Description
Technical field
Lure synergist and manufacturing approach thereof the preoviposition period of the present invention relates to a kind of Monochamus alternatus, belong to techniques of pest control field.
Background technology
Monochamus alternatus claims that again Monochamus alternatus Hope Monchamus alternatus Hope is the topmost communication media of pine wood nematode, and its medicament is difficult to touch polypide with its natural enemy, has characteristics such as harm is heavy, disguised by force, difficulty of prevention and cure is big.It is distributed widely in states such as China, Korea, Laos, Vietnam and Japan, mainly is distributed in most of areas on the south the Huanghe valley in China.The host range of Monochamus alternatus is quite extensive; Comprise Pinus, Larch, Cedrus, abies and Picea etc.; Wherein have a liking for most food masson pine, black pine and Japanese red pine, the more weak pine tree of its larva harm growing way, it dredges tissue to destroy cut-out; Influence the transportation of nutrition and moisture, thereby cause pine death.In addition, the control Monochamus alternatus is the important channel that alleviates pine wood nematode and pine nematode harm.At present, the susceptible lethality of woodland pine tree has been increased to present more than 60% from 10% of the eighties in last century.Therefore, seek the anti-control techniques of effective Monochamus alternatus and become current instant task.
Using the main method of preventing and treating Monochamus alternatus in practice has: chemical control----punching injection pesticide control larva, though its very difficult large-area applications of certain effect is arranged; Large tracts of land is sprayed insecticide to reduce to a certain extent and is gone quantity to reduce insect density in the adult, but environment and natural enemy are all had certain influence, in addition since factors such as the adult individual activity cycle is short, the time disunity of sprouting wings to influence its enforcement difficulty bigger.Biological control receives the influence of natural environment, and its control efficiency is also undesirable.Physical control mainly is that the sick tree of the dead tree of Monochamus alternatus harm is cleared up, and is main through method such as burning, stifling, but the method consumptive material consumes power, has certain limitation.And attractant trapping Monochamus alternatus is a kind of effective means that suppresses the nuisanceless ecology of its population quantity, in the nuisanceless comprehensive regulation of this type of pest of control, plays a significant role, and on producing, obtains using more widely.That this information inducing substance has is efficient, nontoxic, do not injure beneficial insect, be difficult for producing resistance, free from environmental pollution, to characteristics such as plant are nuisanceless; It obviously acts in detecting and reporting pest information and damage by disease and insect integrated management and is approved, and becomes the present new focus of control of insect application study in the world day by day.
Although the gloomy guarantor worker of China utilizes the population quantity of information attractant at the monitoring Monochamus alternatus imago, effectively reduce insect density, diffusion naturally of containment pine nematode the aspect such as spreads and has carried out Primary Study, and plays a positive role preventing and treating this insect.But in practical application, control efficiency is not ideal enough.At present, the attractant that is applied in the production mainly contains: M-99, Mat-1 and FJ-MA-02 etc.These attractants all have certain attracting action to Monochamus alternatus, as only the adult in 2 weeks of sprouting wings being had attractant effect; Lure that the evaporation rate of attractant is not effectively controlled in the core, the attractive activity cycle is shorter, need constantly add attractant, brings great inconvenience to practical operation; Grope by experience and field test more simultaneously, have limitation in technology aspect analysis, evaluation and the biologicall test of the active component of attractant and synergistic component etc.Therefore, research and develop as early as possible China's Monochamus alternatus new, high-efficiency information lures synergist to be significant.
By Zhao Jin of Inst. of Subtropical Forestry, Chinese Academy of Forestry Sciences etc.; On the basis of selecting monoterpene, rosin, turpentine oil, ethanol, isopropyl alcohol, acetaldehyde, acetone, benzoic acid, eugenol etc. for use, add organic solvent (synergist) and active ingredient and connect the different component different proportion and be configured, the M-99 attractant that is developed into has attractant effect preferably to Monochamus alternatus.Its making that lures core is to be to seal in the Bottle cap connected with bottle about 350ml promptly to process to lure core with the 300ml attractant capacity of being placed on that configures, and its attractive activity is higher than domestic its outer other attractants.At present, use in a plurality of Monochamus alternatus harm district occurred frequently, still, its preoviposition period attractant effect not ideal enough, and luring aspect practical values such as core duration, cost, labour not good enough.
But there is following shortcoming:
1. owing to lure the making of core comparatively extensive, its evaporation rate is not effectively controlled, and lures the cycle shorter, and is efficient low, and it lures core to need the heaven-made back of 10-15 to change, to strengthen attractant effect.Therefore, this attractant makes cost increase and increases difficulty for the woodland practical operation.
