Insects have eaten plants for around 400 million years. These interactions have given rise to most of terrestrial biodiversity. Over the past 12,000 years, humans have disrupted plant-herbivore relationships by building cities, domesticating crops, and changing the global climate. I investigate these disruptions, focusing on species that are of cultural importance, such as street trees, crops, crop wild relatives, and plants that support rare insect species. My work combines experiments, observations, citizen science, and biological collections to address key hypotheses in ecology.
Research in my laboratory focuses on using phylogenetic trees inferred from nucleotide sequence data as a framework to understand biodiversity, morphological evolution, molecular evolution, and certain aspects of disease ecology. Many of my research questions focus on nematodes (both free-living and parasitic), although I also study other groups of parasites, including acanthocephalans. The main source of my laboratory funding comes from the National Science Foundation, and these research grants are often collaborative, involving investigators at UC Riverside (Jim Baldwin, Paul De Ley) and other institutions. Much of my recent evolutionary research has focused on nematodes of the suborder Cephalobina, a group that includes numerous bacterial-feeding species in soil, but also some parasitic taxa hosted by invertebrates, and more rarely mammals.
Dr. Nansen's research interests include: Insect Ecology, IPM, Remote Sensing, host plant stress detection, host selection by arthropods, pesticide performance, and use of reflectance-based imaging in a wide range of research applications.
Dr. Niño's research interests include: Honey Bee Biology, Health, and Breeding, Behavior, Reproductive Physiology, Genomics, Chemical Ecology, Sociology of Beekeeping.
Dr. Rosenheim's research interests include: Insect ecology, with a focus on host-parasitoid, predator-prey, and plant-insect interactions interactions, with direct applications to biological control.
Research in the Siddique lab focuses on basic as well as applied aspects of interaction between parasitic nematodes and their host plants. The long-term object of our research is not only to enhance our understanding of molecular aspects of plant–nematode interaction but also to use this knowledge to provide new resources for reducing the impact of nematodes on crop plants in California.
As a faculty member in the Department of Entomology and Nematology, my area of research responsibility encompasses insect/virus/plant interactions and development of management strategies for insect-transmitted plant pathogens. I have worked with many insect vector species (thrips, aphids, whiteflies, leafhoppers, mealybugs) and the plant pathogens they transmit, including viruses, phytoplasma and bacteria. During the past 30 years I have delved deeply into world of thrips and the tospoviruses they transmit. My work has ranged from the organismal to the molecular and I have had the opportunity to range across disciplinary borders, working with entomologists, virologists, plant physiologists and plant breeders. Currently, I am exploring the interaction between the Western flower thrips and the plant virus, Tomato spotted wilt virus (TSWV). I lead an AFRI NIFA Coordinated Agricultural Project addressing development of innovative strategies for management of thrips vectors and Tospoviruses and am a co-PI on a NSF grant aimed at revealing the early events in Sw-5 mediated resistance to TSWV in tomato.
All plants are colonized by microorganisms that influence plant traits and interactions with other species, including insects that consume or pollinate plants. I am interested in the basic and applied aspects of microbial contributions to the interaction between plants and insects. I also use these systems to answer basic ecological questions, such as what mechanisms influence plant biodiversity and trait evolution.
