“…Other compounds such as (E)-β-caryophyllene, (E)-4,8-dimethyl-1,3,7-nonatriene, 4,4,5,7,8-pentamethyl dihydrocoumarin, and γ-elemene were found to be correlated with both fruit maturation and the preference of weevils for mature fruits (Figure S6A-C). In this regard, volatiles, such as (E)-4,8-dimethyl-1,3,7nonatriene and an elemene isomer, have been reported as important volatiles used by pepper weevils (Anthonomus eugenii Cano, Coleoptera: Curculionidae) to locate their host plants [40,41]. Furthermore, (E)-β-caryophyllene has been reported as a volatile for host plant location used by boll weevils (Anthonomus grandis Boheman, Coleoptera: Curculionidae) [42].…”

Soursop possesses the largest fruit size of the Annona genus. However, this species is threatened by the Annonaceae fruit weevil (Optatus palmaris), which can cause the destruction of whole soursop fruits. Recently, the potential of semiochemicals for the management of this insect is highlighted, and its aggregation pheromone has been elucidated. This pheromone works well only when mixed with soursop volatiles. Thus, the aim of this research was to determine specific kairomone components to potentiate the aggregation pheromone of this Annonaceae fruit weevil. This task was carried out via volatilome analysis of soursop fruits, which was correlated with the biological activity of the identified volatiles. The GC–MS analysis of aroma collections of mature soursop fruits and flowers, determined using multivariate data analysis, confirmed a volatile differentiation between these organs. The volatile variation between fruits and flowers was reflected in weevils’ preference for mature fruits instead of flowers. Moreover, weevils’ response to soursop fruits increased with more mature fruits. This was correlated with volatile changes throughout the phenological stages of soursop fruits. The two volatiles most correlated with weevils’ attraction were benzothiazole and (E)-β-caryophyllene. These volatiles only evoked a response when mixed and potentiated the attraction of the aggregation pheromone. Thus, these two volatiles are active kairomone components with the potential for being used in combination with the aggregation pheromone of Annonaceae fruit weevils in field trials.

The pepper weevil (Anthonomus eugenii Cano) is a destructive insect pest of field and greenhouse pepper crops across North America. Its management remains challenging with significant implications for pepper production, despite a documented presence in Central America, Mexico, the United States, and the Caribbean for approximately a century, and recently in Canada. Currently, the main tools and methods applied to manage pepper weevil populations in greenhouse peppers are the implementation of strict biosecurity protocols, diligent monitoring, physical and cultural management techniques, and chemical insecticides when necessary. However, these tools can be costly, labor-intensive, and insufficient, particularly when new outbreaks go undetected for prolonged periods. Additionally, the use of available insecticides is limited due to significant nontarget effects these have on biological control agents used to manage other important greenhouse pepper pests. Recently, research efforts have focused on developing better tools for pepper weevil management to mitigate a rising incidence of insecticide resistance and the spread of weevils into temperate regions, however, multiple constraints remain. Here, we review the current state of knowledge of the pepper weevil and identify information gaps, which future research should address to improve the targeted management of this pest in greenhouse pepper production systems.
