Attractant-baited traps for the sugar-beet weevil Bothynoderes (Cleonus) punctiventris: Preliminary study of application potential for mass trapping

Area‐wide mass trapping by pheromone‐based attractants for the control of sugar beet weevil (Bothynoderes punctiventris Germar, Coleoptera: Curculionidae)

“…By mass trapping, we reduced the weevil population up to 11.59% of the total estimated population established by the soil surveys in the donor fields in spring in the mass trapping area. This is much lower compared to the results reported by Tomašev et al . The observed differences in the success could be influenced by the field size, SBW population level and the trap density per hectare.…”

“…Mass trapping with pheromone‐baited traps has been successfully attempted in the family of weevils . Of all examples of successful cases of mass trapping, it is important to note the successful control of American palm weevil ( R. palmarum) in oil palms, and sugar cane weevil Metamasius hemipterus L. and American palm weevil ( R. palmarum) in palmito palm .…”

“…Mass trapping is based on the use of an attractant that draws insects to the traps, where they are caught in large numbers. Attractants include food baits, sex pheromones or aggregation pheromones . Mass trapping offers promising perspectives with beetle pests, where aggregation pheromones are frequently found …”

“…The first is to trap a significant percentage of the overwintering weevils by mass trapping the emerging beetles at the overwintering sites (the ‘old’ sugar beet fields), and the second is to try to intercept beetles that emerged elsewhere when they arrive at the sugar beet fields with beet seedlings (‘new’ fields). Tomašev et al . proposed that a density of 30 pheromone traps ha −1 should be used in donor fields in the case of mass trapping on a single field.…”

Comparative efficacy of classical and biorational insecticides on sugar beet weevil, Bothynoderes punctiventris Germar (Coleoptera: Curculionidae)

“…However, the commercial use of products based on the aforementioned organisms has not been reported. The discovery and employment of aggregation attractant for the beet weevil enables development and implementation of new methods for the population abundance monitoring, and also for the control by adult mass trapping as a means of the overall population suppression (Toth et al 2002;Sivčev et al 2006;Tomasev et al 2007;Bažok et al 2013a,b;Drmić et al 2014). However, chemical control is the main control measure (Inđić et al 1998;Vuković et al 2014) and it will probably remain this way in the near future.…”
