Abstract
Groups of the two Italian termites Kalotermes flavicollis and Reticulitermes lucifugus were exposed to different concentrations of the Insect Growth Regulator fenoxycarb. Results showed a marked juvenile hormone analogue activity, since the substance induced, on both species, an abnormal appearance of intercastes. On K. flavicollis, fenoxycarb inhibited the differentiation to neotenic reproductives, but did not prevent larval moults. Caste unbalances induced by this IGR can cause a progressive weakening of termite colonies until extinction.
