Killing insects brown planthoppers, characteristics of brown planthoppers

Buy black light lamp, but black light is also harmful, the best way is medical ultraviolet lamp, the principle of action is the same as black light lamp, but more effective.

In fact, I have also encountered that they can be driven away by just using a torch, the cost is very low, and they are afraid of heat.

Mosquitoes are afraid of some flowers and volatile smells such as cool oil and wind oil essence, and put one or two pots of blooming roses, mint, Milan, jasmine and other flowers in the bedroom, or put a few boxes of cool oil and wind oil essence with the lid uncovered, and the mosquitoes will be dizzy and then flee. Mosquitoes are also afraid of orange light, so install orange light bulbs indoors in the summer, or put transparent orange paper on the light bulbs, and mosquitoes will stay away.

Mosquito repellent plants mainly include nightshade, lavender, pitcher plant, geranium, seven mile, cordyceps and mosquito repellent grass.

Grate mothballs and sprinkle them in the corners of the house. Plant a tomato or two in a pot indoors, the smell of the tomato branches and leaves will keep mosquitoes away. Hang a handful of chives under the lamp, or put a few green onion segments in a gauze bag, and all kinds of small insects will not fly.

Buy a "black light" which emits ultraviolet rays, and flying insects generally have phototaxis.

Cleaning up their nests may not be a good idea, they are not in your restaurant, but in the outside world

At night, there are many, many small insects flying around under the lights, and this is the most common one"Brown planthoppers"I don't know where it came from, it's terrifying! I just like to be active under the lights, and I die in the morning.

Does this pest have its nest or any pattern? How to prevent it? Is it okay to use pesticides on the Internet?

But how do I safely control pests in a snack shop? What is the safest medicine to use, for people and food! In addition to medicine, what other machines can kill insects, flies and insects!

What is the pest control aspect of the general diet?

Question added: Help! What a black light is simply is"Trapworms"Lamps! How are the traps, there will only be more and more (and everywhere, there is light, there is it)!I don't need it to come in, so why should I tempt it, it's really life-saving? Don't fool me.

What insect repellent electronics don't have right now? What else really works"Insect repellent lights"As long as you can get rid of this"Brown planthoppers"Just don't let it in. Additional points.

Don't use pesticides! That's going to spoil your food! You just need to use Beauveria bassiana, which is OK, and there may be some produce stores for sale!

The only way is to use black lights, the price is not very expensive, and agricultural machinery stores sell it.

Buy a "black light", they don't have nests and are migratory pests.

Buy and kill him and die in the whole house.

I want them all to die. Ha ha.

There are two types of brown planthoppers: long-winged and short-winged. The long-winged body is millimeters long, and the short-winged body is millimeters long. Yellowish-brown, black-brown with an oily luster.

The top of the head is nearly square, the forehead is nearly rectangular, the middle is slightly wider, the antennae are slightly protruding from the basal slit of the frontalium, and the lateral side of the base tarsus of the hindfoot has 2 4 small spines. Forewings yellowish-brown, transparent, wing spots black-brown. The forewings of the short-winged type extend to the 5th and 6th segments of the abdomen, and the hindwings are vestigial.

The male's males have a crab pincer protrusion on the basal side. <

1. There are two types of brown planthoppers: long-winged and short-winged. The long-winged body is millimeters long, and the short-winged body is millimeters long. Yellowish-brown, black-brown with an oily luster.

The top of the head is nearly square, the forehead is nearly rectangular, the middle is slightly wide, the antennae are slightly protruding from the basal slit of the frontal lip, and the hind foot has 2 4 small spines on the outside of the base tarsal town royal joint. Forewings yellowish-brown, transparent, wing spots black-brown. The forewings of the short-winged type extend to the 5th and 6th segments of the abdomen, and the hindwings are vestigial.

The male male's lateral protrusion resembles a crab pincer, and the top is pointed and protruding inwardly and anteriorly; On both sides of the base of the female ovipositor, the basal protrusion of the inner margin of the first lobe is semicircular.

2. When the temperature is high, the oviposition rate of the female adult of the brown planthopper is higher. The peak oviposition period of adult female brown planthoppers lasts 10-15 days, and the peak oviposition period usually lasts 6-10 days. If the temperature is below 17, the ovarian tubes of the brown planthopper will not develop, but these adults will only be kept at a lower temperature for a few hours a day, and after a few days, they will be able to lay eggs at temperatures below 17.

This is a planthopper insect, which may be related to the fact that you turn on the lights at night without closing the curtains, this planthopper has phototaxis, and remember to close the curtains when you turn on the lights at night.

