Compounds of formula (I) <CHEM> wherein R represents a hydrogen atom or a silyl group; R<1> represents a methyl, ethyl or isopropyl group; Y<1> is -CH2-, Y<2> is -CH- and X represents -C(R<2>)(R<3>)-[where R<2> represents a hydrogen atom or a group OR<6> (where OR<6> is a hydroxy group or a substituted hydroxyl group having up to 25 carbon atoms) and R<3> represents a hydrogen atom, or R<2> and R<3> together with the carbon atom to which they are attached represents @C=O, @C=CH2 or@C=NOR<7> (where R<7> represents a hydrogen atom or a C1-8 alkyl group and the group @C=NOR<7> is in the E configuration)] or -Y<1>-X-Y<2>- represents -CH=CH-CH- or -CH2-C=C-; R<4> represents a group OR<6> as defined above and R<5> represents a hydrogen atom or R<4> and R<5> together with the carbon atom to which they are attached represents @C=O. These compounds may be used for controlling insect, acarine, nematode or other pests. |
