Alvaro Romero-Research Interest

My research interests and activities are based upon my desire to work at the interface of urban entomology, chemical ecology, toxicology, and animal behavior. The approach I endeavor to take is one that strikes a balance between basic and applied research. My career objectives are to 1) explore research opportunities into insects in the urban environment at an institution fostering collaborative relationships; 2) serve as an educator and mentor to future scientists; and 3) serve as a bridge between the scientific community and minority groups to educate on identification, biology, and effective ways to prevent and reduce the impact of urban pests.

I am particularly interested in basic and applied research on blood feeding insects. Bed bugs have resurged as the most pressing emerging issue in urban entomology reducing quality of life in affected people. The sudden resurgence of bed bugs and the limited knowledge of their biology presents many challenges for the bed bug management today. Thus, my research objectives are designed to provide not only practical information for the pest control industry and its stakeholders, but also to begin to resolve the knowledge vacuum that surrounds this pest.

A second area of interest are kissing bugs. Although few locally-transmitted cases of Chagas disease have been reported in the United States, the disease is considered an emerging public health threat because of the widespread prevalence of T. cruzi among sylvan and domestic animals, the increasing recognition of endemic areas of Chagas disease in some parts of the United States and the seasonal dispersion of adult triatomines (Triatoma sp.) competent for T. cruzi transmission that readily invade houses and feed on humans. In light of changing climates, changing patterns of human movement, and growing socioeconomic inequality in the United States, feeding activity of kissing bugs generally, and T. rubida in particular, represents a serious, hitherto-unrecognized, health risk. My program conduct research to unravel the sensory ecology of host-seeking by important southwestern triatomines and to identify attractant cues that can be used for the development of effective traps for monitoring and controlling triatomines in the United States.

My last active area of research are Turkestan cockroaches. The Turkestan cockroach, Blatta lateralis has become an important invasive urban pest throughout the Southwestern United States. In Arizona and New Mexico, hundreds of Turkestan cockroaches are seen in animal feed mills, around sheep feeders, and places where animal manure accumulates. These cockroaches occasionally invade human environments through holes, cracks, and gaps between doors and floors. Infestations of Turkestan cockroaches in indoor areas can lead to airborne exposure to allergens derived from saliva, feces, and shed exuvia of cockroaches that trigger both asthma and allergies in sensitized people. My laboratory is exploring the use of botanical insecticides as alternatives of traditional insecticides for the control of this cockroach in urban environments. Also, I am interested in the study of sexual behavior and characterization of sexual pheromones of Turkestan cockroaches that can be potentially used in trapping systems.
