Summary: Tiger beetles are important predators in turfgrass in Georgia, USA. Bifenthrin and imidacloprid are commonly used insecticides in turfgrass, but lower doses of bifenthrin can alter the hunting behavior of tiger beetles while lower doses of imidacloprid do not cause any changes. It is important for turfgrass managers to check for the presence of tiger beetle holes before using insecticides.

Summary: The study aimed to investigate whether imidacloprid could cross the blood-brain barrier in adult Northern Leopard frogs exposed to different concentrations, with results showing significantly higher concentrations in the brain of exposed groups compared to the control. Additionally, a dose-response relationship was observed with breakdown products and imidacloprid brain concentrations, indicating that imidacloprid can bioaccumulate in amphibian brains. Behaviorally, exposure to imidacloprid resulted in slower reaction times to food stimuli, with a positive correlation between response time and imidacloprid brain concentration.

Summary: Food security is a global concern, and aquaculture plays an important role in meeting the global food demand. Disease outbreaks in shrimp aquaculture, particularly white spot disease caused by the white spot syndrome virus, have been a major issue. Antibiotics have been used to control the disease, but their accumulation in food webs has adverse effects on humans. Immunostimulants have been identified as a more eco-friendly alternative, enhancing the shrimp's immune system. Proper sanitation procedures combined with the use of immunostimulants may be a viable approach for preserving shrimp aquaculture worldwide.

Summary: Shrimp production is a rapidly growing aquaculture sector valued at around USD 18.30 billion in 2020, but intensified culture leads to outbreaks of transmissible diseases causing huge economic losses. Studies show that shrimp miRNA plays a critical role in host-pathogen interactions, enhancing host immunity against viral infection while also aiding viral replication and infection. This dual role of shrimp miRNA highlights its potential for both strengthening shrimp culture against viruses and contributing to the complexity of shrimp infection mechanisms.

Summary: This study compares the solubility of nine forms of copper in soils and finds that the complexation of copper with soil phases is the main process determining solubility, while dissolution limits the increase of soluble copper in the form of nanoparticle. Soil pH and organic carbon content affect the dissolution kinetics and equilibrium concentration of copper. The proportion of readily available copper is very low in the short term. Soil moisture content has a significant impact on the measured soluble copper.
