Pollen availability for predaceous mites on apple: spatial and temporal heterogeneity

  title={Pollen availability for predaceous mites on apple: spatial and temporal heterogeneity},
  author={Jason A Addison and John Michael Hardman and Sandra Wilde},
  journal={Experimental & Applied Acarology},
It has been suggested that an abundance of alternate food early in the spring may be critical to the ability of generalist predaceous mites to suppress spider mite pests. One alternate food that is typically very abundant in spring is wind-dispersed pollen. Here we investigate, at several spatial scales, the heterogeneity in the availability of pollen to predaceous mites on apple. We found pollen to be abundant on apple leaves very soon after they opened (>100 grains/cm 2 ), and that the… CONTINUE READING
