The insects, also known as the mesozoans, are small insects that live in a codificous order of pests, oval, linear or oyster-shaped. Common ones are grasshopper, yasuk-tip bug, blowing sponge bug, camphor clam round shield bug, bran flake bug, Korean ball nymph, mulberry white borer, Kang's pink bug and so on.
The larvae have short legs, the larvae are mobile foraging, and the slightly longer ones have degenerated feet and are dioecious. Females are wingless, and males have 1 pair of membranous forewings, which are specialized as balance rods. Its reproductive ability is strong, occurring 2 to 3 generations a year, the eggs hatch into nymphs, after a short period of crawling, camp fixed life, that is, the formation of insect shells.
For many years, the insect shell insects have been flooded in large areas of pepper gardens, orchards, persimmon gardens and jujube gardens, and caused huge losses due to the ineffective control of some fruit farmers. It prefers to eat sap, and the density of insect mouth is large, which harms the leaves, branches and fruits, causing the leaves to turn yellow, the branches to wither, and the tree to decline. The insect also has a secretion, which often causes a white membrane in the affected area, causing water and nutrient shortages, resulting in the death of fruit tree stems. In addition, the secretions of the insects can also cause soot disease, causing economic losses.
The summer heat and humidity of the insect shell are the most serious pests in late May and early June. The main difficulty in the control of insects is that it has a relatively hard shell, a thick wax layer, strong resistance to drugs, and it is difficult for general agents to enter the body, and it is more difficult to control. Therefore, once it occurs, it is not easy to remove clean.
For a long time, farmers have used phosphorus killing to control insect shell insects. Phosphorus killing is broad-spectrum, fast-acting, especially in the control of insect shell insects is very effective, and the price is affordable, widely used in orchards, vegetables and other crops. However, due to its high toxicity, in 2015 the Ministry of Agriculture revoked the registration of phosphorus killing in citrus trees and other crops such as vegetables, melons and fruits. After the ban on phosphorus killing, there are few drugs in the market to effectively control insect shell insects.
At present, the active ingredients commonly used in the control of ticks on the market mainly include ethyl spirospirene, thiazide ketone, and chlorpyrifos. Due to the waxy shell of the insect, the best agent is a highly permeable and absorbent variety, such as ethyl spironium. Generally in the north of April-May, south of 3-4 months, mesozoan eggs began to hatch, the use of contact insecticides during the peak period of egg hatching effect is also better, imidacloprid has systemicity, chlorpyrifos has a better fumigation effect, so the above drugs in the control of mesozoans have a better effect. In addition, zoloftamide also has a good control effect.
Shell insects have a relatively heavy occurrence in the domestic Jiangxi and southern Fujian markets, and are concentrated in various types of fruit trees and other cash crops. Although its control market has declined due to the decline in the number of elderly fruit trees, the ban on the highly toxic pesticide phosphorus has brought opportunities for micro-toxic insect control products. Therefore, the domestic scale control market has certain development potential.
At present, the main drugs registered by multinational companies in ICANA for the control of ticks are as follows:

In terms of use cost, the cost of ethyl spiranter and chlorpyrifos is higher. Therefore, for farmers, both in terms of the cost of control and the ease of use, it is of great significance to develop new insect control products.
The number of shell control products developed by domestic enterprises is not large, including the latest new products of Xinnong, Mingde Rieter and other companies. Here I will briefly introduce several products that I have learned. (Click on the title and image for product details)
Zhejiang Xinnong - Xinnongwei ®
Xinnongwei ® (8% ethyl spirant ester + chlorpyrifos 32%) is a new patented insecticide jointly developed by Xinnong and Bayer of Germany, which has special effects on sucking mouthpiece pests such as ticks and wood lice. Xinnongwei ® has good lipophilicity, so it is easy to bind with the waxy layer on the surface of plant leaves and the surface of the pest, and the agent can quickly reach the target pest. The results of the previous field experiment showed that Xinnongwei had a good effect on citrus red wax beetle, and the efficacy and efficacy of red wax beetle at a test dose of 1000 times was comparable to that of 4000 times the dose of Muwante, and the efficacy was good and the efficacy period was long, and there was still a high efficacy after 49 days of medication.
Mindridt – Delang ®
The active ingredient of Delang ® is 15% spironoid ethyl ester and avermectin, which has good quick efficacy and a long duration of efficacy, and the duration of validity is generally more than 25 days. After the ethyl spirant in Drang ® is absorbed by the leaves, it can be conducted through the xylem to the top of the plant, and at the same time, it can also be transmitted to the plant base through the phloem, and the internal conductivity is strong, and the liquid is transported to the hard-to-reach parts through two-way conduction, which can kill hidden pests, new leaves and root pests. Avermectin also has very good systemicity, coupled with Mindridt's innovative hypertonic preparation technology, which has a good control effect on hidden and shelled pests such as ticks, pear lice, thrips, and jumping nails.
Kesheng Group - Bao Sheng ®
Baosheng ® is a high-content environmentally friendly insecticide developed by Kesheng Group, which is made of the best ratio of two different mechanism insecticides, with obvious synergistic effect, with touch killing, gastric toxicity and fumigation effect, mainly used to control a variety of aphids, aphids and a variety of overeating, leaf curling, and drilling moth pests, especially suitable for fruit trees. Baosheng ® contains fluorine elements, strong affinity, resistance to rain erosion, and stable insecticidal activity.
Hellier – double product ®
The double product ® is 25% chlorpyrifosine microcapsulant suspension, of which chlorpyrifos content is 20%, using the highest encapsulation rate of microcapsules, with superior spontaneous dispersion, the agent directly hits the tick target, slow release, more long-term effect. 5% imidacloprid is steadily suspended around the microcapsule and acts faster. The double product adopts ® Otis special shell breaking additive, which has a good killing effect on red wax borer, bran flake bug, black spot bug, brown round bug, ball bug, arrow tip bug, sponge powder bug, blowing sponge bug, turtle wax bug, white shield bug and other shell insects. At the same time, it is still suitable for all kinds of insects of various seedlings, flowers, fruit trees and other plants, and the prevention effect is remarkable.
Lil Chemical - Ke Huan ®
Lier Chemical Kehuan ® (acetium 1.5% + poison cicada 40%) is a product with good control effect, the insecticidal mechanism of the two active ingredients is different, and the acetamidine compounded with the poisoned cicada is a nicotinic super efficient new insecticide, which has strong gastric toxicity and touch killing for pests, and also has a strong systemic and strong osmotic effect, so it can stably exert its strong quick-acting and more than 20 days of effectiveness. It is highly effective against sucking mouthparts pests (aphids, aphids, planthoppers).
Xin'an Chemical - Acetone Chlorpyrifos
Chlorpyrifos anthropris chlorpyrifosus is a pesticide mixture of organophosphorus and pyridine, and after the delisting of phosphorus, it is an important substitute for the control of ticks in orchards. It has a touch killing, gastric poisoning and certain fumigation and osmosis effects, and can effectively control citrus tree aphids and mesophores.
