Airborne Sound Detection in Manduca sexta Caterpillars

We investigated the hearing mechanism of Manduca sexta caterpillars to determine whether their behavioural responses to acoustic stimulation are caused by sound-induced substrate vibration or by direct detection of airborne sound. Behavioural response thresholds to direct substrate vibration and airborne sound were measured using pure-tone stimuli at 150 Hz and 2000 Hz. A frequency of 150 Hz was…

Delaying cherry blossom to reduce frost damage

Climate change is causing many fruit trees to flower earlier, increasing their exposure to damaging late spring frosts. A study led by the University of Göttingen shows that the plant growth regulator ethephon can delay flowering in Kordia, a sweet cherry variety, potentially protecting blossoms and developing fruitlets from frost.
