Effects of temperature and humidity on the presence and prevalence of a common fungal parasite on an invasive ladybird

open access: yesEcological Entomology, EarlyView.
We investigated how temperature and relative humidity influence the parasitic fungus Hesperomyces harmoniae on the invasive ladybird Harmonia axyridis under controlled laboratory conditions. Abiotic factors significantly affect parasitism: High relative humidity increased parasite prevalence, development rate, and load, while both low and high ...

Combined heat and drought affect the abundance, composition and diversity of subalpine surface‐active soil arthropod communities

open access: yesEcological Entomology, EarlyView.
We applied factorial soil warming and moisture reduction treatments directly in the field in the Australian subalpine to assess changes to surface‐active soil arthropod abundance, diversity and community composition. After identifying nearly 50,000 specimens to order, we found a stronger effect of sampling month than treatment.

Minimising insect mortality during grassland mowing: The potential of insect chasing devices

open access: yesInsect Conservation and Diversity, EarlyView.
Insect chasing devices have a great potential to deter arthropods prior to mowing, thereby reducing mortality. The effectiveness of mechanical flushing bars is limited and depends on driving speed, vegetation structure and species composition. The blowing device is the most independent of external factors and therefore the most effective.
