Insect Hormone Activity of p -(1,5-Dimethylhexyl)benzoic Acid Derivatives in Dysdercus species

Derivatives of p-(1,5-dimethylhexyl)benzoic acid are juvenile hormone analogs with selective action on the hemipteran insects of the family Pyrrhocoridae. Their juvenile hormone activity is constant on five species of Dysdercus; it is about ten times lower on Pyrrhocoris, and no activity has been detected on hemipterans of some other families. Absence of profound species-specific variations in the activity suggests that the most active compounds of this type can be used as selective pesticides against all species of Dysdercus.
