Larry Godfrey to Address California Rice Field Day on Aug. 31Larry Godfrey of the UC Davis Department of Entomology and Nematology will speak on “The Rice Insecticides: Maximize Use of IPM Tactics to Conserve These Products” at the annual California Rice Field Day, set Wednesday, Aug. 31 at the Rice Experiment Station, Biggs.
Godfrey, who has addressed Rice Field Day for 25 years, will discuss how the California rice industry's use of insecticides is threatened by two major factors: the development of insecticide resistance and regulatory actions.
Joanna Bloese, a student in the Godfrey lab, will present a poster, "Evaluating the Effects of Chemical and Cultural Management Practices on the Population Dynamics of Tadpole Shrimp (Triops longicaudatus) in California Rice." (Research by J. B. Bloese, L. Espino, K. Goding, L. D. Godfrey). Ongoing research is focused on developing pest management methods in rice to reduce the need for insecticide use while still producing a profitable crop. -more-
Systemic Insecticides May Not Work as Well During Drought--Christian NansenChristian Nansen.
“Weather patterns associated with climate change may adversely affect the performance of some of the most important insecticides, systemic insecticides, against coleopteran and lepidopteran pests,” Nansen says.
“These insecticides depend on efficient water and nutrient uptake through the root system and on vascular flow – both mechanisms may be partially compromised under drought conditions,” Nansen points out. “This leads to lower uptake and non-uniform distribution of systemic insecticide in plant tissues – and therefore, higher risk of pests NOT acquiring a lethal dosage.” -more-
Bruce Hammock: From Caterpillars to Butterflies to Kidney Disease
Bruce Hammock, UC Davis distinguished professor of entomology who holds a joint appointment with the UC Davis Comprehensive Cancer Center, is featured in a news story, "From Caterpillars to Kidney Disease: Surprise Discoveries in Basic Science," on the Medical College of Wisconsin, Milwaukee, website.
It chronicles how Hammock's basic research on caterpillars--how caterpillars become butterflies--led to key discoveries about chronic pain, including diabetic pain.
It includes information on Hammock's collaborator, John Imig, professor of pharmacology and toxicology at the Medical College of Wisconsin, who recently received a $2.3 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases "to investigate the development of a drug to treat type 2 diabetes and metabolic syndrome." -more-
Three Receive Hazeltine Student Research Awards
For the second consecutive year, UC Davis graduate students Sandy Olkowski, Stephanie Kurniawan and Maribel "Mimi" Portilla are recipients of the Bill Hazeltine Student Research Awards, memorializing a medical entomologist who worked tirelessly in mosquito research. The three recently lunched at a Davis restaurant with Hazeltine's sons, Craig of Scottsdale, Ariz.,and Lee Hazeltine of Woodland. The graduate students discussed their research and goals and thanked them for the Hazeltine family's support. -more-
UC IPM Develops 'Bee Precaution Pesticide Ratings'Bee Precaution Pesticide Ratings to help pest managers make an informed decision about how to protect bees when choosing or applying pesticides.
Various insects, birds, and other animals pollinate plants. Bees, especially honey bees, are the most vital for pollinating food crops. Many California crops rely on bees to pollinate their flowers and ensure a good yield of seeds, fruit, and nuts. Pesticides, especially insecticides, can harm bees if they are applied or allowed to drift to plants that are flowering.
The bee precaution ratings are based on the reported effects of a pesticide's active ingredient on adult honey bees or their brood. You can find and compare ratings for active ingredients including acaricides (miticides), bactericides, fungicides, herbicides, and insecticides. -more-
Meredith Cenzer: What Happens When Soapberry Bugs Switch Hosts
Now newly published UC Davis research shows that soapberry bugs have not only lost adaptations to their native host plant but are regionally specializing on an invasive host.
The work, "Adaptation to an Invasive Host Is Driving the Loss of a Native Ecotype," published in the current edition of the journal Evolution, “collapses a classic and well-documented example of local adaptation,” said doctoral candidate Meredith Cenzer of the Louie Yang lab, UC Davis Department of Entomology and Nematology. The plant-host switch can lead to disruption of native plant communities and a breakdown of the ecosystem. -more-
UC Davis Toxicologist Shirley Gee: 40 Years of Service
If you preface her name with “research scientist” or “renowned toxicologist,” followed by “40 years of service at UC Davis,” those words don't even begin to describe her or her work.
Shirley Gee, principal investigator, lecturer, mentor and the longtime manager of the Bruce Hammock research lab, UC Davis Department of Entomology and Nematology, retired June 30, leaving a long chain of accomplishments, admiration, appreciation and affection extending locally, nationally and globally.
Gee, who joined the Hammock lab in 1985, managed a team of researchers that annually included some 40 scientists: graduate students, technicians, post graduates and visiting professors from all over the world.
“Forty seems like a crazy big number,” Gee said, “and I am a little overwhelmed by it (the number).” -more-
UC Davis Medical Entomologist: Novel Way to Render Female Mosquitoes InfertileAnthony Cornel, Ph.D. is targeting the potential spread of the Zika virus mosquito vector, Aedes aegypti, using a novel control strategy that renders the female mosquitoes sterile.
Male Aedes aegypti mosquitoes infected with a bacterium, Wolbachia pipientis, are being released in Clovis, Fresno County, where this mosquito was discovered in June 2013. Although this mosquito is now found in California, there has been no locally transmitted case of the Zika virus in the state.
The project, to determine dispersal and survival, began Monday, May 10.
“The daytime-biting mosquito, which feeds predominantly on humans, has spread to at least seven counties since its discovery in Clovis,” said Cornel, a mosquito researcher and faculty member with the UC Davis Department of Entomology and Nematology and the UC Kearney Agricultural Research and Extension Center, Parlier.
“The biting nuisance and potential of the mosquito Aedes aegypti to transmit Zika, Chikungunya and dengue viruses in California is cause for concern,” he said. “Efforts to curb its spread and reduce populations have not been very effective. Control efforts have included educating the public to remove standing water (source reduction) insecticide barrier sprays and bacterial larviciding.” -more-
