Two new studies find even more benefits to tolerating scale insects on urban trees, boosting the abundance of a variety of spiders and attracting predator insects that serve as natural enemies of other pests in both trees and nearby plants.
With ash trees decimated by the emerald ash borer, where do other insects that depend on ash go? A new study shows landscape managers that choosing the right replacements for ash is critical for such ash-reliant native insects.
Studies have shown host plants for fall armyworm (Spodoptera frugiperda) potentially numbering in the hundreds, but a group of researchers suggests differentiating between plants that the insect prefers for its full life cycle versus those that are more likely to be secondary food sources.
A new study finds endangered Miami blue butterfly larvae survive in greater numbers when protected by Florida carpenter ants, which fend off predators in exchange for the caterpillars' sugary secretions.
A new review looks at innate immunity and superorganism-level social immunity as defenses against immune challenge by viruses in eusocial ants, bees, and wasps.
