Known for its intoxicating effects on felines, catnip oil may also have a future in termite control. Recent experiments by USDA Forest Service researcher Chris Peterson show that catnip oil repels and even kills termites in a laboratory setting.

Peterson, a researcher with the Forest Service Southern Research Station (SRS), and fellow researcher Janice Ems-Wilson, a chemist at Valencia Community College in Orlando, FL, presented the results of their research at the national meeting of the American Chemical Society held March 23 – 27 in New Orleans.
An entomologist with the SRS Wood Products Insect Research unit in Starkville, MS, Peterson has been testing essential catnip oil as a possible replacement for the more toxic pesticides presently used to control termites. Probably the most common termite control method is treating the soil next to wood structures with chemical compounds: some of the active ingredients of traditional termiticides, such as chlordane and chlorpyrifos, have lost their registrations in the U.S. due to their toxicity. New, more eco-friendly compounds are being sought to fill the void.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
