A few species are harmful to flowers, grain storage, fruit storage, silkworms and fresh insect specimens, and some species are ectoparasites of bats and rats. Leatheroptera generally prefer to be nocturnal, and often hide under soil, stones, dead branches, and garbage during the day.

It looks like a poisonous insect, and I've seen it in the vegetable field before...Shiver. Clean it and spray it, it won't necessarily bite you, hehe, it's okay

<>Cockroach] is an insect belonging to the order Leatheroptera, with a body length of 4-35 mm. The body is elongated and narrow, slightly flattened. The head is flat and broad, the antennae are filamentous, there is no single eye, and the mouthparts are chewing.

The dorsal plate of the anterior thorax is well developed, square or oblong. The body surface is leathery and shiny. Winged or wingless.

If there are wings, the forewings are specialized into very small leather wings; The hind acres are large, membranous, fan-shaped or slightly rounded, folded vertically and horizontally under the forewings at rest, but often exposed outside the forewings. The tail whiskers are in the shape of a stump. There is no ovipositor.

Cockroaches are mostly omnivorous or carnivorous species, most of them live in the cracks of bark, in decaying wood or under fallen leaves, and like damp and dark sex, many species are accustomed to nocturnal walking, and have the habit of phototropic flight.

Diet: omnivorous, eats everything, generally found in bathrooms and kitchens.

Prevention: Keep the house dry, especially the bathroom to keep it clean, you can buy a bottle of aerosol insecticide, and just open the draft when you see it!

Grub control methods:

The occurrence in the pot is generally due to the application of organic fertilizer such as horse manure, or because there are insect eggs in the potting soil, so it is necessary to pay attention to check and eliminate when changing the pot;

After the grubs are found in the flowers planted on the land, the soil should be turned over once in autumn to kill the overwintering grubs;

When applying organic fertilizer, it is necessary to kill insects first, spray 80 dichlorvos 500 800 times liquid on the manure and mix well, and then seal it for 24 hours;

Watering the soil or potting soil with 50{bf} of malathion 800 1000 times, or 25 octathion 1000 times solution, can kill pests;

Take the leaves of Arborvitae orientalis or castor beans to dry, grind them into powder, and mix them into the soil to also have a control effect;

When grubs occur on the lawn, 80 dichlorvos 1000 times liquid mixed with 40 dimethoate 2000 times liquid can be watered, and the control effect is remarkable.

The prevention and control of underground pests and grubs should be based on comprehensive control, select appropriate pesticides and application methods, and grasp the timing to control adults and larvae at the same time, so that the grub population can be controlled below the harmful level.

1. Physical control: Using the characteristics of adult phototaxis and chemotaxis, black lights and sexual attractants can be used to trap and kill adult grubs (beetles). Mid-June to late July is the peak period for adult worms, which is the peak season for sweet potato growth, and black lights can be installed in sweet potato fields to trap and kill adult insects.

2. Agricultural prevention and control: mainly combined with farming measures to control grubs. Potato-wheat rotation is often practiced in the northern potato area, which can be dried in the soil after the wheat harvest in early June, and the chickens can be artificially killed or raised to peck at the larvae.

In October, the summer potatoes are harvested at the same time to complete the deep ploughing of the land, which destroys the living environment of the grub in the soil, and the grub can use irrigation to eliminate the larvae by using the characteristics of the grub to be afraid of flooding.

3. Biological control: At present, the most widely used and most effective is the use of Beauveria bassiana, Metarhizium aeruginosa and other fungal preparations to control grubs, especially Beauveria bassiana in the sweet potato field to control grubs is very successful. After the application of Beauveria bassiana at the planting stage, the tuber swelling stage or the peak larval stage, the spores infected the grub larvae and made them lethal, and the fungus soil still had a certain control effect after three years of application.

This method has the advantages of low resistance to pesticides, less residue and high pathogenicity, and has broad application prospects.

4. Chemical control: This method has the advantages of fast effect, good control effect, economy and practicality, and can be used or nine net.

Answer: Prevention and control methods of grubs: (1) Agricultural control. Implement water-drought rotation and do not apply unripe organic fertilizer; When harvesting peanuts in autumn, plough and pick up grubs, or let ducks, chickens, and geese hunt for food.

2) Trapping adult insects. When the adult worm is in full bloom, it can be trapped with a black light. In the black velvet tortoise shell flourishing area, 30 40 cm of fresh elm, poplar and black locust branches can be immersed in 30 40 times of 40% oxidized dimethoate, and they can be taken out and inserted into the peanut field in the evening, and 210 20 branches per 667 meters can be booby-trapped.

3) Pharmaceutical prevention and control. 50% phosphine seed dressing with seed weight, or seed coating agent with 2% seed weight can be well controlled from grubs. When sowing, mix 10 15 kg of fine dry soil with 3% carbofuran kg or 5% kg of phoxanthion granules every 667 m2 and sprinkle evenly in the sowing furrow (do not contact with seeds).

In the peanut growing season, spray 40% dimethoate oxide in the peanut field, spray 30 40 kg of water with 50 grams per 667 m2 to kill adults and reduce leaf eating. Every 667 m2 with 50% methyl isosulfonate 250 300 grams, or 5% phosphine granules kilogram mixed with fine dry soil 15 20 kg sprinkled on the roots of peanuts, combined with soil to kill hatched grubs, can also be methyl isosulfonphos emulsifiable concentrate into 600 times the solution of the root irrigation.

Grub is a common name for beetle larvae. The main species of grubs that occur in farmland in China are the golden beetle with dark gill beetle, golden beetle and golden beetle with great black gill.

The following measures can be taken to control grubs:

1) Agricultural control: the implementation of autumn ploughing to reduce the base of insect sources.

2) Chemical control:

Seed treatment. You can use seed coating agent or use agent to dress seeds and stuff seeds. The general seed-to-drug ratio is about 40 1;For every 600 1000 kg of soybean seeds, 1 kg of 50% phosphine fibre concentrate, first stir the agent with 100 kg of water, mix well with the seeds, and stuff for 12 24 hours.

Soil treatment. Pesticides can be evenly sprinkled or sprayed on the ground, and then ploughed into the soil, or pesticides can be mixed with manure and fertilizer, granules can also be mixed with seeds, and covered with poisonous soil, strip application, furrow application or hole application.

3) Biological control: the application of biological agents such as epilepsy and Beauveria ovosporus, the dosage of emulsion bacteria is kilogram of bacterial powder per mu, and the dosage of Beauveria ovosporum is spores per square meter, and the effect can last for more than 1 year.

(1) Agricultural prevention and control.

Deep ploughing of vegetable fields in late autumn can turn the adults and larvae to the surface of the ground, so that they can freeze to death, dry or be preyed on by natural enemies, mechanical killing, etc., and can eliminate some of the overwintering larvae and adults; Apply fully decomposed organic fertilizer, cover with plastic film, compost, kill pests in fertilizer at high temperature, and avoid applying unrotted organic fertilizer, so as not to attract adult eggs and reduce the introduction of larvae into vegetable fields; Water and drought rotation can be carried out in areas where conditions permit.

2) Artificial killing.

Sieve and pick out the grubs in the organic fertilizer before fertilization; In the peak stage of adult insects, the feign death and phototaxis of beetles are used to manually capture, shock and kill, or trap with insecticidal lamps.

3) Chemical control.

Seed dressing: 25 ml of 40% phosphine EC, 1 liter of water, and kg of seeds. Toxic soil: 100 ml of 40% phosphine emulsifiable concentrate per mu is added to the liter of water, mixed with 20 kg of sieved fine dry soil, mixed and applied.
