Description
Summary:Pyemotidae mites have been reported as ectoparasites of a large number of arthropods, especially of insects. These mites are frequently found attacking insects in different habitats, including insect rearing. This paper reports the occurrence of Pyemotes sp., ventricosus group, in colonies of Tuta absoluta (Meyerick) (Lepidoptera: Gelechiidae), Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) and Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), in the insect rearing laboratory of ESALQ-USP, in Piracicaba, State of São Paulo, provoking dematitis in those involved with the rearing. This is the first report of a Pyemotes species parasitizing T. absoluta and S. zeamais. Considering the capacity of Pyemotes to cause dermatitis in human beings, demonstrated by other authors, the direct use of the Pyemotes species found in this work for the control of the reported insect species may not be promising.
