In order to further illustrate the feasibility of anomala corpulenta lure composition provided by the invention, describe below in conjunction with concrete test.
Carrying out synergist on July 5th, 2013 to August 10 in Zhao Zhai village, Gao Long town, Luoyang City Yanshi City coordinates anomala corpulenta sex pheromone to lure the trap effect test of core.
The purity of component geraniol, eugenol and the phenylethyl propionate of synergist all can be purchased from ACROS or Aladdin company at the above compound of 99%().
Geraniol, eugenol and phenylethyl propionate are dissolved in n-hexane separately with the concentration of 100~900 ug/ml respectively, getting 1 milliliter of gradation drips on the partition of the rubber stopper cleaning with n-hexane, after n-hexane volatilization, 1 milliliter of carrene gradation is dripped, after carrene volatilization, make synergist and lure core.Lure core to pack in aluminium foil the synergist of single, two components of making and three components and seal, at-20 DEG C, preserve.
Described anomala corpulenta sex pheromone lures the preparation method of core 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 in the present embodiment this most preferred part by weight.
Step 2, the mixture that step 1 is obtained are dissolved in n-hexane according to a certain percentage, and the n-hexane pheromones solution concentration of preparation is about 100~1000 ug/ml conventionally, and what in the present embodiment, use is 600 ug/ml.
Step 3, pheromones solution (the approximately 2 milliliters) gradation that step 2 is obtained are added drop-wise to blank rubber and lure on core, and it is 1200 micrograms/lure cores that the anomala corpulenta sex pheromone obtaining lures the dosage of the pheromones containing on core.In experiment, to lure anomala corpulenta described in core be that sex pheromone lures approximately 1 milliliter of gradation of solution that core obtains step 2 to be added drop-wise to blank rubber to lure on core in combination, and it is 600 micrograms/lure cores that the anomala corpulenta sex pheromone obtaining lures the dosage of the pheromones containing on core.
Trap test during in field, lure core to be fixed on Scarab trapper epimere (Scarab trapper is purchased from Pherobio Technology Co., Ltd.) synergist with thin wire, trapper is suspended on to peanut varieties, growing way, rich water quality management term harmonization, the area Peanut Fields in flakes more than 10 mu, coordinates anomala corpulenta sex pheromone to lure core jointly to use simultaneously.
The object of reference of this series comparative trial is that anomala corpulenta sex pheromone lures core.Trapper is arranged to three repetitions, randomized arrangement.After arranging, from second day, the anomala corpulenta quantity that every morning, record was traped was also removed it in time, continues investigation 30 days.Result of the test is in table 2.

In the test data of table 1, control group (01) is not for to use synergist to lure the effect of core; 02 to 04 group is that collocation A. Corpulenta sex pheromone lures core to use a kind of composition synergist to lure the effect of core; 05 to 28 group is that collocation A. Corpulenta sex pheromone lures core to use two kinds of composition synergists to lure the effect of core; 29 to 56 groups is that collocation A. Corpulenta sex pheromone lures core to use three kinds of composition synergists to lure the effect of core.As can be seen from the table, used contain A. Corpulenta sex pheromone synergist of the present invention lure core after, sex pheromone lures the trapping efficiency of core obviously to strengthen, 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 lures core and anomala corpulenta sex pheromone to lure core to be used in conjunction with, also anomala corpulenta sex pheromone solution can be mixed with its synergist solution, make lure composition and lure core to use; Multiple components can freely be selected independent use, or jointly uses according to proportioning, and independence is stronger; 2) with only containing anomala corpulenta sex pheromone containing the luring compared with core of its synergist, use the core that lures that contains anomala corpulenta sex pheromone and synergist composition thereof to show stronger trapping activity in the anomala corpulenta trapping test in field; 3) synergist composition provided by the invention is cheap, can reduce and make the cost that lures 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, interference mating, significant for comprehensive regulation anomala corpulenta.And this anomala corpulenta lure composition preparation is simple, uses simply, condition is feasible, has very strong trapping capability, good stability; Meanwhile, this anomala corpulenta lure composition selectivity is strong, does not produce resistance, and natural enemy is not injured, 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 of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
