Research Article Widespread infestation of <i>Pyemotes</i> <i>tritici</i> (Acari: Pyemotidae) in colonies of seven species of stored-product insects

Abstract: Pyemotidae mites are ectoparasites of a large number of arthropods, and Pyemotes tritici (Acari: Pyemotidae) is often found parasitizing insects in various habitats, including in the laboratory. Here we report widespread infestation of P. tritici in laboratory colonies of various species of stored-products insects. P. tritici infestations were observed in laboratory colonies (MIPGrains/UFV) of Sitophilus zeamais (Coleoptera: Curculionidae), Alphitobius diaperinus (Coleoptera: Tenebrionidae), Lasioderma serrico… Show more

“…Therefore, this is the first report of the cotton boll weevil being parasitized by P. tritici. Because this mite species is free-living, being commonly found in dried, insect-infested plant products such as hay, straw, and grains (Sousa et al, 2020); we believe that they were introduced into the greenhouse through the substrate incorporated into the soil used for cotton cultivation. In Brazil, infestations by P. tritici of nests of stingless bees, Melipona subnitida, M. asilvae, Tetragonisca angustula and Frieseomelitta varia (Hymenoptera: Meliponina) and of laboratory reared Sitophilus zeamais (Coleoptera: Curculionidae), Alphitobius diaperinus (Coleoptera: Tenebrionidae), Lasioderma serricorne (Coleoptera: Anobiidae), Acanthoscelides obtectus (Coleoptera: Bruchidae), Rhyzopertha dominica (Coleoptera: Bostrichidae), Ephestia sp.…”

“…Males are the first to be born, as adults, immediately copulating with their adult sisters. The newborn females immediately seek new hosts, which once parasitized, become paralyzed by the release of toxins (Sousa et al, 2020). Neurotoxins from a single female are sufficient to paralyze an insect host up to 150,000 times the size of the mite (Mullen and Oconnor, 2019).…”
