Abstract: The vinegar fly (Drosophila melanogaster), long recognized as a model organism in genetics and developmental biology, has in recent years also emerged as a problematic pest in agricultural and food-related environments. Its capacity to infest fruit, disrupt storage systems, and adapt rapidly to chemical treatments underscores the pressing need for innovative and selective pest management strategies. Traditional insecticides often lack specificity, leading to ecological concerns such as resistance development, collateral damage to beneficial insects, and broader environmental risks. Against this backdrop, molecular approaches targeting essential proteins of D. melanogaster offer promising alternatives for precision control. Recent research has identified three candidate proteins encoded by the genes CG44425, CG5151, and CG6606. Preliminary in vitro assays demonstrate that these proteins undergo rapid degradation in the presence of certain inhibitors, suggesting their potential as molecular Achilles' heels. However, the translation of this vulnerability into effective in vivo lethality, as well as the potential off-target impacts on non-pest organisms, remain largely uncharacterized. These uncertainties highlight the need for systematic evaluation before any practical application can be realized. This study is designed to fill these critical gaps by assessing the specificity, functional indispensability, and molecular accessibility of the three candidate genes. We employ a combination of biochemical inhibition assays, genetic knockdown and knockout approaches, and phenotypic survival analyses to establish the causal links between protein disruption and organismal mortality. Additionally, comparative sequence and structural analyses will be conducted to predict the likelihood of cross-reactivity in non-target species, thereby addressing potential ecological safety concerns. By integrating molecular, ecological, and applied perspectives, this work aims to identify the most promising target protein for selective vinegar fly control. The findings will not only advance our understanding of gene-function relationships in Drosophila but also lay the groundwork for next-generation insecticide design that balances efficacy with environmental responsibility. Ultimately, the study contributes to the broader goal of developing sustainable pest management strategies that align with modern agricultural and ecological priorities.
