New Insights into the Larvicidal Activity of Leptolegnia chapmanii Against Aedes aegypti: In Vitro and In Vivo Studies

Alaine M. L. Catão, Dulcimê Gonçalves Dorta, Walquíria Arruda, Cristian Montalva et autres

Leptolegnia chapmanii is an oomycete pathogen of mosquito larvae. We investigated whether nutritional factors promoting cyst germination in vitro are associated with early infection events and instar-specific susceptibility in Aedes aegypti. Cysts of the Brazilian isolate ARSEF 12829 germinated rapidly in soybean …

A discussion on the genus Stigmatomyces sensu lato and the description of two new species from Chile

Warre Van Caenegem, Cristian Montalva, Eladio Rojas, P.L.T. Beuk et autres

Taxonomic revisions in mycology often focus on well-studied fungal groups, yet obscure lineages such as Laboulbeniales (Pezizomycotina, Ascomycota) remain underexplored. Here, we address the taxonomy of Stigmatomyces sensu lato, a diverse genus of obligate biotrophic fungi parasitizing flies (Diptera). Previous work suggested …

Variation in Branch Volatile Organic Compounds of Healthy and Leaf-Damaged Araucaria araucana in Two Chilean National Parks

Washington Aniñir, Leonardo Bardehle, Cristian Montalva, Andrés Quiroz et autres

Araucaria araucana (Molina) K. Koch, an endemic conifer of Chile and Argentina, has been severely impacted in recent years by Araucaria Leaf Damage (ALD). Previous research has established that volatile organic compounds (VOCs) released by healthy (H) and leaf-damaged (LD) Araucaria araucana …

Effect of Volatile Organic Compounds from Branches of Healthy and Unhealthy Araucaria araucana (Molina) K. Koch Trees on Host Selection by Bark Beetle Sinophloeus porteri (Coleoptera: Curculionidae)

Washington Aniñir, Leonardo Bardehle, Cristian Montalva, Andrés Quiróz et autres

Araucaria araucana is one of the longest-living Chilean trees. Recently, Araucaria Leaf Damage disease, which causes damage to branches and crowns, was detected. Sinophloeus porteri, a bark beetle affecting A. araucana, could be associated with foliar damage. However, little is known about …
