n African Entomology - The host range of , an insect considered for the biological control of in Australia




The geometrid caterpillar was imported from Kenya into quarantine facilities in Australia as a potential biological control agent for prickly acacia, subsp. (Benth.) Brenan (family Mimosaceae). The insect was then tested on 30 plant species presented to neonate larvae as a no-choice cut foliage test and 13 plant species presented as a no-choice potted plant test. In these tests the insect was able to complete its life cycle on 13 native spp. and also on and the exotic ornamental (family Caesalpiniaceae). The tests supported field observations that the insect has a host range spanning many leguminous species and as such the insect could not be considered for release in Australia.
