Attraction of Euwallacea nr. fornicatus (Coleoptera: Curculionidae: Scolytinae) to lures containing quercivorol
Keywords:
avocado, ambrosia beetle, attractant, quercivorolAbstract
Euwallacea nr. fornicatus (Eichhoff) (Coleoptera: Curculionidae: Scolytinae) is an exotic ambrosia beetle that vectors fungal Fusarium spp. to avocados. Two field trials testing potential attractants to trap Euwallacea spp. were conducted in south Florida. Quercivorol + Ultra High Release Ethanol (URH) was the most powerful attractant for E. nr. fornicatus in the 2 field trials. In Florida, the populations of E. nr. fornicatus are small. The attractiveness of quercivorol lures to other Euwallacea spp. should be tested in conditions where population levels are greater as in California and Israel.
Sumario
Euwallacea nr. fornicatus (Eichhoff) (Coleoptera: Curculionidae: Scolytinae) es un escarabajo ambrosial exótico que transmite hongos del genero Fusarium spp. a árboles de aguacate. Se realizaron dos experimentos de campo para probar el potencial de atrayentes para Euwallacea spp. en el sur de Florida. Quercivorol + Etanol en alta taza de liberación (URH) atrajo más E. nr. fornicatus en los dos experimentos. En Florida las poblaciones de E. nr. fornicatus son bajas. La atracción de quercivorol a otras especies de Euwallacea spp. debe ser probada en lugares donde las poblaciones de estos insectos son más altas como California e Israel.
