First it’s mammal bad breath. Then it’s babies pestering for piggyback rides. A near-death experience is tough on pea aphids. Now Gish and Moshe Inbar, both at the University of Haifa in Israel, ...

The pea aphid is one of the weirdest and most versatile creatures around. It can reproduce sexually or asexually, can breed winged or unwinged babies, and is also a symbiote. This week, its genome has ...

Induced prey defenses can be costly. These costs have the potential to reduce prey survival or reproduction and, therefore, prey population growth. I estimated the potential for predators to suppress ...

Pea aphids -- a serious agricultural pest -- have the ability to see and avoid a common, aphid-killing bacteria on plant leaves, according to a new study. Pea aphids -- a serious agricultural pest -- ...

Evolution is unfolding in real time within many natural animal populations and researchers are now observing how this influences biodiversity in the field. In a newly published study in Molecular ...

To determine the genes that regulate nepetalactone production in aphids, the researchers "harvested" legs from aphids, because the pheromone nepetalactone is produced exclusively in the hind legs of ...

The pea aphid U-type symbiont (PAUS) was investigated to characterize its microbiological properties. Fluorescence in situ hybridization (FISH) and electron microscopy revealed that PAUS was a ...

The paper B. Li et al., “A large genomic insertion containing a duplicated follistatin gene is linked to the pea aphid male wing dimorphism,” eLife, 9:e50608, 2020. The sap-sucking pea aphid ...

Researchers shed light on the important role that microbial genes, like those from viruses, can play in insect and animal evolution. Many of an organism's traits are influenced by cues from the ...

Aphid numbers are average to above average across the inland Pacific Northwest, a university researcher says. “While there is definitely more activity for most aphid species compared to last year, it ...

Many of an organism's traits are influenced by cues from the organism's environment. These features are known as phenotypically plastic traits and are important in allowing an organism to cope with ...
