“…Compared to several other field studies conducted using visual traps (Coli et al, 1985;Zijp, Blommers, 1997;Ciglar, Barić, 2002), sawfly trap catches were relatively low, reaching at most 33 sawflies trap -1 in 2010 in orchard with no pre-bloom insecticide applications. However, damage threshold of 30-40 apple sawflies per trap was determined by Wildbolz and Staub (1984) and yet in another study damage threshold of 30-40 sawfly trap -1 for apple cv.…”

“…In the cases when traps where heavily filled with other insects, they were replaced by the new ones. Around middle of June before the affected fruit drop on-tree fruit injury surveys were performed by visual examination of 50 (in 2010) or 100 fruits per tree selected at random from lower, central and upper parts of the tree canopy from 10 random trees per cultivar (Coli et al, 1985;Graf et al, 1996 b). In cultivars where fruit setting was too low and number of trees was limited all fruits from every tree were inspected.…”

“…The biology and behaviour of the apple sawfly have been intensively studied in the past in order to identify effective control strategies (Thomsen, 1929;Miles, 1932;Velbinger, 1939;Kuenen & van de Vrie, 1951;B6hm, 1952;Dicker, 1953;Chaboussou, 1961;Gottwald, 1982). More recently, monitoring meth-ods have been investigated (Wildbolz & Staub, 1984) focusing particularly on white sticky traps (Owens & Prokopy, 1978;Coli et aL, 1985;Wildbolz & Staub, 1986;Galli et al, 1993). It has been shown that exact timing is crucial for the success of control measures (H6hn et al, 1993).…”

The effect of temperature on post‐diapause development of the apple sawfly Hoplocampa testudinea Klug was studied under controlled conditions. Survival was found to decrease at temperatures higher than 15 °C, the lethal temperature being close to 25 °C. The lower thermal threshold was 4.5 °C; the values for males and females did not differ significantly. However, different values were established for unprotected individuals, in vermiculite and in potting compost respectively. Based on the overall mean and variance of the developmental time and the overall thermal threshold a simple soil temperature driven phenology model was constructed using a time‐ varying distributed delay. The validation with independent field and semi‐field data revealed the model to be a reliable tool to predict apple sawfly phenology and hence to determine the optimal time for the installation of white sticky traps or for control measures such as insecticide treatments.

“…On-tree fruit injury surveys were performed before fruitdrop by visual examination. Hundred (or 50 if fruit setting was low) fruits per tree were selected randomly from lower, central and upper parts of the tree canopy for damage assessment (500 fruits per cultivar in 2010 and 1000 fruits in 2011) (Coli et al, 1985;Graf et al, 1996b). Daily temperatures were recorded in soil at 10 cm depth and 150 cm above ground by an iMetos ® weather station (Pessl Instruments, Austria) located at the experimental apple orchard of the LRCAF Institute of Horticulture, ca.…”

The investigation of Hoplocampa minuta (Christ, 1791) (black plum sawfly), Hoplocampa flava (Linné, 1760) (yellow plum sawfly) and Hoplocampa testudinea (Klug, 1816) (apple sawfly) populations using white sticky traps Rebell®bianco was carried out in conventionally and organically managed apple and conventionally managed plum orchards of the Institute of Horticulture of Lithuanian Research Centre for Agriculture and Forestry in 2010 and 2011. Temperature sums for predicting sawfly spring emergence were determined: 120 ± 5 degree-days for apple sawfly, 85 ± 26 degree-days for black plum sawfly and 95 ± 28 degree-days for yellow plum sawfly. However, more years of the study are needed to confirm these temperature sums. The average densities of sawflies during the flight period were: H. minuta - 14.8 ± 7.3 sawfly trap-1 in 2010 and 54.2 ± 35.9 sawfly trap-1 in 2011; H. flava - 13.3 ± 5.2 sawfly trap-1 in 2010,and 16.6 ± 6.9 sawfly trap-1 in 2011; and H. testudinea in organic orchard - 38.3 ± 26.2 sawfly trap-1 in 2010 and 5.0 ± 2.8 sawfly trap-1 in 2011, in conventional orchard - 14.8 ± 8.1 sawfly trap-1 in 2010 and 9.3 ± 4.3 sawfly trap-1 in 2011. Conditions for development of both plum sawfly species were better in 2011, when abundance nearly reached the economic threshold. Population density, cumulative trap catches during the flight period, and damage caused by apple sawfly varied significantly between the study years and apple cultivars. In 2010, apple sawfly was more abundant and caused more serious damage than in 2011. The economic threshold of 30-40 individuals per trap was reached in 2010 due to the better conditions of development. The various apple cultivars suffered different damage levels: cv. ‘Aldas’, ‘Vitos’ and ‘Rubinola’ suffered the highest damage in the organic orchard, but no significant differences were observed. In the conventional garden, cv. ‘Auksis’ had the most damaged fruits.
