Response of Amblyseius swirskii to deltamethrin.

Background: The rising demand for environmentally friendly pest control highlights the importance of understanding the interaction between natural enemies and pesticides. Amblyseius swirskii, a predatory mite extensively used in biocontrol, plays a crucial role in managing pest populations in agricultural systems. Integrating this mite with selective pesticide use within integrated pest management (IPM) would significantly advance pest control and may reduce pesticide residues in the environment and agricultural produce.

The dispersion method does not affect the in vitro genotoxicity of multi-walled carbon nanotubes despite inducing surface alterations.

Multi-walled carbon nanotubes (MWCNTs) are a desirable class of high aspect ratio nanomaterials (HARNs) owing to their extensive applications. Given their demand, the growing occupational and consumer exposure to these materials has warranted an extensive investigation into potential hazards they may pose towards human health. This study utilised both the in vitro mammalian cell gene mutation and the cytokinesis-blocked micronucleus (CBMN) assays to investigate genotoxicity in human lymphoblastoid (TK6) and 16HBE14o human lung epithelial cells, following exposure to NM-400 and NM-401 MWCNTs for 24 h.

Moisture-dependent pupation of the invasive thrips Chaetanaphothrips orchidii: implications for its management.

Background: Chaetanaphothrips orchidii is an invasive thrips of tropical origin that was detected in 2016 in Spanish citrus, where it can damage up to 70% of the fruit. Pupation site and emergence rates are key biological traits for thrips management that are unknown for C. orchidii.

Impact of semen cryopreservation season on in vitro embryo production of prepubertal goat oocytes.

Goat production is affected by reproductive seasonality. In vitro embryo production (IVEP) could overcome this effect. This study aimed to evaluate the impact of the season of semen collection/freezing on IVEP of prepubertal goat oocytes and on sperm quality and functionality concerning capacitation.

The SAM-Krom biomonitoring study shows occupational exposure to hexavalent chromium and increased genotoxicity in Denmark.

Background: Hexavalent chromium (Cr(VI)) is a carcinogen. Exposure to Cr(VI) may occur in different industrial processes such as chrome plating and stainless steel welding. The aim of this study was to assess occupational exposure to Cr(VI) in Denmark.
