Table 3. Insect Damage Incidence 2013 (%)

  1. Oriental fruit moth (Grapholita molesta) monitoring consisted of two-four 100 fruit samples at each monitoring date (from a total of 12 peach varieties over the season) as fruit was developing (March-May) and at harvest (May-September). Average OFM damage across all peach varieties in 2013 occurred later in the season (late May-September) and was less than 2% of total fruit sampled.
  2. Western flower thrips (Frankliniella occidentalis) monitoring consisted of both branch (10/sample) and fruit (100/sample) samples. Thrips population density in spring branch samples (March) was relatively high, peaking at 11.6% infested branches. Nonetheless, fruit damage caused by thrips during fruit development (April-May) and at harvest (late May-September) averaged less than 2%.
  3. Aphid (Myzus persicae) monitoring consisted of 10 branches per sample. Aphids were only seen on pluots at a very low level.
  4. Codling moth (Cydia pomonella) monitoring consisted of three-five 100 fruit samples at each monitoring date (from a total of 3 pear varieties and 8 apple varieties over the season) as fruit was developing (March-May) and at harvest (June-September). Average CM damage across all pear and apple varieties in 2013 occured mostly later in the season (late May-September) peaking at 9% of total fruit sampled in late August and 8% in September.
  5. Spotted wing drosophila (Drosophila suzukii) monitoring consisted of two 100 fruit samples at each monitoring date (from a total of 2 cherry varieties) at harvest (May-July).
