University of Washington researchers have created a sensor system that can ride aboard a small drone or an insect, such as a moth, until it gets to its destination.
Millions of people plant pollinator gardens in an effort to provide monarch butterflies with food along their annual migration route from overwintering sites in the highland forests of central Mexico to summer breeding grounds in the United States and southern Canada. For the first time, entomologists studied how effective native milkweed cultivars in small gardens are at attracting and supporting monarchs - their results suggest that this can be a valuable additional food source.
Climate change is affecting the spread and severity of infectious diseases around the world -- and infectious diseases may in turn be contributing to climate change, according to a new paper in Trends in Ecology & Evolution. The research, led by Vanessa Ezenwa, a professor of ecology at the University of Georgia, and funded by the Living Earth Collaborative at Washington University in St. Louis, describes how parasites can cause animals to produce more methane, a powerful greenhouse gas.
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers at the University of California, Davis, found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring.
he songs that crickets and katydids sing at night to attract mates can help in monitoring and mapping their populations, according to Penn State researchers, whose study of Orthoptera species in central Pennsylvania also shed light on these insects' habitat preferences.
An international team of scientists established that biological invasions will increase by 36 percent between 2005 and 2050. Modeling suggests that Europe is likely to experience the strongest biological invasions, followed by Asia, North America and South America.
The number of alien (non-native) species is expected to increase globally by 36% by the middle of this century, compared to 2005, finds new research by an international team involving UCL and the Senckenberg Biodiversity and Climate Research Centre.
University of Maryland scientists discovered mosquitos are missing a gene that's critical for survival in other insects. Alys Jarvela noticed the missing gene and went on the hunt to find out how mosquitos survive without it. She identified the first example of nature swapping out closely related genes, a phenomenon that poses caveats for studies using model organisms as proxies for other species. The research was published September 30, 2020, in Communications Biology.
A new surgery tool based on the egg-laying organ of parasitic wasps could advance minimally invasive surgery by enabling tissue removal in deeper areas of the body while further minimising trauma and patient recovery time. Researchers at Delft University of Technology in the Netherlands based their prototype on the ovipositor of wasps, an ultra-thin flexible organ, which uses friction forces generated by sliding internal blades to achieve efficient transport on a small scale.
Small watery droplets on the edges of blueberry bush leaves are loaded with nutrients for many insects, including bees, wasps and flies, according to a Rutgers-led study, the first of its kind. The study, published in the journal Proceedings of the Royal Society B: Biological Sciences, suggests that these droplets are an important but underexplored feature in plants, with profound implications for insects in agricultural and natural ecosystems.
