Dear all,
Hope following information may help to control and reject africanized beehives.
Digital photos and computers optimize the techniques to determine bee races.
The use of digital photos and image vectorizing softwares have allowed traditional morphometrical taxonomy identify africanized bees just with a picture of the right forewing of bees.
A photographic image is transformed into vectors able to be related to one another and analyzed in logical form by a statistical softwares in a few minutes.
Tiago Francoy, from USP (Brazil), applied this technique to determine africanized bees and he achieved an effectiveness of more than 99%. He made the comparative works using the Rutner collection as reference and samples from the whole Brazil.
Original work was published in English by Apidologie: Apidologie 39 (2008) 488-494 © INRA/DIB-AGIB/ EDP Sciences, 2008 DOI: 10.1051/apido:2008028
Detailed description of the technique, results and the charts that identify the main commercial bees races were published in Spanish in Espacio Apicola edition No. 89.
best regards
fernando
