Las colonias de avispas sin reina dependen de ayudantes ocultas durante el caos

Cuando una avispa reina desaparece, su colonia tropical estalla en violentas luchas de poder. Una nueva investigación demuestra que algunas hembras evitan las peleas y, en su lugar, mantienen las tareas esenciales para evitar el colapso.

Investigadores del University College London examinaron colonias de avispas de papel tropicales, Polistes canadensis, en Panamá. Retiraron a las reinas de grupos establecidos y observaron una competencia agresiva inmediata entre las hembras por el dominio. El orden social normal se desmoronó rápidamente a medida que varias avispas competían por la posición principal.

A new field study shows that honey bees deprived of pollen become more aggressive and display signs of stress. Researchers simulated a pollen shortage over five weeks to examine the effects on bee behavior and health.

A hybrid population of honeybees in Southern California demonstrates natural resistance to Varroa mites, a major threat to bee colonies. Researchers at UC Riverside found these bees carry 68% fewer mites and require far less chemical treatment. The discovery, detailed in a new study, suggests early-life defenses in larvae may hold the key.

Buff-tailed bumblebees have demonstrated an ability to recognize rhythmic patterns, surprising scientists who thought it required a large brain. Researchers trained the insects to distinguish sequences of flashing lights and vibrations, akin to Morse code. The findings suggest even small-brained animals can process abstract rhythms.

Scientists observed a rare tropical katydid changing color from bright pink to green over 11 days in Panama. The transformation helps the insect mimic young rainforest leaves that start pink before maturing green. Researchers describe it as a survival strategy rather than a mutation.

Researchers at the University of East Anglia have found that Seychelles warblers with closer social ties share more similar gut microbes, particularly anaerobic types spread through direct contact. The study on Cousin Island suggests social interactions drive this microbial exchange. Similar effects likely occur among humans living together.
