Huanglongbing (HLB) disease detection in Cuba in 2006 led to a turn in citrus management in the country, including the production of certified budwood in protected nurseries, eradication of symptomatic plants and old orchards, and chemical control of the vector Diaphorina citri. This dramatic shift in citrus farming could have affected the incidence and composition of citrus tristeza virus (CTV) populations. This work aimed to determine CTV incidence and characterize viral isolates from the main Cuban citrus-producing areas. A survey throughout the country was carried out which resulted in the collection of 27 CTV isolates. Results showed a decrease of CTV incidence in western and central areas of the country, but an increase in the East, compared to previous reports. Bioindexing showed that most of the isolates induced none or mild symptoms. Serological characterization using seven different CTV specific monoclonal antibodies (MAb) showed heterogeneity among the 27 isolates. Six out of twenty-seven were MCA13-reactive, a MAb associated to the presence of severe CTV isolates. Nevertheless, sequence comparison of the p20 , p23 and p25 genes evidenced a high nucleotide sequence identity among isolates, and according to the phylogenetic analyses, all the sequences belonged to the CTV T30 genotype. Thus, our results showed a decrease in the CTV incidence in the surveyed areas and the broad dissemination of mild CTV isolates of the T30 genotype, which could be partially explained by the shift in the management programs implemented for CTV and HLB control in Cuba. • A survey in Cuban citrus areas during 2012–2015 showed a decrease in CTV incidence. • Characterization of 27 isolates showed the predominance of mild T30-CTV isolates. • The 27 CTV isolates were highly homogeneous in their biological characteristics. • The HLB management program, in conjunction to the pre-existent CTV one, could partially explain the results.

Acerola (Malpighia emarginata DC.) is a shrub species that grows in tropical and subtropical climates; it is native to southern Mexico, Central America and northern South America. Its fruits have a high vitamin C content and are considered one of the most potent and least toxic natural antioxidants. Among the main pest species causing crop damage is the genus Anthonomus (Coleoptera: Curculionidae). In 2019, surveys were conducted in the western region of Cuba to evaluate the presence of pests in plants located in the localities of Alquizar and Ceiba del Agua, belonging to the province of Artemisa. They collected 100 flowers and 100 green fruits of different sizes that presented deformations and symptoms characteristic of damage caused by an insect. A total of 344 holes were counted, for an average of 3.4 holes per fruit; in addition, 230 larvae, 114 eggs, 65 pupae and 81 adults of a coleopteran. The objective of the work was to identify the species of the insect associated with the observed damage. The morphological characters of the collected insect allowed the identification of Anthonomus sisyphus Clark as the cause of damage to acerola fruits and constitutes the first report of this species as a pest of this fruit tree in Cuba.
