“…The same climatic conditions are present in Central Chile, where the C. bacillisporus isolate was recovered, suggesting that VGIII is spreading outside the endemic areas and is potentially able to colonize a wide area in Chile covering about 150,000 km 2 . The same pattern of colonization has been present in other organisms that colonized central Chile, reinforcing the results presented here ( Carvajal et al, 2019 ). This area corresponds to the most populated area of the country, including the capital city of Santiago.…”

Expansion of the Emerging Fungal Pathogen Cryptococcus bacillisporus Into America: Linking Phylogenetic Origin, Geographical Spread and Population Under Exposure Risk

In 2018 the fungal pathogen Cryptococcus bacillisporus (AFLP5/VGIII) was isolated for the first time in Chile, representing the only report in a temperate region in South America. We reconstructed the colonization process of C. bacillisporus in Chile, estimating the phylogenetic origin, the potential spread zone, and the population at risk. We performed a phylogenetic analysis of the strain and modeled the environmental niche of the pathogen projecting its potential spread zone into the new colonized region. Finally, we generated risk maps and quantified the people under potential risk. Phylogenetic analysis showed high similarity between the Chilean isolate and two clonal clusters from California, United States and Colombia in South America. The pathogen can expand into all the temperate Mediterranean zone in central Chile and western Argentina, exposing more than 12 million people to this pathogen in Chile. This study has epidemiological and public health implications for the response to a potential C. bacillisporus outbreak, optimizing budgets, routing for screening diagnosis, and treatment implementation.

“…The losses in California during 2013 were estimated at $679 million USD (Palumbo 2016). Even though quarantine measures have been taken for this pest, its distribution appears to have reached important commercial crop regions in the Americas and it threatens to spread to more ecosystems with potential economic impact in cruciferous and other crops (Carvajal et al 2018).…”

Field studies and molecular forensics identify a new association: Idris elba Talamas, sp. nov. parasitizes the eggs of Bagrada hilaris (Burmeister)

A species of Idris Förster (Hymenoptera: Scelionidae) is found to parasitize the eggs of Bagrada hilaris (Hemiptera: Pentatomidae) and is described as new: Idris elba Talamas, sp. nov. This is the first association of an Idris species with a non-spider host, and the association is confirmed with molecular diagnostic tools that enable identification of parasitoid and host from the remains of parasitized eggs.

“…Species distribution modelling (SDM) is a useful approach to distinguish potentially suitable areas for the establishment of IAS populations across uncolonized and colonized zones, and forms the basis of pest control and management . SDM provides an opportunity to estimate potential ecological interactions between species under a spatially explicit framework, such as vector‐borne infectious disease dynamics, pollination or interspecific competition .…”

BACKGROUND: Solanum sisymbriifolium is a native plant of South America introduced into Africa, which has detrimental effects on crop yields, and on the environment due to weed control treatment by burning. In South America, S. sisymbriifolium is naturally controlled by the beetle Gratiana spadicea, making this a potential option for its control in Africa. Here, we aim to generate current and future scenarios for the introduction of G. spadicea as a biocontrol agent in Africa, analysing: (i) current and future effective biocontrol areas; (ii) potentially avoided economic losses (AEL), and chemical control costs and savings; and (iii) avoided carbon emissions (ACE) associated with the non-burning of crop fields. We combine species distribution models (SDM) with land cover maps to estimate current and future effective biocontrol considering Representative Concentration Pathways (RCP) 4.5 and 8.5 climate change scenarios. We then estimate AEL and ACE using biocontrol, and chemical control costs and savings. RESULTS: The effective biocontrol area reached 392 405 km 2 in 18 countries, representing 40% of potentially affected croplands. Climate change induced a decrease in affected croplands and effective biocontrol. The estimated AEL reached US $45 447.2 ± 5617.3 billion distributed across 16 countries, while the estimated chemical control costs and savings reached US$1988.5 billion and 1411.8 billion, respectively. Potential ACE reached 36.3 ± 5.4 Tg.CONCLUSIONS: Our study provides evidence for the potential benefits of biological controllers on economic losses and carbon emissions, which can be incorporated into sustainable development in low-income countries.
