We present a novel surgical procedure to implant electrodes in Manduca sexta during its early metamorphic stages. This technique allows mechanically stable and electrically reliable coupling with the neuromuscular tissue to study flight neurophysiology dynamics. We also present a novel magnetic levitation platform for tethered studies of insect yaw.

Oral and intra haemocolic infection of larvae of the greater wax moth Galleria mellonella is described. This insect can be used to study virulence factors of entomopathogenic as well as mammalian opportunistic bacteria. Rearing of the insects, methods of infection and examples of in vivo analysis are described.

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...

Life tables allow quantification of the sources and rates of mortality in insect populations and contribute to understanding, predicting and manipulating population dynamics in agroecosystems. Methods for conducting and analyzing cohort-based life tables in the field for an insect with sessile immature life stages are presented.
FAQs
Survival curves show how mortality accumulates across the observation period rather than reducing the outcome to a single final count. Researchers can use them to examine differences in the timing and extent of death among treatment groups and to estimate mortality rates. This time-resolved view helps distinguish rapid effects from delayed effects associated with infection or environmental stress.
Differences in mortality over time can provide evidence about pathogen virulence, meaning the severity of disease caused by an infectious agent, and about how infection progresses in the host. A treatment that produces earlier or greater mortality may indicate a stronger harmful effect. Comparing these patterns among microbial strains helps connect survival outcomes with disease mechanisms.
Insect survival outcomes provide a measurable readout for evaluating innate immune responses and interventions intended to protect the host. When mortality differs between infected insects with and without an experimental treatment, the result can indicate whether the intervention is associated with improved survival. This approach links host defense or treatment effects to a practical infection-related outcome.
A basic workflow includes exposing insects to a defined treatment or infectious agent, maintaining controlled conditions, and recording deaths at regular intervals. These practices make the timing and frequency of observations consistent across groups. The resulting records support calculation of mortality rates and construction of survival curves, allowing outcomes to be compared more reliably.
Standardization reduces differences caused by the experimental setup and makes mortality outcomes more interpretable. With consistent monitoring and controlled conditions, researchers can compare microbial strains, host genotypes, and treatments using the same general framework. Such comparisons help identify whether observed changes in survival are associated with the biological factor being tested rather than inconsistent measurement.
The method is useful when researchers need an outcome for assessing whether an experimental antimicrobial strategy protects infected insects. Mortality measurements can show whether treated groups experience a different survival pattern from untreated or differently treated groups. In immunology and infection research, these results support evaluation of potential interventions while also providing context about pathogen effects and host defense.
