Biologists have made a detailed analysis of specific aspects of the genome of the important plant pest, the pea aphid. A special issue of Insect Molecular Biology reports the detailed analyses of ...

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, ...

Having the right bacteria can be a lifesaver for an aphid. Having the wrong bacteria, or no bacteria at all, could be a recipe for becoming wasp fodder. Pea aphids vary in their resistance to ...

Coral Gables, FL (February 23, 2010)—For the first time, scientists have sequenced the entire genome of the pea aphid, a notorious horticultural and agricultural pest. The findings reveal the extent ...

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 ...

Pea aphids, expert survivors of the insect world, appear to lack major biological defenses, according to the first genetic analysis of their immune system. "It's surprising," says Emory biologist ...

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 ...

Using an optimized CRISPR/Cas9 workflow and DIPA-CRISPR, researchers identified Laccase2 as essential for hardening and darkening overwintering eggs in pea aphids. Knockout mutations left eggs fragile ...

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 ...

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 ...

For pea aphids, the ability to go forth and multiply can depend on a single gene, according to new research. An overheated aphid with a mutation in that gene can't reproduce. The gene isn't even in ...
