Abstract
Synthetic derivatives or intermediates of xylomollin are identified which can be used as insect feeding deterrents. The identified derivatives or intermediates exhibiting antifeeding activity include glutaraldehyde and carbocyclic or heterocyclic dialdehydes wherein the aldehyde groups are positioned on adjacent carbons of the carbocyclic or heterocyclic rings. The active compounds also include the hemiacetal hemiacetal equivalents, the acetal hemiacetal equivalents and the vinyl ether equivalents of the dialdehydes.
Claims42
A method of deterring the feeding activity of insects on plant and crop material comprising the step of applying an insect antifeedant effective amount of an active compound of the formula:
- ##STR11## wherein ring B is a 5 or 6 carbon ring, or a lactone, that may include an alkene function and R.sub.1 is H, OH or an alkyl, R.sub.2 is H, OH or an alkyl and R.sub.3 is H or an alkyl.
A method of deterring the feeding activity of insects on plant and crop material comprising the step of applying an insect antifeedant effective amount of an active compound of the formula:
- wherein ring B is a 5 or 6 carbon ring, or a lactone, that may include an alkene function and R.sub.1 is H, OH or an alkyl, R.sub.2 is H, OH or an alkyl, R.sub.3 is H or an alkyl and R.sub.4 is H or an alkyl, and at least one of R.sub.3 and R.sub.4 must be H.
A method of deterring the feeding activity of insects on plant and crop material comprising the step of applying an insect antifeedant effective amount of an active compound of the formula:
- ##STR17## wherein R.sub.1 is H or an alkyl.
