What are the hazards of the melon fruit fly to the loofah? What pesticides can be used to control me

The larvae of the melon fruit fly are difficult to kill the eggs in the melon, and the damaged loofah will partially turn yellow, grow into a deformity, and the melon taste is bitter. It also lays eggs in the melon, and the larvae are harmful in the melon after the eggs hatch. Prevention and control methods:

Adult worms can be controlled with pesticides such as avermectin, emamectin salt, matrine, chlorpyrifos, etc.

Using needle bee Puke spray, I didn't expect the effect to be very good, and now there is no harm of melon fruit fly in the shed, and the yield and quality of bitter gourd and cucumber have been guaranteed.

It makes the loofah grow into a deformity, and in severe cases, it will rot. You can choose 50 tiger frog emulsifiable concentrate 500 times pesticide control. Spray once every 5 days, generally spray 2-3 times with medication.

Fertilization and watering should be carried out in a timely manner, and pest control should also be done. This pest is caused by the lack of timely spraying of pesticides and insufficient sunlight.

Because the larvae of the melon fruit fly burrow the fruit, it is more difficult to control it. Therefore, the main control measure is to trap and kill the adult fruit fly. Choose a good planting plot, and choose a field far away from the nectar source plant area for planting.

Mulching planting can reduce some insect sources. It is necessary to remove the fallen melons in time. Dig a deep pit near the melon field, add some chlorpyrifos liquid to the pit, and then add an appropriate amount of water, and concentrate all the collected melons into the puddle, and drown the larvae of the melon fruit fly that have not yet feathered in the bitter gourd to reduce the source of insects.

The reason for this is that the seed quality is not good enough before planting, and the daily management is not good. Water and fertilizer were not applied enough, and the pathogen was not cleaned up in time.

When planting bitter gourd, fertilize first, and then spray pesticides every day, so that the bitter gourd fruit fly can be reduced, and the bitter gourd fruit fly can also be prevented.

The first is to choose those varieties that are resistant to bitter gourd fruit flies to plant, and then spray them regularly.

These situations are also due to the lack of timely sunlight exposure, so there should be sufficient sunlight to ensure that these insect disasters are avoided, and some pesticides should be sprayed in time to deal with them.

If it is a large-scale planting of bitter gourd, you can install insecticidal lamps, in the period when there are many insects, you can use professional insecticides, and you should clean the bracket in time, otherwise it will attract bitter gourd fruit flies.

In addition to the cucumber, the melon fruit fly also harms bitter gourd, gourd, winter melon, pumpkin, loofah, gourd, bamboo shoots and other melon crops. The adult fruit fly pierces into the epidermis of the young melon through the oviposition tube to lay eggs, and the larvae burrow into the melon to feed after hatching. The victim melon first turned yellow locally, and then the whole melon rotted and smelly, and the melon, even if it was not rotten, the puncture wound sank, resulting in a flow of gum, the melon was deformed, the peel was hard, the melon taste was bitter, and the quality declined.

Prevention and control methods: 1) Poisonous bait traps and kills adult insects. Cook and ferment pumpkin or sweet potato, take 40 parts, add 1 part of pesticide, 1 part of flavor, 48 parts of water, mix it into a paste bait, directly apply it to the melon shed fence or put it into a container and hang it under the melon stand, 20 points per mu, put 25 30 grams per point, and trap and kill adults.

2) Remove the damaged melon in time, spray the rotten melon and fallen melon, and bury it deeply.

3) Medicinal protection of young melons. Spray 3000 times of 2% avermectin or 1000 times of 48% chlorpyrifos, 2000 times of 3% acetamiprid, and 3000 times of cyhalothrin EC during the peak period of adults. 1 time every 3 5 days, 2 3 times in a row.

