Data Sheet Ref:- T602\LEKy\GA92_95A

Date of Issue of Data:-
(Thought to be 1995 for the leaflet with 1992 being product inception date.)

Ingredient: ACRINATHRINE, 1.2 - 1.7 mg in one strip

(I have an older copy of the leaflet that gives 1.0 - 1.5 mg per strip. I think the change occurred about 1994/95, but I am not certain.)

Properties and Effectiveness
Strip (carrier)
(is made) from the gabon veneer (it) contains (a polymer) mixture with bound acarinathrine, which is released (by) diffusion in small quantities to the strip surface. It is spread in the colony by contact with the strip and by the mutual contact (between) bees.
Mites from the brood cells are afflicted after the emerging of bees at the contact with contaminated bees. The medicament is determined for the protection of winter bees in the late summer and in autumn in colonies with high intensity of varroasis. GABON PA-92 is not used in the time of the reduced activities of bees (bees in winter cluster). GABON PA-92 controls also bee lice.
(Braula assumed)

The bee colony is dismantled and two strips are hung into slightly enlarged bee ways between brood combs symmetrically into the brood body centre (for instance into the 2nd and the 5th bee way). Only at very strong colonies which possess the brood in two boxes we hang one or two strips more. Strips are hung on hooklets. One hooklet as a sample is enclosed to each package of strips. The strip is to hang freely between combs. It must not be disturbed.

Strips are left in the colony for two periods of sealed brood, i.e. 24 to 30 days. After this period strips are taken out. Strips may be used repeatedly without losing the effectiveness.
(I am not sure that this is what the original translator meant to say... Please exercise caution, it maybe should read do not re-use strips!)

Term of Cure
(Season of Treatment)
Strips are used after the last honey extraction.
(After supers are removed.)

Safety Rules
(nitrile rubber) gloved hands handle the strips. If skin is affected, it is washed with water and soap. Do not take meals, drinks, do not smoke at the work. Store in a locked dry room separately from food and feed. Strips are to be protected from fire, light, frost.

If the application methods are kept, no danger of impairment of honey, bee stores and beeswax.
Only on Vet prescription!

Packing: A packet contains 50 strips and 1 hooklet (sample).
Czech strip hanging hooklet designed by Vladimir Vesely
The 'hooklet' mentioned is intended to be copied and used to hang all strips. It is also used for other purposes in Czech bee medication. In use the strip is threaded onto the dip and then lowered between two frames.

Further details Emailed after an enquiry about what the active ingredient was...
Dear Dave,
Acrinathrin is a substance from the group of pyrythrans, which is
similar to pyrethroids.
Toxicological data for vertebrates are very good: LD 50 acute oral for
rats is higher than 5000 mg/kg, ADI for men is 0,02 mg/kg.
Acrinathrin shows high acaricide property in very low concentrations.
The dose of acrinathrin in one strip is less than 2 mg.
Acrinathrin is an active substance of GABON PA 92 strips, which are
produced in our Institute.
Best regards,
