The method described here utilizes direct injection of entomopathogenic bacteria into the hemocoel of Manduca sexta insect larvae. M. sexta is a commercially available and well-studied insect. Thus, this method represents a simple approach to analyzing host-bacterial interactions from the perspective of one or both partners.

Here, we detail a simple, fast, and reliable multiparametric flow cytometry- and tumor-on-a-chip-assisted protocol to monitor and characterize the steps constituting the cancer-immunity cycle. Indeed, a thorough understanding of the interplays between cancer and immune cells provides critical insights to outsmart tumors and guide clinical care.
FAQs
Behavioral responses arise from integrating olfactory, gustatory, and mechanosensory information rather than relying on a single cue. Olfactory signals contribute to host-plant interactions, gustatory input helps relate behavior to feeding, and mechanosensory information supports responses involving movement and contact. Studying this integration shows how sensory evidence is combined to produce adaptive actions.
Neural circuits and hormonal signaling coordinate behavioral responses by linking sensory information with actions appropriate to context. In Manduca sexta, this coordination is relevant to feeding, locomotion, mating, and defensive behavior. Examining both forms of signaling helps researchers relate observable responses to nervous-system function rather than treating behavior as an isolated output.
Manduca sexta research can connect sensory cues with decision-making and learning because the same behavioral framework includes feeding, locomotion, mating, and defense. Investigators can ask how an animal selects an action when environmental information changes, then relate that response to sensory processing. This makes behavior a bridge between observable actions and nervous-system function.
Because anatomy, physiology, and behavior can be examined across developmental stages, researchers can compare how these features are expressed at different points in development. This cross-stage perspective supports analysis of stable behavioral characteristics as well as stage-associated differences. It also helps connect behavioral observations with the changing organization and function of the nervous system.
Researchers can organize a study by pairing observations of behavior with examination of anatomy and physiology, then comparing findings across developmental stages. The species supports this approach because all three levels can be examined in the same model. Such comparisons help connect a visible action, such as feeding or defense, with the biological systems that accompany it.
The species supports questions about how sensory processing becomes behavior, how animals make decisions, and how learning relates to nervous-system function. These questions can be examined through responses associated with feeding, locomotion, mating, or defense. Consequently, Manduca sexta offers a way to study both individual behaviors and broader principles linking neural activity with adaptive action.
Host-plant interactions provide a context for examining how herbivorous insects use environmental information to guide behavior. Olfactory and gustatory cues are especially relevant because they can be considered alongside feeding responses and sensory processing. Studying this relationship connects nervous-system function with an ecologically meaningful problem: how behavior helps an animal respond to its plant environment.
