2024年7月22日 · In Europe, beekeepers have found a novel solution to the marauding wasps: electric harps. As Reasons to Be Cheerful detailed, the invasive species could cause the collapse of almost one-third...

2024年5月23日 · One crucial benefit is the harps’ specificity in targeting Asian hornets. Their metal wires are spaced about two centimeters apart, which is wide enough for a bee to fly through unharmed — but not a hornet. Because of these selective dimensions, the harps offer a means of killing hornets that is better for biodiversity than other methods.

Harp made entirely of stainless steel, used to protect hives against vespa velutina. It must be connected to an electronic source (purchase separately). 60 cm long by 95 cm high. Harp completely built in stainless steel. Lower insulators finished in stainless metal tip. Stainless steel tempered wire and springs.

Among these methods are electric harps, which are physical barriers that electrocute hornets pass through two wires powered by a current generator. Here we evaluated the selectiveness and risk of damage for local entomofauna of the electric harps in a study carried out over three years and four locations in Girona province (NE Catalonia, Spain).

2022年8月18日 · Electric harps, placed perpendicularly to a line of hives, are useful to reduce the predation pressure of V. velutina in honey bee hives. The trapping of hunting workers represents an advantage over other control methods, such as the beehive muzzles or baited traps, 25 , 37 - 39 as it effectively reduces foraging paralysis in a targeted manner ...

2023年9月4日 · Among the most used control methods are the capture traps, which use a sugary attractant to catch the invasive wasps. However, the species-specific selectivity and efficiency of these traps has...

2024年7月23日 · In Europe, beekeepers have found a novel solution to the marauding wasps: electric harps. As Reasons to Be Cheerful detailed, the invasive species could cause the collapse of almost one-third of France's bee colonies each year.

2021年12月15日 · The electric harps showed a high selectiveness, with 82.9% of all insects trapped (3,902 individuals) catalogued as Asian hornets, although this greatly varied over years and locations with...
