Scientists from the University of Plymouth and the Institute of Evolutionary Biology in Barcelona have used cutting edge DNA technology to demonstrate that one of Europe's top freshwater predators is actually two species rather than one.
Biologists have developed a solution for controlling the invasive Asian hornet Vespa velutina based on the insect's natural chemical mating instincts. They deciphered the sex pheromone of the insect and devised a method of luring males into traps baited with synthesized versions of the pheromones. Vespa velutina has recently spread its presence with invasions in Europe and Korea, posing risks to honey bees, humans and related economics.
The Phlebotomus papatasi sandfly is responsible for spreading Leishmania throughout the tropics and subtropics. How individuals in areas endemic for Leishmania infection react to sandfly saliva depends on their long-term exposure to the flies, researchers now report PLOS Neglected Tropical Diseases TK.
Pest resistance to genetically engineered crops Bt crops is evolving faster now than before, UA researchers show in the most comprehensive study to date. But as expected from evolutionary theory, resistance can be delayed if farmers comply with recommendations to make use of abundant refuges.
Neurons that enable honeybees to sense the waggle dance -- a form of symbolic communication used by female bees to inform the hivemates about the location of a food source -- are investigated in new research published in JNeurosci.
Understanding how parasitoids and hosts interact, and how their interactions change with human influence, is critically important to understanding ecosystems. New research by an international team of researchers finds mathematical models can predict complex insect behavioural changes using a simple description of insect preferences.
Scientists have discovered how the wiring of bees' brains helps them plot the most direct route back to their hive.
Researchers use genetic sequencing of museum specimens to confirm that the Lord Howe Island stick insect, once thought to be extinct, survived by hiding out on a nearby island.
Lord Howe Island stick insects were once numerous on the tiny crescent-shaped island off the coast of Australia for which they are named. Now, researchers reporting in Current Biology on Oct. 5 who have analyzed the DNA of living and dead Lord Howe Island stick insects have some good news: those rediscovered on Ball's Pyramid, which are now being bred at the Melbourne Zoo and elsewhere, really are Lord Howe Island stick insects.
A new study in Scientific Reports suggests the Malagasy striped whirligig beetle Heterogyrus milloti boasts a genetic pedigree stretching back to the late Triassic period.