It is also known as cucumber fruit fly, melon maggot, etc. The adult ovipositor pierces into the epidermis of the young melon to lay eggs, and the larvae are transferred to the melon to feed after the larvae. The victim melon turned yellow locally, and then the whole melon rotted and smelly, a large number of melons, even if it was not rotten, the thorn wound also condensed and flowed, deformed and sagging, the fruit was hard and solid, and the melon taste was bitter and astringent.

1) Morphological characteristics: The adult body is 8 mm long, yellowish-brown, with yellow longitudinal bands on the left and right sides of the anterior anus and the middle and hind anus, the wings are membranous and transparent, mixed with dark brown markings, and there are black longitudinal bands after the fourth segment of the abdomen. The eggs are elongated, about mm long, milky white. The mature larvae are 10 mm long, maggot-shaped, milky white.

The pupae are about 5 mm long, cylindrical, yellowish-brown. (2) Habits and pathogenesis occurred in 8 generations in South China a year, with overlapping generations, and adults overwintered in weeds. The following spring began in April, and in May and June, the damage was severe.

Adults are active during the day, and when the sun is high at noon in summer, they lie still in the melon shed or the back of the leaves, and the adults are tropic to aromatic substances such as sugar and wine. The female worm lays eggs in the young melon, and the larvae feed in the melon, and the melon eats into a honeycomb shape, so that it rots and falls off. Mature larvae bounce to the ground before or after the melon falls, burrow into the topsoil layer and pupate.

The egg stage is 5 8 days, the larvae are 4 to 15 days, the pupal stage is 7 to 10 days, and the adult life span is 25 days. (3) Prevention and control measures Agricultural prevention and control Cover the mulch film to prevent adults from burrowing into the topsoil layer and pupating. Remove the victim melon in time and dispose of it.

Pesticide control In the peak stage of adult worms, choose to spray deltamethrin emulsifiable concentrate 3000 times after noon and evening, or 21% synergistic cyano-horse emulsifiable concentrate 6000 times, or 50% maggotin 2000 times. Or use 40 parts of boiled and fermented pumpkin, 90% trichlorfon crystals, 1 part of essence, add water to make a paste of poisonous bait, directly smear on the skeleton of the shed or put it in the propaganda material under the cultivation frame, 667 meters 220 points, 25 grams per point, can trap and kill adults.

The control methods and some matters to be paid attention to in the melon fruit fly.

The adult worm of the melon fruit fly inserts the oviposition tube into the melon to lay eggs, and after hatching, the larvae eat the melon, and the mature larvae come out of the rotten melon and pupate into the soil. The South Asian oligomane fruit fly is a dangerous quarantine pest, and the known distribution areas in China include South China and Southwest China. The larvae have a bouncing habit and can bounce up to 5 to 30 cm tall.

The larvae bury the melon into a honeycomb shape, and the mature larvae can be popped out of the rotten melon or pupated with the rotten melon.

Control method: sweet and sour liquid traps adult insects (1 part of sugar, 3 parts of vinegar, 100 parts of water; or use melon juice and juice to add a little trichlorfon into a poisonous bait); spraying trichlorfon and phosphine solution; Young melon bagging to prevent adult eggs from laying eggs; Remove the rotten melons in time and bury them deeply.

With fruit fly viscose board, fruit fly trap, whether it is a fruit fly or a fruit fly, can be controlled, Quanzhou Lvpusen is the production company, waist horn five duration period bait six waist is.

The technique of using the mass proliferation of infertile insects of the melon fruit fly to completely eradicate the melon fruit fly.

Fruit flies, melon fruit flies, orange fruit flies, needle bees. It's annoying anyway! The melons and fruits are only green and astringent, and there are fruit flies standing on their heads!

It doesn't matter if you play, the melon fruit fly just injects "worm eggs" into the melon fruit, and when the melon fruit is about to ripen, the fly maggots inside will grow up, resulting in rotting and falling fruit, and the melon and fruit farmers will suffer heavy losses or even no harvest, but they are helpless!
