Black Soldier Flies Show Potential as Source of Antimicrobial Compounds

Black soldier flies (Hermetia illucens) live in decomposing, bacteria-rich organic material, which demands a potent immune system. A study by researchers in Peru and France has isolated four peptides from larvae of the black soldier fly that display antibacterial properties, suggesting further "bioprospecting" research into black soldier flies could one day generate useful new antibacterial compounds for medical use.

Wildflower Strips Bring Farmers Extra Money While Helping Native Bees

Planting strips of wildflowers next to crops is a boon for native bees, but few farms adopt the practice. A new study, however, shows farmers can turn an immediate profit by selling wildflower seeds retail, while the long-term benefits of increased pollination and crop yields materialize over time.

Hetaerina americana damselfly

As a Watershed is Urbanized, Damselflies Show Declines

A study along a river in Central Mexico finds Hetaerina americana damselflies in reduced numbers after a decline in vegetation the addition of wastewater outlets. Researchers say the decline illustrates the impact of human land use on natural ecosystems.

Trichopria anastrephae

New Study Aims to Protect Parasitoids of Spotted-Wing Drosophila

Use of an insecticide can be counterproductive if it also harms natural enemies of a target pest. A new study puts several insecticides currently in use to manage spotted-wing drosophila to the test to see how they do or don't affect parasitoids of the invasive fruit fly.

No Buzz, No Problem: Study Shows How Honey Bees Pollinate Blueberries

Honey bees are incapable of buzz pollination, but they can (and do) perform pollination duties in highbush blueberry. A new study shows that, while honey bees rarely collect blueberry pollen in the pollen baskets on their hind legs, they frequently contact it with other body parts and transfer it to other flowers.

Epicauta chinensis blister beetle

What Puts the Blister Into Blister Beetles?

By John P. Roche Blister beetles produce cantharidin, a 10-carbon isoprenoid molecule that is highly bitter and is toxic to most animals. Because cantharidin is so bitter, it discourages predators, […]
