“…Our other sampling method involved tapping limbs in the canopy of host trees in the late afternoon to early evening hours as this is when adults tend to be present in host trees in greater numbers, particularly after bloom . However, it also readily infests cultivated Japanese and European plum cultivars (Quaintance & Jenne, 1912;Maier, 1990;Brown, 2005), with what appears to be a preference for Japanese plum based on our studies. In this case, adults had located and arrived within host tree canopies, but because this estimate was based on adults present in the tree at a particular moment, we do not know how long they had been there.…”

“…We found that significantly greater numbers of marked adults and the greatest number of wild adults were recovered from screen traps attached to Japanese plum compared to any other host (Table 3). The ancestral host of plum curculio is considered to be native species of plum found in North America (Quaintance & Jenne, 1912;Chapman, 1938), including P. americana (Quaintance & Jenne, 1912;Maier, 1990), P. hortulana Bailey (Quaintance & Jenne, 1912), P. angustifolia (Quaintance & Jenne, 1912;Jenkins et al, 2006), P. maritima Marsh (Maier, 1990), and P. umbellata Elliot (Jenkins et al, 2006). This technique provided a measure of the number of adults within a host tree canopy at a particular moment and indicated preference based on host-finding and/or acceptance [i.e., confirming the appropriateness of the plant after arrival (Bernays & Chapman, 1994)].…”

“…In the spring, adults move from overwintering sites toward orchards where they likely meet and mate in or near host fruit trees (Smith & Salkeld, 1964;Racette et al, 1992;Piñero et al, 2001). Adults feed on fruit buds and developing fruit, and females also oviposit in developing fruit soon after petal fall Chouinard et al, 1993), cutting a small, crescent-shaped flap in the fruit skin and then depositing an egg (Quaintance & Jenne, 1912;Chapman, 1938). Subsequent larval feeding can lead to either fruit drop (Levine & Hall, 1977) or severe scarring (Quaintance & Jenne, 1912;Racette et al, 1992).…”

We assessed host preference of adult plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), based on the total number of mark-released and wild adults recovered and the total distance moved by mark-released adults in an orchard whose layout was designed to specifically allow foraging plum curculios to choose among host tree species. Host trees included apple, Malus domestica Borkh.; pear, Pyrus communis (L.); peach, Prunus persica (L.) Batsch; apricot, Prunus armeniaca L.; tart cherry, Prunus cerasus L.; sweet cherry, Prunus avium (L.); European plum, Prunus domestica L.; and Japanese plum, Prunus salicina Lindl. (all Rosaceae). We released 2900 marked adults and recovered 17.7%. We used screen traps to provide a measure of the number of adults that arrived at and climbed up particular host trees and found that significantly greater numbers of marked adults and the greatest number of wild adults were recovered from screen traps attached to Japanese plum. We sampled host tree canopies by tapping limbs to provide a measure of the number of adults within a tree canopy at a particular moment. Again, significantly greater numbers of marked and wild adults were recovered from plum species, with no difference between Japanese and European plum cultivars for marked individuals, but with significantly greater numbers of wild individuals recovered from Japanese plum. The preference index (PI) for Japanese plum based on total distances moved by all marked adults recovered on Japanese plum divided by the total distance moved by marked adults recovered on other host trees indicated that Japanese plum was the most highly preferred host, followed by European plum, peach, sweet cherry, tart cherry, apricot, apple, and pear, respectively.

English SummaryField studies in southwestern Quebec showed that feeding scars of the plum curculio Conotrachelus nenuphar (Hbst.), were made by overwintered and summer adults and occurred throughout the growing season. Egg-laying scars were made by overwintered adults only and occurred from the time of apple set to early A o p t . The Iatter category included deep entries, which were made by the developing larvae in the fruit. In the McIntosh and Lawfam varieties feeding scars were found in 37.4 and 35.0 per cent respectively, averaging 36 per cent for the combined varieties, and egg-laying scars in 62.6 and 65.0 per cent, averaging 63.8 The extent of the two types of damage in the field appeared to be the reverse of those observed in the insectary, where feeding scars for the combined varieties averaged 63.2 per cent and egg-laying scars 36.8 per cent. In the insectary, 41.1 and 22.1 per cent of the feeding scars were respectively contributed by overwintered and summer adults. It was not possible to estimate these fractions in the field.On heavily infested Lawfam apple trees near woodland areas and lightly infested ones in the same orchard 70.3 and 56.8 per cent respectively of the apples dropped premameIy, the difference being statistically significant. Of the falen apples 26.8 per cent of the former and 3.9 per cent of the latter showed egg-laying scars. A similar comparison of heavily and lightly infested ~'McIntosh apple trees did not show significance between apples dropped prematurely and those showing egg-laying scars. This variety was markedly more resistant to plum curcnlio egg and larval development than the Lawlam variety. Since eggs were laid on apple of both varieties in approximately equal numbers, resistance appears to be t l~e result of tissue growth killing the eggs and hardness of tissue preventing the successful establishment in the fruit of newly emerged larvae.

Finding a suitable oviposition site can be a challenging task for phytophagous insects, particularly in areas with large temporal and spatial diversity of plant resources (Carrasco et al., 2015). To help narrow the search for an acceptable host, attraction and preference to hosts can be modulated by the experience of the insect. For instance, exposure to chemical cues during different stages of the insect's life can lead to a preference toward specific hosts (Anderson & Anton, 2014). Holometabolous adult insects gain experience of
