Attraction ofCacoecimorpha pronubana male moths to synthetic sex pheromone blends in the wind tunnel

Abstract

Attraction ofCacoecimorpha pronubana male moths to blends of four sex pheromone components was studied in the wind tunnel.Z11-14∶Ac alone did not elicit upwind flight, admixture of 10%Z11-14∶OH or more led to successful attraction of males to the source. Attractivity of these binary blends was further enhanced by addition ofE11-14∶Ac orZ9-14∶Ac; the optimum was a blend ofZ11-14∶Ac,Z11-14∶OH,E11-14∶Ac, andZ9-14∶Ac at the proportion of 100∶30∶3∶3. In ternary and quaternary blends, the effect ofZ11-14∶OH andE11-14∶Ac was strongest at 30% and 3%, respectively. By contrast,Z9-14∶Ac increased behavioral responses over a wide range.

Host-plant green-leaf volatiles synergize the synthetic sex pheromones of the corn earworm and codling moth (Lepidoptera)

“…Presently, the chief cost of commercial pheromone products is the pheromone itself. The use of a greater number of pheromonal components in a lure formulation system will increase its efficacy for many species (Baker & Card6 1979;Linnet al 1984Linnet al , 1986Linnet al , 1987Witzgall 1990), but will also dramatically increase the manufacturer's costs. However, the cost of GLVs is a fraction (between <0.1 and 5%) of the commercial cost of a typical pheromone component.…”

New Sex Pheromone Blend for the Lightbrown Apple Moth, Epiphyas postvittana

“…For example, in the European grapevine moth, Lobesia botrana, the two minor components, (E,Z)-7,9-dodecadienol and (Z)-9-dodecenyl acetate, elicited peak attraction at 5% and 1% amounts (of the major component), respectively (El-Sayed et al, 1999). In tortricid moths, such as Grapholita molesta (Baker et al, 1981;Linn and Roelofs, 1983), Adoxophyes orana (Guerin et al, 1986), Cacoecimorpha pronubana (Witzgall, 1990), and Spilonota ocellana (Witzgall et al, 1991), males responded to a wide range of ratios of the minor components.…”

Electroantennogram, wind tunnel and field responses of male Mediterranean corn borer, Sesamia nonagrioides, to several blends of its sex pheromone components

“…Thus, all four compounds are essential to maximise the overall mating response. S. nonagrioides behaves similarly to other species with multicomponent pheromone blends: for example, the noctuids Trichoplusia ni Hübner (Linn et al, 1984), Heliothis virescens F. (Teal et al, 1986), and Chrysodeixis chalcites Esper (Dunkelblum & Mazor, 1993), the tortricids Cydia molesta Busck (Linn & Roelofs, 1983), Argyrotaenia velutinana Walker (Linn & Roelofs, 1989), Choristoneura occidentalis Freeman (Sweeney et al, 1990), and Cacoecimorpha pronubana Hübner (Witzgall, 1990) or the pyralid Chrysoteuchia topiaria Zeller (Kamm et al, 1989).…”
