Phenylacetaldehyde: A chemical attractant for common green lacewings (Chrysoperla carnea s.l., Neuroptera: Chrysopidae)

Abstract

Abstract. At five sites in Hungary and Italy, traps baited with phenylacetaldehyde caught significantly higher numbers (10 to 100 times more) of green lacewings than unbaited traps, which demonstrates that this compound is an attractant. Traps with three bait dispensers usually caught more than those with one dispenser, but the difference was significant only at two out of five test sites. There was no difference in the numbers caught by sticky delta and funnel traps baited with phenylacetaldehyde. However, funnel traps could be adapted to catch living green lacewings. The vast majority of the specimens belonged to the Chrysoperla carnea species complex. Ch. carnea sensu lato dominated the catches at all sites. At some sites 3-11% of the insects caught were Ch. lucasina Lacroix. Phenylacetaldehyde-baited traps were attractive to both sexes, but generally more females were caught than males. Funnel traps baited with three dispensers of phenylacetaldehyde caught green lacewing adults throughout the season in Hungary.

Smells good, feels good: oviposition of Chrysoperla carnea-complex lacewings can be concentrated locally in the field with a combination of appropriate olfactory and tactile stimuli

“…However, the adults are not predatory and feed on pollen, nectar and honeydew (Bozsik 1992;Canard 2001). In accordance with the feeding habits of adults, plant-derived compounds have been tested as attractants (Flint et al 1979;Zhu et al 1999;Tóth et al 2006). A ternary bait comprising synthetic floral compounds was also developed, which showed higher attractiveness to C. carnea-complex adults than previously published attractants (Tóth et al 2009).…”

Furthermore, it was found that females laid their eggs on baited traps (Tóth et al 2009;Jaastad et al 2010) and in the vicinity of the baits (Koczor et al 2015).…”
