Entre los m\u00e9todos para monitorizar la infestaci\u00f3n de varroa en los colmenas, tambi\u00e9n se ha sugerido el uso del di\u00f3xido de carbono. Este m\u00e9todo no letal consiste en anestesiar a las abejas mel\u00edferas con CO2 en un frasco y contar los \u00e1caros expulsados de los insectos. Pero seg\u00fan un estudio reciente realizado en Estados Unidos, la eficacia de este m\u00e9todo es baja, lo que resulta en estimaciones inexactas del nivel de infestaci\u00f3n. Los investigadores concluyeron que los m\u00e9todos m\u00e1s precisos siguen siendo el lavado de las abejas con agua jabonosa o alcohol. En cambio, seg\u00fan otro estudio, el mejor m\u00e9todo para m\u00e9todos no letales es agitar la miel con az\u00facar en polvo.<\/p>\n\n\n\n

This non-lethal method consists in anaesthetising honey bees by CO2 in a jar and counting the mites dislodged from the insects. But according a recent study carried out in the US by the, the efficacy of this method is low, resulting in inaccurate estimates of the infestation level. The researchers concluded that the most accurate methods remain yet washing bees with soapy water or alcohol. Instead, for non-lethal methods, according an other study the best one is the powdered sugar shaking.<\/p>","protected":false},"author":3,"featured_media":4026,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1,6],"tags":[],"class_list":["post-4025","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
