The celastrus angulatus is an extract of celastrus angulatus root bark of a wild shrub plant of Celastraceae, and belongs to a botanical pesticide. In recent years, researches show that the celastrus angulatus has the effects of anesthesia, food refusal, stomach toxicity and contact poisoning, and has the characteristics of no drug resistance, no natural enemies killing, stable physicochemical properties and the like. The insecticidal mechanism mainly acts on the alimentary canal tissues of insects to destroy the normal functions of the alimentary canal systems of the insects, so that the insects are difficult to feed and die due to hunger, and the insecticidal composition has high efficiency on partial lepidoptera, orthoptera and coleoptera pests, such as lepidoptera larvae, aphids and the like, and has good control effect; the pesticide has higher food refusal to aphids, armyworms, whiteflies, plant hoppers and cabbage caterpillars; has high stomach poisoning effect on field pests such as cabbage looper, cotton bollworm and the like.

Drying and screening to obtain the 60 percent dicyclopropyl caterpillar ester celangulin water dispersible granule.
Second, biological test
Example 1: indoor toxicity determination of compounded dicentra propinqua and celastrus angulatus on rice stem borer
The test method comprises the following steps: the measurement was carried out by the dipping method. The drugs to be tested are pre-dissolved in acetone respectively to prepare 1% mother liquor, and a preliminary test is firstly carried out. The mother liquor was then diluted into 5 concentration gradient solutions for use, 3 replicates per treatment set, 20 larvae per replicate, and the larvae were concentrated in the impregnator. Soaking the liquid medicine for 5s, transferring to a culture dish filled with fresh rice stalks, placing into a constant temperature incubator for culture, checking the number of dead insects after 48h, counting the death rate of larvae in each culture dish, taking the death rate as a toxicity regression curve, and calculating the EC50 value. And finally, calculating the co-toxicity coefficient (CTC) according to the Sun Yunpei method. When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
Observed virulence index (ATI) ═ standard agent EC 50/test agent EC50 × 100
Theoretical virulence index (TTI) ═ A percent virulence index × of agent(s) and + B percent virulence index × of agent(s)
The cotoxicity coefficient (CTC) ═ × 100 [ measured virulence index (ATI)/theoretical virulence index (TTI) of the mixture ].
TABLE 1 indoor toxicity assay of Dicyclobutrin and Celastrus angulatus against Rice-stem borer
As can be seen from Table 1, when the weight ratio of the active ingredients of the biopesticide, namely the dicyclaniliprole and the celastrol is 1:15-20:1, the CTC value is more than 120, and the biopesticide has synergistic effect on rice stem borer; when the weight ratio of the dicyclopropanate to the celastrus angulatus is 1:1-10:1 or 1:10, the CTC value is larger than 130, and the remarkable synergistic effect is shown.
Example 2: field control effect of compounded dicentrazon and celastrus angulatus on brown planthopper of rice
Test subjects: nilaparvata lugens (Piperaceae)
The test method comprises the following steps: the test is carried out according to the national standard GB/T17980.4-2000 of 'pesticide field efficacy test rule (I) for controlling rice planthopper by using pesticide'. Each treatment was repeated 4 times, cell area 30m2The method comprises the steps of randomly arranging blocks, protecting rows with the width of 0.5m among the cells, carrying out spraying treatment on 2-instar and 3-instar nymphs of the brown planthoppers in the full-fleshed period, surveying 10 points and 2 groups in each cell by a parallel jumping method, surveying 20 groups in each point, brushing a layer of engine oil on a white porcelain plate with the length of 40cm × 30cm, obliquely placing the white porcelain plate on the middle lower part of the rice, quickly beating the rice plant 2, quickly surveying and counting the number of the brown planthoppers, surveying the population base number before pesticide application, sampling 7 days after pesticide application according to the same surveying method, surveying the number of residual live insects, counting the number of residual insects in a hundred holes, observing the safety of a test medicament on crops, and calculating the population decline rate and the correction control effect of each treatment area according to the surveying result.
The calculation formula is as follows:
the oral cavity decline rate is (number of live insects before treatment-number of live insects after treatment)/number of live insects before treatment) × 100%
The correction control effect is (the reduction rate of the population of the medicament treatment area-the reduction rate of the population of the blank control area)/(the reduction rate of the population of the 1-the blank control area) ] × 100%
TABLE 2 field control of nilaparvata lugens by combinations of dicentrazofamid and celastrus angulatus
As can be seen from table 2, compared with the single use, the combination of the biopesticide components of the diproprionate and the celastrus angulatus can obviously improve the control effect of the biopesticide components on the brown planthopper of the rice, and has obvious synergistic effect; can slow down the generation of resistance, has good safety to rice and meets the safety requirement of pesticide preparations.
The present invention has been further described with reference to the examples, but the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
