Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Test No.): antennal potential (EAG) determination
The determination method comprises the following steps: the tentacles of mated adult cotton bollworms were cut from the base, 2 whips at the end were removed, and then connected to an antennal potentiostat. 20 μ L of the sample solution to be tested were applied uniformly to a filter paper strip (6.0cmx0.5cm) which was immediately placed in a Pasteur tube and connected to a stimulating air flow. During the test, the flow rate of the stimulating airflow is 25mL/min, and the flow rate of the continuous airflow is 120 mL/min; after the baseline is stabilized, the stimulation is given, the single stimulation lasts for 0.2s, and the time interval of 2 continuous stimulations is more than 30 s. Each antenna was repeated 10 times and 3 bollworms were repeated. With dichloromethane as control and cis-3-hexenol as standard compound, the test concentration is 10-4Volume ratio.
Relative EAG reaction (%) is (reaction of sample-reaction of control)/(reaction of reference-reaction of control) x100
TABLE 1 EAG reaction of Heliothis armigera to plant volatiles
As can be seen from Table 1, the reaction of the plant volatile matters on the cotton bollworm antennal potential is obvious, wherein the benzaldehyde, trans-2-hexenal, n-heptanal, salicylaldehyde, n-octanol, benzyl alcohol, amyl alcohol, phenethyl alcohol and benzyl acetate have larger reaction values and have stronger stimulation on the cotton bollworm.
Test No. two: attraction effect of different attractant formulas on cotton bollworms
Formula composition (the weight ratio of each component is 1:1)
Group A: benzaldehyde, trans-2-hexenal and n-octanol
Group B: benzaldehyde + n-heptanal + n-octanol
Group C: benzaldehyde, salicylaldehyde and n-octanol
Group D: benzaldehyde, trans-2-hexenal, n-heptanal and n-octanol
Group E: benzaldehyde, salicylaldehyde, n-heptaldehyde and n-octanol
Group F benzaldehyde + n-octanol + benzyl acetate
Group G: benzaldehyde + benzyl alcohol + benzyl acetate
Group H: benzaldehyde + pentanol + benzyl acetate
Group I: benzaldehyde + phenethyl alcohol + benzyl acetate
Group J: benzaldehyde + n-octanol + benzyl alcohol + benzyl acetate
Group K: benzaldehyde + n-octanol + pentanol + benzyl acetate
Group L: benzaldehyde + n-octanol + phenethyl alcohol + benzyl acetate
Group M: benzaldehyde, salicylaldehyde, n-heptaldehyde, n-octanol, phenethyl alcohol and benzyl acetate
Group N: benzaldehyde + salicylaldehyde + n-heptanal + pentanol + benzyl alcohol
The test method comprises the following steps: placing a proper amount of the composition into a slow-release bottle, placing the bottle in the field, carrying out an attraction test in the adult cotton bollworm generation period, and checking the attraction effect after 7 days.
TABLE 2 attraction of bollworm by different attractant formulations
As can be seen from Table 2, the attraction effect of the cotton bollworm is different when different plant volatiles are used in combination; the effective rate of the group E, the group L, the group M and the group N to the cotton bollworm is more than 20, wherein the formula of the group M is the optimal formula, namely the attractant comprises benzaldehyde, salicylaldehyde, N-heptaldehyde, N-octanol, phenethyl alcohol and benzyl acetate.
Experiment three: attractant with different proportions for attracting cotton bollworms
The formula of the attractant is as follows:
attractant 1: 10 parts of benzaldehyde, 4 parts of salicylaldehyde, 3 parts of n-heptaldehyde, 12 parts of n-octanol, 3 parts of phenethyl alcohol and 6 parts of benzyl acetate.
Attractant 2: 15 parts of benzaldehyde, 3 parts of salicylaldehyde, 4 parts of n-heptaldehyde, 10 parts of n-octanol, 5 parts of phenethyl alcohol and 5 parts of benzyl acetate.
Attractant 3: 20 parts of benzaldehyde, 2 parts of salicylaldehyde, 6 parts of n-heptaldehyde, 5 parts of n-octanol, 7 parts of phenethyl alcohol and 6 parts of benzyl acetate.
Attractant 4: 16 parts of benzaldehyde, 1 part of salicylaldehyde, 2 parts of n-heptaldehyde, 15 parts of n-octanol, 4 parts of phenethyl alcohol and 4 parts of benzyl acetate.
Attractant 5: 1 part by weight of benzaldehyde, 1 part by weight of salicylaldehyde, 1 part by weight of n-heptaldehyde, 1 part by weight of n-octanol, 1 part by weight of phenethyl alcohol and 1 part by weight of benzyl acetate.
The test method comprises the following steps: the appropriate amount of the composition was placed in a slow release vial and placed in the field. The attracting test was conducted at the time of adult bollworms, and the attracting effect was examined 5 days later.
TABLE 3 attraction effect of different proportions of attractants on bollworm
| Formulation of | Luring amount (head) |
| Attractant 1 | 58 |
| Attractant 2 | 67 |
| Attractant 3 | 56 |
| Attractant 4 | 55 |
| Attractant 5 | 49 |
As can be seen from table 3, in the case of the same components, the ratio of the components in the composition will have a significant effect on the attracting effect, and the attracting effect of the attractant 2 is the best, attracting 67 bollworms.
The above description is not meant to be limiting, it being noted that: it will be apparent to those skilled in the art that various changes, modifications, additions and substitutions can be made without departing from the true scope of the invention, and these improvements and modifications should also be construed as within the scope of the invention.
