Summary: This study assessed the acute and sub-chronic toxic effects of Triphenyl phosphate (TPhP) on amphibians. The results showed that TPhP concentrations significantly affected the survival, metamorphosis rate, and metamorphosis time of tadpoles. However, no significant changes were observed in the condition factor and hepatic somatic index after metamorphosis, but tadpole body mass was negatively correlated with TPhP concentration.

Summary: The study revealed significant differences in microbial communities on healthy and ulcerated Hoplobatrachus rugulosus skin, indicating changes in bacterial proportion and type may be caused by skin ulceration. This information could be valuable in developing strategies to combat diseases in H. rugulosus.

Summary: The tiger frog is a protected species in China. This study identified key genes related to gonadal development in amphibians using Illumina HiSeq 3000 sequencing, laying the foundation for future research. Significant differences in gonadal gene expression levels in male and female tiger frogs were found.

Summary: We examined the levels of As, Cr, Cd, and Pb in farmed East Asian bullfrog samples from Vietnam and Thailand using ICP-MS. The results showed high levels of As, with no significant differences between production areas. Cd was not detected in any of the samples, and the Pb concentrations were within the permitted levels set by the European Commission. The Cr and Pb contents were higher in bullfrogs produced in Vietnam compared to Thailand. The consumption of this type of food may pose carcinogenic and non-carcinogenic risks due to the elevated levels of As.

Summary: This study investigated the effectiveness of four insecticides for controlling Plutella xylostella and their effects on Cycloneda sanguinea. The results showed that spinosad and chlorfenapyr were highly toxic to P. xylostella, while chlorantraniliprole and methomyl were ineffective. Chlorantraniliprole was highly toxic to C. sanguinea, while methomyl and chlorfenapyr were toxic to C. sanguinea when ingested. Spinosad had low toxicity to C. sanguinea, but affected its flight behavior.

Summary: The study found that Lindane insecticide has significant acute toxicity effects on the intestinal tissues of immature grass carp, causing tissue lesions and abnormal behaviors. Increasing concentrations of Lindane have more severe impacts on the behavior and health of fish.

Summary: This study found that about 65% of live edible Chinese frogs collected from wet markets in Hong Kong were carriers of Salmonella, including multiple serotypes. The study also identified a number of antimicrobial resistance genes and virulence determinants, as well as 21% of the isolates being multidrug-resistant. Therefore, public health measures should be implemented to mitigate the risk of Salmonella transmission to humans through handling edible frogs.

Summary: Agricultural production and the use of insecticides pose risks to the biodiversity and ecosystem services provided by bees. This study focused on the effects of the insecticide thiamethoxam on the stingless bee Plebeia catamarcensis. The study found that thiamethoxam can have lethal and sublethal effects on the bees, impacting their mobility and potentially leading to population decline.

Summary: The research demonstrates that the sex determination system of the rice field frog is temperature-dependent, with a highly conserved karyotype and lack of sex chromosome heteromorphism. These findings provide valuable insights into the understanding of the mechanism of sex determination in H. rugulosus.

Summary: The insecticide methomyl can cause high mortality of the dusky slug, Arion subfuscus, on corn plants, but poor control outcomes in field operations are likely due to the high ambient moisture levels that reduce the toxicity of methomyl residues and lessen the repellency of treated plants to slugs.

Summary: This study uncovered the differences in mitochondrial gene expression between Chinese tiger frogs and Thai tiger frogs under low temperature conditions. The structural and expression differences in the ND5 gene between the two subspecies may result in their different tolerances to low temperature stress. Most of the mitochondrial protein-encoding genes were down-regulated at low temperatures, which could significantly reduce the metabolic rate and support long-term survival. The expression pattern of mitochondrial genes in different organs was related to mitochondrial activity and mtDNA replication.

Summary: The study isolated Xanthomonas campestris pv. Translucens and Aspergillus fumigatus as microbial isolates capable of degrading dimethoate and methomyl residues in water. These isolates showed fast growth and degradation rates in water spiked with pesticides, with up to 97.8% and 91.2% of dimethoate, and 95% and 87.8% of methomyl being biodegraded within 32 days. Toxicity tests on rats confirmed the absence of remaining toxicity after treatment with these microbial isolates, indicating their high potential for complete degradation of pesticide residues.

Summary: This study investigated the steroidogenic potential of the gonads in the rice field frog. The expression levels of CYP17 and CYP19 mRNA were analyzed in males and females at different stages of development. The results showed a sexual dimorphic pattern in steroidogenic potential, with CYP17 mRNA being higher in males and localized in the Leydig cells of the testis, while CYP19 mRNA was higher in females and correlated with gonadal development in the ovary.

Summary: This study investigates the effects of acute arsenic treatment on the behavior, cognition, and development of Drosophila. The findings suggest that arsenic exposure significantly affects locomotor abilities, pupae size, cognitive functions, and neurobehavioral impairment in fruit flies, providing insights into the mechanisms of arsenic toxicity on the brain.
