Problems solved by technology

However, tests have shown that daphnia and larvae are only sensitive to some pesticide activities, and other potential compounds with insecticidal activity cannot be screened out.
At present, the success rate of new pesticide development in the world is getting lower and lower, so the requirements for screening are higher
However, the current screening method inevitably misses the active compound.

Abstract

The invention relates to a pesticide biological activity testing method that uses Cyclops as acting object. In slight amount vessel, the sensitivity of the sample would be used to take insecticidal activity test by Cyclops. The method is easy to operate and is suited to test biology of slight amount sample. The method could be used to test the activity of the existing variety and research the new pesticides.

Description

technical field [0001] The invention belongs to the field of pesticide bioassay, and in particular relates to a pesticide bioactivity assay method using Crustacea as a test object. Background technique [0002] An important part in the research and development of new pesticides is the biological screening of new pesticides. With the deepening of research cognition and the continuous improvement of technical means, the inventory of test compounds is becoming more and more large, the source is diversified and the test samples are gradually microquantified. The test compound samples are not limited to chemical samples artificially synthesized in the laboratory. A large number of combined chemical samples, machine-automatically synthesized chemical samples, combined biochemical samples, microbial-derived compounds, and plant-derived compounds have also been added. The amount of these samples or synthetic samples is very small, or the active ingredient content is very low. Howe...
