Special Issue Information

Dear Colleagues,

Historically, research on the ecology of insect species in the context of biological control has remained largely in demand, particularly when it is focused on insects of economic importance. The biological control of pests has been widely practiced since ancient times; nevertheless, more studies highlighting its importance are being conducted today. To this end, we are launching a Special Issue on pest ecology and biological control in oil and row crops. The main required article types are articles (original research manuscripts) and reviews (concise and precise updates on the latest progress made in each area of research).

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Hyadaphis foeniculi is a significant phytosanitary issue in fennel (Foeniculum vulgare) cultivation, necessitating rational management strategies, such as biological control using entomopathogenic fungi and natural predators. This research aimed to assess the virulence parameters of the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae, isolated or in mixture, in the mortality of H. foeniculi, and investigate the compatibility of these fungi with the predator Euborellia annulipes, analyzing the functional response when preying-on-aphids. The experiment was conducted under laboratory conditions. The lethal concentrations (LC50 and LC90), the median lethal time (LT50), and the percentage of survival of H. foeniculi nymphs subjected to topical application of the fungi were evaluated. No significant difference existed between the lethal concentrations and LT50 of the fungi alone or combined, with LC50 estimated at 1.17 × 106 conidia of B. bassiana per milliliter of water suspension and 1.20 × 106 conidia of M. anisopliae per milliliter of water suspension, when isolated. When in mixture, we observed LC50 for the mixture of fungi M. anisopliae and B. bassiana estimated at 3.06 × 103 viable conidia of B. bassiana, and 1.17 × 103 viable conidia of M. anisopliae per mL of distilled water. Therefore, the mixture of fungi showed remarkable promise, resulting in a high aphid mortality rate. Adult females of E. annulipes were used to evaluate the compatibility of the fungi with this predator and were exposed to the fungi to assess its functional response to nymphs of fennel aphid. The fungi had no significant effect on the functional response parameters of the females exposed to the treatments. Thus, the two bioagents (predator and fungi) proved compatible and promising for fennel aphid biological control programs. Full article