2. this product has better attractant effect to the Monochamus alternatus in egg-laying period, and the attractive activity to Monochamus alternatus the preoviposition period is low.The average fish brood amount of the adult that attractant is traped is lower, and this type attractant is described, helps reducing the Monochamus alternatus population quantity, or as the method for woodland population monitoring, but can not cut off the pine wood nematode route of transmission.
Summary of the invention
The objective of the invention is to overcome the weak point of existing attractant, a kind of Monochamus alternatus better effects if of more luring is provided, cost is lower, and duration of efficacy Monochamus alternatus more of a specified duration is lured synergist.

2(market can be bought, and structural formula is following), above-mentioned substance were according to weight ratio 0.5: 5: 3: 2: 1: 1: 1: 2: 1: 0.5 mixed formed.
Monochamus alternatus of the present invention lures the manufacturing approach of synergist to be: with the above-mentioned substance mixture add stir in the conventional vessel after, adorn with the polyethylene pipe with slow releasing function in seal, promptly process the Monochamus alternatus attractant.
With the present invention process attractant lure core and M-99 attractant (market purchase) lure core as contrast, carry out the test of Monochamus alternatus trap effect on Fuyang, Zhejiang Ye Wu ridge on May 16th, 2008 to July 6.
Xuanzhou, experiment selected Anhui produces hits board-like funnel type trapper.Trapper is processed by horse spoken parts in an opera iron sheet; The top is the umbrella hood of footpath, end 41cm; It is down the retaining worm plate of 4 one-tenth " ten " word intersection of long 50cm, wide 13cm; What a diameter 10cm, high 16cm were installed in the middle top of plate is used to place the cylindrical neutral gear that lures core, is covered with the circular hole of diameter 0.14cm near the retaining worm edges of boards of neutral gear; Below retaining worm plate, connect the funnel (go up bore 41cm, following bore 9cm, funnel neck length 12cm, hopper walls become 45 ° of angles with vertical plane) that is used to collect longicorn.Lure core and M-99 that the present invention is developed into lure core to be suspended on the central neutral gear place of trapper; Fixedly lure core; Open sealed bag (the M-99 attractant lures core need open bottle cap), make volatile materials slow release (the M-99 attractant lures core to need 10-15d replacing at interval 1 time, and all the other are not changed); Then trapper is arranged on mountain top, forest-road both sides air than circulation place.On path both sides, ridge or hill-side, the air part that circulates is selected the above pine tree at a distance of 3m, and each trapper height is 1.5-2.0m overhead, and trapper is fixed between the two strains tree with the iron wire suspension.Collect the Monochamus alternatus of traping respectively based on the every 3-7 of weather condition days, collect each trapper simultaneously and lure the insect that collects, respectively record data.Data result sees the following form:
Table 1 difference is lured the comparison of synergist to the Monochamus alternatus attractant effect
| Lure core | The trapping sum | Property than (♂/ | Average trapping amount | Nematode amount (thousand | Fish brood amount (individual) |
| Lure | (head) | ♀) | (head) | Head) | |
| exo-brevicomin | 35 | 25/10 | 7.0±1.38b | 30.50 | 124 |
| M-99 lures core | 35 | 15/20 | 7.0±1.5b | 39.25 | 229 |
| Clear water (contrast) | 3 | 2/1 | 0.6±0.25a | 0 | 16 |
On P＜0.05 level, adopt the Duncan check to make difference analysis between the different disposal.
Learn that from last table although the adult that synergist exo-brevicomin traps sum is suitable with M-99, the fish brood amount of every female worm is about 12.5, is significantly higher than the latter, this show this synergist to the preoviposition period the attractant effect of female worm obviously be superior to the latter.At present, the common fatal shortcoming of Monochamus alternatus Hope attractant is only the female adult worm of post-egg stage to be had attractant effect, and firm emergence is supplemented the nutrients the phase, i.e. Monochamus alternatus Hope attractant effect the preoviposition period very a little less than.This synergist compensates its defect just.
Other insects that attractant of the present invention when Monochamus alternatus is traped see table 2.
Other insects that table 2 attractant of the present invention is traped
Can draw by table 2, elytrum purpose most species in the insect of traping, remaining also has Homoptera, Neuroptera etc.Experiment statistics is the result show, short pyramid longicorn of traping and the quantity of two spot ponderous borers are maximum, and the difference of its quantity and Monochamus alternatus is little.This shows that attractant of the present invention also has certain trap effect to other insects except Monochamus alternatus being had attractant effect.
The present invention is to Monochamus alternatus imago the preoviposition period; Promptly the extra-nutrition stage has attractant effect preferably; Simultaneously, this attractant is selected the special slowly-releasing pipe with slow releasing function for use, and it can prolong rate of release; Need not change in the whole phase of luring and to lure core, solve the M-99 attractant and needed constantly to add the shortcoming of attractant, reduced cost, alleviated the labour.Therefore, attractant of the present invention is used at woodland and is had broad prospects.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
