Second link mentioned PI 134417 having 2-Tridecanone in its leaves which can kill parasites, other insects. So figured I would do a small search.
https://www.researchgate.net/publication/7377420_Natural_Products_Repellency_and_Toxicity_of_Wild_Tomato_Leaf_Extracts_to_the_Two-Spotted_Spider_Mite_Tetranychus_urticae_KochEnded up finding this fun link. Seems like there are different chemicals in different accessions. Could try out multiple accessions, wouldn't want insects to adapt too quickly... The link provides even more accessions. Might be able to find related research with these.
Lethality of extracts was mainly associated with the presence of high concentrations of 2-tridecanone; repellency of extracts was mainly associated with the presence of trans-caryophyllene. Leaf extracts of L. hirsutum f. glabratum accessions that contain significant quantities of 2-tridecanone and/or trans-caryophyllene could be useful for managing populations of spider mites, which could reduce reliance on synthetic pesticides. Zingiberene isn't mentioned here very much - it was mentioned in the other studies using LA2329 frequently.
Edit: 2-Tridecanone is mentioned once in the nifa.usda link. The actahort link doesn't contain 2-tridecanone either, could be in the full book though. Trans-caryophyllene isn't mentioned in any of the other links.
The S. habrochaites accession PI 134417 produces intermediate-chain methyl ketones in its trichome secretions. Four MKs (2-tridecanone, 2-undecanone, 2-dodecanone, 2-pentadecanone) and their mixture were screened for repellency and ability to alter fecundity of spider mites. All MKs repelled spider mites. Spray application of crude leaf extracts prepared in ethanol, average number of eggs/female mite dropped from 0.9 to 0.3 24 h after exposure a 68% reduction, suggesting that crude extracts of certain S. habrochaites accessions may possess anti-arthropod activities, and could be useful as an aid in agriculture. - nifa.usda link
Could be that some of these chemicals just weren't identified or named in LA2329 research projects.
Some other accessions that were highly repellant:
PI 134417 (No Known Plant ID) Ecuador
PI 134418 (No Known Plant ID) Ecuador
PI 251304 (LA0407) Ecuador
PI 126449 (26) Peru
Assuming that PI 134417 and PI 134418 were collected from around the same area. Could have different chemical levels? If they have no differences, there probably wouldn't be two accessions. Only one of these is from outside Ecuador.
Managed to find the LA0407 name by searching PI 251304 in the database. Helped me find this fun little PDF
https://nph.onlinelibrary.wiley.com/doi/pdf/10.1111/nph.14130.
It mentions LA1777 and LA0407 introgression lines, all sorts of fun stuff. LA0407 is similar to LA2329, so this some of this research probably still fits in pretty well.
The difference here seems to be that LA0407 is Self Compatible, LA1777 is Self Incompatible.
Talks a good bit about intraspecific crosses being linked to SI, and other things.
Luckily LA2329 crosses well enough with domestics that this research isn't needed for this accession.
