Insect Pest Project

Stable Fly Colony

tjchapman · August 19, 2022 ·

What We Do

The stable fly, Stomoxys calcitrans, is a species of fly in the family Muscidae.  Stable flies are blood feeding insects which use their long mouthparts to pierce the skin of their host and take a blood meal.  They are a serious pest of livestock, particularly cattle and horses.  These flies can cause discomfort to animals while feeding and are known to be vectors of disease.

The Kaufman Laboratory maintains six separate colonies of stable flies.  These vary in original collection location and insecticide resistance status.  All six colonies were established in Florida and were shipped to Texas A&M University in 2020 shortly after Dr. Kaufman’s arrival as the head of the Entomology Department.  These flies have been maintained in lab for generations, most for well over a decade.  There is also an ongoing effort to establish a local colony of Texas stable flies.

Our stable flies need daily care, which requires a thorough knowledge of their developmental stages, food and oviposition preferences.  The colonies are managed by our Ph.D. student Lauren Beebe, and are also maintained by our research assistant Isaac Perez, research worker Travis Anderson, and undergraduates, Megan Bindseil, Audrey Redning, Kierra Kennedy, Fayth Rojas and Macy Strain.

Burrow-Dwelling Soft Tick Project

About the Project

The Search for ticks in burrows of wild animals in Texas

Background

Soft ticks (Family: Argasidae) are vectors of relapsing fever Borrelia in the United States, and potential vectors of African Swine Fever virus, a pathogen that could have a devastating effect on the U.S. swine industry if introduced to the U.S. mainland. One of the current projects undertaken by the Kaufman lab aims to improve our knowledge of the host use and ecology of soft ticks in south Texas.

To this end, CO2-baited sticky traps are deployed in animal burrows, culverts, and other cracks, crevasses, and sheltered areas that may provide refuge for soft ticks. Collected tick samples are subjected to blood-meal analysis and pathogen screening to determine what host species they have fed upon and if they are associated with pathogens that may be of concern for human and animal health.

This research will help to improve our knowledge of the range of soft tick species present in south Texas and the ecological relationships between soft ticks and their hosts. This will aid efforts to identify and mitigate tick-borne disease risks to both humans and domestic animals in south Texas while providing valuable information on the relationships between these ticks, native and exotic wildlife, and livestock.

Insect Vector Project

isaac.perez · June 2, 2022 ·

A STUDY FOCUSED ON MONITORING THE SPREAD OF PATHOGENS, AND EXAMINING ANTIMICROBIAL RESISTANCE GENES THROUGH THE SCREENING OF VECTOR INSECTS ON Livestock

Project Overview

An insect study that focuses on the biological and mechanical transmission of foodborne illnesses, and their associated pathogens.

Enteric pathogens are the leading causes of foodborne illnesses.
Specifically the taxa of Salmonella, Escherichia, and Shigella are in question for this project. We aim to monitor these pathogens
through various insects including, House Fly (Musca domestica),
Blow Fly species such as Cochliomyia macellaria, Lucilia sericata, and
Lesser mealworms (Albitobius diaperinus).

The objective is to determine the role of different insect vectors in
harboring and transmitting foodborne pathogens and antimicrobial resistance genes on poultry farms. The results will inform the development and application of improved vector monitoring to control the spread of pathogens from livestock farms.

Target Species for This Project

Dissections

Perhaps one of the most important steps of this project is dissecting intact alimentary canals.
