Description

Oranges and tangerines trypetid Synthetical prevention method based on PUSH-PULL strategies
Technical field
The present invention relates to a kind of oranges and tangerines trypetid class Synthetical prevention method based on PUSH-PULL strategies.
Background technology
Citrus fruit flyBactrocera minax(Enderlein), bactrocera tsuneonisTetradacus tsuneonis、 Dacus dorsalisBactrocera dorsalis (Hendel) Diptera is belonged to(Diptera)Tephritidae (Tephritidae), It is the crushing insect of oranges and tangerines.Wherein, there is a generation in two kinds big trypetid homogeneous years, specially endanger citrus fruits, citrus fruit fly There are many generations within 1 year, can endanger including planting fruit-trees more than 250, greengrocery fruit including oranges and tangerines.This several trypetid Adult worms producting eggs in In citrusfruit, larva brill moth tangerine fruit in tangerine valve pulp for food, cause wormed fruit it is underdone first Huang come off in advance and corruption, lose food With value, fruit General Loss rate about 20-30%, if taking measures not in time, fruit losses rate rapid growth in a short time, seriously Shi Keda 70%-80% are so that 100%, it has also become the important insect pest of China's Orange Producing, three kinds of insects in tangerine garden individually or mixing Occurrence injury, the situation is tense for prevention and control.
Citrus fruit fly has been reported that successively from the fifties in last century, China be distributed mainly on Hunan, Hubei, Sichuan, Chongqing, The areas such as Yunnan, Guizhou;Bactrocera tsuneonis are originated in the wild tangerine woods in EMUs for Kyushu of Japan south, since the sixties in last century, The ground such as China Sichuan, Guangxi, Guizhou, Yunnan, Hainan, Hunan, Jiangsu and Taiwan have been reported that successively, are China's agricultural and the plant that enters the territory Thing quarantine harmful organisms.Citrus fruit fly is typically distributed about the ground such as Sichuan, Guangdong, Guangxi, Fujian, Hunan, Yunnan and Taiwan, It is important plant quarantine object.
The conventional prevention and controls of current oranges and tangerines trypetid class have agrophysical preventing and treating, chemical prevention and biological control etc..Agricultural Physical control include pluck pick up the deinsectization of maggot fruit, winter ploughing go out the vexed desinsection of pupa, overlay film, the adult stage suspension lure bottle or oranges and tangerines blade face point spray lure Deng though worm amount can be reduced preferably, orangery still has wormed fruit rate higher;Chemical prevention is mainly included in oranges and tangerines foliage-spray Insecticide, and pupa time soil is closed down, and large area can cause environmental pollution, residues of pesticides and the anti-medicine of insect using insecticide Property etc., human and livestock health and environmental protection are influenceed, and often can not well control the moth of oranges and tangerines trypetid class really.In harm mandarin orange Tangerine area expands year by year, harm be on the rise in the case of, in the urgent need to research and development environmental protection, it is harmless to human and livestock health, Efficiently control the Prevention Technique of oranges and tangerines trypetid.
Due to adult free living, the nutritional supplementation phase before being laid eggs after emergence is main in the miscellaneous tree spinney on orangery periphery Perch, especially in orangery and the activity of spinney demarcation line, take food nectar, birds droppings and honeydew etc.,;Egg-laying season returns and is sought in orangery Find a mate mate and oviposit, it is also desirable to supplements the nutrients, therefore, the habit according to adult takes suitable prevention and control measure, as oranges and tangerines An important ring of the trypetid comprehensive regulation.Most widely used is trapping adult, at present mainly by various food attractants and property Attractant(The latter such as lures the methyl eugenol of citrus fruit fly), new attractant is also being researched and developed extensively both at home and abroad.Although these Lure can trap and kill a large amount of adults, but orangery wormed fruit rate is still higher, and control effect is still undesirable, be badly in need of research and development more reasonable, high The adult Control Technology of effect;Simultaneously as larva endangers only in fruit, upper one year brill moth larva in fruit treatment also into It is the important step of oranges and tangerines trypetid effectively preventing and treating.
Chinese patent application CN 105475050A disclose a kind of method of integrated control citrus fruit fly, biocidal The unearthed peak period of adult eclosion is included in, before not yet starting a large amount of matings, spawning, food attractant is sprayed, full garden sprays three points One of plant, every plant spray one-third of the area, continuously spray multiple food attractant;Physics breaks off worm sources to be included adopting Pluck, pick up maggot really, sink in methane-generating pit and kill, wormed fruit rate is reduced to less than 15% by original more than 85%.
