Now it is not easy to think, now not only those friends who like passion fruit hate the small bugs on passion fruit, but even the friends who grow passion fruit are trying to deal with them, just for one purpose:
Eliminate bugs, incremental quality improvement! Let friends who want to eat passion fruit realize "passion fruit freedom"!
Now, I have deliberately sorted out the harmful symptoms and control methods of some common insect pests on passion fruit, hoping to help everyone!
<h1>aphids</h1>
Hazard mode:
Aphids are a pest of sucking mouthparts, often clustered in the young leaves, new shoots, buds, top buds and other young tissues of passion fruit, and like to eat "tender grass".
It is destroyed by sucking the sap on the young leaves of the new shoots, resulting in curling, shrinking, shortening between nodes, not being able to stretch normally, almost stopping growth, and wilting in particularly severe cases, causing young fruits to fall off and a large number of new shoots to be unable to be extracted, resulting in a decrease in yield in the current year.
The "honeydew" excreted by aphids, the main cause of soot disease, affects leaf photosynthesis.
It can also cause passion fruit leaves to curl and harden.
It is also one of the main vectors for the transmission of viral diseases.
Prevention and control methods:
1. Physical prevention and control: yellow plate booby trap;
2. Pharmaceutical control: avermectin + chlorofluoridine/ furazine / bromocyanobiacidine, thiamethoxam + high efficiency cyfluthrin, leaf spray.
Aphid infestation
<h1>Thrips </h1>
The thrips, which are not horses, are a pest that is difficult to detect with the naked eye.
Thrips use adults and nymphs to file the sap of young tissues (branches, leaves, flowers, fruits, etc.), and the young leaves and shoots of the victims become hard and rolled
The curve wilts, the plant grows slowly, the internodes shorten, and the young fruits will be lignified after being killed, causing fruit drop in severe cases, which seriously affects the yield and quality.
More seriously, passion fruit thrips are one of the main members of this passion fruit infection virus disease.
Prevention and control methods:
1. Physical prevention: rebound booby trap;
2. Pharmaceutical control: avermectin + chlorofluoridine amidine / furazine / bromocyanocyanate, thiamethoxam + high efficiency cyfluthrin.
Thrips hazards
<h1>Bugs</h1>
Like thrips and aphids, bugs are sucking mouthpart pests.
It mainly sucks the sap of buds, petals, leaves, young leaves and fruits through its sucking mouthpiece, causing falling flowers, leaves, flowers and fruits, affecting the tree potential and fruit commodity.
High efficiency cypermethrin, perchloride flulingurea.
<h1>Fruit fly</h1>
Fruit fly harm way, in it harms many melon fruits, is the adult worm laying eggs in the passion fruit fruit, we can see the passion fruit peel surface uplift, after the eggs hatched after the larvae, mainly eat passion fruit pulp, destroy its tissue, so that the victim fruit shrinks, yellow, rotten, serious damage to the "value" of passion fruit, reduce the value of passion fruit commodities.
In the later stage of the hazard, the passion fruit stalk produces a separation layer, resulting in the "premature aging" of the passion fruit falling off in advance.
After the fruit fly larvae fall to the ground with the affected passion fruit, the mature larvae of the fruit fly can penetrate the peel and enter the soil to pupate, continue to "repeat the story of yesterday", and repeatedly endanger the passion fruit.
1. Pranayama before feathering, spraying, can choose avermectin, high-efficiency cypermethrin, chlorpyrifloride;
2. After the fruit fly feathers into adult worms, high-efficiency cyfluthrin can be selected for culling;
3. In general, fruit flies move quickly, relying on physical control for booby traps, such as yellow boards, rebounds, booby trap balls, booby traps, the effect is still quite obvious.
<h1>Whitefly</h1>
Adult and nymphs of whiteflies can suck up the sap of the phloem of plants. Because of its rapid development and high fecundity, often the population can reach a very high density in a short period of time, thereby absorbing a large amount of sap, resulting in plant weakness; adults, nymphs secrete honeydew and waxy substances to pollute plant organs and fruits, induce the occurrence of soot disease, hinder plant photosynthesis, resulting in leaf atrophy, wilting and early leaf fall, while reducing the quality and quality of crops; some whiteflies are important vectors for many viral diseases, and the plant viruses transmitted can lead to plant malformations and fruit failure, causing serious losses.
Avermectin + chlorfluoridine amidine / furazine / bromocyanobiaciline, thiamethoxam + high efficiency cypermethrin
<h1>cockchafer </h1>
Scarab beetle larvae, also known as grubs. It is a major underground pest that feeds on plant roots and tubers or seedlings.
The scarab beetle, on the other hand, is harmful to the aboveground parts of plants such as leaves, flowers, buds and fruits.
Adult leaves are reticulated with holes and missing notches, leaving only the main vein in severe cases and more severe in clusters. It is often best served from late afternoon to 10 p.m.
