The study of the biological activity of the proposed compounds.
Studying the effect of collision on a housefly.
The insects of interest are domestic flies of 4-day-old females. Operate directly by spraying at a concentration of the active substance of 0.25 g / l in the Kern and Marsh chambers, using as a solvent a mixture of acetone (5%) and isopara L (a test solvent). Apply a solvent in the amount of 2 ml / s. 50 insects are used per treatment. A control is made every minute for 10 minutes, and then for 15 minutes, and 5 kg of so are determined by conventional methods.

Study of the lethal effect on the housefly
The insects studied are domestic flies of females at the age of 4-5 days. They act by topically applying 1 µl of the acetone solution on the dorsal thorax of insects using an Arnold micromanipulator. It consumes 50 fish per treatment. Mortality control was performed 24 hours after treatment
The results, expressed in DLpo, or the dose (in nanograms) per individual, necessary to kill 50% of the insects, are given below:

Study of lethal effect on Spodoptera hittoralis larvae
Samples are topically applied with an acetone solution using an Arnold micromanipulator to the dorsal thorax of the larvae. 15 larvae per dose of test product are consumed. The larvae consumed are the larvae of the fourth larval stage, i.e. at the age of about 10 days, when they are diluted at 24 ° C and 65% relative humidity. After processing, individuals are placed on an artificial nutrient medium (Poitou medium).
Mortality control is done 48 hours after treatment.

individuals of ticks at the rate of 15 individuals on each side of the sheet, i.e. 30 individuals per dose. Use 5 doses of the product at the rate of 250-5000 mg / hl.
The activity of the products is checked after 3 days. The experiments were carried out at a constant artificial light of about 200 lux at 22 ± + 1 C and at a relative humidity of 60 ± 5%.
The deadly effect is determined by the number of dead ticks found on or near the sheet, and the repulsion effect by the number of live ticks found near the sheet.
The total effect is the sum of two effects (lethal effect + repulsive effect) and corresponds to the overall effectiveness of the product in question.
The result is expressed in the minimum dose resulting in at least a total efficacy of 99% after 3 days.
The compound of Example 8 is minimal mg / gly on the leaves of Tetrauychus urticae and Panonychus citri.
The results of the comparative tests of the products obtained according to the method of the invention.
The product X indicated in the tests below is 1R, the cis 2,2-dimethyl-3- (2,2-dibromovinyl) cyclopropane-1-carboxylate SL-cyano-3-phenoxybenzyl described in French patents nos. 2240914 and 2185612.
In order to determine the relative magnitude of the activity of these products in tests of this kind, this value is expressed in units of relative power (P), which is set as follows.
The effect of collision () for each of the compounds is determined (results are shown below). The relative power P is defined as the ratio between the time required to kill 50% of insects treated with known product X (i.e., K50) and the time required to kill 50% of insects treated with the product being studied (KT50) is expressed in minutes .
