Chromosome localization of the gene controlling the stress response of DFP-sensitive juvenile hormone (JH) esterase in females of Drosophila virilis was conducted. Line 160 of D. virilis carrying recessive markers on all chromosomes was used as a tester. Mature females of line 160 were shown to exhibit a high level of JH hydrolysis; these flies responded to stress by a sharp decrease in JH hydrolysis. Flies from line 147 lacked this response. Thus, mature females of lines 160 and 147 had different levels of JH hydrolysis under heat stress. F2 hybrids that inherited one chromosome pair from flies of line 147 and the remaining chromosomes, from flies of line 147 were analyzed. This analysis showed that the D. virilis gene controlling the stress response of the JH degradation system is linked with chromosome 6.

Salmonella is one of the most common foodborne pathogens. Antimicrobial-resistant Salmonella isolates, especially those resistant to colistin, pose a significant threat to public health worldwide. However, data about the prevalence of mcr-positive Salmonella in animals was few and the dissemination of mcr-positive Salmonella from animals to food, especially eggs, has not been fully addressed.

Article Synopsis
- Tularemia, caused by the bacterium Francisella tularensis, poses a significant threat to human health but lacks extensive data on its distribution in blood-feeding arthropods.
- A study conducted in the Břeclav district in 2022 screened various hematophagous vectors, including ticks, mosquitoes, and blackflies, to check for the presence of this bacterium.
- The results revealed only two positive samples for F. tularensis subsp. holarctica, both from the tick species Dermacentor reticulatus, while no presence was found in mosquitoes or blackflies.

Phlebotomine sand flies are the vectors of leishmaniasis, a neglected tropical disease. High-quality reference genomes are an important tool for understanding the biology and eco-evolutionary dynamics underpinning disease epidemiology. Previous leishmaniasis vector reference sequences were limited by sequencing technologies available at the time and inadequate for high-resolution genomic inquiry.

Article Synopsis
- - Animal trypanosomosis is a major livestock disease in Ethiopia, affecting animal productivity and transportation, and this study assesses its prevalence and related factors in the Sidama region across different seasons.
- - The study involved analyzing blood samples from 964 cattle and using NGU traps for tsetse fly investigations, revealing an overall trypanosomosis prevalence of 9%, with notable variations between districts and coat colors of the cattle.
- - Results indicated that infected cattle had significantly lower packed cell volume (PCV) compared to uninfected ones, and the majority of infections were caused by Trypanosoma congolense, highlighting the disease's impact on livestock health and productivity.

The demand for sustainable and ethically farmed animal products is on the rise as consumers become more environmentally and animal welfare conscious. The need to diminish the consumption of soybean meal is urgent, and companies are looking for ways to respond to this necessity by looking for alternatives to soybean meal. This study assessed the impact of introducing whole dehydrated and live black soldier fly larvae (BSFL) into the diet of an indigenous chicken breed as environmental enrichment.
