Dadala, an associate professor in the Department of Sericulture in Tirupati, India, was notified of the honor Oct. 18. She is expected to begin her eight-month Fulbright-Nehru-2013 senior research fellowship in August.
“This is a highly competitive and a huge honor,” said Hammock, a distinguished professor of entomology. "We are thrilled to have her back as part of the laboratory family."
Specifically, Dadala is researching genes for insect specific enzymes that metabolize the juvenile hormone (JH) and how they can be expressed to develop recombinant baculovirus.
During the 35-minute oral interview, she was asked: “Baculovirus expression can be done in India, too, in many labs. How do you justify?”
“Yes, it’s true,” she told them, “but beyond baculovirus expression, I'm looking for the able mentorship of Professor Bruce Hammock, to study and explore the endogenous role of JHEH (Juvenile Hormone Epoxide Hydrolase) protein which can be further brought forth as a biopesticide.”
“They were well pleased with the answer,” Dadala told Hammock in an email.
“Further, looking at my application and your consent letter, one of the board members said ‘Your mentor seems to be a very big guy in the United States.”
Dadala told them “very true. It’s my privilege to get his consent and learn from him.”
Dadala, a researcher in the Hammock lab from July 13, 2007 through June 8, 2008, is the lead author of Integrated Insect Pest Management-Physiological and Molecular Approaches, with Sreedevi Kolla. Of the 148-page book, published by VDM Publishing, they wrote: “The agricultural land is becoming a scarce resource with increased pressure of population wherein ways to enhance the crop productivity needs to be strengthened. One of the focuses is to curb the crop losses due to insect pests in a sustainable manner. The alarming and detrimental effects of chemical pesticides on environment and non target organisms, integrated pest management has been evolved with viable, benign and ecofriendly strategies. As juvenile hormone (JH) plays an important role in insect's physiology and reproduction, the systems (metamorphosis, moulting and reproduction) related to JH are potential targets of pest management. Genes for insect specific enzymes that metabolize JH can be expressed to develop recombinant baculovirus, which can disrupt physiology and in turn becomes detrimental to the pest itself. Further, the role of JH binding protein, Ecdysone receptor proteins are also explored for biocontrol strategies. Development of novel recombinant baculovirus biopesticide and its applicability are discussed.”
She is also a co-author of “The Role of a- and b-hydrolase Fold Enzymes as Biopesticides in Pest Management” published last year in the Journal of Biopesticides. It is online at

Hammock, who has a joint appointment with the UC Davis Comprehensive Cancer Center, directs the campuswide Superfund Research Program, the National Institutes of Health Biotechnology Training Program and the NIEHS Combined Analytical Laboratory. He is a Fellow of the Entomological Society of America, a member of the prestigious National Academy of Sciences, and the recipient of the UC Davis Faculty Research Lecture Award in 2001 and the Distinguished Teaching Award for Graduate and Professional Teaching in 2008.

The organizers promise “an afternoon of lively discussions, unique tastings and interesting displays on the science behind honey and the non-honey bee pollinators.”
Tickets are $60 per person. Friends of RMI, faculty, staff and students will be admitted for $50. For online registration and other information, see the RMI website.
For the honey competition, any beekeeper can drop off a jar of honey, with a business card and a summary of the honey to the RMI office on Wednesday, Oct. 24. There is no charge to enter the honey competition, said RMI event coordinator Tracy Dickinson
RMI executive director Clare Hasler-Lewis said the newly established Honey and Pollination, was approved earlier this year by the College of Agricultural and Environmental Sciences. The vision is to “make UC Davis the nation’s leading authority on honey, honey bees and pollination by combining the resources and expertise of RMI and the Department of Entomology’s Harry H. Laidlaw Jr. Honey Bee Research Facility.”
The center’s mission is “to showcase the importance of honey and pollination to the well-being of the citizens of California. The center will spearhead and nucleate efforts to gain support and assembly teams for research, education and outreach programs for various stakeholder groups including the beekeeping industry, agricultural interests who depend on bee pollination, backyard beekeepers and the food industry."
The goals:
• Expand research and education concerning nutrition, health, quality and appreciation of honey
• Develop useful information for California’s agricultural bounty that depends on insect pollination
• Help the honey industry establish labeling guidelines to guarantee pure and unadulterated varietal honey
• Coordinate a multidisciplinary team of experts in honey production, pollination and bee health
• Promote the use of locally procured honey in the home, food industry and restaurants.

DAVIS--Micky Eubanks, professor of entomology at Texas A&M University, will speak on “Community Ecology of a ‘Pest’: Aphids Rule Their World Via Powerful Indirect Effects” at the UC Davis Department of Entomology seminar on Wednesday, Oct. 24 in Room 1022 of the Life Sciences Building.
His seminar, set from 12:10 to 1 p.m., is the second in a series of noonhour seminars. He will be introduced by his host, graduate student Billy Krimmel.
Eubanks received his bachelor’s degree and master’s degree in biology from the University of Mississippi and his doctorate in entomology from the University of Maryland.
Prior to moving to Texas A&M University, Eubanks was a postdoctoral fellow at Bucknell University and an assistant and associate professor at Auburn University. Eubanks is broadly interested in the community and evolutionary ecology associated with plant-insect interactions. Much of his research focuses on understanding variation in the strength of species interactions.
The Eubanks lab, he says, seeks to understand “keystone” interactions that explain a disproportionately large amount of variation in the abundance and distribution of species. “Understanding these interactions is critical if we are to accurately predict the outcome of species interactions in diverse and highly connected ecosystems and maintain ecological sustainability in a world where human impacts increase daily.”
The UC Davis Department of Entomology fall seminars are coordinated by assistant professors Joanna Chiu and Brian Johnson. Through the coordination of professor James R. Carey, this seminar will be videotaped and posted on UCTV.

This is the first in the fall seminar series sponsored by the UC Davis Department of Entomology. Brian Johnson, assistant professor of entomology, will serve as the host for the Oct. 17 seminar. He and assistant professor Joanna Chiu are coordinating the seminars.
"Individuals in insect societies are inextricably linked by social interactions,” Linksvayer writes in his abstract. “Colony-level social networks coordinate individual function and colony homeostasis just as physiological networks coordinate tissue function and homeostasis within individuals. As a result, social insect colonies are often described as ‘superorganisms’ composed of organisms that function together more-or-less as a unit. This characteristic is thought to have led to the remarkable ecological and evolutionary success of the social insects. Despite these conspicuous superorganismal properties and the inherent hierarchical organization of life in insect societies (i.e. colony-level, organismal-level), most previous studies of the evolutionary genetic and molecular basis of social insect traits use the same reductionist approaches that have been developed for solitary organisms, where an individual’s traits are only influenced by its own genome. More realistically, in social organisms, an individual’s traits are the property of the genomes of all social group members. I will discuss ongoing integrative research studying how social interactions in ants and honey bees affect the expression and evolution of individual- and group-level traits."
Linksvayer, appointed assistant professor at the University of Pennsylvania in 2011, received his bachelor’s degree in biology from Carleton College, Northfield, Minnesota, in 1998, and his doctorate in evolution, ecology and behavior from Indiana University in 2005. He did his postdoctoral work in evolutionary biology at Arizona State University from 2005 to 2008, and in social evolution from the University of Copenhagen in 2011.
Through the coordination of professor James R. Carey, this seminar will be videotaped and later posted on UCTV.
