Comprehensive Preventing control method of the present invention is according to as follows:

1, grasps the pests occurrence rule of potted plant banyan advantage thrips

But potted plant banyan advantage thrips-banyan pipe thrips occurs in the torrid zone and most of subtropical zone anniversary, and the annual 5-6 month and the 9-10 month cause harm seriously.Many generations (13-l5 generation) can occur in 1 year, and generation and temperature relation are close, and be maximum period of this worm generating capacity annual June, in average each leaf goitre worm l3 head is arranged, borer population reaches 100 in each maximum leaf goitres, and the leaf goitre has ovum rate l8.7%-100%, average out to 74.2%; In per generation,, required time was different according to season, the 1-4 month buries and pupates, the 5-l2 month pupates in the leaf goitre, four age nymph mostly loosen the soil the layer or the leaf branch slit in pupate, grow slowly without the phenomenon of significantly surviving the winter winter, and the insect population number reduces, generation time approximately needs 50 days, raise to grow with temperature later on and accelerate, generation time is about 20 days, when 7-8 month temperature is too high, grow and slow down to some extent, about generation time 30 days, because growth algebraically is many, the generation overlap phenomenon is serious, almost all can see adult, nymph and ovum, often with adults throughout the year.

This worm growth thermophilic is 25 ℃ and (is reported as 24-27 ℃, when temperature reaches more than 33 ℃, eclosion rate and incubation rate reduce, and lethality improves), relative moisture 50%-70%, general arid season harm is rampant, then unfavorable (rainfall particularly continues rainfall and causes the insect gall internal water accumulation high temperature and rainy, can directly kill the part thrips to its generation, force down insect density, thereby thrips is easy to lead to disaster at arid season and area).When 25 ℃ of daily mean temperatures, finishing for 1 generation needs 28-30 days, and average 29 days, 1st generation appearred in annual January, occurred for the 9th generation at the beginning of 11 months, and entered during Wintering Period.7-10 point and 16-19 point are pupated or are sprouted wings in 1 day, and pupation rate is different with eclosion rate under the condition of different temperatures and humidity.Carried out mating in 2-3 days behind the adult eclosion, 5-7 days begin to lay eggs, and ovum is output in batches, and is irregular.Every female adult can produce 25-81 grain ovum all one's life, and average 71, fecund is in dumpling shape insect gall, and some adults go out insect gall ovum is originated in the bark crack, and the size of egg laying amount is relevant with factors such as food, temperature.Ovum is block in insect gall arranges, and goes through phase 2-20 days, and temperature is higher, and to go through the phase shorter, and summer high temperature reaches that egg development slows down more than 35 ℃, ovum stasi when room temperature reaches more than 37 ℃.Egg development red eyespot occurs to the later stage, and indication will be hatched.Nymph moves in the leaf goitre of dumpling shape, and file is inhaled the juice of potted plant banyan tender leaf.

This worm is liked being clustered in and is injured in the insect gall that leaf grows up to, and has a liking for the food Ficus microcarpa leaf, and is heavier with the harm of low age banyan generally speaking.The adult belly has the moving habit of tilting upward, and only has and just flies when frightened, generally takes food or shifts leaf and cause harm by crawling into other places.Can be attached on host plant and the vehicles artificially or mechanically from first be diffused into second ground.Cause harm thrips also spinosity leg pipe thrips and the thigh banyan pipe thrips of potted plant banyan, they tend to cause harm in same insect gall with banyan pipe thrips, but the negligible amounts that occurs.

2, carry out Insect infestation monitoring and observing and predicting

Pests occurrence rule according to potted plant banyan advantage thrips-banyan pipe thrips, in conjunction with local weather conditions, natural enemy situation and potted plant banyan growth and development state, period of use (is the beginning of utilizing each worm attitude to occur to contain the phase apart from method, the method that peak period or Sheng interlude range prediction in latter stage insect occur, by luring the collection method, artificial feeded method, field investigation method statistics is tried to achieve), the phenology method (is to utilize a kind of biology and him to plant between the biology to live, the correlation of g and D and rule, a kind of method as the prediction insect pest), the effective accumulated temperature method (is the method for utilizing the effective temperature summation forecasdt insect generation of insect growth, is formulated: K=N(T-C); K: effective accumulated temperature, N: grow fate; T: actual temperature: C: threshold of development.) etc. method, perform the prediction of this worm.

