Bioacoustics of Haematopinus suis

Remarks: Ferris (1933 , 1951 ) redescribed and illustrated Haematopinus suis , including a complete list of many described subspecies, which he regarded as junior synonyms. Kwak et al. (2019) documented the first record of H. suis in Singapore , located south of Peninsular Malaysia . Considering that Singapore wild boars originated from Peninsular Malaysia in the 21 st century ( Yong et al. 2010 , Kwak et al. 2020 ), it follows that H. suis was already established in Malaysia , although there are few records of this louse species from this country (see above). Song et al . (2014) found variation in the mitochondrial minichromosome composition between Haematopinus suis and H. asini . Haematopinus suis is known to harbor a multitude of disease-causing pathogens, such as the swine pox and African swine fever viruses ( Doster 1995 ; Sánchez-Cordón et al. 2018 ). Haematopinus suis is known as a vector of Mycoplasma suis , the aetiological agent of porcine infectious anaemia, recognized as medically important due its zoonotic potential, ( Hu et al. 2009 ; Acosta et al . 2019 ). Although hog lice are not known to bite humans, other vectors, such as ticks, may transmit pathogens from pigs to humans ( Wu et al. 2006 ).
