Comparing the genomes of modern pathogens with those of cryopreserved strains from several decades ago shed light on the evolution of coffee wilt disease outbreaks in Africa.
A population explosion that began late last year has yet to abate. Meanwhile, researchers are exploring novel approaches to combat the nonnative species.
The use of pesticides has decreased in the US by more than 40 percent since 1992, but the emergence of more-potent chemicals means that they are far more damaging to many species.
Whiteflies overcome a toxin in plants they eat through the use of the plant’s own genetic protection, likely ferried from plant to insect millions of years ago by a virus.
As global temperatures rise and winters shorten, caterpillars of the corn borer moth are emerging earlier in parts of the US thanks to changes in two genes, researchers find.
A decade-long study tallies the numbers of pest-eating, flower-pollinating hoverflies that travel to the UK every year, and illustrates their important ecological roles in southern Britain.