3, Comprehensive Preventing control method

The Comprehensive Preventing control method of potted plant banyan advantage thrips, follow the plant protection policy of " putting prevention first; integrated control ", at the different vegetative stages of potted plant banyan, use prophylactico-therapeutic measuress such as " plant quarantine, Insect infestation monitoring, gardening control, physical control, biological control and chemical control ", making up quarantine, isolation, clean seedling, garden pipe (canopy pipe, garden pipe, chamber pipe and ground pipe), trapping, biological and ecological methods to prevent plant disease, pests, and erosion and medicine control is the prevention and control technical system of core.

Main prevention and control measure:

(1) plant quarantine

Potted plant banyan advantage thrips polypide is little, and is movable hidden, and the distance of circling in the air under field conditions (factors) is shorter, and the possibility that enlarging distributes causes harm is less, but the easy long-distance communications of carrying out with nursery stock and soil etc.Therefore the time should strengthen quarantine in allocation and transportation, strict implement plant quarantine system will in time be processed when finding thrips is arranged, and tries hard to be not introduce, export with the nursery stock of thrips etc., prevents that thrips from artificially spreading.

(2) Insect infestation monitoring

But potted plant banyan advantage thrips occurs in the torrid zone and most of subtropical zone anniversary, and the annual 5-6 month and the 9-10 month cause harm seriously.In these two time periods, should be in conjunction with weather conditions, natural enemy situation and the growth and development of plants situation of locality, period of use,, emphasis performed the prediction of this worm apart from methods such as method (trying to achieve by luring collection, raising, field investigation and statistics), phenology method, effective accumulated temperature methods.

(3) gardening control

1. pay attention to the seedling seed selection

Seed breeding: the seed vigor of fresh, full, ripe (pericarp is by the green purple that reddens), free from insect pests is stronger, and germination rate is high.To clean, go exocarp, vernalization to kind of a fruit before the sowing, and adopt the agricultural chemicals of environmentally safe to carry out strict sterilization, reduce disease worm source.

Healthy seedling seed selection: when growing seedlings and before the field planting, consider the quality of nursery stock.The plant percent of healthy and strong high-quality is higher, and insect resistance capacity is stronger, caused harm gently by potted plant banyan advantage thrips, takes out the tip, come into leaves fast.

Resistance seedling seed selection: during the greenhouse moulding, should take into full account anti-, the susceptibility of kind.Test shows, the different banyan kinds of same breeding time are subjected to the potted plant banyan advantage thrips degree difference that causes harm, and the heaviest with banyan, ginseng banyan and floral leaf banyan take second place, and gold leaf banyan, black leaf rubber banyan and variegated leaf rubber banyan are extremely light.Therefore, during the greenhouse moulding, can improve the resistance to insects of plant in the root top grafting high resistance kind of low anti-kind, reduce potted plant banyan advantage thrips and cause harm.

2. strengthen managing between the garden

Carry out seedling growth greenhouse, nursery, greenhouse and support sanitation and hygiene and weed control and the desinsection work of managing ground.Nursery soil need through immersion, dig, sterilization and whole furrow, kill the thrips in the soil.Strengthen cultivation management between planting season, watering, fertilizing improves the plant resistance in good time; In time clean dry branches and fallen leaves and weeds, and in conjunction with pruning, wipe out overstocked branch, deadwood, sick branch, the excision insect gall to improve the ventilation illumination condition, reduces the worm source.

3. carry out efficent rotation

Behind the nursery planting banyan 1-2, answer the not equal vegetables of crop rotation plantation, to recover soil fertility, the generation that can alleviate damage by disease and insect simultaneously.

