Trapping and Repellent Techniques for Huanglongbing Management in Citrus Orchards: Innovative Strategies to Combat Vector-Mediated Disease Transmission

Abstract

The global increase in human population has heightened the demand for citrus fruits and their derivatives, necessitating effective management strategies to mitigate the impact of huanglongbing (HLB) disease. Caused by gram-negative bacteria such as ‘Candidatus Liberibacter asiaticus’, ‘Candidatus Liberibacter africanus’, and ‘Candidatus Liberibacter americanus’, HLB is primarily transmitted by the insect vector Diaphorina citri. While traditional vector suppression methods using insecticides have proven ineffective, innovative approaches are required to control disease spread. This study aims to address the persistent nature of the vector and its ability to transmit HLB throughout its life cycle by emphasizing trapping and repellent techniques. By implementing early detection methods, utilizing disease-resistant citrus varieties, employing disease-free seeds, enhancing nutritional regimes, and reducing vector populations, promising results have been achieved in reducing vector populations and limiting HLB inoculum. The implications of this research underscore the importance of adopting trapping and repellent strategies, alongside the use of disease-free citrus plants, to effectively manage HLB and safeguard citrus plantations worldwide.
