A widespread concern had been there regarding soil ecological and environmental problems caused by microplastic pollution in agricultural soils. A controlled laboratory incubation experiment was performed to examine the effects of different types of microplastics on soil properties, NO emissions, and nitrogen (N) transformations in tropical arable soils from a pepper-corn cropping system in Hainan Province. Three treatments were done: soil without microplastics (CK) and soil amended with 5% of polyethylene (PE) or with 5% of polybutylene adipate co-terephthalate (PBAT).

Influence of Temperature and Host Plant on the Digestion of (Trybom) Revealed by Molecular Detection.

Insects

October 2024

Key Laboratory of Integrated Pest Management on Tropical Crops, Ministry of Agriculture and Rural Affairs, Environment and Plant Protection Institute, Chinese Academy of Tropical Sciences, Haikou 571101, China.

(Trybom) (Thysanoptera: Thripidae) is an important type of thrip and a polyphagous pest, which poses a serious threat to many crops, especially those in tropical regions of China. Its feeding behavior and the damage caused vary among different host plant species and are affected by ambient temperature and plant nutrients as well. The digestion rate is an important index for directly observing the digestion process, but there have been no studies directly measuring the digestion in thrips under the influence of different temperatures and host plants.

Article Synopsis
  • The study focuses on the parasitoid Compere, a natural enemy of the rubber tree pest Nietner, and investigates how high temperatures affect its survival and reproductive capabilities.
  • Short-term high-temperature exposure (36 °C, 38 °C, and 40 °C) leads to reduced survival, delayed development, and lower egg production in Compere, with effects worsening as temperatures and durations increase.
  • Continuous exposure to temperatures like 34 °C significantly impacts Compere’s life span and reproductive success, highlighting temperature thresholds critical for maintaining the pest's biological control efficiency.

State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing, China.

How organisms respond to complex environments is one of the unsolved problems in ecology. Life history patterns of a species provide essential information on how different populations may respond and adapt to environmental changes. Compared to typical seasonal breeders, which have limited distributions, the worldwide distribution of brown rats (Rattus norvegicus) across highly complex and divergent habitats suggests they exhibit exceptional adaptiveness.

The presence of pathogenic bacteria and antibiotic resistance genes (ARGs) in urban air poses a significant threat to public health. While prevailing research predominantly focuses on the airborne transmission of ARGs by bacteria, the potential influence of other vectors, such as bacteriophages, is often overlooked. This study aims to investigate the characteristics of phages and ARGs in aerosols originating from hospitals, public transit centers, wastewater treatment plants, and landfill sites.

Article Synopsis
  • Exposure to pathogens can trigger behavioral changes that influence the spread of diseases, with healthy individuals practicing social distancing and infected individuals potentially isolating themselves.
  • In a study of agile frog juveniles, both healthy and infected frogs avoided mingling with infected peers, which may help reduce disease transmission.
  • However, infected frogs did not show self-isolation, which could allow the disease to spread further; more research is needed to understand these dynamics in amphibians.

Article Synopsis
  • The invasive pest Liriomyza trifolii threatens ornamental and vegetable plants, spreading quickly and demonstrating high heat resistance.
  • Researchers created strains of this pest adapted to high temperatures (35°C and 40°C) to study their survival and reproductive behaviors under thermal stress.
  • Findings revealed that while acclimation at 35°C boosted reproduction and population growth, the 40°C strain had faster development but lower reproductive success, indicating a balance between adaptability and reproduction under environmental stress.

Moisture is the most important environmental factor limiting seed regeneration of shrubs in desert areas. Therefore, understanding the effects of moisture changes on seed germination, morphological and physiological traits of shrubs is essential for vegetation restoration in desert areas. In March to June 2023, in a greenhouse using the potting method, we tested the effects of soil moisture changes (5%, 10%, 15%, 20% and 25%) on seed germination and seedling growth of six desert shrubs (, , , , , and ).

Thaumatin-like proteins (TLPs) in plants play a crucial role in combating stress, and they have been proven to possess antifungal properties. However, the role of TLPs in pathogens has not been reported. We identified a effector protein, Pt9029, which contained a Thaumatin domain in Puccinia triticina (Pt), possessing a chloroplast transit peptide and localized in the chloroplasts.

The introduction of the Nearctic predaceous stink bug species, (Perillus bioculatus) was attempted multiple times in various countries throughout Europe to mitigate the damage caused by the invasive and harmful pest species, the Colorado potato beetle (Leptinotarsa decemlineata). Though these attempts were thought to be unsuccessful for decades, more recent data elucidated that the species have established small self-sustaining populations in the Balkans Peninsula, Southern Russia, and Türkiye and recently began to expand. In the past years, the European range of the species reached Eastern Europe.

Cadmium (Cd) exhibits widely olfactory toxicity to animals. We previously reported that Cd exposure induces the transcriptional dysregulation of olfactory marker proteins (OMPs) of the red imported fire ant Solenopsis invicta. However, it is still unclear how environmental Cd exposure-induced deregulation of OMPs affects the olfactory signal transduction and olfaction-driven social behavior of S.
