Summary: The study revealed the rare phenomenon of deuterotokous parthenogenesis in seed beetles, where offspring from parthenogenesis can successfully reproduce and display similar characteristics as sexually produced offspring. This may stem from the biodiversity and genetic differentiation among the global distribution of the species.

Summary: This study aims to evaluate the effects of releasing different parasitoid species (Dinarmus basalis and Uscana lariophaga) on the populations of C. maculatus. The results show that the combined releases of both parasitoid species can better control the pest and significantly reduce seed losses during storage.

Summary: Theory predicts a positive relationship between egg load and foraging activity in insects. However, this study found that the relationship between foraging activity and egg load in parasitoid wasps may be secondary, primarily influenced by host patch quality.

Summary: The dilution effect and variability in parasitism risk have different impacts on the stability of host-parasitoid interactions. The study suggests that the dilution effect can increase CV2 and stabilize the dynamics of host-parasitoid systems.

Summary: The study aimed to enhance biological control measures for the serious pest Bagrada hilaris on brassica crops. By studying the egg parasitoid of B. hilaris found in Pakistan, it was found that the best combination of host egg and parasitoid age could be 0-1 day old host eggs with 3-10 day old parasitoids.

Summary: According to the study, cowpea and green gram were the most preferred hosts for the pulse beetle, C. maculatus, in terms of oviposition, survival rate, and developmental periods. On the other hand, red gram and soybean were less preferred hosts with lower oviposition rates. Cowpea and green gram also showed the highest grain damage and weight loss percentages after 120 days of insect inoculation.

Summary: This article evaluates the impact of random environmental fluctuations on the interaction between the sugarcane borer and its egg parasitoid, introducing a non-fragile control and impulsive biological control model to stabilize the situation. A new condition for exponential stability of the proposed population model is established using the Lyapunov method, with non-fragile controllers easily obtained through LMI solvers. Simulation studies based on the sugarcane borer system demonstrate the effectiveness and benefits of the proposed model.

Summary: The study investigated the bionomics of Callosobruchus maculatus in cowpea and common bean seeds in Nigeria, revealing differences in infestation rates, development, and damage between Vigna and Phaseolus genera. It was observed that the adults of C. maculatus do not feed and do not develop in common bean seeds, despite attempts using attractive seeds. The role of toxic metals like arsenic and minerals such as sodium, calcium, and potassium in affecting the bionomics of C. maculatus was highlighted, with implications for management strategies to control the pest.

Summary: The study investigated the color-changing behavior of phenoxazinone/phenoxazine pairs upon reduction using quantum chemical methods, proposing a mechanism involving electro-accepting power of auxochromes and their conjugation to facilitate intramolecular charge transfers. This ultimately leads to bathochromy.

Summary: The study introduced an optical measurement technique for coupled measurement of free surface topography and flow velocity beneath the surface, successfully applied to study three-dimensional flows. By 3D Lagrangian particle tracking velocimetry, accurate particle tracking was achieved, leading to the evaluation of energy balance and comparison of different sources of energy balance results.

Summary: Coloration is a complex trait involving physical and chemical processes at multiple levels, from molecules to tissues. Pigments, which absorb specific wavelengths of light, interact with molecular components in organelles to modulate color and reactivity. Integrative studies are needed to understand how pigments interact with their cellular environment and how they contribute to vivid and variable colors in animals.

Summary: Colors and patterns in nature are controlled by intracellular pigment-containing organelles within cells, representing important but often overlooked features of biological systems capable of coloration. Integrated and comparative studies offer insights into the morphology and function of pigment organelles across different scales and species, highlighting their significance in various biological contexts.

Summary: Pigment organelles of vertebrates, represented by melanosomes, belong to the lysosome-related organelle (LRO) family, but their catabolism remains poorly understood. By studying crab spiders, researchers found that pigment organelles share ultrastructural and chemical characteristics with LROs, and their catabolism likely involves intracellular degradation and removal of content through lysosomal mechanisms. This suggests that the endolysosomal system is fully functionalized for within-cell turnover of pigments, supporting the hypothesis of intracellular turnover of pigments originally formulated for human eye melanosomes.

Summary: Studies have shown that volatile substances emitted by Pseudomonas fluorescens strain MFE01 can inhibit the growth of Legionella pneumophila at a distance. This discovery highlights the potential of bacterial volatiles as potent anti-Legionella agents and suggests novel strategies for combating Legionella infections.

Summary: Environmental conditions can affect olfactory scent and chemical communication among species through the interaction of odorant molecules with aerosols. The study shows that pheromones can adsorb on aqueous aerosols when dispersed in air, but their residence time on pure water surfaces is short. The adsorption is influenced by factors such as entropy, enthalpy, structural arrangement, hydrogen bonding, and hydrophilic tail positioning.

Summary: This study explored the differences in bacterial diversity during the four developmental stages of the black soldier fly (BSF) using a metabarcoding approach. The results showed significant changes in bacterial community composition and species richness along the BSF life cycle, and identified nine prevalent core microbiota. The study also inferred 27 potential metabolic pathways differentially used among the BSF life cycle. This research provides a better understanding of metabolic processes during BSF development and their implications for bio-waste processing.

Summary: The purpose of this study was to identify and test new compounds from various Smoke Waters (SWs) samples for their impact on the key pest of olive production, Bactrocera oleae. Results showed that SWs obtained from different feedstocks could alter the fitness of B. oleae and affect its microbiome, as well as the behavior of adult flies.
