Help of the Plastic Frames

 With this fully drawn plastic frames, it is very simply to get normal bees used to small cells, within a few weeks.. This measure of 4.9 mm is necessary that the bees  can defend themselves against the diseases, without the use of chemicals.

Here we describe how the plastic combs are used.


Without the use of fully drawn plastic frames, this process takes years. They can be replaced with new frames within a short time, once the bees have learned to build this size correctly.

Adriano from Italy has found another factory, who also, I think accidentally,  produces
4.9 mm plastic combs.

Atention - Adriano told us that the italian company Rovera, who built the Rovergarden frames,, went bankrupt. Cheap alternative MannLake from USA or Spain


It seems that they are of good quality and are usefull for our work. Adriano commented that several beekeepers there work with them and it works.
One difference is that the cell depth is greater than in the HSC - how the bees deal with is nice to see on Adrianos page at the bottom.


Here a HSC above and a Rovergarden beneath:

 



 



 



Here are the datas of Mann Lake plastic combs from USA
(now alos available in spain):
The Mannlake plastic comb is a more cost-effective alternative to the HSC.
The difference to the HSC is that the cells are not fully developed and that the cell size is slightly over 4.9mm. Erik Österlund from Sweden reports:
Fast and cheap to small cells

depth of cells: 1,9mm - with rombs at the bottom of the cells
Inner measure of a cell: 4,4mm
10 cells measure 49,7mm - so we have a cell size of 4,97mm
side bar width: 34,8mm - should be grinded to 32mm - so bees will accept this cell siye more easily

Matías de Alicante just tried out the MannLake plastic frames and his bees worked the cells perfectly. He put a swarm, which he recently caught from large cell bees, in a box with 5 MannLake frames without brood. These are bees apis mellifera Ibérica (Iberian black bee).
The plastic combs were coated several times with a roller with liquid wax, so that they were better accepted.

Matías reported that he also placed MannLake frames in a strong Buckfast hive. There they also built the small cells quickly and perfectly.
The only drawback is that these MannLake plastic combs have slightly larger cells than we need, 4.97mm and that it will be a little harder for the bees to build later 4.9mm foundation..
An advantage is that the MannLake comb also has the higher density of cells, unlike the HSC, which in fact have rather thick cell walls, but with the exact cell size of 4.9mm.
Important:
side bar width: 34,8mm - should be grinded to 32mm - so bees will accept this cell siye more easily

Consequently, MannLake combs are a cheap alternative for us.
