Attraction of Lygus rugulipennis and Adelphocoris lineolatus to synthetic floral odour compounds in field experiments in Hungary

Abstract

Field experiments were carried out to ascertain whether synthetic floral odour compounds were attractive for two pest bug species. The European tarnished plant bug (Lygus rugulipennis Poppius) has been reported to damage various crops (e.g. strawberry, sugarbeet, alfalfa, cucumber), and the alfalfa plant bug (Adelphocoris lineolatus (Goeze)) is considered as a pest of alfalfa and Bt-cotton. In our field tests, traps baited with phenylacetaldehyde caught significantly more L. rugulipennis than unbaited traps. In addition, A. lineolatus was also attracted to phenylacetaldehyde-baited traps. When testing other, EAG active compounds, (E)-cinnamaldehyde attracted A. lineolatus as well. This compound was also attractive for L. rugulipennis, however, to a lesser extent than phenylacetaldehyde. When the two compounds were presented in combination, no synergistic or inhibitory effect was detected in either species. By attracting both sexes of both species, these new attractants may prove to be useful and provide the basis for further development of new lures for agricultural use.

Development of a female attractant for the click beetle pest Agriotes brevis

“…Blend 1 comprised two compounds showing activity in both the M. sativa and L. italicum headspace extracts, plus two, from M. sativa only, that elicited the strongest EAG responses in this study. There are cases in the literature when compounds selected on the basis of their EAG performance proved to have field activity and led to an improved attractant for the given species . Blends 2 and 3 comprised blend 1 plus all other active compounds from L. italicum and M. sativa extracts respectively.…”

Design and deployment of semiochemical traps for capturing Anthonomus rubi Herbst (Coleoptera: Curculionidae) and Lygus rugulipennis Poppius (Hetereoptera: Miridae) in soft fruit crops

“…However, phenylacetaldehyde and/or (E)-cinnamaldehyde (Koczor et al, 2012) could be added to the sex pheromone to increase catches of female ETB. An alternative method to the drowning solution, which needs to be emptied and topped up on a monthly basis, would make the trap easier to maintain.…”

“…In addition, some plant volatiles such as phenylacetaldehyde have been identified as attractants for female ETB (Frati et al, 2009;Fountain et al, 2010;Koczor et al, 2012).…”

Fumigant Activity of 6 Selected Essential Oil Compounds and Combined Effect of Methyl Salicylate AndTrans-Cinnamaldehyde AgainstCulex pipiens pallens

“…For example, the addition of phenylacetaldehyde (a general floral odor compound) to traps significantly increased catch of Lygus rugulipennis Poppius and Adelphocoris lineolatus (Goeze) (Hemiptera: Miridae) compared with unbaited traps (Koczor et al 2012). For Holotrichia oblita (Faldermann) (Coleoptera: Melolonthidae), a pest of castor bean (Ricinus communis L.; Malpighiales: Euphorbiaceae), the leaf volatiles dibutyl phthalate and cinnamaldehyde were highly attractive, suggesting potential for use as lures (Li et al 2013).…”

“…Many authors have studied the toxicity and antifeedant activity of plant volatiles in pests (Huang & Ho 1998;Hernández-Lambraño et al 2014;Wang et al 2015). Most effective environmentally friendly antifeedants extracted from plants can be applied in the field against pests (Koczor et al 2012). For instance, fruit and seed extracts from Cabralea canjerana Mart.…”
