چکیده
Sonic pest devices are tools that emit sound in the attempt to repel, deter, or kill unwanted animals such as insects, rodents, birds and large mammals. These devices, depending on the target species, cover a wide range of the acoustic spectrum from below what humans perceive (infrasonic) to above our hearing range (ultrasonic). Infrasonic is characterized as sound below 20Hz, whereas ultrasonic sound is defined as sound above 18,000 Hz. Ultrasonic devices are typically marketed to target arthropod (including spiders, scorpions and insect pests) and mammal pests, while devices targeting birds operate within our normal hearing range (i.e. electronic devices playing back distress calls, racket bombs, and propane cannons).

Mammal Repellents: Options and Considerations for Development
Repellents include chemical substances, visual displays, and sonic and ultrasonic deterrent systems. The use of electric shock also can be considered as a repellent category. Each of these categories is discussed, together with their respective utilities, constraints on their usefulness, and possibilities for future development. Economic considerations that may impede or expedite the developmen...
متن کاملComparisons of antifeedancy and spatial repellency of three natural product repellents against horn flies, Haematobia irritans (Diptera: Muscidae).
BACKGROUND Horn flies are among the most important biting fly pests of cattle in the United States. Horn fly management is largely dependent upon pesticides, which ultimately leads to the rapid development of insecticide resistance. Alternative control strategies, including repellents, have shown promising results in reducing fly biting. In the present study, we examined the efficacy and longev...
متن کاملReview of anthraquinone applications for pest management and agricultural crop protection.
We have reviewed published anthraquinone applications for international pest management and agricultural crop protection from 1943 to 2016. Anthraquinone (AQ) is commonly found in dyes, pigments and many plants and organisms. Avian repellent research with AQ began in the 1940s. In the context of pest management, AQ is currently used as a chemical repellent, perch deterrent, insecticide and feed...
متن کاملNonlethal Repellents: the Development of Cost-effective, Practical Solutions to Agricultural and Industrial Problems
Repellents substances and devices cause pest species to avoid otherwise attractive or palatable materials. For birds, repellents can be visual, auditory, pyrotechnic, tactile, chemosensory, physiologic, or physical. Here, we consider chemical agents only. Few substances are registered with the U.S. Environmental Protection Agency (EPA), and thus legally available for use. This lack of available...
متن کاملChemical Signals and Repellency: Problems and Prognosis
The chemical senses (olfaction, gustation, and chemical irritation or pain) were likely the first to evolve. Their functions are among the most basic-to attract and to repel. Attracting compounds often signal food or sex; repelling compounds presumably signal danger. Among the chemical senses, only olfaction appears to have several functional roles, two of which are modulation of social behavio...
