“…T. setifer has been reported previously from alfalfa. It was noted as being heavy in alfalfa in California (Anonymous 1968) and was collected on old alfalfa stems from mature or old growth in the Imperial and Bard valleys of California by Lehman and Flock (1970). It was believed this tarsonemid was feeding on a sooty mold growing on honeydew produced by the spotted alfalfa aphid.…”

Observations were made during 1967 to 1969 at Ithaca, N.Y., supplemented by collections at New Cumberland and Carlisle, Pa., on arthropods associated with fungi occurring on alfalfa, Medicago saliva L. Five species of Coleoptera, two species of Diptera, one species each of Collembola and Psocoptera, and nine species of Acari were reared or collected consistently from fungus-covered alfalfa leaves, stems, and seed pods. Attraction to fungi on the plants, principally Alternaria sp., accounted for the presence on alfalfa of arthropod species that normally might be considered as accidentals or visitors. The mycetophagous species thus contributed to the richness of the alfalfa fauna. Immature stages of several species were collected only in late fall or on 3- or 4-year-old plants. The possible role of the fungus-feeding species in seasonal changes in the alfalfa fauna and changes in the fauna in successive years is discussed.

Canonical variates analysis was adapted to the problem of classifying environments according to their interactions with wheat genotypes, and was used to subdivide the Central West of New South Wales into uniform sub-regions. The method takes into account any fluctuations from year to year in the genotype x location interaction effects, and has several other advantages over the procedures previously used. Most of the variability among locations was represented by one canonical variate and was related to an east-westerly trend. It is suggested that the Central West be divided into two sub-regions, the eastern slopes and the western plains, for the purpose of varietal evaluations and recommendations.
