, commonly known as the Portuguese Man o' War, is one of the most venomous members of the Cnidaria yet is poorly understood. This article investigates the toxicity of venom by assessing its behavioral and toxicological effects on . The venom administered orally revealed dose- and time-dependent mortality, with an LD50 of 67.

is a pest of global concern due to its great impact on several crops. The entomopathogenic nematode was highly virulent to the larvae of the fly although some immune mechanisms were triggered along the infection course. Thus, to understand the gene activation profile we performed a comparative transcriptome of larvae infected with and to map the differentially expressed genes involved in the defence response.

Entomopathogenic nematodes (EPNs) are closely associated with and potentially used as their biological control agents, although field results proved inconsistent and evoked a continual pursuit of native EPNs more adapted to the environment. Therefore, we surveyed the Azorean Archipelago to isolate new strains of and to evaluate their virulence against the model organism under laboratory conditions. Six strains were obtained from pasture and coastal environments and both nematode and symbiont bacteria were molecularly identified.

Article Synopsis
  • The Japanese beetle, an invasive pest native to Japan, poses a threat to various crops and has spread across North America and parts of Europe.
  • Researchers sequenced the complete mitochondrial genome of 86 beetles to understand their origins and invasions better, revealing significant genetic differences between populations in South and Central/North Japan.
  • The study indicates that there were multiple introductions of these beetles into the USA and Europe, with subsequent population expansions and contractions, allowing for the estimation of invasion timelines and changes in population dynamics.
