Sample collection

 

 

If you are interested in the study of mites and parasites, we propose you to make for us occasionnal sample collections. We will be happy to receive samples from you environment and will make our best effort to make a microscopic mount and take photos.

If it is possible for us, we can try to help you identifying the family / genera / species of your samples.

Sample collection should be occasional and should preserve Nature and your Environment ! Please pay attention to your local legislation.

Protocol for sample collection

Subjects of interest

It is very important to have samples entire, not destroyed, not smashed, with all pairs of legs if possible, because all details can be important for identification. Moreover, a wrecked subject will not be interesting and the photo will be bad looking and will probably not allow clear identification.

  • Mites already sorted from soil or plant
  • Parasites isolated from their host, preferably not gorged with blood.
  • Mites in phoresy with or without the phoront, if you can identify the phoront (the insect which is covered with mites), it is preferable, as our competences in entomology are limited.
  • Do not collect only one mite ! Several are necessaries, because some of them could be damaged, and for microscopy, it is always prefereable to show several individuals on a slide (show venter and dorsum at least).

How to send

  • The sample should be preferably conserved in alcohol (60-70°). A high degree alcohol will degrade the subject, or the subject will be to fragile and break like glass.
  • The subject could be sent dry for hard mites or insectes rolled in absorbing paper, but this way of conservation is not prefered.
  • The sample should be in small watertight platic tube, like eppendorf for example. Do not forget to tape or tighten correctly the cover lid/cork, to prevent any leakage. Glass tube is prohibited.
  • The sample can be sent in an envelop or a package depending on the size. Make sure that the envelop is correctly sealed.

Required information

A sample collection should always be accompanied with the following data :

  • Geographical location (country, city…),
  • Type of ecosystem (forest soil, plumage of bird, under stones, cave,…),
  • The type of host or phoront for parasites or phoretic mites, with the species if it is known,
  • The date of collection,
  • The name and address of the person who is collecting and / or sending the sample.

Local legislation and endangered species

  • Please respect your local legislation before sending any sample.
  • Please respect sanitary rules before sending any sample particularly with parasites liable to infest other persons or living beings.
  • All endangered species should be respected and not collected. For example, ectoparasites found only on another critically endangered species,is often itself an endangered species. See an example here on IUCN red list with Haematopinus oliveri.

Postmail address

Your sample can be sent to the following address :

mites-and-parasites.org

O. Levoux

9 Grande Rue

35240 MARCILLE-ROBERT

FRANCE

Please make sure that there is no error in the address, otherwise the sample will never arrive !

Do not forget to note also the address of sender on the envelop or the package.

After receiving your sample

  • Be patient ! Obtain a slide of quality is quite difficult, and requires time and patience !
  • We will start a process of clarification of the sample for preparing microscopic mount. The clarification process can be very long depending on the subject.
  • If you are only interested in a first identification, let us know, we will try to send you information as soon as a result will be obtain. The consulattion of an expert is sometimes required.
  • We will keep trace of the collecting person. If you agree, we will mention your name as collector of the sample.
  • Once the sample will be mounted and shot, a publication will be done on mites-and-parasites. Do not hesitate to interact with us !

 

Thank you for your help and your interest.

  1. Bonjour Olivier,

    Nous avons dû nous rencontrer une fois à l’occasion d’une AG du Gretia…
    Je me permets de te contacter car dans le cadre de mes activités professionnelles au CPIE Loire Anjou (Beaupréau, 49) je suis amené à faire des inventaires faune-flore et je peux collecter occasionnellement des acariens. Pour l’instant je les conservais en alcool ne sachant pas trop quoi en faire et donc si jamais tu es intéressé pour les récupérer je pourrai te les faire parvenir (il n’y a qu’une 20aine de tubes environ).
    Moi et mes collègues faisons ces récoltes pour la connaissances de la biodiversité de l’Anjou et cela ne rentre pas dans le cadre de projets facturés ou délimités dans le temps. Ainsi nous n’avons aucune exigence sur un retour des déterminations des bêtes ou le délais pour le faire, tu peux ne les regarder que dans 10 ans sans souci ! De même nous n’avons pas besoin d’un retour des échantillons.
    Bien sûr nous serons intéressé le cas échéant par les identifications réalisées pour connaitre ce que nous avons par chez nous en espèces !

    Pour info nous transmettons à JC Beaucournu les quelques puces que nous pouvons récolter (surtout sur animaux domestiques !) et j’ai récemment fait un envoi de tiques à Mme Degeilh sur les conseils de M. Beaucournu.

    Bien cordialement,

    Olivier Durand
