Migratory moths profit from their journey

13.09.2012
It isn’t only birds that move south as autumn approaches. Some insects also live their lives on the same principle.
A new study of migratory insects has just been published that shows that a considerably higher number of insects survive and migrate back south in the autumn than was previously believed.

“These results are really exciting, because we have managed to show that it really is profitable for insects to migrate north at the start of the summer”, says Lars Pettersson, a Reader at the Department of Biology, Lund University, Sweden.

The findings help to fundamentally alter our understanding of insect migration and could also have an impact on how the spread of pests and disease-carrying insects is dealt with. Behind the study is an international group of researchers, including Dr Pettersson from Lund University.

The researchers have used various methods and results from both Britain and Sweden to see that almost six times as many Silver Y moths travel south after the summer as travel north in May to June.

“The spring generation migrates to Northern Europe and their offspring migrate south again”, says Lars Pettersson.

For the Silver Y and other migratory moth and butterfly species, this means that they, just like migratory birds, can make use of the long summer days and the abundant supplies of food in the north.

According to Lars Pettersson, it is important to be able to monitor migratory insects, not only to monitor pests, but also because they are an important source of food for many birds and small mammals. In addition, it has just been shown that moths in the Noctuidae family, such as the Silver Y, could play an important role as pollinators, observes Lars Pettersson.

The present study has been published in the scientific journal PNAS.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
