The greater wax moth, Galleria mellonella (L.) uses two different sensory modalities to evaluate the suitability of potential oviposition sites. | LitMetric

AI Article Synopsis

Article Abstract

An ovipositing insect evaluates the benefits and risks associated with the selection of an oviposition site for optimizing the fitness and survival of its offspring. The greater wax moth, Galleria mellonella (L.), uses beehives as an oviposition site. During egg-laying, the gravid wax moth confronts two kinds of risks, namely, bees and conspecific larvae. While bees are known to attack the moth's offspring and remove them from the hive, the conspecific larvae compete for resources with the new offspring. To date, little is known about the mechanisms involved in the assessment of oviposition site by the greater wax moth, G. mellonella (L.). Here, we demonstrate that the wax moth uses two different sensory modalities to detect risks to its offspring in the hives of Apis cerena. Bees appear to be detected by the contact-chemoreception system of the gravid wax moth, while detection of conspecifics relies on the olfactory system. Hence, our findings suggest that two different sensory modalities are used to detect two different risks to the offspring and that the selection of oviposition sites by G. mellonella (L.) relies on the integration of inputs from both the olfactory and contact-chemoreception systems.

Larvae of (the greater wax moth) are being increasingly used as a model to study microbial pathogenesis. In this model, bacterial virulence is typically measured by determining the 50% lethal dose (LD) of a bacterial strain or mutant. The use of to study pathogenesis, however, is challenging because of the extreme sensitivity of larvae to this bacterium.

This study analyzes the inhibitory effects of aqueous extract on infections and the immune response in larvae of the greater wax moth (Lepidoptera: Pyralidae). Larvae exhibited melanization within 1 h of being infected with inoculum at a concentration of 10 cells/larvae, and died within 24 h from a lethal dose.

Helicobacter pylori is a common Gram-negative bacterium that inhabits the human stomach and causes a variety of gastric pathologies. One of the growing concerns is its dynamic spread of antibiotic resistance, a process in which biofilm formation is involved. Therefore, it is necessary to find an appropriate, high-throughput research model for the in vivo biofilm development by H.
