How do mosquitoes land and take off without our noticing? Using high-speed video cameras, a team from UC Berkeley and Wageningen University have found part of the answer: mosquitoes' long legs allow them to slowly and gently push off, but their wings provide the majority of the lift, even when fully laden with a blood meal. For comparison, mosquitoes push off with forces much less than those of an escaping fruit fly.
Well fed mosquitoes need to make a stealthy get away to avoid attracting the attention of the victim upon which they have just gorged, and now an international team of scientists have shown that mosquitoes take advantage of their long legs and a wing assisted launch to evade detection.
After mating for the first time, most females of an Australian jumping spider are unreceptive to courtship by other males, and this sexual inhibition is immediate and often lasts for the rest of their lives, according to a study published Oct. 18, 2017, in the open-access journal PLOS ONE by Vivian Mendez from Macquarie University, Australia, and colleagues.
The total flying insect biomass decreased by more than 75 percent over 27 years in protected areas, according to a study published Oct. 18, 2017, in the open-access journal PLOS ONE by Caspar Hallmann from Radboud University, The Netherlands, and colleagues.
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.
