Morphological variation and reproductive incompatibility of three coconutmiteassociated populations of predatory mites identified as Neoseiulus paspalivorus ( Acari: Phytoseiidae) por Sourassou, N.F., Hanna, R., Zannou, I., Moraes, G. de, Negloh, K., Sabelis, M.W.

“…However, laboratory studies recently conducted have shown large differences in feeding behaviors and biological characteristics among individuals collected from three geographic origins: Brazil (South America), Benin and Ghana (West Africa). As morphologically similar specimens do not necessarily belong to the same species, we evaluated under laboratory conditions, reproductive compatibility between the specimens from three geographic locations to ascertain their conspecificity. …”
