Plant essential oils have been suggested as a promising alternative to the established mosquito repellent DEET (N,N-diethyl-meta-toluamide). Searching for an assay with generally available equipment, we designed a new audiovisual assay of repellent activity against mosquitoes “Singing in the Tube,” testing single mosquitoes in Drosophila cultivation tubes.(More)
Arthropod–plant interactions are vital in agriculture and pharmacology. However, enhancement and quantification of plant cell behavioural activity is still a challenge. Therefore, the finding of chitosan-induced anti-fungal activity in plants suggested a promising potential. Consequently, we treated autotroph and heterotroph Chenopodium rubrum L. cell(More)
Biofortification for pro-vitamin A content (pVAC) of modern maize inbreds and hybrids is a feasible way to deal with vitamin A deficiency in rural areas in developing countries. The objective of this study was to evaluate the probability of success of breeding strategies when transferring the high pVAC present in donors to elite modern-adapted lines. For(More)
leads a global effort to breed and disseminate micronutrient-rich staple food crops to reduce hidden hunger among malnourished populations. It is an interdisciplinary program that works with academic and research institutions, civil society organizations, governments, and the private sector in more than 40 countries. 11 HarvestPlus Working Papers contain(More)
