GENOME REVEALS WHY POOP WOULDN’T HURT A FLY

Oct 17, 2014

If you spend most of your time in dung piles and garbage heaps, you better have robust immune genes.  Scientists sequenced the genome of the house fly for the first time and found an expanded number of immune response and defense genes. 

Housefly genome offers clue to human sickness

Oct 17, 2014

Scientists have sequenced the entire genome of the common housefly and say their findings should help uncover new cures for human diseases. The fly can carry some 100 illnesses, including one that can blind. 

House fly genome reveals expanded immune system

Oct 15, 2014

Scientists have sequenced the house fly genome for the first time, revealing robust immune genes, as one might expect from an insect that thrives in pathogen-rich dung piles and garbage heaps.  The research, published Oct. 13 in the journal Genome Biology, will increase understanding of house fly genetics and biology and of how flies quickly adapt to resist insecticides, which could lead to novel control methods.

Study Reveals Dearth of Information on How Flowers Transmit Disease to Bees

Oct 8, 2014

Despite a recent abundance of research on honeybees, bumblebees and the diseases and circumstances that are threatening the world's vital pollinators, there is remarkably little research on the flowers that act as hubs for fungal, bacterial and viral diseases that are transmitted to bees, according to a new study.

 

Study tracks who dengue-carrying mosquitoes bite

Sep 9, 2014

Most people bitten by dengue fever-transmitting mosquitoes in four northwestern Thai villages weren’t residents but visitors, a finding that provides new clues about the spread of the dengue virus.  According to a new study, larger people and adults are bitten significantly more often than smaller people and children.

White House Protects Pollinators (and also the Monarch)

Jun 27, 2014

Monarch butterflies were hibernating in record low numbers in Mexico over the winter, but Cornell Ecologist Anurag Agrawal tells host Steve Curwood that he thinks the numbers breeding in Texas suggest the butterfly making a recovery.

Kill flies by alternating pesticides, monitoring need

Jun 24, 2014

Old-fashioned fly swatters may be the most foolproof housefly killer, but for dairy farms, insecticides are the practical choice. Flies spread disease and a host of pathogens that cost farms hundreds of millions of dollars in annual losses. Unfortunately, with the repeated use of the same insecticides, flies develop resistance through genetic mutations that make these products less effective.

Sex proteins may help fight mosquito-borne diseases

Jun 20, 2014

Better understanding of mosquito seminal fluid proteins – transferred from males to females during mating – may hold keys to controlling the Asian tiger mosquito, the world’s fastest-spreading invasive species, found in the U.S. and elsewhere. This mosquito is an important vector for dengue and chikungunya fevers as well as dog heartworm.

Pests Eat Their Way to Bigger Yields

Jun 20, 2014

Most farmers fight a constant battle against damaging insects. In a plant science version of “keep your friends close but your enemies closer,” Cornell researchers are working with a common potato pest to see if they can activate the natural defenses of potato plants by managing the bugs, rather than eradicating them. 

Identification and Characterization of Seminal Fluid Proteins in the Asian Tiger Mosquito, Aedes albopictus

Jun 19, 2014

Published by Kathryn E. Boes, José M. C. Ribeiro, Alex Wong, Laura C. Harrington, Mariana F. Wolfner and Laura K. Sirot in PLOS Neglected Tropical Diseases 
The Asian tiger mosquito (Aedes albopictus) is an important vector for pathogens that affect human health, including the viruses that cause dengue and Chikungunya fevers. It is also one of the world's fastest-spreading invasive species. For these reasons, it is crucial to identify strategies for controlling the reproduction and spread of this mosquito.

Lyme disease on the rise

May 28, 2014

Lyme disease is a bacterial infection transmitted by deer ticks, which are also known as black-footed ticks. And growing tick populations in Monroe County and other parts of the state are the likely culprit behind the increase in Lyme cases, says Laura Harrington, chair of Cornell University's Entomology Department.

IPM Practices Lead to Healthiest Food

Mar 30, 2014

"Even more than organic production, IPM strives to use the best scientific practices to ensure safe and sustainable agricultural systems. To do this, IPM incorporates practices from conventional and organic production methods, and even biotechnology, a method that has been turned into a bogeyman, but in reality is safer for humans and the environment. IPM has been a national policy for the United States since 1993 and its implementation has resulted in dramatic decreases in the use of harmful pesticides. Much of this decrease has been due to the use of crops produced through biotechnology. As an entomologist whose goal is to develop insect management programs that protect the crop and the environment, I routinely test organic, conventional and biotech practices.  "

Climate, Physiological Tolerance and Sex-Biased Dispersal Shape Genetic Structure of Neotropical Orchid Bees
Molecular Ecology
Margarita M. Lopez-Uribe, Kelly R. Zamudio, Carolina F. Cardoso and Bryan N. Danforth. 
Understanding the impact of past climatic events on the demographic history of extant species is critical for predicting species' responses to future climate change. Palaeoclimatic instability is a major mechanism of lineage diversification in taxa with low dispersal and small geographical ranges in tropical ecosystems. However, the impact of these climatic events remains questionable for the diversification of species with high levels of gene flow and large geographical distributions. In this study, we investigate the impact of Pleistocene climate change on three Neotropical orchid bee species (Eulaema bombiformisE. meriana andE. cingulata) with transcontinental distributions and different physiological tolerances. We first generated ecological niche models to identify species-specific climatically stable areas during Pleistocene climatic oscillations. Read more here.

Predators delay pest resistance to Bt crops

Mar 4, 2014

Crops genetically modified with the bacterium Bt (Bacillus thuringiensis) produce proteins that kill pest insects. Steady exposure has prompted concern that pests will develop resistance to these proteins, making Bt plants ineffective.
Cornell research shows that the combination of natural enemies, such as ladybeetles, with Bt crops delays a pest’s ability to evolve resistance to these insecticidal proteins.
“This is the first demonstrated example of a predator being able to delay the evolution of resistance in an insect pest to a Bt crop,” said Anthony Shelton

Mar 1, 2014

"While the importation and release of foreign natural enemies in classical biological control programs can be cost-effective, the released control agent can have unintended effects, such as the displacement of native natural enemies."
Evan Hoki, current graduate student in John Losey’s lab, is about to have a paper published in Biological Control titled “Comparing the consumptive and non-consumptive effects of a native and introduced lady beetle on pea aphids (Acyrthosiphon pisum)” Congratulations to Evan and the Losey lab!
 

Chikungunya fever: Will the virus spread to the US?

Feb 11, 2014

Some experts worry that it's only a matter of time before chikungunya fever spreads to the United States.
"We definitely should be concerned," said Laura Harrington, a professor of entomology at Cornell University who specializes in the spread of chikungunya and other tropical diseases.
The death rate from chikungunya is fairly low about 1 to 2 percent "but it does cause a lot of discomfort," Harrington told Live Science.

Biodiversity ensures plant-pollinator phenological synchrony against climate change.

Nov 1, 2013

Climate change has the potential to alter the phenological synchrony between interacting mutualists, such as plants and their pollinators. However, high levels of biodiversity might buffer the negative effects of species-specific phenological shifts and maintain synchrony at the community level, as predicted by the biodiversity insurance hypothesis. Here, we explore how biodiversity might enhance and stabilise phenological synchrony between a valuable crop, apple and its native pollinators.
