A new study compares the genome sequence of bed bugs that live with humans and those that don't, finding that human-associated bed bugs recovered and increased in population size over time. The research suggests that humans may have inadvertently led to the emergence of modern bed bug pests.
A study analyzing locust temperature and behavior found the best time to apply biopesticides is when they are young, around 20 days after hatching. This timing ensures optimal conditions for effectiveness, as locusts have lower body temperatures in this stage.
Researchers at Tel Aviv University found that a specific type of bacteria, Weissella, becomes dominant in the gut microbiomes of locusts when they form swarms. This change may provide the bacteria with an evolutionary advantage, allowing them to spread and infect more locusts.
Locust swarms threaten food security in Asia, Africa, and Australia, costing billions of dollars in lost harvests. A new ASU-led project studies human behavior, market forces, and ecological systems to minimize locust outbreaks.
