Yet, little is famous on potato odour pros getting T. solanivora location away from companion and you will/or oviposition site. Interestingly, Bosa et al. (2011) stated that virgin sexy indonesian girls females was basically significantly more keen on rose odour than simply to help you odours of one’s whole bush or even to tubers, in an olfactometer take to. Given that attraction to help you plant life one of virgin women moths is generally related that have place regarding feeding web sites and not off oviposition web sites (Cunningham mais aussi al. 2006; Saveer mais aussi al. 2012), the new part off potato rose odour from the machine finding strategy regarding T. solanivora has to be searched.

Potato gives off erratic compounds that are types certain while some one imply the high quality as well as the phenological phase of one’s plant life (Bolter mais aussi al. 1997; Agelopoulos et al. 2000; Karlsson mais aussi al. 2009, 2013). Every potato bush structures, potato dried leaves, tubers, and vegetation generate ingredients, many of which was antennal effective so you’re able to T. solanivora (Karlsson mais aussi al. 2009). Semi-occupation trapping assays showed that the new compound methyl phenylacetate (MPA) released off potato herbs in the higher number and potato tubers from inside the brief volume attracts T. solanivora. Yet not, MPA in combination with a leading concentration of six-methyl-5-hepten-2-one (sulcatone), a material found in tubers, reduces the appeal (Bosa mais aussi al. 2011).

The aim of the current investigation would be to define the cues utilized by T. solanivora to track down its server. We hypothesize you to, because tuber development and flowering peak exist at the same time from inside the potato herbs, potato rose odour could publication women to get an enthusiastic oviposition website. To evaluate so it theory, conduct assays was basically held to see or watch impulse off T. solanivora so you’re able to man-made blends, understood regarding and you will representing more potato plant formations. The fresh mating standing determine regarding the behavior try looked at also given that requirement for personal substances regarding extremely attractive merge.

Fresh bugs

A lab colony of one’s Guatemalan potato moth T. solanivora, via the new Colombian Business to possess Agricultural Lookup (Corpoica), is based. The newest nest are interbred frequently that have nuts Colombian moths and try reared for the potato tubers in containment establishment on SLU, Sweden. Pests was in fact maintained during the 60 ± 10% RH and you will 18 ± dos °C significantly less than an effective photoperiod off L16:8D. People having electrophysical try out was indeed stored in Plexiglas cages (33 ? 33 ? 33 cm 3 ) and you will fed that have ten% honey solution, while grownups on olfactometer assays was basically fed just with water twenty-four h just before tests.


Synthetic compounds (Desk 1 ) were tested into the a dose–effect work through electroantennographic tape technique (EAG) more than four commands away from magnitude: 0.01, 0.step 1, 1 and you can ten ?g ?l ?step 1 . The latest ingredients had been toned down within the hexane (99.9% Lichrosolve, Merck KGaA, Darmstadt, Germany). Personality and quantification regarding potato, Solanum tuberosum, var. Little princess, odour had been predominantly done in a past analysis (Karlsson mais aussi al. 2009). Those people analyses, along with joint energy chromatography and you can electroantennal recognition (GC-EAD), found 17 ingredients during the potato headspace which might be antennal energetic to own T. solanivora. Even more collection from the exact same bush varieties and you can diversity, examined having GC-EAD towards the people, revealed that benzaldehyde, 1-octen-3-ol, 3-octanone, and you may 2-phenylethanol, also are antennal effective. Ergo, artificial brands of these four compounds was basically here tested together with the in the past known substances. Girls bugs, aged dos–3-time article introduction and you will several–24-h blog post mating were used towards assay. To the first 30 min pursuing the onset of the fresh new photophase, any copulating sets have been chosen and you can lightly relocated to an alternative situation. Males and females was indeed separated into more cages after a single complete mating skills. Antennae was basically slash on the bottom and you may mounted with electroconductive gel (Cefar, Lund, Sweden) during the an effective forked antenna manager (Syntech Products and you can Lookup, Kirchzarten, Germany) and you can consistently exposed to charcoal-blocked and you may humidified heavens (1.5 l min ?step 1 ). Brand new odour stimulus had been prepared by implementing 10 ?l of each material at for each serving into the bits of filter out paper (0.5 ? 2 cm), registered in the a Pasteur pipette. A smoking equipment (Syntech stimuli controller CS-55) introduced a great 0.5-s long sky smoke that have a beat of 1 ml sek ?step one through the Pasteur pipette and you will into humidified airstream passage over the antenna. Per antenna is confronted with several stimuli, in a single amount peak, that have been demonstrated in arbitrary order, to eliminate sphericity. The latest stimuli series constantly started and you may finished having blank, hexane, and people pheromone part (E)-3-dodecenyl acetate, [(E)-3-12:Ac) (Pherobank, Wageningen, Holland >99.6%] (Nesbitt mais aussi al. 1985) as the resource, as this material got shown reproducible EAG answers. For each stimuli is actually showed about step one minute after the earlier in the day stimuli to stop adaptation of your own antenna. Maximum amplitude of your EAG answers try filed and you may analysed toward EAG-adjusted software (Syntech, EAGPro ver. 2.0).
