摘要
Tyrophagus curvipenis Fain & Fauvel, 1993 (Acari: Acaridae) has been reported from a very broad range of plant and animal hosts in various habitats in Australia, France, Portugal and New Zealand. However, except host/habitat records, there have been no reports of its life history and other aspects of biology. In this laboratory study conducted at 25 degrees C, T. curvipenis were kept individually and fed three different diets. The time from egg to adult mite was recorded and size of resulting adult mites was measured. T. curvipenis completed development on dry yeast in 10 days, about half of time needed when fed rolled oats and 42% of time needed when fed wheat flour. The length and width of the prodorsal shield was used to determine adult size. Adult females fed yeast were 18% larger than those fed on oats and 25% larger than those fed on wheat flour. Adult males were 14% larger on yeast than on oats, and 27% larger on yeast than on wheat flour. Faster development and larger size at maturity on yeast are correlated with the higher protein content of yeast compared to that in oats and wheat. Males were smaller and developed faster than females on all three diets.
