[0109] Indoor activity example

[0110] Example 1: indoor bioactivity test on lepidopterous pests

[0111] Test reference: the test refers to NY / T 1154.14-2008 "Pesticide indoor bioassay test guidelines insecticide part 14: leaf dipping method".

[0112] Test target: Plutella xylostella, Chilo suppressalis, Spodoptera exigua, Helicoverpa armigera, and the above target pests are selected as 3rd instar larvae;

[0113] Test agent: the compound of formula I, the flubendiamide, the tetraniliprole, the cyantraniliprole, the chlorantraniliprole, the chlorfenapyr, the cyhalofop-butyl, the sulfoxaflor, the tetraniliprole, and the flubrocythrinate technical material.

[0114] Agent preparation: the test agent is dissolved in a suitable solvent, then diluted with 0.1% Tween 80 aqueous solution, and 5 mass concentrations are set according to the activity of the agent.

[0115] Test method: fresh cabbage leaf discs (Plutella xylostella, Spodoptera exigua), corn leaves (Helicoverpa armigera), and wild rice shoots (Chilo suppressalis) are respectively immersed in the agent solution for 10s, then taken out and placed in a culture dish with filter paper, dried in the room, and then the corresponding larvae are introduced, 20 larvae per culture dish, and each treatment is repeated 4 times, and the corresponding organic solvent without the agent is set as a blank control. The treated test insects are placed in a temperature of (25±1)℃, a relative humidity of 60%-70%, and a light cycle of 16L:8D for feeding.

[0116] Investigation: Investigate the mortality of test insects 48 hours after treatment. Insects that are unable to crawl normally are considered dead, and the mortality rate is calculated.

[0117] Calculation method:

[0118] Based on the survey data, calculate the mortality rate of each treatment. Calculate as follows:

[0119]

[0120] Where:

[0121] P——mortality rate, in percentage (%);

[0122] K——indicates the number of dead insects, the unit is head;

[0123] N——represents the total number of insects processed, in heads.

[0124]

[0125] Where:

[0126] P1——adjusted mortality rate, in percentage (%);

[0127] P t ——Treatment mortality rate, expressed in percentage (%);

[0128] P0 - blank control mortality rate, in percentage (%).

[0129] If the control mortality rate is less than 5%, no correction is required; if the control mortality rate is between 5% and 20%, correction should be made according to the correction mortality formula; if the control mortality rate is greater than 20%, the test needs to be repeated.

[0130] The DPS statistical analysis system was used to analyze the toxicity regression equation, correlation coefficient and LC 50 The activity of the test agent on the biological test material is evaluated by the value.

[0131] The co-toxicity coefficient (CTC value) of the mixture is calculated as follows:

[0132]

[0133] Where:

[0134] ATI - measured toxicity index of mixture;

[0135] S——LC of standard acaricide 50 , the unit is milligrams per liter (mg / L);

[0136] M——LC of the mixture 50 , the unit is milligrams per liter (mg / L).

[0137] TTI=TI A ×P A +TI B ×P B

[0138] Where:

[0139] TTI – Theoretical Toxicity Index of Mixtures;

[0140] TI A ——Agent toxicity index;

[0141] P A ——The percentage of agent A in the mixture, in percentage (%);

[0142] TI B ——Toxicity index of agent B;

[0143] P B ——The percentage of agent B in the mixture, in percentage (%).

[0144]

[0145] Where:

[0146] CTC – Co-toxicity coefficient;

[0147] ATI - measured toxicity index of mixture;

[0148] TTI - Theoretical Toxicity Index of Mixture.

[0149] A co-toxicity coefficient (CTC) of 120 or higher indicates a synergistic effect; a co-toxicity coefficient (CTC) of 80 or lower indicates an antagonistic effect; and a co-toxicity coefficient (CTC) of 80 or lower indicates an additive effect.
