Abstract

Simple Summary The European pepper moth is an important pest of many crops; however, some countries, such as Brazil, do not have insecticides registered for combating this pest. In particular, the egg stage of the biological cycle of this moth is the most difficult life stage to control. In this sense, biological control agents, including egg parasitoids and entomopathogenic fungi, can be an alternative to pesticides. In this study, laboratory tests were conducted to evaluate the susceptibility of two species of egg parasitoids (Trichogrammatidae family) to entomopathogenic fungal strains (including two commercial bioinsecticides). These fungal strains were applied on eggs of the European pepper moth before and after parasitism by the parasitoids. Overall, the entomopathogens reduced the parasitism rate, adult emergence, and longevity of adult parasitoids by less than 30%. The results obtained constitute the first step in designing effective pest control strategies. Future research should investigate the sub-lethal effects of the fungal strains on the parasitoids in the field. The European pepper moth,Duponchelia fovealis(Lepidoptera: Crambidae), is a key pest in strawberry production. Entomopathogenic fungi (EF) and parasitoids of the Trichogrammatidae family are effective biological control agents of this pest with the potential to be used jointly for improved efficacy. This study aims to evaluate the susceptibility ofTrichogramma atopoviriliaandTrichogramma pretiosumto twoBeauveria bassianastrains (B2 and B3) and two commercial bioinsecticides (Bovemax(R)and Methamax(R)) by applying them toD. fovealiseggs in pre- and post-parasitism periods. Pre-parasitism application of B2 and B3 did not affect the percentage ofD. fovealiseggs parasitized by eitherTrichogrammaspecies, except in the case ofT. atopoviriliawhen eggs were sprayed with B3 at 1.5 x 10(5)conidia mL(-1)(16.7% less than the control). In contrast, eggs sprayed with 1.5 x 10(8)conidia mL(-1)of the commercial bioinsecticides were not parasitized by anyTrichogrammaspecies. Overall, the EF tested reduced the parasitism rate, adult emergence, and longevity ofTrichogrammaadults by less than 30% in all cases. The adverse effects of theB. bassianastrains and commercial products on the biological traits of bothTrichogrammaspecies were minimal, meaning that these agents can be used jointly inD. fovealiscontrol strategies.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Insects 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, 2020, it was in position 18/102, thus managing to position itself as a Q1 (Primer Cuartil), in the category Entomology.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.59. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 13, 2025)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 1.49 (source consulted: FECYT Mar 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2026-04-02, the following number of citations:

  • WoS: 17
  • Scopus: 17
  • Europe PMC: 4

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 2026-04-02:

  • 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: 32.
  • 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: 31 (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:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
