Detailed Description
The present invention will be further described with reference to the following examples.
Structural formula of Eurycomaldone
Eurycomaldone is also called eastern leather lactone, and the molecular formula is C19H24O6The compound is a compound separated from Eurycomolongifolia of a plant Eurycoma longifolia.
Example 1 Eurycomaldone can be absorbed into the root via the root of the heart of the cabbage and transported up the leaf to make insects resistant to eating the leaf of the heart of the cabbage
The method comprises the following steps: dissolving Eurycomaldone in DMSO to obtain 10000 μ g/mL mother solution, and adding 0.5mM CaCl2The mother liquor was diluted to 100. mu.g/mL of culture broth with the aqueous solution. The previously cultivated untreated cabbage heart seedlings (6 leaf stage) were placed in 0.5mM CaCl2After 2 hours of pre-culture in the aqueous solution, the extract is transferred into the prepared 100 mu g/mL Eumycotachlone culture solution, 0.7 g of leaf blades at the top end of the flowering cabbage are taken after 24 hours of culture, the crushed extract is dissolved in 2mL of methanol, and the extract can be detected to contain the Eumycotachlone by a liquid chromatography-mass spectrometer. The content of Eurycomaldone in the apical leaves (fresh leaves) of the heart was calculated to be 32. mu.g/g. The leaf blade at the top of the cabbage heart absorbed with the Eurycomaldone is beaten into a circular leaf disc with the diameter of 1.2 cm, and then inoculated with the 3 rd larva of the diamondback moth, and the process is repeated for 3 times. At a relative humidity of 50-70% and a temperatureKeeping the temperature of the mixture at 25-28 ℃ for 24 hours, then counting the food intake area, and calculating the food intake rate and the food refusal rate.
The eating rate calculation formula is as follows:
the food refusal rate is calculated by the formula:
as a result: the Eurycomaldone has good systemic characteristics on plants, the antifeedant activity of the Eurycomaldone on plutella xylostella is detected by a butterfly method, the Eurycomaldone has obvious effect, and the antifeedant rate of the plutella xylostella is higher than 80.1% after the plant is cultured for 48 hours in a culture solution containing the Eurycomaldone, so the Eurycomaldone can be used as a good root-irrigation biological pesticide, has high antifeedant activity on insects, and can achieve the effect of preventing and controlling plant diseases and insect pests.
Example 2: inhibition of cell proliferation of plutella xylostella and prodenia litura by eurycollactone
The method is characterized by exploring whether Eurycomaldone has an inhibition effect on proliferation of diamondback moth embryonic cells and prodenia litura ovarian cells or not, detecting the cell proliferation inhibition rate by adopting a CCK-8 method, and the results are shown in Table 1:
TABLE 1 proliferation inhibition rate of Eurycomaldone on insect cells
And (4) experimental conclusion: as can be seen from Table 1, Eurycomaldone has a significant inhibitory effect on the proliferation of insect cells, and is positively correlated with the concentration of Eurycomaldone. The inhibition rate of the Eurycomaldone with different concentrations on the spodoptera litura ovarian cells is more than 61%; the Eurycomaldone also has strong inhibition effect on diamondback moth embryonic cells; the sensitivity of the Euryomalactione to diamondback moth embryonic cells is lower than that of prodenia litura ovarian cells; under the condition that the experimental concentration is more than 12.5 mu g/mL, the inhibition rate of the Eurycomaldone on two insect cells is more than 50 percent.
Example 3: antifeedant activity of eurycollactones against insects
The method comprises the following steps: the method comprises the steps of dissolving Eurycomaldone in acetone to prepare a mother solution of 2000 mu g/mL, diluting the mother solution with acetone to obtain liquid medicines of 5 mu g/mL, 10 mu g/mL and 20 mu g/mL, uniformly coating the liquid medicines on the surfaces of round cabbage leaf disks with the diameter of 1.5 cm, coating the liquid medicines on each leaf disk to be 20 mu L, naturally drying the acetone on the surfaces of the leaf disks, inoculating Plutella xylostella (Linnaeus) 3-year-old primary larvae, repeating treatment for 3 times per concentration, counting the feeding area after keeping the temperature for 24 hours in an environment with the relative humidity of 50-70% and the temperature of 25-28 ℃, and calculating the feeding rate and the food refusal rate, wherein the calculation formula is shown in example 1.
Cassava leaf for testing antifeedant activity of Eurycomaldone against Spodopteritaura (Fabricius)1 st instar larvae; amaranth leaf for testing antifeedant activity of eurycomaldone against 1 st instar end larvae of spodopteragegus exigua (hubner); when the antifeedant activity of the Eurycomaldone on the aphid Lipophiseryimi is tested, the leaf of the cabbage heart is used, and other processing methods and calculation methods are the same as those of the 3 rd larva of the diamondback moth.
TABLE 2 antifeedant Activity of Eurycomaldone against insect larvae (48 h after treatment)
TABLE 3 antifeedant concentrations of Eurycomaldone and Azadirachtin (Azadirachtin) against insects
As a result: after the eurycomaldone is treated for 48 hours, the antifeedant rate of the insects is shown in tables 2 and 3, and the eurycomaldone has antifeedant activity to different degrees on asparagus caterpillar, diamond back moth, prodenia litura and cabbage aphid; the antifeedant concentration of the Eurycomaldone to the beet armyworm is 18.76 mu g/g, which is lower than that of the Azadirachtin in a control group; antifeedant effect of eurycolatone on insects under the same conditions: the cabbage aphid, beet armyworm, prodenia litura and diamond back moth show higher antifeedant activity.
Example 4: the compound has inhibitory activity on insect growth
The method comprises the following steps: adding Eurycomalactone with the concentration of 10 mug/g into the feed, and feeding insects for 48h, wherein the plutella xylostella is 3-instar middle-stage larvae, and the beet armyworm is 2-instar later-stage larvae; feeding normal feed to a control group; sampling and detecting the weight of the insect after feeding for 48 hours; and (4) feeding the 3 rd instar diamondback moth larvae for 8 days, and feeding the 2 nd instar beet armyworm larvae for 10 days, and then calculating the pupation rate.
TABLE 4 influence of Eurycomaldone on insect growth and development
TABLE 5 influence of Eurycomaldone on the pupation Rate of insects
As a result: as shown in tables 4 and 5, Eurycomalactone has obvious growth inhibition on diamond back moth and beet armyworm, and the weight of the single insect is reduced by 0.011 g-0.015 g compared with the control group. Compared with the control group, the pupation rate of the plutella xylostella and the beet armyworm after eating the Eurycollactone is obviously lower than that of the control group.
