Male and Female Noctuid Moths Attracted to Synthetic Lures in Europe

Abstract

In field tests in Europe, traps baited with a blend of isoamyl alcohol, acetic acid, and isobutanol (compounds previously found attractive to a number of noctuids in North America) caught the following noctuid moths: Agrotis segetum Schiff., Agrotis crassa Hbn., Agrotis exclamationis L., Amathes (Xestia) c-nigrum L., Apatele rumicis L., Amphipyra pyramidea L., Dipterygia scabriuscula L., Discestra trifolii Hfn., Euxoa aquilina Schiff., Euclidia glyphica L., Mamestra brassicae L., Mamestra oleracea L., Mamestra suasa Schiff., Mythimna albipuncta Den. & Schiff., Mythimna l-album L., Noctua pronuba L., and Trachea atriplicis L. A substantial percentage of the catch of each species of moths was females. The presence of isobutanol in the mixture was important for catching A. rumicis, D. trifolii, and E. glyphica. The addition of 3-methyl-1-pentanol to the ternary mixture did not increase trap captures of any of the moths. Traps baited with the floral attractant phenylacetaldehyde alone caught several species of noctuid moths. However, when phenylacetaldehyde was added to the isoamyl-alcohol ternary blend, no increases in catches of any of the species, relative to the ternary blend or phenyacetaldehyde alone, were observed, with catches of most species being depressed. Comparing the noctuid species attracted to the phenylacetaldehyde- and isoamyl alcohol-based lures showed that phenylacetaldehyde attracted predominantly Plusiinae and Melicleptriinae spp., while isoamyl alcohol-based lures attracted species mostly from the Noctuinae or Hadeninae subfamilies.

An improved female-targeted semiochemical lure for the European corn borer Ostrinia nubilalis Hbn.

“…The chemicals tested were selected based on their occurrence in the scents of maize silk (Hammack, 1996) or of flowers visited by pest moths (Haynes et al, 1991;Heath et al, 1992;Landolt and Smithhisler, 2003;Guédot et al, 2008;Landolt et al, 2014) and their performance in past field tests as moth attractants (Landolt et al, 2001(Landolt et al, , 2006(Landolt et al, , 2011Meagher and Landolt, 2008;Tóth et al, 2010). We evaluated chemicals in combination with PAA and in comparison with PAA.…”

Seasonal response ofNoctua pronubaLinnaeus, 1758 (Lepidoptera: Noctuidae) to traps in Washington State

“…Mean (± SEM) numbers of N. pronuba moths captured in traps baited with acetic acid (AA), 3-methyl-1-butanol (MB), or the combination of acetic acid and 3-methyl-1-butanol AAMB) in traps baited with acetic acid plus 3-methyl-1-butanol (Tóth et al 2010, Landolt et al 2011b, two volatile chemicals that have been isolated from fermented sweet baits attractive to moths (Utrio & Erikkson 1977, El Sayed et al 2005. Results of four experiments reported here demonstrate the attraction of N. pronuba moths to AAMB, further confi rming the original fi nding of Tóth et al (2010). Also, we show a positive interaction of the two chemicals in attracting the moth and the necessity of including both compounds to make an effective lure.…”

“…The moth has also been captured in traps baited with the combination of acetic acid and 3-methyl-1-butanol (AAMB) (Tóth et al 2010, Landolt et al 2011a which are volatile chemicals that have been isolated from fermented sweet baits (Utrio & Erikkson 1977, El Sayed et al 2005.…”

Field evaluation of synthetic kairomonal attractants against major lepidopteran pests of castor

“…Male and female moth attraction to and feeding from blooming plants has been noted for several lepidopteran pest species (Guedot et al, 2008). Floral chemicals or synthetic kairomones have been experimentally demonstrated as attractants for trapping several lepidopteran species (Meagher and Landolt, 2010;Toth ., 2010). In order to identify the synthetic kairomones or floral chemicals that elicit attraction from major lepidopteran pests of castor, a method of screening is required.…”

“…Since lepidopteran moths are highly attracted to the volatile cues present in the floral parts of host plants for both ovipositing and nectar feeding, this could be used as the basis for monitoring or management strategy (Burguiere ., 2001). In the recent years, kairomones, a type of semiochemicals which include the chemical volatiles emitted by plants have been experimentally demonstrated as attractants for trapping of several lepidopterans (Toth ., 2010;Landolt ., 2011). Management by 'lure and kill' using floral chemicals or synthetic kairomonal attractants have been experimentally demonstrated as an effective method to attract lepidopteran pest moth species in agricultural crops (Camelo ., 2007;Gregg ., 2010).…”
