In order to further illustrate the feasibility of anomala corpulenta lure composition provided by the invention, be described below in conjunction with concrete test.
The trap effect test that synergist coordinates anomala corpulenta sex pheromone lure core is carried out on July 5th, 2013 to August 10 in Zhao Zhai village, Gao Long town, Luoyang City Yanshi City.
The purity of the component geraniol of synergist, eugenol and phenylethyl propionate all can be purchased from ACROS or Aladdin company at more than 99%(compound).
Geraniol, eugenol and phenylethyl propionate are dissolved in n-hexane separately with the concentration of 100 ~ 900 mcg/ml respectively, getting 1 milliliter of gradation drips on the partition of the rubber stopper cleaned with n-hexane, 1 milliliter of carrene gradation dripped after n-hexane volatilization, after carrene volatilization, namely obtained synergist lures core.Lure core to load in aluminium foil the synergist of single, two components made and three components to seal, preserve at-20 DEG C.
The preparation method of described anomala corpulenta sex pheromone lure core is as follows:
Step 1, by following three kinds of compounds:
5-myristyl dihydro-2 (3H)-furanone, 2,2,7-trimethyl decane and 2-propyl enanthol fully mix (above compound can be purchased from ACROS or Aladdin company) according to constant weight ratio, common part by weight is 1 ~ 9:1 ~ 9.8:1 ~ 9, most preferably be 2:5:3, use this most preferred part by weight in the present embodiment.
Step 2, mixture step 1 obtained are dissolved in n-hexane according to a certain percentage, and the n-hexane pheromones solution concentration of preparation is usually about 100 ~ 1000 mcg/ml, and what use in the present embodiment is 600 mcg/ml.
Step 3, pheromones solution (about 2 milliliters) gradation step 2 obtained are added drop-wise to blank rubber and lure on core, and the dosage of the pheromones that the anomala corpulenta sex pheromone lure core obtained contains is 1200 micrograms/lure core.In experiment, combination lures anomala corpulenta described in core to be that solution about 1 milliliter of gradation that step 2 obtains by sex pheromone lure core is added drop-wise to blank rubber and lures on core, and the dosage of the pheromones that the anomala corpulenta sex pheromone lure core obtained contains is 600 micrograms/lure core.
When carrying out trapping experiments in field, core is lured to be fixed on Scarab trapper epimere (Scarab trapper is purchased from Pherobio Technology Co., Ltd.) synergist with thin wire, trapper is suspended on peanut varieties, growing way, rich water quality management are consistent, the in flakes Peanut Fields of area more than 10 mu, coordinates anomala corpulenta sex pheromone lure core jointly to use simultaneously.
The object of reference of this serial comparative trial is anomala corpulenta sex pheromone lure core.Trapper is arranged three repetitions, randomized arrangement.After arranging from second day, it also removes by anomala corpulenta quantity that every morning, record was traped in time, continues investigation 30 days.Result of the test is in table 2.
Table 1
Synergist described in table 1 is as shown in table 2 below.
Table 2
| Composition | Molecular formula | Molecular weight | There is plant in natural product |
| Geraniol | C 10H 18O | 154 | Rose etc. |
| Eugenol | C 10H 12O 2 | 164 | Plant clove of myrtaceae etc. |
| Phenylethyl propionate | C 11H 14O 2 | 178 | Peanut etc. |
In the test data of table 1, control group (01) is not for use synergist to lure the effect of core; 02 to 04 group is that collocation A. Corpulenta sex pheromone lure core uses a kind of composition synergist to lure the effect of core; 05 to 28 group is that collocation A. Corpulenta sex pheromone lure core uses two kinds of composition synergists to lure the effect of core; 29 to 56 groups are that collocation A. Corpulenta sex pheromone lure core uses three kinds of composition synergists to lure the effect of core.As can be seen from the table, employ containing A. Corpulenta sex pheromone synergist of the present invention lure core after, the trapping efficiency of sex pheromone lure core obviously strengthens, and the consumption of sex pheromone greatly reduces.
As can be seen here, the invention has the advantages that: 1) occupation mode is flexible, anomala corpulenta lure composition provided by the invention, comprise anomala corpulenta sex pheromone and synergist thereof, can make synergist lure core and anomala corpulenta sex pheromone lure core with the use of, also anomala corpulenta sex pheromone solution can be mixed with its synergist solution, make lure composition and lure core to use; Multiple components can be used alone by unrestricted choice, or jointly uses according to proportioning, and independence is stronger; 2) with lure compared with core only containing anomala corpulenta sex pheromone containing its synergist, use containing anomala corpulenta sex pheromone and synergist composition thereof to lure core in the anomala corpulenta trapping experiments in field, show stronger trapping active; 3) synergist composition provided by the invention is cheap, can reduce the cost making and lure core, suitable penetration and promotion.
Anomala corpulenta lure composition provided by the invention can accurately be applied to anomala corpulenta detecting and reporting pest information, mass trapping, Insect pest suppression, significant for comprehensive regulation anomala corpulenta.And the preparation of this anomala corpulenta lure composition is simple, use simple, condition is feasible, has very strong trapping capability, good stability; Meanwhile, this anomala corpulenta lure composition selectivity is strong, does not produce resistance, does not injure natural enemy, nontoxic to people and animals, environmental friendliness; Strong stress resistance, is not afraid of wind, rainforest and Exposure to Sunlight; Lasting period is long, and control efficiency can maintain more than 30 days.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
