Optimization of a Phenylacetaldehyde-Based Attractant for Common Green Lacewings (Chrysoperla carnea s.l.)

Abstract

In field trapping tests, the catch of Chrysoperla carnea sensu lato (Neuroptera: Chrysopidae) increased when acetic acid was added to lures with phenylacetaldehyde. The addition of methyl salicylate to the binary mixture of phenylacetaldehyde plus acetic acid increased catches even further. The ternary blend proved to be more attractive than beta-caryophyllene, 2-phenylethanol, or 3-methyl eugenol (compounds previously described as attractants for chrysopids) on their own, and no influence on catches was recorded when these compounds were added as fourth components to the ternary blend. There were minimal changes in activity when (E)-cinnamaldehyde or methyl anthranylate (both evoking large responses from female or male antennae of C. carnea in this study) were added, although both compounds showed significant attraction on their own when compared to unbaited traps. In subtractive field bioassays with the ternary mixture, it appeared that the presence of either phenylacetaldehyde or methyl salicylate was important, whereas acetic acid was less so in the ternary mixture. The ternary blend attracted both female and male lacewings at sites in southern, central, and northern Europe. Possible applications of a synthetic attractant for lacewings are discussed.

Attraction responses of ladybird beetle Hippodamia variegata (Goeze, 1777) (Coleoptera: Coccinellidae) to single and binary mixture of synthetic herbivore-induced plant volatiles in laboratory tests

“…Similarly, Jones et al (2010) reported that the attractiveness of iridodial (a maleproduced aggregation pheromone) increased when MeSA was added, doubling the number of lacewings captured in traps in apple orchards. Toth et al (2009) Additionally, the binary combination (MeSA+E(2)H) were not attractive for the predator insect, though we obtained significant results concerning insect attraction to MeSA with Be or F. Our results are also in accordance with some results about the differences in olfactory responses in other predator and parasitoid species to various blends of HIPVs (Simpson et al, 2011;Van Wijk et al, 2011;Maeda et al, 2015). It seems likely that ecological differences may be the cause of such variations in the olfactory responses of different coccinellid species.…”

First Transcriptome and Digital Gene Expression Analysis in Neuroptera with an Emphasis on Chemoreception Genes in Chrysopa pallens (Rambur)

“…Mass production and release of C. pallens in fields is economically unfeasible compared with recruitment of existing individuals in the environment. Based on the feeding habits of adult lacewings, several plant-derived compounds were suggested as attractants [19]–[22]. Recently, individual aphid sex pheromone compounds (enantiomers of nepetalactol and nepetalactone) were shown to attract predatory males of Chrysopa spp.…”
