il faut vivre ou réfléchir abeille qu’ils disaient ?

L’enveloppe isolante de la grappe est très efficace, car la chaleur rayonnée est très faible. Elle n’est même pas suffisante pour faire apparaître au plafond d’une ruche une couche d’air plus chaud. A quelques centimètres de la grappe, on relève des températures proches, à quelques degrés près, de celle de l’air extérieur sous abri, que la ruche soit bien isolée ou non. On peut donc affirmer que « la meilleure isolation pour une colonie ce sont des abeilles ».

D’innombrables mesures de température effectuées par de nombreux chercheurs dans différents pays ont permis de constater que pendant la période sans couvain, c’est-à-dire d’octobre à janvier sous nos latitudes, la grappe ne « chauffe» pas la ruche. Par suite de la diversité des gîtes naturels et de leur volume très variable, un tel comportement serait d’ailleurs aberrant.

La grappe est tout à fait capable de se défendre elle-même contre le froid. Aux Etats-Unis, FARRAR a hiverné avec succès des colonies dans des ruches aux parois entièrement grillagées. Par rapport aux colonies logées en ruches normales, la température à l’intérieur de la grappe en janvier a été la même. Pour toutes les colonies, il, a mesuré, par des températures extérieures inférieures à 0°, une température d’environ 33° dans le nid à couvain. Il a pu constater l’importance de la protection contre le vent qui peut faire périr les colonies sans abri en quelques jours, par suite du dérangement qu’il provoque.

En 1862, Langstroth constatait également qu’une ruche sans plancher peut « hiverner mieux qu’une colonie soigneusement calorifugée, avec entrée réduite ».

Une isolation trop poussée peut se révéler nuisible aux abeilles, car elle transforme la ruche en chambre froide. Par une belle journée d’hiver, le réchauffement de l’air extérieur n’est même pas perçu par la colonie et elle perd ainsi une occasion précieuse d’effectuer un vol de propreté. Des retards de développement pouvant atteindre deux à trois semaines au printemps ont également été constatés par rapport à des colonies logées en ruches à parois simples.

Le froid n’est donc pas aussi dangereux pour les abeilles que des apiculteurs frileux semblent le croire. Il stimule, au contraire, des colonies fortes, saines et bien nourries.

Petit retour sur mes pihp faites avec une plaque de mousse couverte d’une couche de couverture de survie.
J’en ai mis sur une toute petite colo sur 2 cadres, une vieille reine qui ne pond plus beaucoup, que je n’ai pas tuée mais laissée par curiosité, pour voir si une très petite colo pouvait passer l’hiver.
Elle a passé l’hiver, nourrrie, et l’hiver ni froid ni long.
Elle a actuellement une seule face de cadre de couvain, côté nord, contre la pihp.

Elle a actuellement une seule face de cadre de couvain, côté nord, contre la pihp.

La couverture de survie a 2 sens d’utilisation:
protection du froid:le coté doré vers l’extérieur (car il laisse passer les infra rouges du soleil) et l’argenté vers l’intérieur (car il renvoie les infra rouge du corps vers celui-ci
Protection de la chaleur en cas d’insolation: inversion des faces.
Donc pour tes pihp, je suppose que tu n’as pas mis le coté doré vers les abeilles .

[larc]

Tout juste !
J’ai mis le côté argenté vers les abeilles, l’autre côté est collé sur ma plaque de mousse de 40.

Bonjour,
j’ai utilisé la saison dernière des partitions pihp à ma façon, plaque polistyrène 30mm recouverte d’adhesif brillant qui sert à joindre les isolants mince en isolation.
Je n’y ais trouvé que des avantages, mais il faut relativiser car jusque là je n’utilisais pas de partitions du tout.
Donc est-ce les partitions tout court ou les partitions plus ou moins réfléchissantes qui ont été bénéfiques, je ne sais pas!
Mais je vais m’en faire d’autre et généraliser cette saison.
J’ai accompagné l’agrandissement des colonies en cours de saison avec ces partitions et j’ai réduit les colonies en fin de saison avec également.
A ce jour aucune perte de colonie et du pollen à toutes les ruches, rien n’est encore gagné je le sais, mais ça fait plaisir!

Colle à bois.
Le collage est pas parfait, mais sur la surface, ça va impec.
