“…A number of studies investigating weevil attack on acorns have shown lower rates of infestation during years of high acorn production35. For example, 66% of Q. liaotungensis (a variety of Q. mongolica )16 and 86% of chestnut oak acorns20 were attacked by weevils during years of lower acorn production and only 29% and 26% in high production years. Indeed, a negative correlation between seed crop size and predation rate by seed insects has been reported for many temperate tree species9.…”

“…Weevils are one of the major causes of declining regeneration of Quercus spp. in northwestern India18 and have been reported to infest or destroy up to 70% of acorns of Q. crispula in Japan9, and >90% of acorns in eastern hardwood forests in the US1920. Despite the dominance and importance of Q. schottkyana to the integrity of these southern Chinese forests and the region’s biodiversity, few studies have reported acorn production and rates of weevil infestation by any of the oak species in the subgenus Cyclobalanopsis 1521 and their data are only for 1 or 2 years.…”

“…The oaks ( Quercus spp. ), distributed widely throughout the world (Johnson, Shifley, & Rogers, ; Struve, Sternberg, Drunasky, Bresko, & Gonzalez, ), often suffer from a lack of seedling recruitment due, in part, to extensive acorn predation (Lombardo & McCarthy, ; Macdougall et al, ). Due to their large size (1–13 g) and high energy content (Perea, Fernandes, & Dirzo, ), the acorns of oaks are a preferred food source for numerous vertebrate species (Haas & Heske, ; Leiva & Fernández‐Alés, ; Sundaram, Lichti, Widmar, & Swihart, ; Wróbel & Zwolak, ).…”

“…Weevil larvae (Coleoptera: Curculionidae) and moth caterpillars (Lepidoptera: Tortricidae) represent the most important groups of oak acorn predators, although weevils are responsible for the majority of seed loss (Crawley & Long 1995;Branco et al 2002;Bonal et al 2007;Espelta et al 2009). Weevil pre-dispersal predation shapes recruitment potential of trees (Crawley & Long 1995;Espelta et al 2009;Bogdziewicz et al 2017), and severely destroys crops of northern red oaks in their native range (Lombardo & McCarthy 2008;Bogdziewicz et al 2017). While less is known about moth feeding ecology, weevils are feeding specialists, with particular species best adapted to exploit particular hosts (Bonal et al 2011;Govindan et al 2012;Muñoz et al 2014;Peguero et al 2017).…”
