Characterizing herbivore resistance mechanisms: spittlebugs on brachiaria spp. as an example by Parsa, S, Sotelo, G., Cardona, C.

“…Several species of African grasses of the genus Brachiaria are valuable forage and pasture plants in the Neotropics, but they can be severely challenged by several native species of spittlebugs (Hemiptera: Cercopidae).To assess their resistance to spittlebugs, plants are vegetatively-propagated by stem cuttings and allowed to grow for approximately one month, allowing the growth of superficial roots on which spittlebugs can feed. …”

Tasa intrínseca de crecimiento de Aleurotrachelus socialis (Hemiptera: Aleyrodidae) en yuca Manihot esculenta by Holguin, CM, Carabalí Muñoz, A., Bellotti, Anthony C.

“…The whitefly Aleurotrachelus socialis Bondar (Hemiptera: Aleyrodidae) is one of the most important pests in cassava (Manihot esculenta Crantz) crops in the Neotropics. In Colombia, this is the major pest to the crop in the departments of Cauca, Valle del Cauca and Tolima, causing yield losses in experimental fields of up to 79%. …”

The Passion Fruit Genome by Carneiro Vieira, Maria Lucia, Portugal Costa, Zirlane, Mello Varani, Alessandro, Sader, Mariela Analia, Cauz Santos, Luiz Augusto, Augusto Giopatto, Helena, Egoávil del Reátegui, Alina Carmen, Bergès, Hélène, Barros Monteiro Vitorello, Claudia, Carnier Dornelas, Marcelo, Pedrosa-Harand, Andrea

“…The genus has long attracted considerable attention due to its economic value, broad geographic distribution and remarkable species diversity, which are found in tropical and subtropical regions of the Neotropics. Despite their biological attributes and economic importance, the species are largely neglected when it comes to conducting genomic studies. …”

Do additional sugar sources affect the degree of attendance of Dysmicoccus brevipes by the fire ant Solenopsis geminata? by Carabalí-Banguero, D.J., Wyckhuys, Kris A.G., Montoya Lerma, J., Kondo, T, Lundgren, Jonathan G.

“…Mutualistic interactions between ants and Hemiptera are mediated to a large extent by the amount and quality of sugar‐rich honeydew produced. Throughout the neotropics, the predaceous fire ant Solenopsis geminata (Fabricius) (Hymenoptera: Formicidae) is found in association with colonies of the pineapple mealybug, Dysmicoccus brevipes (Cockerell) (Hemiptera: Pseudococcidae), which they actively tend and protect from attack by natural enemies. …”

Structure, diversity and the conservation value of tropical dry forests in highly fragmented landscapes by Lanuza Lanuza, Oscar R, Espelta, Josep Maria, Peñuelas, Josep, Peguero, Guille, y otros dos autores más

“…Although tropical dry forests are among the most degraded and fragmented biomes in the world, we still have a poor understanding of their basic ecological features and conservation status, particularly in the Neotropics. Here, we assess the diversity, composition, structure and conservation value of tropical dry forests in a highly fragmented landscape in Nicaragua. …”
