Embodiment 2:
Of the present invention giving birth to surveyed experiment:
1, for the examination insect: 3 ages are armyworm larvae in earlier stage, is provided by insectary, Xibei Univ. of Agricultural ﹠ Forest Science ﹠ Technology public nuisance-free agricultural chemicals research centre.
2, sample and reagent:
Sample is: the compound 1-8 of Toosendanin, podophyllotoxin, 4-O-tetrahydropyrans podophyllotoxin, 4-O-tetrahydropyrans-2 β-chloro podophyllotoxin, 2 β-chloro podophyllotoxin and embodiment 1 preparation.Solvent is an acetone, the Long Huagongshijichang of Chengdu section, analytical pure.
3, give birth to the survey method:
Adopt leaflet butterfly additive process: at diameter is shop, culture dish bottom one deck filter paper of 9 centimetres, and adds water and preserve moisture.The armyworm larvae in early stage in 3 ages that 10 sizes of every ware picking are consistent, healthy and strong.Take by weighing 5mg Toosendanin, podophyllotoxin, 4-O-tetrahydropyrans podophyllotoxin, 4-O-tetrahydropyrans-2 β-chloro podophyllotoxin, 2 β-chloro podophyllotoxin and compound 1-8 respectively, add 5ml acetone, be made into the soup that concentration is 1mg/ml.Leaf of Semen Maydis is cut into 1 * 1 centimetre little leaf butterfly, in soup to be measured, soaked 3 seconds, dry the back and feed the examination worm.With the acetone solution is the blank group.10 of every processing repeat 3 times.In under the room temperature (about 25 ℃), humidity 65%～80%, light application time is to raise under 12 hours/day the condition.Feed with normal leaf butterfly until emergence after 48 hours.The food ingestion of periodic logging insect, survivor of a murder attempt's number, reveal any symptoms etc. calculate examination 24 hours, 48 hours food refusal rate of worm and final mortality ratio according to following formula.Measurement result sees Table 1.
Food refusal rate (%)=(the average food ingestion of the average food ingestion-treatment group of control group)/(the average food ingestion of control group) * 100
Final mortality ratio (%)=(the dead number of examination worm)/(the total number of examination worm) * 100
Correct mortality ratio (%)=(handling mortality ratio-contrast mortality ratio)/(1-contrasts mortality ratio) * 100
Table 1 the present invention 2 β-chlorine podophyllotoxin derivative 1-8 to 3 age mythimna separata the food refusal toxic effect
Conclusion: the result shows, the compound 2 of the present invention's preparation, and the antifeedant activity 24 hours and 48 hours all is higher than podophyllotoxin, and the cytotoxicity of compound 1,3,7 all is higher than Toosendanin and parent compound, can be as the application for preparing plant insecticide.
