Adult weevils were sampled weekly in untreated and insecticide-treated plots using a sweep net. Sweep net catches showed that the abundance of A. rubi adults had two peaks; the first between late-April and early-May, and the second between late-June and mid-July. Linear regression revealed a strong relationship between overwintered and new-generation adult densities. The overwintered-generation adults had generally higher mean population densities than the new-generation. A significant linear decrease was observed in strawberry yields as densities of overwintered-generation adults increased. Percentage yield losses varied between 1.64% and 13.42% among sites. Estimated economic injury levels ranged from 1.00 to 4.00 adults per sweep depending on the management scenario, control cost, control efficacy, and crop value.eninfo:eu-repo/semantics/closedAccessSstrawberry blossom weevilCurculionidaeRelative samplingEconomic thresholdIntegrated pest managementBud weevil coleopteraStrawberry blossom weevilDamagePatternsRemovalYieldAgricultureEastern hemisphereFragaria x ananassaAgricultural economicsCost-benefit analysisCrop damagePopulation dynamicsArticle0002333320000022-s2.0-27144449955103510412412AgronomyAnthonomus Signatus; Fragaria; Direct Marketing
