“…An example of a simple static algorithm is the Round-Robin algorithm. In this resource scheduling method, tasks are served in the order they arrive, and the least-loaded resource is allocated to complete the tasks based on time sharing principles [18]. b) Dynamic load balancing: In this environment despite the need for prior, like static environment, the algorithms operate according to the run-time statistics.…”

Load balancing plays a critical role in optimizing resource utilization and enhancing performance in cloud computing systems. As cloud environments grow in scale and complexity, efficient load balancing mechanisms become increasingly vital. This paper presents a comprehensive review of load balancing techniques in cloud computing systems, with a focus on their applicability, advantages, and limitations. The review encompasses both static and dynamic load balancing approaches, evaluating their effectiveness in addressing the challenges posed by cloud infrastructure, such as heterogeneity, scalability, and variability in workload demands. Furthermore, the review examines load balancing algorithms considering factors such as resource utilization, response time, fault tolerance, and energy efficiency. Additionally, the impact of load balancing on cloud performance metrics, including throughput, latency, and scalability, is analyzed. This review aims to provide insights into the state-of-the-art load balancing strategies and serve as a valuable resource for researchers, practitioners, and system designers involved in the development and optimization of cloud computing systems.

“…Insects can also increase the expression of their detoxification enzymes, especially those within the cytochrome P450 monooxygenase (P450), glutathione- S -transferase (GST), and carboxylesterase families and superfamilies of enzymes for developing insecticide resistance and adapting to toxic environments [ 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. These enzymes can be upregulated by several signaling pathways in insects, most notably the AhR/ARNT or xanthotoxin cascade, the CncC/Keap1 pathways, and the MAPK/CREB pathway.…”

“…The interactions between insects and the toxic chemicals, both naturally occurring and synthetic, can be complicated, especially as many insects depend on microbial symbionts, such as their gut bacterial symbionts, to aid in toxin degradation [ 34 , 35 , 36 , 37 ]. The role of these symbionts in insect growth, health, and activity is still not fully understood, but it is apparent that microbes are capable of detoxifying many xenobiotics and conferring resistance on several insect species [ 37 , 38 , 39 , 40 , 41 ]. Understanding these interactions and how insects cope with the exposure to toxins can further our knowledge into how pest species develop resistance to insecticides and how to better protect beneficial insect species from exposure and harmful effects.…”

Insects are the most diverse form of life, and as such, they interact closely with humans, impacting our health, economy, and agriculture. Beneficial insect species contribute to pollination, biological control of pests, decomposition, and nutrient cycling. Pest species can cause damage to agricultural crops and vector diseases to humans and livestock. Insects are often exposed to toxic xenobiotics in the environment, both naturally occurring toxins like plant secondary metabolites and synthetic chemicals like herbicides, fungicides, and insecticides. Because of this, insects have evolved several mechanisms of resistance to toxic xenobiotics, including sequestration, behavioral avoidance, and enzymatic degradation, and in many cases had developed symbiotic relationships with microbes that can aid in this detoxification. As research progresses, the important roles of these microbes in insect health and function have become more apparent. Bacterial symbionts that degrade plant phytotoxins allow host insects to feed on otherwise chemically defended plants. They can also confer pesticide resistance to their hosts, especially in frequently treated agricultural fields. It is important to study these interactions between insects and the toxic chemicals they are exposed to in order to further the understanding of pest insect resistance and to mitigate the negative effect of pesticides on nontarget insect species like Hymenopteran pollinators.

“…To isolate gut bacteria, 7-day-old mixed-sex adult T. castaneum were starved for 1 d, then surface disinfected with 70% alcohol, and subsequently rinsed thrice with aseptic water. Gut bacteria were excised and purified as previously described [14]. The purified gut bacteria were collected and preserved in Luria-Bertani (LB) broth added with 25% glycerine at −80 • C for subsequent assays.…”

Knowledge about resistance mechanisms can provide ideas for pesticide resistance management. Although several studies have unveiled the positive or negative impacts of gut microbes on host pesticide resistance, minimal research is available regarding the association between gut microbes and host phosphine resistance. To explore the influence of gut bacteria on host phosphine susceptibility and its molecular basis, mortality, fitness, redox responses, and immune responses of adult Tribolium castaneum were determined when it was challenged by phosphine exposure and/or gut bacteria inoculation. Five cultivable gut bacteria were excised from a population of phosphine-resistant T. castaneum. Among them, only Enterococcus sp. inoculation significantly promoted host susceptibility to phosphine, while inoculation of any other gut bacteria had no significant effect on host phosphine susceptibility. Furthermore, when T. castaneum was exposed to phosphine, Enterococcus sp. inoculation decreased the female fecundity, promoted host oxidative stress, and suppressed the expression and activity of host superoxide dismutase, catalase, and peroxidase. In the absence of phosphine, Enterococcus sp. inoculation also elicited overactive immune responses in T. castaneum, including the immune deficiency and Toll signaling pathways and the dual oxidase–reactive oxygen species system. These results indicate that Enterococcus sp. likely promotes host phosphine susceptibility by aggravating oxidative stress and fitness costs.
