Evaluating the link between chemicals and declining insect populations

Using a library of 1,000+ agrochemicals, scientists saw significant changes in behaviour and long-term survival of different insect populations

29-Oct-2024 - Few people are fans of stink bugs, mosquitoes, or boll weevils, but insects play a key role in the circle of life that makes up the planet’s environment. In fact, world-renowned biologist E. O. Wilson famously declared that if insects vanished, our environment would collapse. Scientists have ...

Bee-friendly protection for plants

New types of sensors could help to develop plant protection products that are safe for bees

17-Oct-2024 - The increasing global demand for plant-based foods makes the use of pesticides necessary in order to protect crops from pests and ensure crop yields. However, there is one major disadvantage: among others, the widespread use of pesticides has led to a considerable reduction in insect populations ...

Automated analysis of German insect diversity

DNA provides almost 32,000 species

14-Oct-2024 - Insect decline is not just an ecological problem, but also an economic one. But are entire species disappearing completely? Or are there fewer animals of each species? The automated laboratory workflow developed by UDE biologists provides answers. How do you protect what you don't know? Global ...

Faster neuroborreliosis diagnosis using biomarkers

Clear threshold value of the cellular messenger substance CXCL13 allows diagnosis of neuroborreliosis to be improved

11-Jul-2024 - A newly defined threshold for the concentration of the cytokine CXCL13 may improve the diagnosis of neuroborreliosis. The clinical diagnosis of this disease, which is caused by infections from tick bites, is still difficult and often occurs long after infection. CXCL13 now makes it possible to ...

Identify, engage, assassinate: How seahorse-like toxins kill insects

Researchers reveal the first-ever detailed structure of the bacterial toxin Mcf1: Useful for engineering novel biopesticides

02-Feb-2024 - Insect-killing bacteria typically release toxins to slay their hosts. The bacterium Photorhabdus luminescens, for example, pumps insect larvae full of the lethal ‘Makes caterpillars floppy 1’ (Mcf1) toxin, leading them to first become droopy and then dead. However, it has so far been a mystery ...

X-ray laser uncovers the structure of a natural anti-mosquito insecticide

Bacterial protein found to work against more species of mosquito as previously thought

01-Dec-2023 - An international research team has analysed a naturally produced toxin against insects with atomic precision using the most powerful X-ray laser in the world. The data taken at the European XFEL help with figuring out the mode of action of the insecticide, which is produced by a bacterium. This ...

Nanoplastics can move up the food chain from plants to insects and from insects to fish

Novel, metallic fingerprint-based technique to detect and measure nanoplastics in organisms

14-Sep-2022 - A new study from the University of Eastern Finland shows that lettuce can take up nanoplastics from the soil and transfer them into the food chain. The concern about plastic pollution has become widespread after it was realised that mismanaged plastics in the environment break down into smaller ...

Scientists create a DNA test that identifies Lyme disease in horses

A test under development by a Rutgers professor could have applications for humans and dogs, too

18-Aug-2022 - A Rutgers scientist aiming to help heal a sick horse created an ultra-sensitive DNA test that could have applications for difficult-to-detect illnesses in humans such as Lyme disease. As described in a study published in the Journal of Veterinary Diagnostic Investigation, a special DNA test ...

Genomic studies open up a wealth of bioactive small molecules in insect-killing bacteria

27-Apr-2022 - Interactions between microbes and other organisms are mediated by a plethora of small molecules, also called natural products. A research team led by Dr. Yi-Ming Shi and Prof. Helge Bode from the Max Planck Institute for Terrestrial Microbiology has now performed a systematic analysis of ...
