Summary The invasive yellow‐legged hornet was first discovered in Europe, in south‐western France, in 2004. It has since spread very rapidly and has caused significant mortality among honeybees and native entomofauna. It also poses a risk to humans because its sting provokes allergic reactions. The objectives of this study were the following: (i) to disentangle the roles played by human‐mediated dispersal and self‐mediated dispersal in the species' rapid range expansion and (ii) to estimate the intensity of control measures in France and determine what needs to be done to slow the hornet's spread and dramatically reduce its population densities. A mathematical model was developed to describe the hornet's potential spread. This model included parameters describing the population growth rate, carrying capacity, self‐mediated dispersal, human‐mediated dispersal and the efficacy of control measures (i.e. the destruction of detected nests). Model parameters were estimated using 2004–2009 occurrence data for France and the model was then validated using 2013 occurrence data. Several scenarios were tested: human‐mediated dispersal was present or absent and control intensity varied. Then, the species' spread in coming years was simulated (from 2013 to 2020). Despite some uncertainty on the value of the parameters, this model is relatively robust. Human‐mediated dispersal may not be necessarily responsible for the hornet's rapid range expansion; the species could spread rapidly on its own. It is likely that to date, an average of 30–40% of detected nests have been destroyed each year. Increasing the percentage of destroyed nests from 30 to 60% could reduce the species' spread by 17% and its nest density by 29%. If 95% of nests are destroyed, the species' spread and nest density could decline by 43% and 53%, respectively. Synthesis and applications. The mathematical model developed in this study shows that human‐mediated dispersal of the invasive yellow‐legged hornet may not be the only factor explaining the hornet's rapid range expansion and that controlling this invasive pest is still possible. Therefore, there is an urgent need to reduce self‐mediated dispersal and to intensify and improve control measures to diminish the species' impact and prevent its further spread. Control measures could combine the mechanical removal and destruction of individuals or infested materials with biological control techniques.

“…In addition, a high number of non-target animals are commonly captured in baited traps. Several evidences indicate that this low selectiveness of the method has important impacts on the entomofauna threatening native populations of insects (Dauphin and Thomas 2009;Haxaire and Villemant 2010;Monceau et al 2012Monceau et al , 2014Goldarazena et al 2015;Monceau and Thiéry 2017). Together, high recolonization rates and the low selectiveness of baited traps make trapping campaigns ineffective in terms of balance between the benefits to control the invasive population and the environmental costs (Monceau and Thiéry 2017).…”

Performance of baited traps used as control tools for the invasive hornet Vespa velutina and their impact on non-target insects

The efficiency and selectiveness of baited traps to control the invasive hornet Vespa velutina is often questioned. Comparative assessments are needed to improve control plans and reduce the impact on honeybees and entomofauna. Our aims were to study the performance of traps and baits, to identify environmental conditions that affect capture rates and to identify the groups of insects affected by trapping. During spring in 2016, three types of trap and baits in a full factorial design were tested. Vespa velutina accounted for less than 1% of all captures, reflecting the low selectiveness of the method. The trap design and its location are decisive aspects to determine the capture rates of V. velutina queens. All trap-bait combinations captured a very high quantity of dipterans, native hymenopterans, and lepidopterans. High capture rates of insect groups which are not common prey of V. velutina reflect that the method constitutes an additional threat on native insects. apiculture / Apis mellifera / invasive species / pest management tools / yellow-legged hornet

“…Their simple and rudimentary manufacture consists in cutting the upper third of a plastic mineral bottle, which is turned over and pressed into the lower part: this constitutes a creel in the bottom of which one will deposit a mixture of berry syrup, beer and white wine which is supposed to repel bees. The disadvantage of this kind of trap is its significant lack of selectivity with respect to the yellow-legged hornet which represents <1% of the average catch (Goldarazena et al, 2015).…”

Recently, the environmental economist J.M. Salles (Salles, ) declared that “the Asian hornet was likely to be the most threatening invader insect in France.” Thirteen years after the accidental introduction in France, the Asian hornet (Vespa velutina nigrithorax) has invaded most west European countries. Little has been done to date to limit its progression and its economic, ecological and social impact. Although it is illusory to try to eradicate this species, it is known that a targeted control would limit its threatening trend. Current V. velutina control in France is mainly based on (i) high scale volunteer trapping by citizens and (ii) volunteer spotting of the nest. Evaluation of trapping strategies developed so far to control V. velutina expansion has highlighted their failure and has demonstrated the need to optimize nest detection techniques and to investigate on new control strategies. This review describes most of the means aimed to control predation and expansion of V. velutina, whether they have been scientifically assessed or only tested on field with decent success. Published prospective control methods and biological control techniques are also presented.