Planthopper (delphacidae) is a planthopper family that is distributed in all provinces of China, and occurs mostly in the middle and lower reaches of the Yangtze River and North China. The host plants are rice, Yingbai, wheat, barley, corn, sorghum, sugarcane, Kanmai Zhaoxiao Niang, barnyard grass and other grasses. Common species are the brown planthopper (Nilaparvata lugens), the white-backed planthopper (Sogatella furcifera) and the gray flyhopper (Laodelphax striatellus).

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: Can clothianidin kill rust ticks:

Clothianidin can kill rust ticks, clothianidin, deltamethrin. Fourth, rust tick rust tick for the damage to the new shoots, leaves, fruits, fruit of sugar orange, after the fruit is harmed, the peel is rough and cracked, commonly known as "black peel fruit", the prevention and control time is 5 September. The specific pests are aphids, psyllids, whiteflies, thrips, leaf miners, weevils, tsubakis, fruit flies, beetle red spiders, rusty ticks, beet nights, jumping beetles and other miscellaneous insects.

Prevention and control of citrus rust ticks: you can choose to use lice mite urea, avi lice mite urea, pyrethoxamide, avermectin, pyridafen, or carbosulfan and other water sprays. Yes, clothianidin can control insect pests mainly green blind bugs, green worms, red and white yellow spiders, rusty ticks, thrips, fruit flies, and one gram of clothianidin is mixed with 1 liter of water.

Ridafen is a broad-spectrum, contact acaricide, which can be used to control multi-plant-eating pests. It has a good effect on the entire growth period of mites, i.e., eggs, young mites, nymphs and adult mites, and it has a good effect on adult mites in the mobile period.

Suggestion: Dear [Xian Hall File Flower] Now that the epidemic is repeated, you must pay attention to the <> of the slag when you go out and pretend to be chaotic

Wear a mask when you go out, wash your hands frequently! Have a great day, <>

<> control of rice planthoppers (late rice) can generally be diluted into 2500-3000 times of liquid with 20-25 grams of 25% thiazinone (Youlede, parachlorine) mixed with water for spraying, and 10% pyridine emulsifiable concentrate (2500-3000 times solution) can be used for spraying for Hekai in elderly larvae; For nymphs and adults with more serious occurrence of Daodan, Zen Chi Zhao can mix thiazinone and 10% pyridon EC before spraying.

The damage to rice is mainly manifested in the following aspects:

Direct sucking: Adults and nymphs swarm at the base of the rice bush and suck the sap of stem and leaf tissues. The insect quantity is large, and when the damage is heavy, it causes the rice plant to be paralyzed and lodging, commonly known as "erosion", resulting in serious yield reduction or harvest loss.

Oviposition damage: During spawning, the stem and leaf tissues of rice plants are stabbed, forming a large number of wounds, which promotes the loss of water from the puncture point to the outside, and at the same time destroys the grooming tissue, aggravating the damage of rice.

Spreading or inducing rice diseases: Brown planthoppers are not only vectors for the transmission of rice virus diseases - grass bush dwarf disease and tooth leaf dwarf disease, but also conducive to the infection of rice sheath blight and sclerotinia sclerotinia disease. The honeydew excreted during feeding is rich in various sugars and amino acids, which is covered on the rice plant, which is very easy to attract the breeding of soot bacteria.

Prevention and control methods:

1. Agricultural control: select insect-resistant (tolerant) rice varieties, carry out scientific fertilizer and water management, bake the field in a timely manner, avoid partial application of nitrogen fertilizer, prevent the growth of rice in the later stage, and create ecological conditions that are not conducive to the breeding and reproduction of brown planthoppers.

2. Biological control: there are many types of parasitic and predatory natural enemies of brown planthoppers in various insect stages, in addition to parasitic wasps, black-shouldered green blind bugs, ladybugs, etc., there are spiders, nematodes, and fungi that have a great inhibitory effect on the occurrence of brown planthoppers, which should be protected and utilized to improve natural control capabilities.

3. Chemical control: according to the type of rice variety and the occurrence of planthoppers, the strategy of controlling the main pest before and after pressure or vigorously treating the main pest generation is adopted, and pesticides with high efficiency, low toxicity and long residual effect period are selected, and the protection of natural enemies is considered as much as possible, and the pesticides are applied at the peak of the 2-3 instar of nymphs.

Main natural enemies: parasitic wasps, black-shouldered green bugs, ladybugs, spiders, nematodes, fungi.

Commonly used agents: pymetrozine, dime and other insecticides. It should be noted that the brown planthopper still has a high resistance to imidacloprid and cannot be used for the control of brown planthopper for the time being.