In the above method, in citrus fruit fly adult occurrence in peak period, lure can substantially trap and kill many adults, and Largely reduce wormed fruit rate.But it is not to sprout wings the same period due to adult, lure is sprayed on orangery plant, in the egg-laying season Adult still has an opportunity to select to be laid eggs on citrusfruit into orangery, and this is control effect still dissatisfactory major reason; Furthermore, for the treatment for picking up wormed fruit, its open scheme uses methane-generating pit, and effect is fine, but simultaneously not all orchard worker has biogas Pond, and the older unused cracking of some biogas cement pits can not reach the basic demand for the treatment of wormed fruit, it is difficult to ensure wormed fruit Timely and effective treatment, therefore, the range of application of its technical scheme is limited.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, there is provided a kind of control effect is more preferable, simply It is easy, it is with low cost, it is easy to operation, range of application is wider, the environment-friendly oranges and tangerines trypetid synthesis based on PUSH-PULL strategies Preventing control method.
The technical solution adopted for the present invention to solve the technical problems is that the oranges and tangerines trypetid based on PUSH-PULL strategies is comprehensive Close preventing control method, including two prevention and control measures of link of adult stage and larval phase:
Adult stage, using Push-Pull strategies(Push-pull strategy)Rejection adult lays eggs into orangery, and traps and kills outside orangery. Adult eclosion and egg-laying season, odor barriers repellent adult is set up in orangery, blocking adult lays eggs into orangery, and is lured by food Adult is lured and is killed on orangery periphery by agent.Specific method is:Since adult eclosion requires supplementation with nutrition, in orangery oranges and tangerines leaf Repellant uniformly is sprayed on face and fruit, is sprayed once within every 7~15 days, drive reprimand trypetid adult is outside orangery;Meanwhile, use food Attractant, lures bottle, often at orangery periphery spinney bushes edge every 5~10 meters of point spray spinney bushes blade faces and suspension Add within 6~8 days spray food attractant and update the content lured in bottle.Above-mentioned measure can reach good prevention and control oranges and tangerines trypetid class The effect that adult lays eggs on citrusfruit.
The repellant, mainly by the ethanol extract of Siberian cocklebur powder, mineral oil(White oil, paraffin oil, white oil are also called, It includes machine oil emulsion)Mixture is formed.The preparation method of the ethanol extract of Siberian cocklebur powder:Folium Xanthii and fruit are taken, is dried in the shade naturally Dried in 45~55 DEG C of insulating boxs afterwards, 40 mesh sieves are crossed after crushed, obtain Siberian cocklebur powder;Every time with equivalent to Siberian cocklebur powder weight 4~6 Extracted 1~3 day under alcohol at normal temperature again, suction filtration after extraction, residue such as method continues to extract suction filtration, continuous to extract more than three times, with Active ingredient in Siberian cocklebur powder is fully extracted;Merge extract solution, sealing is saved backup after shady place.When using, take Siberian cocklebur powder ethanol extract is with mineral oil with volume ratio 4~6:1 mixing, is diluted with water to 100~800 times(It is preferred that 200~400 Times)Liquid, uniformly sprays in oranges and tangerines blade face and fruit surface.
Food attractant is mainly formed by following raw material mixture:10~20g of brown sugar, 80~120g of corn flour, dry ferment 10 ~20g, 4~6ml of ethyl acetate, 2~8ml of orange juice or 2~4ml of orange oil or 2~4ml of sweet orange monosodium glutamate oil, limonene or lemon 4~6ml of aldehyde, 4~6ml of citric acid or acetic acid, 90~120ml of water, 0.8~1g of methyl p-hydroxybenzoate or P-hydroxybenzoic acid 0.8~1g of methyl esters sodium.
The metrifonate for accounting for food attractant gross mass 1~3% can be added in food attractant, food attractant is made.
When suspension is lured bottle, food attractant is directly poured into luring bottle;Or food attractant is coated in the inwall for luring bottle, then During metrifonate dissolved in into water with the ratio of 0.2~1wt%, pour into and lure bottle.
It is described to lure bottle for yellow, orange, green, yellowish green alternate, yellow orange are alternate, orange is green alternate or colourless, preferably yellow or It is orange.
The method that the suspension of the present invention lures bottle:Bottle will be lured to be suspended on the moon of orangery periphery spinney bushes and orangery periphery Cool ventilation, highly according to the height of tree and branch distribution situation, hangs over the height in the middle part of tangerine, general liftoff 1.0~1.8m.Every Hang one for 5~10 meters and lure bottle.
The preparation method for luring bottle, referring to the section of CN104381329A specifications [0011st].
Larval phase, extract, pick up and treatment wormed fruit.In the wormed fruit underdone first Huang phase, extract in time the upper yellow of tree wormed fruit and The shedding for collecting ground is picked up, and focuses on wormed fruit deinsectization.