1, physical booby-trapping, using its phototropism, hanging black lights in the orchard, booby-trapping;
2. In order to kill the larvae of the scarab beetle, that is, grubs, you can choose furoxamin, thiamethoxam and other agents for root irrigation;
3. If you want to spray and kill scarab beetles, choose beetle mite cyanide, high-efficiency cypermethrin, high-chlorine • flubellurea, etc., to deal with it is more than enough.
<h1>Insects</h1>
After female adults and nymphs pierce their mouthparts into branches, fruits and leaves, they begin to suck up sap and live a fixed life ever since, depriving the host plant of nutrients and losing a lot of water.
The affected leaves often show yellow spots that fall off early later.
After the young shoots and young shoots are damaged, poor growth often leads to yellowing and wilting.
In severe cases, the insects will overlap densely, the development of the affected plant will be hindered, the tree will weaken, and even the branches or whole plants will die.
While harming crops, the insects will also excrete a large amount of honeydew, which will lead to bituminous coal disease and make the leaves unable to photosynthesis; The severely damaged plants, the tree declines, and finally the whole plant dies.
Chlorpyrifos perchlorine, ethyl helix + silicone, leaf spray.
<h1>Kowtow</h1>
Kowtows are small to medium-sized insects , mostly grey, brown or brown. Its larvae are commonly known as golden needle worms, with slender bodies, smooth and tough body walls, particularly hard heads and stubs, and mostly feed on the underground parts of plants, which are important underground pests. Kowtow nails also have greater harm to passion fruit flower utensils. It usually bites the flower seat at night to eat honey juice, causing damage to the flower vessel and easily causing the flowers to fall.
1. Physical booby-trapping, black light lamp, straw bale pole;
2. Kill larvae (golden needle worm), furazine, thiamethoxam, irrigation roots;
3. Spraying adult insects (kowtow nails), high efficiency cypermethrin, high chlorine • flulingurea.
<h1>Coffee leopard-grain wood beetle moth</h1>
The coffee leopard wood beetle moth is a larval moth that feeds on the xylem of the branches, bites outward at a certain distance into a fecal hole, and mostly feeds upward along the marrow, causing broken branches or wilting, which is more harmful to the tree.
Adults lay their eggs on young branches, and the larvae begin to moth into the shoots after hatching, and when they moth downwards, they can reach the base of the trunk, and often turn back to moth other branches.
When it transfers branches to harm, it is mostly mothed from the main trunk about lcm in diameter.
Each larvae can often moth 1 branch, but there are also sporadic branches.
Adult worms live 5 to 7 days.
1. Using phototropism, hanging black lights for booby-trapping;
2. Wire puncture: use a thin wire to insert it from the borer hole or fecal hole to repeatedly puncture upwards, and the larvae can be stabbed to death;
3. Cut off the injured branches in time, burn them centrally or bury them deeply, and control them after 1 to 2 years;
4. Pharmaceutical control, when adult insects are feathered, beetle mite cyanide, high efficiency cypermethrin, high chlorine • flulingurea spray, when the worm hole is found, cotton is dipped in wet furazine, thiamethoxine, propyl bromophos and other medicinal solutions to block the worm hole.
<h1>snail</h1>
Snails use young shells and adult shells to scrape passion fruit leaves, stems, flowers or bite off seedlings with their teeth and tongues.
In orchards with high groundwater levels and humidity, snails can often cause serious harm.
Snails harm the crop seedling stage, which causes damage to leaves and stems, late occurrence of zombie seedlings, and a decline in the seedling formation rate; heavy seedlings are all eaten up, resulting in no seedlings; in other periods, snails are harmful to leaves, plant branches, and fruits, and the leaves are harmed, resulting in insufficient photosynthesis and weak tree strength.
Endangering the branches of passion fruit can reduce the transport capacity of the phloem, but also the spreader of germs (many snails are often gathered in the scars of rot disease, and after dispersion, they crawl around to spread the bacteria, resulting in the outbreak of rot disease when conditions are suitable).
When snails harm the fruit, the fruit after eating forms a pit, which seriously affects the commerciality, and even acid rot and soft rot occur.
1. Manual capture;
2. Raise chickens, ducks and geese;
3. Spray salt water;
4. Tetraacetaldehyde granules sprinkled on fruit trays.
<h1>termite</h1>
Termites are extremely adaptable, the amount of reproduction is huge, coupled with often active in the ground, nests in the ground, termite nymphs nibble on the roots, resulting in weak growth of the tree, the root system is susceptible to a variety of pathogens, and even bite off the stem base when serious, resulting in the death of the whole plant.
When termite damage reaches a certain scale, it is often difficult to control.
1. Use high-efficiency cyfluthrin, chlorpyrifos, chlorpyrifosine, etc. to irrigate roots in termite nests near fruit discs;
2. Find termites on the tree, use high-efficiency cypermethrin, high chlorine chlorpyrifos to spray to kill.
