Field experiments indicated that predators are an important source of mortality for tortoise beetle larvae in natural settings, and high larval mortality is associated with elevated densities of predators with piercing/sucking mouthparts, such as heteropterans. Thus, shields provide some but not ...
60. Each of these pests represents a unique feeding niche:A. craccivorainhabit the external surfaces of plants and use their piercing-sucking mouthparts to feed on phloem;L. trifoliilarvae live within the leaf tissues and feed internally; andS. littoralislarvae inhabit on the external surfaces of ...
Chemosensory genes are involved in many recognition processes in insects, among which host-plant detection and sexual communication19,20. Gustatory receptors (GRs) are expressed in taste sensilla on tarsi, ovipositors and mouthparts where they probably detect non-volatile molecules (e.g. sugars and ...
distribution patterns of scavenging amphipods in the Antarctic coastal ecosystems of Potter Cove. In Potter Cove, the climate-driven rapid retreat of the Fourcade Glacier is causing various environmental changes including the provision of new marine habitats to colonise. While in the newly ice-free ...
