The present invention provides compounds of the general formula: ##STR1## wherein R.sub.1 is a hydroxyl group or an acyl radical of a straight-chained or branched, saturated or, when R.sub.2 is an acyl radical other than an acetyl radical and/or R.sub.4 is a hydrogen atom and/or R.sub.5 is a hydrogen atom or an alkoxy radical, unsaturated monocarboxylic acid containing up to 10 carbon atoms, R.sub.2 is a hydroxyl group or an acyl radical of a straight-chained or branched, saturated or, when R.sub.1 is an acyl radical and/or R.sub.4 is a hydroxyl group and/or R.sub.5 is a hydrogen atom or an alkoxy radical, unsaturated monocarboxylic acid containing up to 10 carbon atoms, R.sub.3 is an acetyl or methyl radical, R.sub.4 is a hydrogen atom, a hydroxyl group or an acetyl radical and R.sub.5 is a hydrogen atom, an alkoxy radical containing up to 6 carbon atoms (not only in the .alpha.- but also in the .beta.-position) or an additional bond to C22. The present invention also provides insect-destroying agents containing these compounds.
Azadirachtin F of the formula ##STR11## in which Tig represents tigloyl.
An insect-destroying agent comprising, as active material azadirachtin F of the formula ##STR12## in which Tig represents tigloyl, and a carrier
A method for combatting insects which comprises applying to said insects in their developing stages, in sufficient amount to disturb their growth, azadirachtin F of the formula ##STR13## in which Tig represents tigloyl.
