Host specificity of the rubber vine moth, Euclasta whalleyi Popescu-Gorj and Constantinescu (Lepidoptera: Crambidae: Pyraustinae): field host-range compared to that predicted by laboratory tests
The moth Euclasta whalleyi was introduced into Australia in 1988 for the biocontrol of its host plant, rubber vine Cryptostegia grandiflora, despite test results predicting it might also attack the related native vine Gymnanthera oblonga. Ten years after release, the moth is widespread and damaging on rubber vine, but there is no attack on G. oblonga, except when it is growing in close association with rubber vine plants. The implications of ‘false positives’ in host-specificity testing are discussed.
