Los \u00faltimos estudios para investigar por qu\u00e9 las abejas se est\u00e1n muriendo implican el seguimiento de estos peque\u00f1os insectos, pero \u00bfc\u00f3mo se rastrea a una abeja?<\/span><\/strong><\/span><\/p>\n

El n\u00famero de abejas ha estado cayendo dram\u00e1ticamente<\/span><\/strong> y los cient\u00edficos est\u00e1n intentando entender por qu\u00e9.<\/span><\/span><\/p>\n

Las abejas de todo tipo -hay cientos de ellos- desempe\u00f1an un papel crucial en la vida del campo y <\/span><\/strong>una tercera parte de lo que comemos depende de la polinizaci\u00f3n que ellas llevan a cabo. Estudiar el comportamiento de estos complejos insectos es clave para descubrir qu\u00e9 est\u00e1 pasando, pero tambi\u00e9n es un gran desaf\u00edo.<\/span><\/span><\/p>\n

<\/span><\/p>\n

Una abeja puede visitar varios miles de flores en un d\u00eda y volar varios kil\u00f3metros, \u00bfc\u00f3mo seguirle la pista?<\/strong><\/span><\/span><\/p>\n

Los cient\u00edficos est\u00e1n utilizando la tecnolog\u00eda del radar arm\u00f3nico<\/strong>. Un transmisor de radar emite una se\u00f1al para que la reciba que una diminuta antena pegada en el t\u00f3rax de una abeja de miel. Un peque\u00f1o diodo en el centro de la antena cambia la longitud de onda para que pueda ser detectada y seguida.<\/span><\/span><\/p>\n

La nueva se\u00f1al es \u00fanica<\/span><\/strong>. No hay ninguna otra fuente en el medio ambiente, as\u00ed que los cient\u00edficos saben que la est\u00e1 emitiendo la abeja marcada. Una estaci\u00f3n de rastreo de radar port\u00e1til se utiliza para transmitir la se\u00f1al y reunir la informaci\u00f3n enviada de vuelta.<\/span><\/span><\/p>\n

Se ha demostrado que la exposici\u00f3n a los pesticidas neonicotinoides afecta la capacidad de las abejas para navegar<\/span><\/strong><\/em>. En una prueba realizada por el profesor Randolf Mendel, dos abejas fueron capturadas y equipadas con transmisores de radio. Una de las abejas fue expuesta a neonicotinoide. Cuando ambas fueron liberadas, a cierta distancia del sitio de captura, la abeja expuesta fue incapaz de encontrar su camino de regreso a la colmena<\/span><\/em> <\/span><\/span><\/p>\n

The latest studies to investigate why the bees are dying involve the monitoring of these small insects, but how crawled to a bee?<\/span><\/span><\/p>\n

<\/span><\/p>\n

The <\/span>number<\/span> of bees has been falling dramatically, and scientists are trying to understand why.<\/span><\/span><\/p>\n

<\/span><\/p>\n

………………<\/span><\/span><\/p>\n

<\/span><\/p>\n

The bees of all kinds – there are hundreds of them – they play a crucial role in the life of the field and a third of what we eat depends on pollination that they carry out. Study the behaviour of these complex insects is key to discovering what’s going on, but it is also a great challenge.<\/span><\/span><\/p>\n

<\/span><\/p>\n

A bee can visit thousands of flowers in a day and fly several kilometers, how do keep you track?<\/span><\/span><\/p>\n

<\/span><\/p>\n

………………<\/span><\/span><\/p>\n

<\/span><\/p>\n

Scientists are using harmonic radar technology. A radar transmitter emits a signal so that it is received that a tiny antenna attached to the thorax of a honey bee. A small diode in the center of the antenna changes wavelength so that it can be detected and followed.<\/span><\/span><\/p>\n

<\/span><\/p>\n

The new signal is unique. There is no other source on the environment, so scientists know that marked bee is issuing it. A portable radar tracking station is used to transmit the signal and <\/span>gather<\/span> the information sent back<\/span><\/span><\/p>\n

<\/span><\/p>\n

…………….<\/span><\/span><\/p>\n

<\/span><\/p>\n

The signal being sent from tagged insect looks like a point in movement similar to those seen on the ships radar screen.<\/span><\/span><\/p>\n

<\/span><\/p>\n

Accurately depicts how far is bee and in which direction flies. A computer program reconstructs the trajectory of flight.<\/span><\/span><\/p>\n

<\/span><\/p>\n

\u00abThis <\/span>can be<\/span> superimposed on the maps of the area to show accurately where the insect flew and the characteristics of the landscape of the area\u00bb, he tells the BBC Jason Chapman, an entomologist from the center of agricultural research Rothamsted Research in England<\/span><\/span><\/p>\n

It has been shown that exposure to pesticides neonicotinoids affects the ability of bees to navigate. In a test carried out by Professor Randolf Mendel, two bees were captured and fitted with <\/span>radio<\/span> transmitters. One of the bees was exposed to neonicotinoide. When both were released, some distance from the site of capture, exposed bee was unable to find his way back to the hive<\/span><\/span><\/p>\n
