Abstract
A synthetic blend of the aggregation pheromone [(3R,4S, 1'E)-3,4-bis(1 '-butenyl)tetrahydro-2-furanol, linalool, farnesol, and nerolidol] of the spined citrus bug, Biprorulus bibax, and the pentatomid defense ch emical, (E)-2-hexenal, both attracted adult B. bibax to individual tre es in citrus orchards. Lemon trees containing single glass vials with aggregation pheromone or (E)-2-hexenal were colonized by significantly greater numbers of reproductive B. bibax than unbaited trees. There w as no significant difference between the treatments and bug recruitmen t was not improved by using both treatments. B. bibax did not enter cy linder/funnel traps baited with aggregation pheromone but colonized tr ees containing the traps. Orange or lemon trees containing aggregation pheromone on orchard perimeters recruited significantly larger popula tions of emigrating, nonreproductive B. bibax during fall than untreat ed trees. Nonreproductive bugs were not attracted to trees containing (E)-2-hexenal. The potential for using these semiochemicals as managem ent tools for B. bibax is discussed.
