Table 4. Insect Damage Incidence 2014.
Oriental fruit moth (Grapholita molesta) monitoring consisted of two-four 100 fruit samples at each monitoring date (from a total of 15 peach varieties over the season) as fruit was developing (March-May) and at harvest (May-September). Average OFM damage across all peach varieties in 2014 occurred later in the season (late May-September) and was less than 3% of total fruit sampled.
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 Low (< 1%) and fruit damage caused by thrips during fruit development (April-May) and at harvest (late May-September) generally averaged less than 1%.
Aphid (Myzus persicae) monitoring consisted of 10 branches per sample. Aphids were only seen on pluots at a very low level.
Codling moth (Cydia pomonella) monitoring consisted of three-five 100 fruit samples at each monitoring date (from a total of 2 pear varieties and 13 apple varieties over the season) as fruit was developing (late March-May) and at harvest (June-September). Average CM damage across all pear and apple varieties in 2014 occurred mostly later in the season (late May-September) peaking at 8% of total fruit sampled in late August.
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). Fruit damage was very high, peaking at 30% and 14% in June. Cherries were not sprayed in 2014 due to a light crop.
