Anatomical study of the red flour beetle using synchrotron radiation X-ray phase-contrast micro-tomography
In this study, we described in situ the internal organs of the red flour beetle Tribolium castaneum Herbst 1797, a widespread pest of cereals and stored food causing serious damage to the human economy. Two-dimensional virtual sections and volumetric reconstructions of the nervous, alimentary and reproductive systems were carried out in both sexes. The results provided a comprehensive overview of the morphological characteristics of this species, such as the different maturation stages of ovarioles and the realistic location, size and shape of internal organs. Given the great interest in this model species in experimental ...

Trump's Hiring Freeze Could Imperil Breakthrough Discovery On Bees
Julia Fine was all set for the next chapter. She’d packed her bags and moved out of her apartment, and was days away from making the drive from Pennsylvania to Utah, where she planned to start work as a postdoctoral scholar with the Agricultural Research Service, the U.S. Department of Agriculture’s research agency. “I had made all the plans,” said Fine, a bee researcher who recently completed her doctorate in entomology at Pennsylvania State University. “I was supposed to start as soon as possible.” But on Jan. 23, just three days after President Donald Trump’s inauguration,...

Rift Valley fever virus and European mosquitoes: vector competence of Culex pipiens and Stegomyia albopicta (=  Aedes albopictus)
Abstract Rift Valley fever (RVF) is a mosquito‐borne disease caused by the Rift Valley fever virus (RVFV). Rift Valley fever affects a large number of species, including human, and has severe impact on public health and the economy, especially in African countries. The present study examined the vector competence of three different European mosquito species, Culex pipiens (Linnaeus, 1758) form molestus (Diptera: Culicidae), Culex pipiens hybrid form and Stegomyia albopicta (= Aedes albopictus) (Skuse, 1894) (Diptera: Culicidae). Mosquitoes were artificially fed with blood containing RVFV. Infection, disseminated infect...

Integrated vector control of Chagas disease in Guatemala: a case of social innovation in health
ConclusionsWhen social innovation criteria are included in a health control initiative, the community-based research and the interdisciplinary and intersectoral participation facilitate the implementation of the control strategy, the perceived benefits by the community and its empowerment to sustain and share the strategy. The case study provided understanding of the intersectoral and interdisciplinary dynamics in particular contexts, and documented the relevance of innovation criteria in health processes.

Fruit Flies Are Spreading Across U.S. Crops. The Government ’s Outdated Approach Isn’t Helping
For two weeks in August, a crew of workers systematically confiscated every orange in Vince Bernard’s groves in Valley Center, Calif. They buried the oranges—at least $500,000 worth of fruit, Bernard says—in ditches on his neighbor’s property. They did so by order of the U.S. government, which came accompanied by armed California Highway Patrol officers and which did not pay Bernard a penny for the crops. Bernard’s oranges were destroyed because the California Department of Food and Agriculture (CDFA) found five Mexican fruit flies on a neighbor’s property, which it considers “an i...
