A method for RNA interference (RNAi) by injection of dsRNA into unfed ticks is described. RNAi is the most widely used gene-silencing technique in ticks where the use of other methods of genetic manipulation has been limited.

The collection of infected tick hemolymph, salivary glands, and saliva is important to study how tick-borne pathogens cause disease. In this protocol we demonstrate how to collect hemolymph and salivary glands from feeding Ixodes scapularis nymphs. We also demonstrate saliva collection from female I. scapularis adults.

Lyme disease research studies often require generation of ticks infected with the pathogen Borrelia burgdorferi, a process that typically takes several weeks. Here we demonstrate a microinjection-based tick infection procedure that can be accomplished within hours. We also demonstrate an immunofluorescence method for in situ localization of B. burgdorferi within ticks.

Lyme disease is the most commonly-reported vector-borne disease in North America. The causative agent, Borrelia burgdorferi is a spirochete bacterium transmitted by Ixodid ticks. Transmission and detection of infection in animal models is optimized by the use of tick feeding, which we describe here.

Here, we present a protocol to collect saliva, haemolymph, salivary glands, and midgut, following the dissection of an individual fed tick, to study tissue-specific localization of tick-borne pathogens to advance understanding of vector competence and pathogen-microbiome interactions.
FAQs
The destination of the injected material helps determine which tick processes researchers can examine. Delivering a defined substance into a selected compartment allows investigators to connect the experimental exposure with tick physiology, immune responses, pathogen survival, or transmission-related outcomes. This compartment-specific approach supports more focused interpretation than treating the tick as a uniform biological system.
The material chosen should reflect the biological process under investigation. Pathogens can support studies of infection and vector competence, nucleic acids can be used to manipulate tick gene expression, and experimental compounds can probe physiological or immune functions. Comparing these material types helps researchers distinguish effects caused by infection, gene regulation, or chemical intervention.
Standardized conditions reduce differences between experimental groups that are unrelated to the biological question. When researchers control how defined materials are introduced, they can more reliably compare immune responses, pathogen survival, and transmission-related outcomes. Reproducibility is especially important when assessing how tick defenses influence microbes or when evaluating possible disease-control strategies.
A controlled procedure begins by selecting the material and the tick body compartment relevant to the study. Researchers then use a fine needle or glass capillary to penetrate the cuticle and deliver the defined material. Maintaining consistent injection conditions across specimens enables subsequent assessment of physiology, gene expression, immune responses, infection, or transmission-related effects.
Researchers use the technique when they need to examine whether ticks can support infection and contribute to pathogen transmission. Introducing a defined pathogen under controlled conditions creates an experimental starting point for assessing pathogen survival within the tick and its relationship to tick biology. These studies help clarify how vector-associated processes influence infection and transmission.
The method provides a way to manipulate tick biology while observing interactions between ticks and microbes. Investigators can examine how immune defenses affect pathogen survival, alter gene expression to study relevant physiological responses, and compare controlled exposures across experiments. The resulting information can strengthen understanding of tick-borne disease mechanisms and inform research on disease control.
