor to hypotensive patients.
