“…A complete generation usually requires 20 to 30 d (Capinera 2011), though this is strictly dependent on the optimum climatic conditions. In a laboratory, A. eugenii may reach 8 complete life cycles; however, 3 to 5 generations develop in most pepper weevil native areas (Wu et al 2019). Indeed, it is common to find adults in the fields from Mar until Jun in the native areas of the pepper weevil, but a certain amount of adults also can be recovered throughout the yr, except for the mo of Dec and Jan (Capinera 2011).…”

Anthonomus eugenii Cano (Coleoptera: Curculionidae) is one of the most severe pests for sweet and hot varieties of pepper (Capsicum spp.; Solanaceae). The species is distributed widely, principally in Central America, but in 2013 it was detected for the first time in the Lazio region of Italy. Modelling plays a key role in reducing chemical treatments used on Capsicum spp., but reliable predictions of pest populations require adjusted tools, as well as intense knowledge of the insect's biology and its typical environment. The main goal of this work is to describe the life cycle of A. eugenii with a physiologically based model, which links the population dynamics with the environmental parameters. More specifically, this analysis focuses on the different response of the age-structured model in relation to the development rate function in input. Two methodologies to determine the best representative development rate function suitable for simulations are proposed; the first is "a priori analysis," whereas the second is the "a posteriori analysis." Simulations were compared with semi-field data, collected in a controlled experimental greenhouse where A. eugenii developed in varying temperature conditions. Results showed that the model used is adequate to describe A. eugenii population dynamics and highlighted how the a posteriori analysis can be essential to (i) analyze the simulation outputs, and (ii) determine the best representing development rate function, if the a priori analysis does not provide this information sufficiently clearly.

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.
