Mapping pests the old fashioned way
The collaborative project “Predicting climate change-induced vulnerability of African agricultural systems to major insect pests through advanced insect phenology modeling and decision aid development for adaptation planning” was led by CIP and implemented in collaboration with the International Centre of Insect Physiology and Ecology (icipe) and the International Institute for Tropical Agriculture (IITA). In the project, pest risk assessments under potential future climates were conducted for a number of important insect pests of agricultural and horticultural crops in Africa (i.e., potato, sweetpotato, vegetables, maize, cassava, and fruit). Results of these assessments are presented in the Pest Distribution and Risk Atlas for Africa (Pest Risk Atlas for Africa, for short).
And here it is, covering 3 potato pests, 5 for sweetpotato, 4 for vegetables and 5 for maize. For each pest, there’s a lot of information on detection and identification, biology, impact, and control, as well as a detailed geographic analysis of distribution and severity, now and in the future, at various scales.
Check out, for example, what’s going to happen to sweetpotato whitefly (Bemisia tabaci) in Africa (there are also global and country maps, in this case).
This shows the absolute change in potential population growth between 2000 and 2050. Note the bad news for Central Kenya, which will be interest the mother-in-law, who rents out some bottomland for sweetpotato. And she’ll have plenty of Chinese company, by the looks of the global maps.
At least, I guess so. It’s difficult to be sure when all you have are maps in the form of images. I do hope they’ll be available on Google Earth in due course, for researchers (and indeed farmers) who want to drill down a bit.
Brainfood: Cotton domestication, Niche modelling, Finger millet double, Bird flu, Lake Chad millet, USDA Ethiopian sorghum, Phast phenotyping, Corchorus genomes
- Genome-wide divergence, haplotype distribution and population demographic histories for Gossypium hirsutum and Gossypium barbadense as revealed by genome-anchored SNPs. Parallel domestication.
- Integrating species distribution modelling into decision-making to inform conservation actions. You need really nice maps.
- Establishing a core collection of finger millet (Eleusine coracana [L.] Gaertn.) ex situ holdings of the Ethiopian genebank. Particularly interesting for the discussion of what to do with the core, now that it exists.
- Characterization of Some Ex Situ Conserved Finger Millet (Eleusine coracana (L.)) Germplasm Accessions in Sri Lanka. Unlike this one.
- Global mapping of highly pathogenic avian influenza H5N1 and H5Nx clade 2.3.4.4 viruses with spatial cross-validation. It’s the intensively raised chickens.
- Unexpected pattern of pearl millet genetic diversity among ethno-linguistic groups in the Lake Chad Basin. Different linguistic groups have genetically distinct pearl millet, but only on the western side of the lake.
- Genomic characterization of a core set of the USDA-NPGS Ethiopian sorghum germplasm collection: implications for germplasm conservation, evaluation, and utilization in crop improvement. 7,217 accessions from Ethiopia, 374 in the core subset, representing 11 highly admixed and very diverse populations.
- High-throughput phenotyping and QTL mapping reveals the genetic architecture of maize plant growth. Brave new world.
- Comparative genomics of two jute species and insight into fibre biogenesis. There are a few but interesting genetic differences between the 2 species of Corchorus cultivated for fibre. No word on the differences between fibre and vegetable varieties, if any.

- Strategies for exchange of coconut germplasm in Brazil. Zygotic embryos in Petri dish containing Y3 culture medium without sucrose can last a couple of days without bacterial infection.
- Phylogenetic relationships within Lactuca L. (Asteraceae), including African species, based on chloroplast DNA sequence comparisons. The African species are probably not Lactuca at all.
- The Pacific yam (Dioscorea nummularia Lam.), an under-exploited tuber crop from Melanesia. It can be improved through crossing with itself, or with other species.
- Eco-geographical assessment of Avena L. wild species at the VIR herbarium and genebank collection. Some more collecting to be done.
- The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project. Including 15,000 plants. No word on whether any of them Avena.

- Toward a taxonomic definition of perennial wheat: a new species ×Tritipyrum aaseae described. Not entirely clear why naming it as a new species is necessary, but it’s still pretty cool.
- Dynamics of variety change on wheat farms in Pakistan: A duration analysis. For marginal farmers, it’s about yield, for others, quality. No word on how perennial wheat might do.

- Genomic characterisation of Arachis porphyrocalyx (Valls & C.E. Simpson, 2005) (Leguminosae): multiple origin of Arachis species with x=9. At least two distinct origins for the x=9 species.

- Genotyping-by-sequencing of a melon (Cucumis melo L.) germplasm collection from a secondary center of diversity highlights patterns of genetic variation and genomic features of different gene pools. Three subgroups, and that’s just in Puglia, the heel bit of Italy.
- Quantifying biodiversity losses due to human consumption: a global-scale footprint analysis. Food consumption is the single greatest driver of biodiversity loss, somewhere else.
- Old vegetable varieties: attitude, consumption behaviour and knowledge of German consumers. There’s a consumer segment in Germany that could be labelled “fanciers of old vegetable varieties,” apparently.
- Emerging oomycete threats to plants and animals. Be afraid.
