Indoor biological activity assay

Example 15 Determination of the synergistic effect of the composition containing tetrachlorantraniliprole on beet armyworm

Test object: beet armyworm (Spodoptera exigua), 3rd instar larvae, sensitive strains reared indoors.

Test conditions: temperature: 24～26℃, humidity: RH60%, light: L:D=14:10

Preparation method of the test drug solution: accurately weigh the active components tetrachlorantraniliprole, profenofos, chlorpyrifos, and triazophos in the insecticide of the present invention respectively with an electronic analytical balance, after adding an appropriate amount of acetone to the original drug to dissolve completely, Contain the water of 0.1% Tween 80 to be mixed with required concentration mother liquor, according to the ratio between two kinds of active components in the insecticide of the present invention, above-mentioned mother liquor is mixed in a certain proportion and is mixed with mixed solution, according to test design dose respectively Diluted into a series of liquid medicine with a certain concentration gradient.

Test method: adopt the artificial feed culture plate method, select a standard clean 24-well culture plate, add 1ml of artificial feed to each well, after cooling and solidifying, add 0.05ml of liquid medicine to each well of the culture plate with a continuous sampler, and then put it in the shade Naturally dry in the shade. The uniform test insects were selected and inserted into the culture plate, one head per well, and each treatment was repeated 4 times. Put the treated test insects in the observation room, observe the reaction of the test insects regularly, and investigate the number of dead and alive insects after 72 hours.

Abbott's formula was used to calculate the corrected mortality rate, and the Bliss method was used for evaluation, which is one of the classic methods for evaluating the effect of mixtures. According to the concept of independent joint action proposed by Bliss, the theoretical death rate P when pesticides are mixed can be calculated by the following formula:

P=P _m +P _n (1-P _m )

P _m is the death rate (%) of the target when the concentration of the first active component is m; P _n is the death rate (%) of the target when the concentration of the second active component is n.

If the actual death rate of the target after the two active components are mixed at a certain concentration is greater than the theoretical death rate P, it is judged that the mixed use of the two active components at the set concentration has a synergistic effect, otherwise it is an antagonistic effect.

The test results showed that the mixed use of tetrachlorantraniliprole, profenofos, chlorpyrifos and triazophos showed synergistic effect. The detailed results are shown in Table 1.
