FIELD: chemistry.
SUBSTANCE: invention describes compositions for use as a pest control agents containing a compound of formula (I), or a salt of the said compound, acceptable in agriculture or horticulture, as an active ingredient or carrier which is acceptable in agriculture or horticulture: 
[chemical formula 1] , where Het1 denotes an optionally substituted pyridyl, R1 denotes hydroxyl, optionally substituted C1-6alkylcarbonyloxy, optionally substituted C1-6alkyloxy, or oxo, in the absence of a hydrogen atom in position 13, or the bond between position 5 and position 13 is a double bond in the presence of R1 and a hydrogen atom in position 5, R2 denotes hydroxyl, optionally substituted C1-18alkylcarbonyloxy, benzoyloxy or C1-6alkylsulphonyloxy, R3 denotes a hydrogen atom, hydroxyl, optionally substituted C1-18alkylcarbonyloxy, benzoyloxy, C1-6alkylsulphonyloxy, benzoylsulphonyloxy, imidazolylthiocarbonyloxy, R4 denotes a hydrogen atom, hydroxyl, optionally substituted C1-18alkylcarbonyloxy, C2-6alkenylcarbonyloxy, C2-6alkynylcarbonyloxy, benzoyloxy, C1-6alkylsulphonyloxy, benzoylsulphonyloxy, benzyloxy, C1-6alkyloxy, C1-6alkyloxy-C1-6alkyloxy, C1-6alkylthio-C1-6alkyloxy, C1-6alkyloxy-C1-6alkyloxy-C1-6alkyloxy, C1-6alkyloxycarbonyloxy, C1-6alkylaminocarbonyloxy, tetrahydropyranyloxy, a saturated or unsaturated five- or six-member heterocyclic carbonyloxy, where the said heterocyclic part is selected from a group comprising pyridyl, thienyl, thiazolylpyrazinyl and imidazolyl, optionally substituted tieno[3,2-b]pyridylcarbonyloxy, 1H-indolylcarbonyloxy, imidazolylthiocarbonyloxy, or oxo, in the absence of a hydrogen atom in position 7, provided that the compound, where Het1 denotes 3-pyridyl, R1 denotes hydroxyl and each of R2, R3 and R4 is acetyloxy, is excluded. Disclosed composition is also used in hemipterous pest control.
EFFECT: synthesis of a novel pyripyropen having significant insecticide activity.
