Infestation of potato by the potato tuber moth (Phthorimaea operculella) varies markedly among cultivars, yet the chemical and molecular mechanisms underlying this variation remain poorly understood. Here, we combine field surveys, chemical ecology, functional genomics, and structural modeling to reveal how cultivar-specific volatile profiles shape moth oviposition behavior and pest outcomes. Field and laboratory assays identified marked differences in adult attraction, oviposition, and larval damage among potato cultivars, which correlated with distinct blends of emitted volatile organic compounds (VOCs).

Ministers from around Africa have gathered in the Islamic Republic of Mauritania’s capital to agree on ways the Food and Agriculture Organization of the United Nations (FAO) can help their countries revive progress towards reducing hunger over the next two years.This week’s 34th Session of the Regional Conference for Africa (ARC34) indicated priority regional and local themes and areas for FAO to take into account while preparing the Programme of Work and Budget for the next biennium, and aligning with FAO’s Strategic Framework, Medium-Term Plan and country programming frameworks.

Researchers from Arba-Minch University and Borena University in Ethiopia evaluated the effects of genetically modified organisms (GMOs) used as livestock feed. GM crops have been widely adopted to improve traits such as yield, nutrition, and resistance to diseases and pests. The study, published in the Journal of Veterinary Medicine and Animal Health, highlighted both the benefits and ongoing concerns associated with the use of GMOs as livestock feed.
