Research progress on the mahogany shoot borer, Hypsipyla grandella (Lepidoptera: Pyralidae): new perspectives for its management
摘要
The mahogany shoot borer, Hypsipyla grandella, is one of the most serious pests affecting Spanish cedar and mahogany crops. This pest species has halted the massive commercial propagation of these crops in Latin America. The lack of effective control measures, combined with the limited application of cutting-edge techniques to investigate the insect’s biology and ecology, has hindered the development of data-based control strategies. In this review, we performed a systematic survey of the available scientific literature on H. grandella using selected academic databases. We categorized the retrieved studies according to their main research focus, allowing us to identify research trends and knowledge gaps in the current state of research on this pest species. Our analysis indicates that most studies have focused on descriptive aspects of the insect’s biology and life cycle, whereas host–insect interactions and the chemical ecology conducted by this insect remain poorly explored. Additionally, we provide a summary and discussion of the principal management strategies evaluated to date, encompassing both conventional silvicultural practices and alternative or integrated approaches. Finally, we suggest innovative research directions to address the methodological gaps, which we believe are necessary for the development of new management strategies.
