Temperature‐dependent interspecific interference alters pygmy backswimmer predation on water fleas

open access: yesEcological Entomology, EarlyView.
Increasing densities of water mites alter the predation behaviour of pygmy backswimmer, particularly in higher temperatures. Pygmy backswimmer displayed type II functional response across all the treatments. In the absence of water mites, the functional response was higher at 25°C than at 16°C, indicated by a higher space clearance rate.

Leveraging Biodiversity Net Gain to address invertebrate declines in England

open access: yesInsect Conservation and Diversity, EarlyView.
Biodiversity Net Gain (BNG) is a new approach to infrastructural development in England, mandating that developers achieve a 10% BNG by enhancing and creating habitats. As currently implemented, BNG risks creating smaller, homogeneous, structurally simple and poorly connected habitats.

Transmission efficiency of the plague pathogen (Y. pestis) by the flea, Xenopsylla skrjabini, to mice and great gerbils

open access: yesParasites & Vectors, 2015
Background Plague, a zoonotic disease caused by Yersinia pestis, is characterized by its ability to persist in the plague natural foci. Junggar Basin plague focus was recently identified in China, with Rhombomys opimus (great gerbils) and Xenopsylla ...

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.

Effective target genes for RNA interference‐based management of the cabbage stem flea beetle

open access: yesInsect Molecular Biology, EarlyView.
An oral RNAi screen consisting of 27 dsRNAs identified effective target genes for RNAi‐based pest control in the cabbage stem flea beetle The most effective target genes were involved in proteasomal pathways or gene expression, and their sequences were subjected to in silico off‐target analysis Knock‐down of some effective target genes also inhibited ...

The quest for the best target genes for RNAi‐mediated pest control

open access: yesInsect Molecular Biology, EarlyView.
A major challenge for RNAi mediated pest control is the identification of the most effective RNAi target genes from the pool of ~37% of all genes that are essential. Effective RNAi target genes are predominantly highly conserved genes serving basic cellular functions such as protein degradation.

Testing non‐lethal techniques for endoparasite detection and sex determination in pumpkinseed sunfish (Lepomis gibbosus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound

Steroid‐responsive generalised sterile necrotising pyogranulomatous lymphadenitis in a cat

open access: yesJournal of Small Animal Practice, EarlyView.
A 1.5‐year‐old neutered male cat was presented with fever, inappetence, lethargy and marked generalised lymphadenopathy of 4 days duration. Excisional biopsy of peripheral lymph nodes revealed necrotising pyogranulomatous lymphadenitis. Extensive investigation failed to identify an underlying infectious [bacterial (Bartonella, Mycobacteria, Mycoplasma,
