Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Genetics
  • Botany

Francesco Pennacchio focuses on Botany, Acyrthosiphon pisum, Host, Aphid and Parasitoid. His Botany study integrates concerns from other disciplines, such as Apoptosis and Cellular differentiation. Biochemistry and Amino acid is closely connected to Braconidae in his research, which is encompassed under the umbrella topic of Acyrthosiphon pisum.

His Kairomone study, which is part of a larger body of work in Host, is frequently linked to Pore-forming toxin, bridging the gap between disciplines. The concepts of his Aphid study are interwoven with issues in Rhizosphere and Aphididae. Parasitoid is a subfield of Hymenoptera that Francesco Pennacchio explores.

His most cited work include:

  • EVOLUTION OF DEVELOPMENTAL STRATEGIES IN PARASITIC HYMENOPTERA (438 citations)
  • Neonicotinoid clothianidin adversely affects insect immunity and promotes replication of a viral pathogen in honey bees (401 citations)
  • Synergistic parasite-pathogen interactions mediated by host immunity can drive the collapse of honeybee colonies. (279 citations)

What are the main themes of his work throughout his whole career to date?

Francesco Pennacchio mainly investigates Botany, Parasitoid, Aphid, Braconidae and Host. His research integrates issues of Gene and Cell biology in his study of Botany. His research in Parasitoid intersects with topics in Olfactometer and Parasitism.

His Aphid research includes elements of Kairomone, Cornicle, Aphidius ervi, Aphididae and Insect. Francesco Pennacchio has researched Braconidae in several fields, including Lepidoptera genitalia, Biochemistry and Homoptera. His Heliothis virescens research is multidisciplinary, incorporating elements of Endocrinology, Instar, Prothoracic gland and Polydnavirus.

He most often published in these fields:

  • Botany (34.29%)
  • Parasitoid (31.43%)
  • Aphid (25.71%)

What were the highlights of his more recent work (between 2017-2021)?

  • Immune system (13.57%)
  • Microbiology (7.14%)
  • Mite (5.71%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Immune system, Microbiology, Mite, Deformed wing virus and Varroa destructor. His research on Microbiology also deals with topics like

  • Spodoptera littoralis that intertwine with fields like Gene, Gene silencing, Systemin and Cell biology,
  • Plant defense against herbivory which connect with Trichoderma harzianum, WRKY protein domain and Insect. His Mite study combines topics in areas such as Vector, Pathogen, Viral replication and Viral evolution.

He combines subjects such as Neonicotinoid, Virus, Hemolymph and Vector with his study of Varroa. His studies in Sialome integrate themes in fields like Host and Parasitism. His Parasitoid study in the realm of Host interacts with subjects such as Generalist and specialist species.

Between 2017 and 2021, his most popular works were:

  • Transcriptome and Metabolome Reprogramming in Tomato Plants by Trichoderma harzianum strain T22 Primes and Enhances Defense Responses Against Aphids (23 citations)
  • Haemolymph removal by Varroa mite destabilizes the dynamical interaction between immune effectors and virus in bees, as predicted by Volterra's model. (21 citations)
  • Honey Bee Antiviral Immune Barriers as Affected by Multiple Stress Factors: A Novel Paradigm to Interpret Colony Health Decline and Collapse. (21 citations)

In his most recent research, the most cited papers focused on:

  • Gene
  • Genetics
  • Bacteria

His primary areas of study are Immune system, Evolutionary biology, Spodoptera littoralis, Trichoderma and Deformed wing virus. His studies deal with areas such as Parasitoid, Genome, Multiple stress, Mutualistic symbiosis and Honey bee as well as Evolutionary biology. His Parasitoid study is concerned with Biological pest control in general.

His study in Trichoderma is interdisciplinary in nature, drawing from both Genetics, Trichoderma harzianum, Transcriptome, Aphid and Plant defense against herbivory. His Deformed wing virus research incorporates elements of Virus, Virology, Vector and Colony Collapse. His Varroa destructor research includes themes of Hemolymph and Varroa.
