Osmoregulation in Insects

Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area. Malpighian tubules extend from the digestive tract, typically the area between the midgut and hindgut, into the hemolymph—a mixture of blood and interstitial fluid found in insects and other arthropods, as well as most...

Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.

What is Metabolism?

2019
Overview Metabolism represents all of the chemical activity in a cell, including reactions that build molecules (anabolism) and those that break molecules down (catabolism). Anabolic reactions require energy, whereas catabolic reactions provide it. Thus, metabolism describes how cells transform energy through a variety of chemical reactions, which are often made more efficient with the help of enzymes. Metabolism Is the Sum of All of the Chemical Reactions That Take Place in an Organism

Flight in insects is influenced by a number of factors and the propensity to disperse is an important variable in understanding insect ecology and biological control strategies. We describe the construction and use of a simple, relatively inexpensive, and flexible flight mill for measuring parameters of tethered flight in insects.

The capability to localize an odor source is necessary for insect survival and is expected to be applicable to artificial odor-tracking. The insect-controlled robot is driven by an actual silkmoth and enables us to evaluate the odor-tracking capability of insects through a robotic platform.
FAQs
Trehalose in the hemolymph serves as a circulating carbohydrate resource, helping deliver energy to tissues when demand changes. Its significance extends beyond storage: by linking nutrient availability with tissue energy use, it connects whole-insect physiology to local cellular needs. In neural contexts, this distribution supports the energetic requirements associated with ion gradients, synaptic transmission, and sensory or motor activity.
Hormonal and neuropeptide signals act as regulatory links between physiological state and biochemical activity. They can adjust metabolic pathways as conditions change, allowing energy processing to respond to demands associated with growth, movement, reproduction, or survival. This control is important because neural activity does not occur in isolation; signaling state and metabolism jointly shape how insects respond to changing internal or environmental conditions.
During neuronal activity, metabolism must support ion gradients and synaptic transmission, while sensory and motor functions create changing energy demands. The connection is therefore functional rather than merely anatomical: metabolic state can influence neural performance, and neural activity reflects the energetic needs of behavior. This framework helps explain why nutrition, stress, temperature, and development are relevant variables in insect neuroscience.
Research can examine insect metabolism alongside behavior and neural function under differing nutritional, stress-related, temperature, or developmental conditions. These comparisons help determine whether a change in behavior or neural performance accompanies altered metabolic demand or regulation. The approach is valuable because it connects biochemical pathways with observable outcomes, rather than treating metabolism and nervous-system activity as separate subjects.
In neuroscience, informative outcomes include changes in processes that depend on energy supply, such as neuronal ion gradients, synaptic transmission, and sensory or motor activity. Interpreting these outcomes alongside metabolic state can reveal how energy use supports neural function. It also provides a way to relate physiological changes to behavior when insects experience stress, altered nutrition, temperature shifts, or different developmental states.
Studying insect metabolism supports both comparative biology and pest-control research. Comparing metabolic regulation with neural and behavioral consequences can clarify how insects coordinate survival, movement, reproduction, and sensory responses. The same knowledge may identify metabolic processes relevant to controlling pest species, while preserving a broader view of how biochemical energy management relates to nervous-system function across insects.
