Abstract

The ability of Macrolophus pygmaeus to induce systemic resistance in susceptible and Mi1.2 resistant tomato against Meloidogyne spp. was evaluated in 200cm3 pot experiments. The susceptible cv. Roma and the resistant cv. Caramba were exposed to 15 M. pygmaeus nymphs per plant in mesh bags for 48 h and then were inoculated with 200 stage juveniles (J2) of M. incognita or 600 J2 of a mixed community of M. arenaria, M. hapla, and M. javanica. Tomato plants were maintained in a growth chamber during 40 days. Then the number of egg masses and eggs per plant were determined. In addition, the preference of the insect was evaluated confronting nematode-infected vs. non-infected plants in a Y-tube olfactometer and in insect cages, where 10 females were released into each cage containing resistant or susceptible tomato plants. After 1, 2, 4, 24, 48 and 72 h, the number of M. pygmaeus was counted as well as the offspring after 14 days. The infectivity and reproduction of M. incognita were reduced by 37% and 53%, respectively, in susceptible tomato plants inoculated with M. pygmaeus. Inoculation with the nematode community resulted in a 52% reduction in infectivity and a 37% reduction in reproduction. However, no effect was observed in the Mi1.2 resistant tomato plants, regardless of the nematode inoculum. The preference and the offspring of M. pygmaeus was not negatively affected by the nematode infection or the tomato cultivar. In conclusion, pre-induction of tomato plants with M. pygmaeus reduces RKN infectivity and reproduction in susceptible but not in Mi1.2 resistant tomato.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Scientific Reports due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2025, it was in position 25/135, thus managing to position itself as a Q1 (Primer Cuartil), in the category Multidisciplinary Sciences.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-12-14:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 7.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 7 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 8.
  • The number of mentions in news outlets: 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: http://hdl.handle.net/20.500.12327/3808
