To the resulting clear solution was then added drip. l m 15 g (0.046 mol) of 1- (4- $ enilmercapt-feioxy) -propyl bromide and the mixture is stirred for 4 hours at room temperature. For the purpose of treatment, the reaction mixture is boiled into water and extracted with diethyl ether. The ether solution is washed twice with 10% potassium hydroxide solution and immediately thereafter three times with a saturated sodium chloride solution. After drying the ether solution over sodium sulfate, the solvent is distilled off in a vacuum; ,,.;;:, ..:

The forms of the preyrates of the renewed compounds are: dusty, granules, wettable nopbtliia-f, emulsions.

The content of the active site is from 0.1 to 95% by weight. %

A Contact action on pupae Pr, ..:, -. ; , .. i.r.; .-. ii, .. ::. i with ,;

pegyou molitor .;

A certain amount of a 0.1% solution of the biologically active substance in acetone, corresponding to the amount of birles of the logically active substance 10 mg / m, is introduced with a net into the aluminum bag and distributed raviomerically. After evaporation of the acetone, 10 newly grown pupae of Fenebrio molitor are placed on the treated surface. The cup is then closed with a lattice lid.

After untreated control animals have left the shell of the pupae as adults, which developed from the above-treated Pupae of the test animals, they are examined for the number of normally developed adults.

B. Contact action on the larvae of Dysercus fasciatus.

A certain amount of a 0.1% solution of the biologically active substance in acetone, 10 mg / m corresponding to the amount of the biolotically active substance, is brought into the aluminum cup and evenly distributed. After evaporation of the acetone on the treated surface of the cup, which contains feed and wet

cotton wool, place 10 larvae at the 5th stage of Dysercus fasciatus. The cup is then closed with a cross-colored lid.

After about 10 days, i.e., as soon as untreated control animals go through the molting process and become adults, developed from the treated individuals, tested animals and animals do not follow the ratio of the number of normal adults.

B. Effect on Spodoptera littoralis (ha):

Spodoptera littoralis eggs are immersed in a 0.05% solution of biologically active

substances in a mixture of acetone and water (1: 1). Thus, the treated eggs of the venture are removed from this mixture and at 21 ° C and with a cleanliness ™ 60% of the mixture is placed in plastic cups; After 3-4 days, the amount of TRIPPED LIVELY, t. The number of lychikb kotorii developed from processed eggs.

G. Action on the Aedes aeg5pty- grub. Using a pipette, such an amount of a 0.1% solution of the biologically active substance is placed on the surface of 150 ml of water in a glass that the concentrations of the biologically active substance are 10.5 and 1 ppm. the active substance of the glass is placed at 30-40 at the age of 3 days of the larvae of Aedes aegypty. Apply two glasses per concentration. Bio-Insecticidal Activity

Best of the world ,; .: ..: i

After 1, 2 and 5 days, they are assessed for possible death. Then attention is paid to interference with the pupation, metamorphosis and molting of adult animals.

The following compounds are tested. The obtained insecticidal activity values correspond to the evaluation scheme of the described tests A – D, presented in the table.

Thus, the compounds according to formula 15 have a high insecticidal activity. STI, the eye contains a compound of general formula as ether derivatives
