“…Several compounds attractive to corn rootworm beetles and present in squash blossoms, namely indole, /3-ionone, 2-phenyl-1-ethanol, and phenylacetaldehyde (Andersen and Metcalf, 1986;Andersen, 1987;Metcalf, 1987, 1988;Metcalf and Lampman, 1989), also occur in corn (Thompson et al, 1974;Flath et al, 1978;Buttery et al, 1978Buttery et al, , 1980Cantelo and Jacobson, 1979). Considerable additional information exists on volatiles of corn plants (Thompson et al, 1974;Flath et al, 1978;Buttery et al, 1978Buttery et al, , 1980Cantelo and Jacobson, 1979;Buttery and Ling, 1984;Turlings et al, 1993;Takabayashi et al, 1995), but few of these compounds have been tested for attractiveness to corn rootworm beetles.…”

Synthetic corn volatiles and selected analogs were tested in commercial corn fields for attractiveness to feral northern (NCR,Diabrotica barberi) and western corn rootworm beetles (WCR,D. virgifera virgifera). Two new attractants, geranylacetone and α-terpineol, were identified among corn terpenes and compared at four stages in crop development with the phenylpropanoid standards cinnamyl alcohol and 4-methoxy-cinnamaldehyde, with each component at 30 mg/trap. Dose-response relationships (0.1-100 mg/trap) and efficacy of two-component blends (30 mg/component) were also examined. More beetles were captured on traps baited with (+)- than (-)-α-terpineol, but the difference was statistically significant only for WCR. Captures with geranylacetone or (+)-α-terpineol were directly proportional to the logarithm of the attractant dose. WCR females were attracted to as little as 0.1 mg of either compound. WCR males required ≥ 1.0 mg of (+)-α-terpineol and were not attracted to geranylacetone at any dose. NCR required ≥0.3 mg of either attractant and showed less marked response differences between the sexes than did WCR. Geranylacetone and cinnamyl alcohol were equally effective attractants, whereas (+)-α-terpineol was significantly less attractive to WCR but more attractive to NCR than was 4-methoxycinnamaldehyde. Corn terpenes and phenylpropanoid standards produced similar seasonal response patterns in that captures tended to rise in each case as the season progressed, except during silking when no compound was attractive. Mixing corn terpenes or phenylpropanoid standards synergized responses of WCR females, but (+)-α-terpineol suppressed attraction of NCR females to geranylacetone.

“…The attraction of the bean and pea leaf weevil (Blight et al 1984), boll weevil (Dickens 1989), Mediterranean fruit fly, and smaller European elm bark beetle (Dickens et al 1990) to synthetic formulations of their male-produced, sex-and aggregation-pheromones was found to be enhanced by the presence of a particular group of HPVs, the "green-leaf volatiles" (GLVs). GLVs are found ubiquitously throughout the plant kingdom and have been defined as certain simple, aliphatic six-carbon primary alcohols, aldehydes and acetates (Visser et al 1979;Buttery 1981;Tressel et al 1981;Schreier 1984). The GLVs are metabolites of the oxidative degradation of fatty acids and are often produced when enzymes are liberated due to plant tissue damage.…”

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

et al. 1993

Summary. The capture of adult male moths in female sex pheromone traps of two key agricultural pests, the corn earworm (Helicoverpa zea) and the codling moth (Cydia pomonella), is enhanced or synergized by a certain group of host-plant volatiles, the "green-leaf volatiles" (GLVs). Since female adults of both species call and release their sex pheromones while perched upon the leaves of their host-plants, the volatile constituents from the leaves of a number of host-plants were compared. Sex pheromone traps containing one of the prominent leaf volatiles of certain H. zea hosts, (Z)-3-hexenyl acetate, not only significantly increased the capture of H. zea males but were preferred over traps baited only with sex pheromone. Similarly, traps baited with synthetic sex pheromome of C. pomonella plus a blend of GLVs captured significantly more males than traps baited only with sex pheromone. Since male moths are not captured in traps baited only with these GLVs, it appears that these GLVs act as pheromone synergists which increase or enhance the attraction or arrestment of male moths in pheromone traps.

“…Various complex blends of volatile plant compounds leave the plant surface and are transported away by wind. In the atmosphere around maize leaf surfaces more than 90 components have been detected (Buttery & Ling, 1984). Although not measured in the current study, it is known that higher plant densities reduce wind speed in agroecosystems (Bottenberg & Irwin, 1992).…”

Studies were conducted in South Africa to assess the potential role of a habitat management strategy developed for the control of cereal stemborers in control of Astylus beetle. This strategy involves intercropping maize with a stemborer moth-repellent fodder plant (Desmodium) ('push'), with a stemborer moth-attractant host plant (Napier grass) ('pull'), planted as a perimeter/trap crop around the plot ('push-pull' system). Treatments were habitat managed plots, comprising of 'push-pull' and 'pull' plots, and maize monocrop plots (control). A combination of choice tests and field trials were employed to evaluate any impact of this system on Astylus beetle colonization of maize fields. Results showed Significant reductions in beetle populations in habitat managed plots (>60 %). Similarly, there was a significant reduction in beetle capture (>50%) in Desmodium-baited yellow water traps in two-choice tests, although the total number of beetles captured was generally low «50%). In addition, Desmodium caused a reduction of 11-15% in beetle captures in the multiple-choice tests. Habitat management thus shows potential for use in Astlyus beetle management in maize in the affected areas, largely through the barrier effects of Napier grass.
