Using Radiation to Sterilize Insect Pests

01.12.2011
A new study published in the Journal of Economic Entomology shows that radiation can be used to effectively sterilize the light brown apple moth (LBAM), an insect pest found in Australia, New Zealand, California, Hawaii, Sweden, and the British Isles.

The light brown apple moth, Epiphyas postvittana (Walker), feeds on apples, pears, stonefruits, citrus, grapes, berries and many other plants. A native of Australia, it has been found in California since 2007.

The California Department of Food and Agriculture has spent more than $70 million in CDFA and USDA funds to eradicate the LBAM, and estimates that failure to eradicate it could cost California growers over $133 million per year.

The article, "Radiation Biology and Inherited Sterility of Light Brown Apple Moth (Lepidoptera: Tortricidae): Developing a Sterile Insect Release Program" is available now in PDF format at http://bit.ly/vuH0sT.

Using similar methodologies in two different laboratories, the authors coordinated radiation biology studies between two geographically isolated LBAM populations from Australia and New Zealand. The results showed that for both populations, an irradiation dose of 250 Gy administered to LBMA pupae induced >95% sterility in females and >90% sterility in males. These results can be used to initiate a suppression program against the LBMA where sterile males are released, mate with wild females, and no offspring are produced. If successful, this technique can largely eliminate the need for pesticides.

"These results suggest that a sterile insect technique (SIT) or F1 sterility program can be applied to control an infestation of Epiphyas postvittana, but these would still be reliant on complementary information such as physical fitness and modeling of overflooding ratios." according to the authors. "The challenge now is to identify the dose of radiation that would provide a balance between insect sterility and field competitiveness."

The Journal of Economic Entomology is published by the Entomological Society of America (http://www.entsoc.org), the largest organization in the world serving the professional and scientific needs of entomologists and people in related disciplines.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
