Malusspp. recorded as uninfested by leafminers by Pottinger and LeRoux (1971) were exposed to oviposition byPhyllonorycter crataegella(Clemens) in choice and no-choice tests in the laboratory. Leafminers were able to complete their development from egg to adult on all selections screened. ‘Macspur’ was consistently one of the most susceptible varieties whileM. fuscaF-19 was consistently one of the least susceptible, apparently through nonpreference for oviposition. Other selections did not show consistent levels of resistance in both choice and no-choice situations.
