Semiochemical based integrated livestock pest control.

The role of arthropods as livestock pests has been well established. Besides their biting habits causing nuisance in animals; they are important vectors for transmission of economically important livestock diseases worldwide. Various pests and vector control managemental programs that also make use of chemicals have variable success rates. Consequently, insecticide/acaricide resistance has been reported against most of the commonly used chemicals along with increased concern for environment and demand for clean and green, residue-free animal products. This calls for an urgent need to develop novel, alternate, effective strategies/technologies. This lays the foundation for the use of semiochemicals as alternatives along with other biological control agents. Current knowledge on semiochemical use in livestock is refined and limited; however, it has been widely exploited in the agricultural sector to control plant and food crop pests, surveillance, and monitoring. Semiochemicals have an added advantage of being natural and safe; however, knowledge of extraction and quantification by using assays needs to be explicit. Expertise is required in behavioral and electrophysiological studies of arthropods and their interactions with the host and environment targeting specific semiochemicals for promising results. A thorough prior understanding on aspects such as mechanism of action, the stimulus for the release, the effecter/target species, response produced, application methods, dose and concentration is required to develop any successful pest/vector control program. The current review provides essential and frontline information on semiochemicals and their potential applications in the livestock sector along with future challenges and interventions.
