Abstract

The salicylic acid analog BTH (benzo-(1,2,3)-thiadiazole-7-carbothioic-acid S-methyl ester) induces systemic acquired resistance by promoting plant resistance against numerous plant pathogens and some insect pests. The objective of the research was to evaluate the activation of plant defenses with BTH on melon (Cucumis melo L., Cucurbitaceae) and its effects on the herbivore Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) and on the aphid predator Chrysoperla carnea (Stephens, 1836) (Neuroptera: Chrysopidae). Under laboratory conditions, plants were sprayed with BTH (50 g/ha) zero (B0), four (B4), and seven (B7) days prior exposure to insects. B0 treatment resulted in 100% mortality of aphid nymphs and disrupted adult feeding behavior (recorded by electrical-penetration-graphs technique), by prolonging the time to reach the phloem, requiring more probes to first salivation and reducing ingestion activities. There were no effects on feeding behavior of A. gossypii fed on B4 plants but on its life history because fewer nymphs were born, intrinsic rate of natural growth decreased, and mortality increased. There were no effects on biological parameters of aphids reared on B7 plants. Prey consumption by C. carnea larvae when predated A. gossypii fed on BTH-treated plants was not different among treatments. Therefore, BTH enhances the suppression of A. gossypii in the short term, without negative effects on the predatory larva C. carnea, which makes this plant strengthener a useful tool to be considered in integrated pest management programs.

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 2026-04-27:

  • 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: 24.
  • 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: 24 (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: 1.
  • The number of mentions on the social network X (formerly Twitter): 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:

Project objectives

La aportación persigue los siguientes objetivos: evaluar la activación de las defensas del melón mediante el análogo del ácido salicílico BTH; analizar los efectos de BTH sobre el herbívoro Aphis gossypii en diferentes tiempos de aplicación (0, 4 y 7 días antes de la exposición); determinar el impacto de BTH en el comportamiento alimentario y parámetros biológicos de A. gossypii; caracterizar la mortalidad y tasa de crecimiento intrínseco de las poblaciones de pulgones tras el tratamiento; y evaluar la influencia de BTH en el consumo de presas por el depredador Chrysoperla carnea para valorar su compatibilidad en programas de manejo integrado de plagas.

Most relevant results

Los resultados más relevantes del estudio indican que el tratamiento con BTH a dosis de 50 g/ha aplicado en plantas de melón afecta significativamente a Aphis gossypii y su depredador Chrysoperla carnea. Primero, el tratamiento B0 (aplicado el mismo día de la exposición) provocó una mortalidad del 100% en ninfas de pulgón y alteró el comportamiento alimentario de adultos, aumentando el tiempo para alcanzar el floema y reduciendo la ingesta. Segundo, el tratamiento B4 no modificó el comportamiento alimentario, pero disminuyó la tasa intrínseca de crecimiento y aumentó la mortalidad de pulgones. Tercero, el tratamiento B7 no mostró efectos sobre parámetros biológicos de A. gossypii. Finalmente, el consumo de presas por larvas de C. carnea no varió entre tratamientos.
