Summary: In this study, a highly pathogenic Aspergillus fijiensis strain, GDIZM-1, was isolated from naturally infected cadavers of the Asian citrus psyllid, Diaphorina citri. The strain was found to be non-aflatoxin B-1 producer and showed high pathogenicity against D. citri nymphs and adults under laboratory and greenhouse conditions. These findings provide a basis for the development of a new microbial pesticide against D. citri.

Summary: Flight capacity of the citrus psyllid Diaphorina citri, the main vector of Huanglongbing disease, is influenced by high temperatures and humidity levels. In high heat environments, D. citri tends to engage in shorter flights with decreased flight distance and duration. Temperature has a greater impact on flight capacity compared to humidity, with optimal temperatures for long dispersion observed at 26 degrees Celsius.

Summary: An analysis of Mexican trapping program samples led to the proposal of a sequential sampling plan for decision making in intervention against Diaphorina citri, a vector of Candidatus Liberibacter asiaticus. The study revealed that the application of these sampling plans resulted in cost savings and improved intervention accuracy by reducing the number of insect control interventions.

Summary: The aim of this study was to evaluate different protein sources as supplements to improve the growth and conidiation of Hirsutella citriformis. The results showed that wheat bran significantly promoted mycelium growth, while higher conidiation was observed on oat grains supplemented with wheat bran. The use of Hirsutella citriformis gum improved the biological control against D. citri adults.

Summary: The Asian citrus psyllid (ACP) was detected for the first time in the Republic of Benin, West Africa. DNA barcoding confirmed its identity and revealed a common origin with ACP from Nigeria. Although the ACP samples tested negative for HLB-associated bacteria, swift actions are required to prevent the establishment and spread of HLB in Benin.

Summary: The Asian citrus psyllid (ACP), a vector of Huanglongbing, can be controlled using synthetic insecticides. However, overuse of these insecticides can lead to resistance and environmental issues. Therefore, the study of naturally derived biopesticides such as sucrose fatty acid ester and 2-methoxy-4-propylphenol is important.

Summary: This study successfully targeted and silenced hexokinase gene in the Asian citrus psyllid using RNAi technology, resulting in impaired chitin synthesis, insect mortality, and abnormal phenotypes. These findings support the potential of using HK genes as a new target for citrus pest control.

Summary: The study found that cover crops in citrus groves may not be ideal refuges for Asian citrus psyllid, as the psyllids prefer feeding on xylem in citrus plants and showed little to no preference for phloem in cover crops.

Summary: The study demonstrated that entomopathogenic fungi could effectively kill the Asian citrus psyllid and may serve as a promising biocontrol candidate. Simultaneous use of these fungi with pesticides in an integrated pest management program could be a feasible approach.

Summary: The study found that gradual cold acclimation allows Asian citrus psyllid to survive brief periods below freezing, with a survival rate of 86% after 1 week of acclimation, providing a potential mechanism for the northern establishment of this citrus pest.

Summary: This study utilizes micro-computed tomography (micro-CT) to reconstruct the complete anatomy of the psyllid insect, providing detailed insights into the anatomy of the Asian citrus psyllid (ACP). It reveals previously unknown details such as sexual differences and anatomical structures like the coxal and scapus antennal glands. The rendered images and 3D model created from this study serve as a unique anatomical atlas and valuable tools for future research and educational purposes.
