The importance of alternative host plants as reservoirs of the cotton leaf hopper, Amrasca devastans, and its natural enemies [PDF]

, 2015
Many agricultural pests can be harboured by alternative host plants but these can also harbour the pests’ natural enemies. We evaluated the capacity of non-cotton plant species (both naturally growing and cultivated) to function as alternative hosts for ...

Of walls and floors: how physical structures affect mating song detection in stridulating orthopterans

Ecological Entomology, Volume 51, Issue 1, Page 141-152, February 2026.
Schematic representation of the experimental settings for one field type. Each setting was assigned one of the three treatments (i.e., walls, floors, or control). Each treatment contained an AudioMoth™ (circle), either positioned close to the ground (5 cm) or elevated (60 cm), acting as a receiver organism. Abstract Sensory ecology theory proposes that

Inhibition of Melanogenesis byXanthium strumariumL. [PDF]

Bioscience, Biotechnology, and Biochemistry, 2012
Xanthium strumarium L. (Asteraceae) is traditionally used in Korea to treat skin diseases. In this study, we investigated the effects of a X. strumarium stem extract on melanin synthesis. It inhibited melanin synthesis in a concentration-dependent manner, but it did not directly inhibit tyrosinase, the rate-limiting melanogenic enzyme, and instead ...