(4) physical control

1. fly net isolation

Carry out seedling growth greenhouse, greenhouse and support canopy film, the door and window on pipe ground, the ordinary maintenance maintenance work of fly net, ensure or strengthen these local physics every worm, insect protected function.

2. colour table, lure and light trap

In the nursery, greenhouse and support pipe ground coloured haftplatte, gyplure and light trap are set, lure integrated worm, can reduce and lay eggs and cause harm, effectively reduce insect population quantity, the consumption of minimizing chemical pesticide.

(5) biological control

Utilizing biocontrol microorganisms and natural enemy is commonly used in the biological control and effective method.Lecanium is mould to be one of important kind of biocontrol microorganisms, and geographical distribution and host range are all more extensive, and secondary metabolite-toxin has better activity to target pest, and comparatively safe to natural enemy, and potted plant banyan advantage thrips is had preferably control action.Laboratory test results shows, lecanium is mould to have the effect of infecting to potted plant banyan advantage thrips, wherein V07, VP28, V3450 and V16063(V07: originating is that Yuexi, Anhui, host are Lepidoptera Lepidoptera insect; VP28 and V3450: originating is that Guangzhou Guangdong, host are Bemisia tabaci Bemisia tabaciV16063: originating is that Canada, host are Trialeurodes vaporariorum Westwood Trrialeurodes vaporarioum) etc. the infection ability of bacterial strain stronger, can be used for the prevention and control of this worm of prevention and control.In addition; the hostile potted plant banyan advantage thrips in sky such as ladybug (coccinella septempunctata, Propylaea japonica etc.), Hua Yeji hunt stinkbug, band thrips, Cabir letter pipe thrips, post letter pipe thrips, chalcid fly nibbles in sliding flower stinkbug, black line clearwing flower stinkbug, black line wing flower stinkbug, Similis, Chinese green lacewing, chrysopa septempunctata, eight spot thin,tough silk Chrysopas, dotted line arteries and veins Chrysopa, bar syrphus fly and clan also have certain control action, also should be protected utilization.

(6) chemical control

The potted plant banyan advantage thrips blade of causing harm forms dumpling shape or pimple shape insect gall, and polypide is hidden and wherein perches, lives and breed, and non-special agent can not produce preferably control efficiency to it, and difficulty of prevention and cure is larger.Test shows, with meta-tolyl-N-methylcarbamate (MTMC)+500-1500 times of liquid of Acetamiprid 4:1 effective ingredient proportioning, 1200 times of liquid of 48% chlorpyrifos ec, 1000 times of liquid of 2.5% dish happiness suspending agent, 1000 times of liquid of the safe water dispersible granules of 25% Acker, 52.25% chlopyrifos+1500 times of liquid of permethrin milk oil, 800 times of liquid of 4.5% r, 1000 times of liquid of 3% acetamiprid EC, 500 times of liquid of 0.9% northern agricultural avermectin oil slick, 800 times of liquid of 10% worm hydrazides missible oil, 1500 times of liquid of ethyl pleocidin suspending agent, 1500 times of liquid of 90% Methomyl soluble powder, 1200 times of liquid of 20% carbosulfan missible oil, 500 times of liquid of 5% Imidacloprid missible oil, 2.2% first dimension, 800 times of liquid of salt microemulsion and 10% eliminate 1000 times of liquid sprayings of suspending agent, every spray in 5-7 days 1 time, connect and spray 2-3 time, or with the seed soaking of 6000-8000 times of liquid of 25% Diacloden water dispersible granules, seedling is filled with root, and control efficiency is better.When making with medicament, rotate as far as possible or be used alternatingly, delay the generation of high resistance individuality; Simultaneously, should catch the optimum period for applying fertilizer, take out the tip or adult rotating vane harm spray medicine when not yet forming insect gall in banyan, increase contact probability, contact area and the Exposure of polypide and medicament, further improve control efficiency.

The Prevention Technique main points:

(1) quarantine

Perform quarantine, find band worm nursery stock, in time process, control potted plant banyan advantage thrips initial population quantity.

(2) isolation
