New study may aid rearing of stink bugs for biological control

06.01.2014
Many people think of stink bugs as pests, especially as the brown marmorated stink bugs spreads throughout the U.S.

However, certain stink bugs are beneficial, such as Podisus nigrispinus (Dallas), a predatory stink bug that is considered an important biological control agent for various insect pests of cotton, soybean, tomato, corn, kale, and other crops.

Now a new study appearing in Annals of the Entomological Society of America called "Effect of Egg Rearing Temperature and Storage Time on the Biological Characteristics of the Predatory Stink Bug Podisus nigrispinus (Hemiptera: Pentatomidae)" may aid companies that rear these beneficial insects and the growers who use them in the field. This is the first study to examine the storage technique for the predator P. nigrispinus to improve its mass rearing in laboratory conditions without compromising the quality of insects produced.

"Our goal was to evaluate the effect of low temperatures on the biological characteristics of P. nigrispinus, with the aim of optimizing mass-rearing programs for this potential biological control agent," the authors wrote. "The successful storage of eggs at a low temperature is important for the use of natural enemies in pest control programs, as it allows greater flexibility in the mass-rearing process. It also increases the availability of insects for release in the field at the earliest opportunity."

The researchers found that the optimum temperature for P. nigrispinus eggs to be stored is 15 degrees celsius, and that the eggs could be stored for up to 17 days without significantly affecting most of the biological characteristics analyzed in the study.

"Our results suggest that low temperatures can be used to store eggs for mass rearing of this potential biological control agent," the authors write. "This would allow P. nigrispinus to be used in augmentative releases that could be coordinated with pest outbreaks in the field."

The full study (DOI: http://dx.doi.org/10.1603/AN13027) is published in the January 2014 edition of Annals of the Entomological Society of America.

Annals of the Entomological Society of America is published by the Entomological Society of America, the largest organization in the world serving the professional and scientific needs of entomologists and people in related disciplines. Founded in 1889, ESA today has more than 6,500 members affiliated with educational institutions, health agencies, private industry, and government. Members are researchers, teachers, extension service personnel, administrators, marketing representatives, research technicians, consultants, students, and hobbyists.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
