Investigating HLB control strategies using Genetic Algorithms: A two-orchard model approach with ACP Dispersal [PDF]
arXiv, 2023 This study focuses on the use of genetic algorithms to optimize control parameters in two potential strategies called mechanical and chemical control, for mitigating the spread of Huanglongbing (HLB) in citrus orchards. By developing a two-orchard model that incorporates the dispersal of the Asian Citrus Psyllid (ACP), the cost functions and objective ...

CitDet: A Benchmark Dataset for Citrus Fruit Detection [PDF]
arXiv, 2023 In this letter, we present a new dataset to advance the state of the art in detecting citrus fruit and accurately estimate yield on trees affected by the Huanglongbing (HLB) disease in orchard environments via imaging. Despite the fact that significant progress has been made in solving the fruit detection problem, the lack of publicly available ...

Effector CLas0185 targets methionine sulphoxide reductase B1 of Citrus sinensis to promote multiplication of 'Candidatus Liberibacter asiaticus' via enhancing enzymatic activity of ascorbate peroxidase 1. [PDF]
Mol Plant PatholTargeted by effector CLas0185, CsMsrB1 enhances enzymatic activity of CsAPX1 during ‘Candidatus Liberibacter asiaticus’ infection, which subtracts reactive oxygen species accumulation and compromises plant resistance. Abstract Citrus huanglongbing (HLB) has been causing enormous damage to the global citrus industry.

Molecular evidence for the presence of huanglongbing in Pakistan [PDF]
Australasian Plant Disease Notes, 2007 The presence of Candidatus Liberibacter asiaticus in citrus orchards in the North-West Frontier Province of Pakistan has been confirmed. Samples of DNA extracted from leaves of putatively infected citrus plants and from the vector of the disease, Diaphorina citri, were subjected to analysis using PCR and produced DNA amplicons characteristic of this ...

Biotechnology & Biotechnological Equipment, 2020 The Asian citrus psyllid, Diaphorina citri Kuwayama, is one of the most destructive pests of citrus and the primary vector of Candidatus Liberibacter spp., which cause citrus Huanglongbing (HLB). Microbial insecticides based on entomopathogenic fungi are
