Understanding the epigenetic molecular mechanisms (EMMs) of reproduction is crucial for developing advanced and targeted control strategies for Spodoptera frugiperda. Differential expression analysis revealed 11 known miRNAs with varying expression levels, including nine upregulated and two downregulated miRNAs, in virgin females compared with males. The predictive analysis identified 426 target genes for these miRNAs, with ribogenesis highlighted as a key process in oogenesis and egg fertilization.

Preeclampsia is associated with an increased risk of long-term cardiometabolic disease; however, little is known regarding metabolic factors in the early postpartum years potentially contributing to these health disparities. This study aimed to compare body composition, serum biochemical parameters, energy balance and diet 6 months and 2 years after normotensive pregnancy versus preeclampsia. This is the longitudinal metabolic sub-study of the Postpartum Physiology, Psychology and Paediatric cohort study.

Insecticide resistance is a global concern and requires immediate attention to manage dreadful insect pests. One of the resistance mechanisms adopted by insects is through ATP-binding cassette (ABC) transporter proteins. These proteins rapidly transport and eliminate the insecticidal molecules across the lipid membranes (Phase III detoxification mechanism).

Article Synopsis
  • The study introduces a new species called Goniozus apoderophagus, a type of wasp (Hymenoptera, Bethylidae).
  • This wasp functions as an ectoparasitoid, meaning it feeds on a host, specifically the beetle Apoderus tranquebaricus, which is found in leaf rolls of the plant Grewia abutilifolia in Karnataka, India.
  • The researchers also compare this new species with other similar species found in the Oriental region to highlight its unique characteristics.

Bacillus thuringiensis Berliner is recognized as a predominant bioinsecticide but its antifungal potential has been relatively underexplored. A novel B. thuringiensis strain NBAIR BtAr was isolated and morphologically characterized using light and scanning electron microscopy, revealing presence of bipyramidal, cuboidal, and spherical parasporal crystals.

Maconellicoccus hirsutus is a highly polyphagous insect pest, posing a substantial threat to various crop sp., especially in the tropical and sub-tropical regions of the world. While extensive physiological and biological studies have been conducted on this pest, the lack of genetic information has hindered our understanding of the molecular mechanisms underlying its growth, development, and xenobiotic metabolism.

Matile-Ferrero (Hemiptera: Pseudococcidae), is an economically important invasive cassava pest responsible for the massive devastation of cassava in Asia and African continent. Initially, identifying this invasive pest posed challenges because it closely resembled native mealybug species. Additionally, the traditional morphological identification process is labor-intensive and time-consuming.

Nanoparticle-based delivery systems have emerged as powerful tools in the field of pest management, offering precise and effective means of delivering double-stranded RNA (dsRNA), a potent agent for pest control through RNA interference (RNAi). This comprehensive review aims to evaluate and compare various types of nanoparticles for their suitability in dsRNA delivery for pest management applications. The review begins by examining the unique properties and advantages of different nanoparticle materials, including clay, chitosan, liposomes, carbon, gold and silica.

Article Synopsis
  • - Chitosan is a natural biopolymer with strong properties that can be turned into nanopowder for agricultural use, improving the effectiveness of existing agrochemicals by enhancing solubility and controlling release.
  • - Studies have shown that chitosan nanopowder can boost a plant's defenses against pests and diseases, while raising concerns about potential toxicity, leading researchers to investigate its effects on egg parasitoids like Ashmead.
  • - Statistical analysis indicated that eggs exposed to chitosan nanopowder had higher rates of parasitization compared to controls, suggesting chitosan may positively influence pest management in agriculture through enhanced biological activity.

A series of experiments were carried out to determine the acute toxicity of pesticides in the laboratory, toxicity through spray on flowering plants of mustard (Tier II evaluation) and field on both Apis cerana and A. mellifera bees. The overall mortality of honey bees through topical (direct contact) were found significantly higher than that of indirect filter paper contamination assays.

Activated red mud (ARM) samples were tested for carbon monoxide (CO) oxidation in the temperature range of 100-500°C. Conversion of >90% was obtained for temperatures above 400°C for all samples. In order to study the effect of hydroxylated phases of iron oxide in red mud on the removal of CO, 'as-received' red mud (RM) and acid digested and re-precipitated red mud (TRM) were also tested under similar conditions.

A characterization study detailing the phase transformations and microstructural nature of the carbon deposited during methane decomposition over red mud has been undertaken. In situ XRD was carried out to study the phase transformation sequences of red mud during the reaction. Scanning electron microscopy, high resolution transmission electron microscopy, thermogravimetric analysis, BET surface area determination and CHN analysis were carried out to investigate the properties of the post-reaction samples.
