Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Horticulture

Codling moth, Botany, Tortricidae, Horticulture and Sex pheromone are his primary areas of study. His biological study spans a wide range of topics, including Insect and Pheromone. His work in Botany addresses subjects such as Orchard, which are connected to disciplines such as Canopy.

His research in Tortricidae intersects with topics in Fruit tree and Mating disruption. His study in the field of PEAR is also linked to topics like Drosophila suzukii and White. He works mostly in the field of Sex pheromone, limiting it down to topics relating to Mating and, in certain cases, Olfaction, as a part of the same area of interest.

His most cited work include:

  • A pear-derived kairomone with pheromonal potency that attracts male and female codling moth, Cydia pomonella (L.). (216 citations)
  • Particle Films for Suppression of the Codling Moth (Lepidoptera: Tortricidae) in Apple and Pear Orchards (99 citations)
  • Effects of a Kaolin-Based Particle Film on Obliquebanded Leafroller (Lepidoptera: Tortricidae) (84 citations)

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

Alan L. Knight mainly focuses on Codling moth, Horticulture, Tortricidae, Botany and Sex pheromone. Alan L. Knight has researched Codling moth in several fields, including Malus, Toxicology, Kairomone and PEAR. The various areas that Alan L. Knight examines in his Horticulture study include Canopy and Trapping.

His Tortricidae research incorporates themes from Fruit tree, Mating disruption and Orchard. The study incorporates disciplines such as Orange and Animal science in addition to Botany. His Sex pheromone study integrates concerns from other disciplines, such as Pest control, Mating and Grapholita molesta.

He most often published in these fields:

  • Codling moth (74.29%)
  • Horticulture (69.29%)
  • Tortricidae (69.29%)

What were the highlights of his more recent work (between 2013-2021)?

  • Tortricidae (69.29%)
  • Lepidoptera genitalia (51.43%)
  • Sex pheromone (57.86%)

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

His main research concerns Tortricidae, Lepidoptera genitalia, Sex pheromone, Horticulture and Codling moth. Botany covers Alan L. Knight research in Lepidoptera genitalia. His Sex pheromone study combines topics in areas such as Pest control, Pome, Kairomone and Grapholita molesta.

His research investigates the connection between Kairomone and topics such as Zoology that intersect with issues in Insecticide resistance and Economic threshold. His work in the fields of PEST analysis overlaps with other areas such as Metschnikowia pulcherrima. His Codling moth study incorporates themes from Malus, Toxicology, PEAR, Choristoneura rosaceana and Orchard.

Between 2013 and 2021, his most popular works were:

  • Use of Glacial Acetic Acid to Enhance Bisexual Monitoring of Tortricid Pests With Kairomone Lures in Pome Fruits (30 citations)
  • Caterpillar-induced plant volatiles attract conspecific adults in nature. (24 citations)
  • Emission of volatile compounds from apple plants infested with Pandemis heparana larvae, antennal response of conspecific adults and preliminary field trial (21 citations)

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

  • Ecology
  • Botany
  • Agriculture

His scientific interests lie mostly in Tortricidae, Sex pheromone, Lepidoptera genitalia, Horticulture and Kairomone. His Sex pheromone research integrates issues from Codling moth and Grapholita molesta. The concepts of his Codling moth study are interwoven with issues in Mating disruption, Toxicology and PEAR.

His research ties Larva and Lepidoptera genitalia together. In his research on the topic of Horticulture, Nocturnal is strongly related with Botany. He focuses mostly in the field of Kairomone, narrowing it down to matters related to Spilonota ocellana and, in some cases, Zoology, Caterpillar and Herbivore.
