Attractants for the Green June Beetle (Coleoptera: Scarabaeidae)

Abstract

The purpose of this study was to develop and evaluate lures for adult green June beetles, Cotinis nitida (L.) (Coleoptera: Scarabaeidae), for future use in a mass trapping program. Volatile organic compounds collected from headspace of green June beetles feeding on fermenting ripe apple (Malus spp.), the natural lure that elicits feeding aggregations, were identified and confirmed by gas chromatography and mass spectrometry. Yellow funnel traps baited with 91% isopropanol or the five component blend were equally effective in eliciting aggregation behavior and often more attractive to green June beetles than the natural lure. In 2008, three trap lines adjacent and parallel to the perimeter of two vineyards, each with 12 Xpando yellow funnel traps baited with either 91% isopropanol or the five component blend, differed in catch of green June beetles across sample dates, and sample date by bait interaction but there were no differences among these two baits. A season total of 324,007 green June beetle were captured by these 36 baited traps. A brief review is included of fermentation volatiles attractive to insects. We conclude with the potential cost to use mass trapping against adult green June beetles.

The ecology of insect–yeast relationships and its relevance to human industry

“…Many other nitidulid species, such as Carpophilus humeralis and Aethina tumida, similarly show a strong preference for yeast-derived volatiles in baits [59,60]. Volatiles from fermentation are also known to promote feeding aggregations in members of various plantfeeding beetle groups such as Chrysomelidae, Scarabaeidae and Scolytinae (Curculionidae) [61][62][63]. A wide range of wood-associated Coleoptera also responds to yeast-generated signals.…”

Attraction of the Invasive Hornet, Vespa velutina nigrithorax, by using Bacillus sp. BV‐1 Cultures

“…These studies suggest that 3-methyl-1-butanol can play a role in pest management programs. Other minor volatiles detected in the BV-1 cultures, such as 2-methyl-1-propanol, 3-methylbutanoic acid, 2-phenyethnol, and fatty acid esters, are also insect chemical attractants and pheromones (Hossain et al, 2008;Johnson et al, 2009;Tóth et al, 2002;Okumu et al, 2010;Trhlin and Rajchard, 2011). These indicate that the volatile metabolites produced by BV-1 cultures relate to insect attraction.…”

An assessment of factors leading to the decline of Beclardia macrostachya (orchidaceae) population in Mauritius

“…Talose (a rare sugar) and arabinose were reported to be a component of the nectar of Brassica napa [34]. Benzyl alcohol/(Benzene methanol,4-hydroxy) is known to be insect attractant and reported to be major components of floral [35][36][37][38][39][40]. Of the other aromatic compounds detected in Beclardia macrostachya, methoxybenzyl alcohol and methoxy methyl phenol are also reported to be a component of floral scents in orchids [37].…”
