Written by Andrew E. Sharma   Published on Vol 3 Issue 2, 2023
Arsenic has become a significant concern due to its detrimental effects on public health across various regions globally. Both natural and human-made sources contribute to groundwater contamination, leading to arsenicosis, which adversely affects ecosystems and human health. The trivalent form of inorganic arsenic is particularly harmful because it is neurotoxic and capable of crossing the blood-brain barrier. This exposure poses substantial health risks, particularly to the central nervous syst

Written by Juan X. Schneider   Published on Vol 3 Issue 2, 2023
The insect production industry is expanding rapidly across the globe, offering an effective approach to recycling organic waste. One of the most important by-products of this process is insect feces, commonly referred to as ‘frass.’ Since frass is generated in larger quantities than the insects themselves, its use is essential to promote a sustainable circular economy. This research focused on assessing the feasibility of employing frass from yellow mealworms (Tenebrio molitor) as a fertilizer.

Written by Kenji Fernandez   Published on Vol 3 Issue 2, 2023
The parasitism of livestock by ixodid ticks, which transmit blood-borne parasitic diseases, is a major challenge in animal husbandry. This research focuses on how climate change affects the diversity of ixodid tick species. Data from the Kislovodsk meteorological station, including average winter temperature, wind speed, and the variability and trends of the Bodman index (which indicates climate severity), were analyzed. The distribution of ixodid ticks is closely tied to the climatic zones. In

Written by Nguyen Thanh Huy   Published on Vol 3 Issue 2, 2023
Insect species complexes are often treated as delimitation problems whose endpoint is a set of species boundaries. That framing collapses distinct inferential tasks and can obscure whether an observed signal represents overlooked species, population structure, hybridization, marker-specific resolution, a legacy naming problem, or merely an identification problem. This article develops a stage-based taxonomic architecture separating discovery, hypothesis generation, delimitation, independent vali

Written by Fatima El Idrissi   Published on Vol 3 Issue 2, 2023
Juvenile hormone (JH), ecdysteroids, and insulin/IGF-like signaling (IIS) are often described as separable endocrine systems controlling insect development, metabolism, and reproduction. Evidence from selected insects instead reveals regulatory connections among these systems, but it does not support a single invariant endocrine cascade. This article develops an original molecular-physiological synthesis in which JH, ecdysteroid, and IIS components form a proposed conditionally reconfigurable re

Written by Laura Keller   Published on Vol 3 Issue 2, 2023
Oxidative physiology is frequently invoked to explain insect responses to environmental stress, aging, and reproductive investment, yet the underlying evidence does not support a single continuum in which reactive oxygen species invariably represent damage, greater antioxidant activity invariably represents protection, or reproduction necessarily reduces somatic maintenance. This article develops a proposed physiological model in which oxidative balance is treated as a dynamic analytical state e

Microbiome–Host Signaling Produces Nutritional, Immune, and Developmental Effects Only Under Specific Biological and Environmental Conditions

Written by David Thompson   Published on Vol 3 Issue 2, 2023
Insect microbiomes are often discussed as if microbial presence itself predicts host nutritional, immune, or developmental benefit. That interpretation is too coarse for the available evidence. This molecular perspective argues that host phenotype is better understood as the outcome of conditional signaling: microbes must occupy an appropriate niche, generate or transform a biologically relevant signal, encounter a responsive host pathway, and do so within a nutritional, developmental, genetic,

Written by George Wilson   Published on Vol 3 Issue 2, 2023
Climate variability is changing the timing of insect development, diapause, emergence, flight, and species interactions, but phenological responses cannot be interpreted reliably as simple advances under warming. This systematic review synthesizes evidence published from 2017–2023 to distinguish environmental cues from biological responses, phenotypic plasticity from evolutionary differentiation, and altered timing from ecological consequence. Temperature-sensitive development can translate ther

Written by Elena Fedorova   Published on Vol 3 Issue 2, 2023
Chemical communication in insects is often described as if signal production, environmental transmission, detection, neural processing, and behavioral response formed one continuous and self-evident causal chain. Evidence across insect taxa instead shows that each transition has distinct biological constraints and distinct evidential requirements. This integrative review examines how chemical signals are generated, released into heterogeneous environments, detected by peripheral chemosensory sys

Written by Michael Roberts   Published on Vol 3 Issue 2, 2023
Phylogenomics has transformed insect systematics by expanding the number and genomic distribution of characters available for species delimitation, yet greater data volume does not remove the assumptions that connect sampled organisms to taxonomic conclusions. This methodological review examines that inferential chain across sampling design, locus and genome representation, species-tree models, gene flow, delimitation algorithms, threshold and prior sensitivity, and reproducibility.

Views: 145
Written by Marco De Luca   Published on Vol 3 Issue 2, 2023
Insect stress physiology is often interpreted upward across biological scales: molecular induction is treated as protection, protection as improved performance, and improved performance as evidence of fitness benefit or adaptation. The available evidence does not justify that sequence as a default. This critical review evaluates how inference changes from molecular stress signaling through cellular, tissue and organ responses to whole-animal performance, survival and reproduction.

Written by Aisha Bello   Published on Vol 3 Issue 2, 2023
Host-associated differentiation is frequently interpreted as an early stage of ecological speciation, but the evidential steps between host use, population divergence, reproductive isolation, restricted gene flow, and species-level divergence are not interchangeable. This systematic evidence map organizes recent insect literature according to what each evidence class can actually establish. The mapped studies span phylogenetic, population-genomic, ecological, phenological, behavioral, reproducti
