摘要

Twenty two species of grain legumes from four genera that are important or potentially important to Australian agriculture were examined for their response to feeding by redlegged earth mite (Halotydeus destructor) under controlled conditions. Special attention was paid to differences among species within a genus. Plants were exposed to mites at the seedling stage and feeding damage scored one week and two weeks after mite application. The results showed that within the genus Lupinus, lines of yellow lupin (L. luteus) had the highest feeding scores, while rnites fed less on lines from narrow-leafed lupin (L. angustifotius). Lines from albus lupin (L. albus) and rough seeded lupins (L. atlanticus, L cosentini, L. pilosus) suffered minimal attack bymites. H. destructor feeding damage also differed between species from the genus Vicia. V. sativa was attacked most, while V. ervillia and V. articulata were fed on very little, Five species from Lathyrus differed in levels of H. destructor feeding damage. L. tingitanus and L. ochrus were fed on most. L. ocero and L sativus were fed on very little. Species and subspecies from Pisum were readily damaged by H. destructor feeding, with no significant variation among them. It is unlikely that the same mechanisms cause resistance to H. destructor over such a range of species. Mite feeding was clearly affected by interspecific variation within genera. A better knowledge of the mechanisms involved will assist selection and breeding of crops showing resistance to this pest.
