FIELD: chemistry. n SUBSTANCE: invention relates to a heterocyclic derivative of nicotine with an oxo-bridge, selected from compounds having the structure described by formula (A) or (B), or an optical isomer thereof: n , n where R 1 is a nitrogen-, oxygen- and/or sulphur-containing five- or six-member heterocycle; a halogenated nitrogen-, oxygen- and/or sulphur-containing five- or six-member heterocycle; or a substituted or unsubstituted phenyl, where the substitute is a halogen; R 3 and R 4 together form -CH 2 -CH 2 - or -CH 2 -CH 2 -CH 2 -; R 5 , R 6 , R 7 , R 8 and R 9 are hydrogen; and Y is nitro. The invention also discloses pest control agrochemical compositions which contain said compounds. n EFFECT: obtaining novel compounds of said formulae, which can be used in agriculture for controlling various pests, including homopterous and lepidopterous pests, such as aphids, lantern flies, whiteflies, cicadae, most thrips, cotton bollworms, cabbage worms, cabbage moth, cotton worms and caterpillars. n 20 cl, 2 tbl, 13 ex |
