Overview

What is she best known for?

The fields of study she is best known for:

Ecology
Botany
Agriculture

Ingrid H. Williams focuses on Agronomy, Pollination, Botany, Meligethes aeneus and Ecology. Her Agronomy research is multidisciplinary, incorporating perspectives in PEST analysis and Larva. When carried out as part of a general Pollination research project, her work on Pollination management is frequently linked to work in Value, therefore connecting diverse disciplines of study.

The concepts of her Meligethes aeneus study are interwoven with issues in Biological pest control, Integrated pest management and Pollen beetle. Her Brassica research is multidisciplinary, relying on both Oil seed and Weevil. Her work carried out in the field of Apidae brings together such families of science as Pheromone, Honey bee and Pollinator.

Her most cited work include:

A landscape‐scale study of bumble bee foraging range and constancy, using harmonic radar (395 citations)
Bees and the Pollination of Crops and Wild Flowers in the European Community (314 citations)
The conservation of bees. (232 citations)

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

Her primary scientific interests are in Agronomy, Botany, Horticulture, Ecology and Pollination. Her study in Agronomy focuses on Crop, Brassica, Weevil, Integrated pest management and Meligethes aeneus. Her Integrated pest management research incorporates themes from PEST analysis and Biological pest control.

Her Meligethes aeneus research is multidisciplinary, incorporating elements of Trap crop and Pollen beetle. Foraging is the focus of her Ecology research. Her biological study spans a wide range of topics, including Agroforestry, Insect and Cultivar.

She most often published in these fields:

Agronomy (34.73%)
Botany (22.45%)
Horticulture (14.62%)

What were the highlights of her more recent work (between 2009-2020)?

Agronomy (34.73%)
Botany (22.45%)
Biological pest control (9.66%)

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

The scientist’s investigation covers issues in Agronomy, Botany, Biological pest control, Ecology and Overwintering. Her Botany study integrates concerns from other disciplines, such as Metabolic rate and Animal science. Her study in Biological pest control is interdisciplinary in nature, drawing from both Pesticide, Host, Toxicology and Integrated pest management.

Ecology and Phytophthora infestans are commonly linked in her work. Her Weevil study also includes

Pollen beetle together with Meligethes aeneus,
Pest control, which have a strong connection to Crop protection. Her Crop research focuses on subjects like Agroforestry, which are linked to Nectar, Pollination, Inflorescence, Ecological succession and Push–pull strategy.

Between 2009 and 2020, her most popular works were:

The Major Insect Pests of Oilseed Rape in Europe and Their Management: An Overview (87 citations)
Biocontrol-based integrated management of oilseed rape pests (75 citations)
Parasitoids of Oilseed Rape Pests in Europe: Key Species for Conservation Biocontrol (35 citations)

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

Ecology
Botany
Agriculture

Her primary areas of investigation include Agronomy, Parasitoid, Biological pest control, Parasitism and Botany. Her Weevil study in the realm of Agronomy interacts with subjects such as Nitrogen fixation. Her Weevil research is multidisciplinary, incorporating perspectives in Brassica and Flea beetle.

The various areas that she examines in her Biological pest control study include Host, Entomovector, Integrated pest management and Crop. Her Parasitism research includes elements of PEST analysis, Meligethes aeneus, Agriculture and Insect. Her Foraging study, which is part of a larger body of work in Ecology, is frequently linked to Air temperature, bridging the gap between disciplines.
