♦ Planar observatory nests

Hello fellow termite enthusiast! Let me introduce you to the planar observatory nests, insipired by methodology of scientists M. Lüscher (1949) and Chouvenc et. al (2011). This nests are good option for primitive termites of single-site nesting ecological group.

 

Dimensions: Nest of my dimensions can be made in two rectangular dimensions- 16x20cm or 20x25cm. 1mm gap between nest part and outworld is perfect for moisturing with needle, sufficient for air circulation but still too tight for escaping termites. Closing slice can be made of glass/plastic/wood (155x20mm slice with some cloth/cotton for sealing) or with anything else, it´s everybody´s free choice.

Bottom ,,walls“ are thick 3-4mm, what I find as optimal dimension for bigger species. Those walls  limit the height of arena/nest chambers and whole space at all and can be made of any different (thus termite-durable) material. I find glass as optimal solution. For sticking bottom and walls together, I asked for transparent aquaristic silicone. 

Bottom glass plate have to be 160x200mm, while top glass can be made in one piece 160x200mm,
OR in two pieces 75x200mm (75mm wide plate have close the nest part everytime)
OR in 4 slices – 1x 75x160mm, 2x 45x160mm and 1x 40x160mm. Longer edges have to be fined just a bit (to prevent cutting youreself), as they need to fit together perfectly (that will prevent drafts during manipulation and escapes).

Benefits: Glass plates/slices can hold the glass by using paper binder clips. By using several slices of glass instead of one single plate, you can change wood and material in the arena easily and stress your termite less. You can also cover bottom and the top with a blank of red transparent (plastic) sheet held by binders. As termites can not register the red spectrum, red foil will make fine dark enviroment for them but you can still observe them 😉

For making this amazing nest I must thank to my good friend, Ladislav from V&S Animals -> www.facebook.com/animalsvs

And typical slavic excuse: sorry from my bad english 😀
