Abstract/Contents:"The feasibility of disrupting sexual communication in oriental beetle, Exomala orientalis (Waterhouse) with a microencapsulated sprayable formulation of (Z)- and (E)-7-tetradecen-2-one, the major and minor pheromone components, respectively, was evaluated in blueberries and ornamental nurseries during 1998 and 1999 seasons in southern New Jersey. In 1998, pheromone-baited traps captured significantly fewer male beetles in blueberries, treated with a 9:1 blend of (Z)- and (E)-7-tetradecen-2-one at 100 g (AI)/ha of the major component, or in nurseries treated with (_Z)-7-tetra decen-2-one alond at the same rate, compared with trap captures in untreated control plots. The percentage of reduction in trap captures (disruption index)in plots treated with the b;en in blueberried was comparable to reductions in trap captures in nurseries(97 versus 92%)treated with the major component alone. During 1999, pheromone trap captures in blueberry and nursery plots treated with a 93:7 blend of (Z)- and (E)-7-tetradecen-2-one at 37.5 g (AI)/ha of the major component were on an average 92 and 82% lower compared with the trap catures in untreated control plots, respectively. Significantly fewer tethered virgin female oriental beetles were found in copula/contact with males in treated blueberry fields relative to those deployed in untreated control plots. These results suggest that communication disruption is a promising strategy to manage oriental beetle populations in blueberries and ornamental nurseries. This is the first study to document the feasibility of disrupting sexual communication in a soil-dwelling coleopteran with applications of sex pheromone components to the soil."
