Research.com Recognitions

  • 2026 - Research.com Plant Science and Agronomy in Kenya Leader Award
  • 2025 - Research.com Plant Science and Agronomy in Kenya Leader Award

Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Agriculture

Sunday Ekesi mainly investigates Botany, Tephritidae, Metarhizium anisopliae, Bactrocera invadens and Ecology. The study of Botany is intertwined with the study of Horticulture in a number of ways. Tephritidae connects with themes related to Host in his study.

His biological study spans a wide range of topics, including Beauveria bassiana, Entomopathogenic fungus, Inoculation and Ceratitis capitata. His research in Bactrocera invadens intersects with topics in Entomology, Mangifera and Taxon. His PEST analysis research is multidisciplinary, incorporating elements of Zoology and photoperiodism.

His most cited work include:

  • Field infestation, life history and demographic parameters of the fruit fly Bactrocera invadens (Diptera: Tephritidae) in Africa. (142 citations)
  • Synonymization of key pest species within the Bactrocera dorsalis species complex (Diptera: Tephritidae): taxonomic changes based on a review of 20 years of integrative morphological, molecular, cytogenetic, behavioural and chemoecological data (140 citations)
  • African edible insects for food and feed: inventory, diversity, commonalities and contribution to food security (136 citations)

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

His primary scientific interests are in Botany, Horticulture, PEST analysis, Metarhizium anisopliae and Tephritidae. His work on Larva, Ceratitis capitata and Endophyte as part of general Botany study is frequently connected to Capitata, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. The various areas that Sunday Ekesi examines in his Larva study include Fecundity and Animal science.

Sunday Ekesi interconnects Hemiptera, Lepidoptera genitalia, Integrated pest management and Ecology in the investigation of issues within PEST analysis. In Metarhizium anisopliae, Sunday Ekesi works on issues like Beauveria bassiana, which are connected to Biopesticide. His study in Tephritidae is interdisciplinary in nature, drawing from both Zoology and Mangifera.

He most often published in these fields:

  • Botany (29.00%)
  • Horticulture (25.00%)
  • PEST analysis (20.00%)

What were the highlights of his more recent work (between 2019-2021)?

  • PEST analysis (20.00%)
  • Horticulture (25.00%)
  • Bactrocera dorsalis (8.00%)

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

His primary areas of investigation include PEST analysis, Horticulture, Bactrocera dorsalis, Integrated pest management and Ecology. His PEST analysis study incorporates themes from Hemiptera, Infestation and Metarhizium anisopliae. As part of one scientific family, Sunday Ekesi deals mainly with the area of Horticulture, narrowing it down to issues related to the Biopesticide, and often Beauveria bassiana.

Bactrocera dorsalis is the subject of his research, which falls under Tephritidae. His Tephritidae research is multidisciplinary, relying on both Zoology, Hymenoptera and Introduced species. His Botany study frequently links to related topics such as Acrididae.

Between 2019 and 2021, his most popular works were:

  • Effects of Traditional Processing Techniques on the Nutritional and Microbiological Quality of Four Edible Insect Species Used for Food and Feed in East Africa. (13 citations)
  • Prediction of breeding regions for the desert locust Schistocerca gregaria in East Africa. (10 citations)
  • Distribution of Candidatus Liberibacter species in Eastern Africa, and the First Report of Candidatus Liberibacter asiaticus in Kenya. (7 citations)

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

  • Ecology
  • Botany
  • Agriculture

Sunday Ekesi spends much of his time researching PEST analysis, Ecology, Integrated pest management, Hermetia illucens and Tephritidae. His PEST analysis study combines topics in areas such as Beauveria bassiana, Lepidoptera genitalia and Outbreak. His Lepidoptera genitalia study integrates concerns from other disciplines, such as Bassiana, Horizontal transmission and Conidium, Metarhizium anisopliae.

His work in the fields of Mealybug, Paracoccus marginatus and Species distribution overlaps with other areas such as Risk assessment and Identity. The Integrated pest management study combines topics in areas such as Ecological distribution, Candidatus Liberibacter, Crop and Data sequences. Sunday Ekesi usually deals with Tephritidae and limits it to topics linked to Infestation and Agriculture.
