“…5). Host-plant volatiles, particularly GLVs, can enhance the response of insects to their pheromone Reddy and Guerrero, 2004). For example, (Z)-3-hexenyl acetate enhanced the response of the diamondback moth, Plutella xyllostella (L.), to its sex pheromone (Reddy and Guerrero, 2000).…”

“…1 mg/day (ChemTica Internacional S.A., San José, Costa Rica). Because green leaf volatiles often synergize with insect pheromones (Reddy and Guerrero, 2004), we also tested the attraction of A. musculus to the GLVs (Z)-3-hexenyl acetate and hexyl acetate alone or in combination with the aggregation pheromone components. Both (Z)-3-hexenyl acetate and hexyl acetate are emitted from blueberry flower buds and flowers and elicit strong antennal responses from A. musculus (Szendrei et al, 2009).…”

Identification and Field Evaluation of Attractants for the Cranberry Weevil, Anthonomus musculus Say

Studies were conducted to develop an attractant for the cranberry weevil, Anthonomus musculus, a pest of blueberry and cranberry flower buds and flowers in the northeastern United States. In previous studies, we showed that cinnamyl alcohol, the most abundant blueberry floral volatile, and the green leaf volatiles (Z)-3-hexenyl acetate and hexyl acetate, emitted from both flowers and flower buds, elicit strong antennal responses from A. musculus. Here, we found that cinnamyl alcohol did not increase capture of A. musculus adults on yellow sticky traps compared with unbaited controls; however, weevils were highly attracted to traps baited with the Anthonomus eugenii Cano aggregation pheromone, indicating that these congeners share common pheromone components. To identify the A. musculus aggregation pheromone, headspace volatiles were collected from adults feeding on blueberry or cranberry flower buds and analyzed by gas chromatographymass spectrometry. Three male-specific compounds were identified: (Z)-2-(3,3-dimethyl-cyclohexylidene) ethanol (Z grandlure II); (Z)-(3,3-dimethylcyclohexylidene) acetaldehyde (grandlure III); and (E)-(3,3-dimethylcyclohexylidene) acetaldehyde (grandlure IV). A fourth component, (E)-3,7-dimethyl-2,6-octadien-1-ol (geraniol), was emitted in similar quantities by males and females. The emission rates of these volatiles were about 2.8, 1.8, 1.3, and 0.9 ng/adult/d, respectively. Field experiments in highbush blueberry (New Jersey) and cranberry (Massachusetts) examined the attraction of A. musculus to traps baited with the male-produced compounds and geraniol presented alone and combined with (Z)-3-hexenyl acetate and hexyl acetate, and to traps baited with the pheromones of A. eugenii and A. grandis. In both states and crops, traps baited with the A. musculus maleproduced compounds attracted the highest number of adults. Addition of the green leaf volatiles did not affect A. musculus attraction to its pheromone but skewed the sex ratio of the captured adults towards females. Although the role of plant volatiles in host-plant location by A. musculus is still unclear, our studies provide the first identification of the primary A. musculus aggregation pheromone components that can be used to monitor this pest in blueberry and cranberry pest management programs.

“…Insects perceive a range of volatile products emitted by plants that serve them as signals in the search for food, oviposition sites and for shelter against desiccation and enemies (Syed and Guerin 2004; Schoonhoven et al 2005). Host plant products can also serve phytophagous insects to locate rendezvous sites for mating (Landolt and Phillips 1997;Reddy and Guerrero 2004) whereby the probability to encounter the opposite sex may be enhanced. In this manner, host plant choice and mate choice are tightly linked.…”

Host plant volatiles serve to increase the response of male European grape berry moths, Eupoecilia ambiguella, to their sex pheromone

2009

The European grape berry moth is an important pest in vineyards. Males respond to the female-produced sex pheromone released from a piezo nebulizer in a dosedependent manner in a wind tunnel: <50% arrive at the source at 5-50 pg/min (underdosed), 80% arrive at 100 pg/ min to 10 ng/min (optimal) and <20% arrive at 100 ng/min (overdosed). Males responding to overdosed pheromone show in Xight arrestment at 80 cm from the source. Host plant chemostimuli for Eupoecilia ambiguella increase the responses of males to underdosed and overdosed pheromone. (Z)-3-hexen-1-ol, (+)-terpinen-4-ol, (E)--caryophyllene and methyl salicylate released with the underdosed pheromone cause a signiWcant increase in male E. ambiguella Xying to the source. Time-event analysis indicates a positive correlation between faster activation and probability of source contact by the responding males. The four host plant compounds added to the overdosed pheromone permitted males to take oV faster and with a higher probability of Xying to the source. This suggests that perception of host plant products with the sex pheromone facilitates male E. ambiguella to locate females on host plants, lending credence to the hypothesis that plant products can signal rendezvous sites suitable for mating.

“…Em outros casos, compostos derivados da planta hospedeira, após um ataque de herbívoro, podem atrair predadores, servindo como um mecanismo de defesa para a planta (REDDY; GUERRERO, 2004). Porém, há casos em que os voláteis de planta podem provocar uma resposta positiva sobre o comportamento dos insetos em resposta a feromônios liberados em associação com a planta hospedeira.…”
