Assessment of the Attraction Range of Sex Pheromone Traps to Agriotes (Coleoptera, Elateridae) Male Click Beetles in South-Eastern Europe

Abstract

The attraction range of YATLORf pheromone traps to adults of four species of Agriotes (A. brevis, A. sordidus, A. litigiosus, and A. ustulatus) was studied to provide additional information about the most harmful Agriotes species in Europe. Male click beetles were marked and released at different distances from a pheromone trap. The recapture rate was calculated and analyzed using analysis of variance. The recapture rate was significantly affected by distance, species, and wind direction. The recapture rate decreased as distance increased. The majority of beetles were caught from short distances (up to 10 m) within the first five days. A. brevis, a mainly crawling species, showed the lowest recapture rate. The wind direction affected the recovery rate, with a significantly lower number of beetles moving downwind from the release points. Maximum sampling ranges and effective sampling areas were calculated. The obtained estimations were low (53 to 86 m and 509 to 2602 m2, respectively) for all the considered Agriotes species, suggesting that they were unsuitable for use as mass trapping instruments to disrupt mating. However, it seems possible to use the traps not only as monitoring tools, but also as attract-and-kill strategies for most beetle populations.

The Effect of Lure Position and Vegetation on the Performance of YATLORf Traps in the Monitoring of Click Beetles (Agriotes spp., Coleoptera: Elateridae)

“…Dense vegetation reduced Yf trap potential for catching Agriotes sordidus ( Table 5 ). The range of trap attractiveness is short (<10 m) [ 19 , 20 , 21 ], but most of the Agriotes beetles generally have a strong attitude for flight. Dense vegetation interferes with flight, as well as with the likelihood of a beetle entering the range of attractiveness, thus probably causing an overall reduction in beetle catches.…”

Plant protection consequences in Hungary of the withdrawal of systemic active substances from sugar beet seed treatment

“…Tenebrionidaesuch as Opatrum sabulosum L. and Omophlus proteus Kirschlarvae, cause damage by chewing the underground organs, may result in wilting and subsequent death especially in drought (Sigareva et al, 2019). Elateridae larvae cause the death of young plants by masticating their immediate underground parts, such as Agriotes sputator L., Agriotes lineatus L., Agriotes obscurus L. and Agriotes ustulatus Schaller (Furlan et al, 2021). Asproparthenis punctiventris Germar, Chromoderus fasciatus Müller Asproparthenis affinis Schrank, Otiorhychus ligustici L. and Psallidium maxillosum Fabricius pose a significant threat to sugar beet production both as larvae and adults.…”

“…In [32], the range of attraction of pheromone traps to agriotes lineatus and agriotes obscurus was assessed. In [33], the authors assessed the attraction range of sex pheromone traps to agriotes male click beetles in South-Eastern Europe. In [34], the authors addressed the space of pheromone plume and its relationship with the effective attraction radius in applied models; for further references, please also see [35][36][37][38].…”
