Alvarez, Anne M

Plant Pathologist, Emeritus
  

Email:  alvarez@hawaii.edu
Phone:  956-7764
Interests:  
  • Population diversity: Genetic, serological, and biochemical studies are undertaken to identify virulent subpopulations of bacteria and to show phylogenetic relationships among strains in selected species of plant pathogenic bacteria.
  • Diagnostics: Based on diversity of plant pathogens, our lab focuses on development and application of specific immunodiagnostic and DNA-based assays for detection and identification of pathogens distributed worldwide in seeds and plant propagative materials. We also work on development of biosensors and hand-held tracking systems for monitoring invasive species in mixed microbial populations.
  • Epidemiology: The tracking devices are used to determine primary sources of inoculum for bacterial diseases of tropical crops. We are currently working on pathogenic strains of bacteria that cause bacterial canker of tomato, anthurium blight, ginger wilt, and pineapple heart rot.
  • Biological control: A consortium of beneficial bacterial species has been developed that reduces the incidence and spread of anthurium blight. We are currently studying the effects of beneficial bacteria on disease, including their role in preventing the pathogen from colonizing foliar and vascular tissues. Host-pathogen interactions are studied using immunodiagnostic and DNA-based detection methods in plant tissues. A genetically modified bioluminescent strain of the anthurium blight pathogen is also used for determining effects of beneficial bacteria in preventing the infection process.

Grace, J Kenneth

Researcher Emeritus
  

Email:  kennethg@hawaii.edu
Phone:  956
Interests:  

A faculty member in the College of Tropical Agriculture and Human Resources (CTAHR) from 1990 until his retirement in December 2017, Dr. Grace served as Associate Dean and Associate Director for Research from 2014-2017, with overall responsibility for the college's $20 million+ research portfolio. Prior to this, he served as Interim Associate Dean/Director for Research (2011-2014), Special Research Director (2010-2011), and Chair of the Department of Plant and Environmental Protection Sciences (PEPS) (2001-2010).

Prior to joining the University of Hawaii, Dr. Grace was Director of the Urban Entomology Program in the Faculty of Forestry at the University of Toronto (1986-1990). He was employed in the pest control industry in California from 1975-1986, where he first became interested in pursuing a career in entomology (the study of insects).

As an entomologist, Dr. Grace’s personal research interests include the biology, behavior, ecology and management of urban and structural pests, with an emphasis on termites and wood protection. He has published over 290 technical articles, and has been a frequent invited speaker at national and international conferences and symposia. Dr. Grace has served as a member of the Pest Control Advisory Committee of the State of Hawaii Regulated Industries Complaints Office, a member of the Pest Control Board of the Department of Commerce and Consumer Affairs, an executive committee member of the Coffee Berry Borer Task Force, the university's representative on the inter-agency Hawaii Invasive Species Council, a member of the National Technical Advisory Committee for Project Full-Stop (USDA-ARS), and as international adviser to the Institute for Sustainable Human-habitability, Kyoto University.

Hara, Arnold H

Entomologist
  

Email:  arnold@hawaii.edu
Phone:  969-8214
Interests:  
Dr. Hara has been with the University of Hawaii for over 25 years focusing on insect and mite pests of agricultural and floricultural crops, elucidating the bionomics of these pests, and developing pest management programs that minimize the use of chemical pesticides. Dr Hara innovate preharvest and postharvest control treatments in a systems approach to quarantine security for floricultural crops to meet stringent interisland, interstate and foreign quarantine regulations. Some of his research accomplishments include the development of heat treatments to control quarantine pests, including the invasive coqui frog.

Hu, John

Plant Pathologist
  

Email:  johnhu@hawaii.edu
Phone:  956-7281
Interests:  
  • Banana bunchy top virus (BBTV) is the most devastating virus disease of bananas. The virus is transmitted by the banana aphid (Pentalonia nigronervosa) in a persistent manner. New growth from infected plants is stunted and distorted, resulting in a characteristic "bunchy top" appearance. No fruit is produced on infected plants, and a high incidence of BBTV in production areas can cause complete yield loss. Specific objectives of this project are: (1) to develop rapid, sensitive, and reliable assays for detection of BBTV in plants and insects; (2) to characterize the genome organization and vector transmission of BBTV; and (3) to develop resistant transgenic banana plants to control BBTV.
  • Mealybug wilt of pineapple (MWP) is a devastating disease found in all the pineapple-growing regions of the world. The disease is characterized by severe leaf tip dieback, downward curling of the leaf margins, and reddening and wilting of the leaves that can lead to total collapse of the plant. Specific objectives of this project include: (1) to develop rapid detection assays for the closterovirus; (2) to study the cause (etiology) of MWP; (3) to examine the epidemiology of the virus; and (4) to develop alternative, environmentally sound strategies to manage MWP.

Phone:  956-6745
Interests:  
My research program is designed to be both integrated and applied. I am broadly interested in how the landscape can be designed and enhanced to promote pollinator health, particularly by adding flowering plants that meet the nutritional needs of honey bees and other pollinators. I am also working on building an extension program at UH that will provide information to farmers, beekeepers, and the general public on the best management practices for pollinator conservation and agricultural sustainability.

Interests:  

Research Interests:

My lab is interested in dissecting the molecular basis specifying pathogen virulence and plant resistance in order to develop novel disease control strategies. We mainly focus on vegetable and fruit diseases caused by fungi and oomycetes. Our current research involves two oomycete pathogens Phytophthora palmivora and Peronospora belbahrii, and one fungal pathogen Corynespora cassiicola. Peronospora belbahrii is an obligate biotrophic pathogen that causes basil downy mildew, a foliar disease threatening sweet basil production worldwide. Phytophthora palmivora has a very broad host range with over 1000 plant species, including many economically important hosts such as papaya, cacao, rubber tree, citrus, coconut and black pepper. Corynespora cassiicola is known as a pathogen of many important agricultural crops, such as cucumber, tomato, papaya, soybean and cowpea. We are using various genetic, genomic, molecular, biochemical and plant pathology approaches in our research with an ultimate goal to develop novel effective environmental friendly disease control strategies. In addition to basic research, we are also interested in translational and applied research to translate discoveries from basic science to practical disease control measures.

Interests:  
My research program addresses the development of environmentally sound pest management options, with emphasis on tropical fruit and nut crops. My main research interest is biological control and its integration with other pest management options. A major component of my interest in biological control understanding how to quantify non-target risks and to plan introductions of biological control agents to have minimal impact on indigenous species, yet maximal impact upon pest populations. Insect conservation is another of my research interests. Hawai'i provides an interesting location for the study of impacts of agriculture and other disturbances on endemic species. I hope to one day launch some projects on patterns of gall-insect diversity in the islands. Extension projects include developing sampling plans and thresholds for pests of bananas and macadamia nuts, and training growers in IPM approaches, sampling and insect identification for the purpose of pest scouting.
