The e-ROSA project seeks to build a shared vision of a future sustainable e-infrastructure for research and education in agriculture in order to promote Open Science in this field and as such contribute to addressing related societal challenges. In order to achieve this goal, e-ROSA’s first objective is to bring together the relevant scientific communities and stakeholders and engage them in the process of coelaboration of an ambitious, practical roadmap that provides the basis for the design and implementation of such an e-infrastructure in the years to come.
This website highlights the results of a bibliometric analysis conducted at a global scale in order to identify key scientists and associated research performing organisations (e.g. public research institutes, universities, Research & Development departments of private companies) that work in the field of agricultural data sources and services.

Laboratory and field studies on the effect of natural control measures against insect pests in stored maize in Ethiopia
Laboratory and field studies were conducted with stored maize in western Ethiopia, against storage pests using the diatomaceous earth SilicoSec (R) (SS), pirimiphos-methyl (PMM) and a range of plant powders, oils, wood ash and other inert materials. In the laboratory, the effects of the substances were tested on Sitophilus zeamais. Fresh powder of Chenopodium ambrosioides (MTP) at 20 % w/w killed 100 % of maize weevils within 6 days, at 2.5 % within 8 days. Powders of leaves (NLP) (20 % w/w) and kernels (NSP) (3 % w/w) of Azadirachta indica (neem) exerted a weevil mortality of about 90 % after 12 days. Progeny emergence was delayed in NLP, and suppressed by NSP. Wood ash at 5 and 10 % w/w induced 100 % mortality of weevils within 15 days in the laboratory, and there was no progeny. These effects lasted for > 300 days, in the laboratory. Admixing sand at 50 % and tef at 70 % w/w induced weevil mortalities of about 90 % after 4 weeks, with a lowered progeny production. Treatments of maize with oils of neem, sunflower, maize, sesame and of Guizotia abbyssinica at 10 ml kg(-1) exerted a mortality and reduction of progeny of 100 %, for 318 days. But the germination of maize seeds was reduced. In traditional field stores, four substances were tested. Wood ash (at 5 % w/w) and tef (at 33 % w/w) performed worse than in the laboratory, effects lasting for 14 weeks, only, in contrast to SS and PMM. The mechanisms and prospects of the observed effects are discussed.
