Research.com Recognitions

  • 2025 - Research.com Plant Science and Agronomy in United Kingdom Leader Award
  • 2022 - Research.com Plant Science and Agronomy in United Kingdom Leader Award
  • 2014 - Member of the National Academy of Sciences
  • 2008 - Wolf Prize in Agriculture for their remarkable discoveries of mechanisms governing plant-insect and plant-plant interactions. Their scientific contributions on chemical ecology have fostered the development of integrated pest management and significantly advanced agricultural sustainability.
  • 1996 - Fellow of the Royal Society, United Kingdom

Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Insect

His primary scientific interests are in Botany, Aphid, Pheromone, Agronomy and Sex pheromone. His study on Botany is mostly dedicated to connecting different topics, such as Host. His Aphid research includes themes of PEST analysis, Acyrthosiphon pisum, Aphididae and Olfactometer.

His Pheromone study integrates concerns from other disciplines, such as Odorant binding, ALARM, Apidae, Coccinella septempunctata and Honey bee. In general Agronomy, his work in Desmodium, Stemborer and Poaceae is often linked to Pennisetum purpureum linking many areas of study. His Sex pheromone study also includes fields such as

  • Ecology which intersects with area such as Signalling,
  • Nepetalactol which connect with Zoology.

His most cited work include:

  • The Use of Push-Pull Strategies in Integrated Pest Management (924 citations)
  • Stressful 'memories' of plants: evidence and possible mechanisms (529 citations)
  • Perception of plant volatile blends by herbivorous insects – Finding the right mix (447 citations)

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

Botany, Aphid, Pheromone, Sex pheromone and Agronomy are his primary areas of study. His Botany research includes elements of Host, Olfactometer and Horticulture. His Aphid research integrates issues from Rhopalosiphum padi, Aphididae, Predation and Semiochemical.

The Pheromone study combines topics in areas such as ALARM and Culex quinquefasciatus. His Sex pheromone research incorporates elements of Nepetalactol, Ecology and Stereochemistry. His study in the field of Striga, Desmodium, Striga hermonthica and Stemborer also crosses realms of Pennisetum purpureum.

He most often published in these fields:

  • Botany (35.98%)
  • Aphid (19.29%)
  • Pheromone (15.87%)

What were the highlights of his more recent work (between 2012-2021)?

  • Botany (35.98%)
  • Agronomy (13.27%)
  • PEST analysis (9.99%)

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

John A. Pickett mainly focuses on Botany, Agronomy, PEST analysis, Aphid and Agriculture. His Botany study which covers Olfactometer that intersects with Horticulture. His studies in PEST analysis integrate themes in fields like Chemical ecology and Infestation.

His Aphid research incorporates themes from DIMBOA, Host, Nutrient and Rhopalosiphum padi. Within one scientific family, John A. Pickett focuses on topics pertaining to Insect under Pheromone, and may sometimes address concerns connected to Semiochemical. His Sex pheromone study incorporates themes from Acanthoscelides obtectus and Ecology, Biological pest control.

Between 2012 and 2021, his most popular works were:

  • Averting a malaria disaster: will insecticide resistance derail malaria control? (219 citations)
  • Underground signals carried through common mycelial networks warn neighbouring plants of aphid attack (204 citations)
  • Achieving food security for one million sub-Saharan African poor through push–pull innovation by 2020 (117 citations)

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

  • Botany
  • Ecology
  • Gene

John A. Pickett mainly investigates Botany, Agriculture, Agronomy, Aphid and Host. John A. Pickett combines subjects such as Plant defense against herbivory and Elicitor with his study of Botany. His study in Agriculture is interdisciplinary in nature, drawing from both Agroforestry, Crop protection, Natural resource economics and Sustainability.

As a part of the same scientific family, he mostly works in the field of Agronomy, focusing on Monocropping and, on occasion, Crotalaria, Fodder, Sowing and Fall armyworm. His Aphid research integrates issues from Chemical signalling, Gene, Insect, Nutrient and Mycelium. His work investigates the relationship between Crop and topics such as Pheromone that intersect with problems in Zoology.
