Abstract
An attractant for the male moth of rice leaf roller is proportionally prepared from phenylmethanol, phenylformaldehyde and phenylacetaldehyde the rough mixing. Its advantages are high effect and high safety.
Description
Technical field
The present invention relates to the male Zeller attractant of a kind of rice leaf roller (Cnaphalocerocis medinalis), belong to field of pest control.
Background technology
Rice leaf roller is a kind of important pests that is distributed in China main paddy rice producing region, has the habit of migrating at a distance.
Rice leaf roller with larva at rice plant of tillering stage or booting, heading stage food evil paddy rice tender leaf or sword-like leave, very big to yield effect.When rice plant of tillering stage, cause harm, can have a strong impact on photosynthesis, rice growth is obstructed.The paddy rice sword-like leave more has direct influence as being injured to output, causes thousand kernel weight to reduce, and the blighted grain rate increases, and generally makes the paddy rice underproduction 10～15%, and heavy person can reach more than 50%.
All the time, to the control of rice leaf roller all based on chemical pesticide control.Because the excessive use of chemical pesticide has caused the severe contamination to environment, and natural enemy is come to harm, cause that bio-diversity sharply reduces in the paddy ecosystem, destroyed the paddy ecosystem balance.Therefore, seek and a kind of safety of exploitation, economy, otherwise effective technique, to replace chemical pesticide, the bio-diversity and the ecological balance in the protection paddy ecosystem have very important value.
Because rice leaf roller often produces ovum on rice strain blade; grain is laid eggs very easily by parasitisms such as multiple parasite such as rice borer oophagous trichogrammae, plan Australia oophagous trichogrammaes in institute;, natural enemy few as pesticide dosage is subjected in the rice field of better protection, and the ovum parasitic rate of rice leaf roller often reaches 50～80%.The control that these days, hostile follow-up rice leaf roller was caused harm will be played very crucial effect.So, unrestrictedly use agricultural chemicals, with the grievous injury natural enemy, weaken the control action of natural enemy to rice leaf roller.
Circling in the air of rice leaf roller adult is very competent, and some secondary metabolites that plant is produced especially volatile matter chemical substance have stronger taxis.Therefore; by from the volatile materials that plant produces, analyzing, filter out control and the prediction aspect that some compounds that the rice leaf roller adult is had a remarkable attractant effect are used for this insect; not only can prevent and treat effectively causing harm of rice leaf roller; and for the protection pest natural enemy, protection environment etc. has extremely important value.But, up to now, in production practices, still do not have the rice leaf roller imago attractant.
Summary of the invention
The present invention has filled up the blank of rice leaf roller trapping Prevention Technique, and a kind of attractant for male leaf-roller is provided.
This attractant is that phenmethylol, benzaldehyde, phenylacetaldehyde are made into by a certain percentage.Its component proportioning is:
Phenmethylol 50～95%
Benzaldehyde 4～40%
Phenylacetaldehyde 1～30%
Using method of the present invention is attractant to be joined to make in carrier such as the rubber core be used in combination with trapper after luring core together.
Useful result of the present invention is: 1, this attractant has the attractant effect of highly significant to the male moth of rice leaf roller, can be used for the prediction that the rice leaf roller field takes place and causes harm, and can be directly used in control; 2, constitute the equal platymiscium secondary metabolite of three kinds of components (phenmethylol, benzaldehyde and phenylacetaldehyde) of attractant,, do not injure natural enemy, environmentally safe the person poultry safety; 3, use cost is low, easy to operate.
Embodiment
Embodiment one
After phenmethylol, benzaldehyde, phenylacetaldehyde be mixed with different mixtures by proper ratio, get 0.05 milliliter mixture respectively and be added drop-wise to make in the rubber core after with 2 milliliters of carrene dilutions and lure core, be used for field trial.
During field experiment, make trapper with basin.In basin, add suitable quantity of water, in water, add a little washing powder.Be disposed across on the basin after will luring core to pass with iron wire.Lure core to be positioned at basin central authorities, dried up about about 1 centimetre.At dusk will lure core to put into the field every day, and regain morning next day, and check the borer population of traping in the basin.Each handles 3 repetitions.Blank.Test was carried out 5 days altogether.
Table 1 is used the result of attractant the male moth of field trapping rice leaf roller
| Lure (ratio * 100) | Field trapping amount (head) | |||||
| Handle | Phenmethylol | Benzaldehyde | Phenylacetaldehyde | Repeat 1 | Repeat 2 | Repeat 3 |

After will luring core and trapper to be placed on the field, the male moth of rice leaf roller is lured in the trapper by attractant, and is drowned and dead, thereby plays the effect of the male moth of trapping.From experimental result as can be seen, this attractant has significant attractant effect in the field to the male moth of rice leaf roller.
