First Record of Clonostachys rosea as an Entomopathogenic Fungus of the Cephus fumipennis (Hymenoptera: Cephidae) in China

mycolabadmin

Scientists in China discovered a fungus called Clonostachys rosea that naturally kills wheat stem sawfly larvae, a major pest damaging wheat crops. The fungus was isolated from infected larvae and tested for effectiveness against the pest. Laboratory tests showed the fungus can kill sawfly larvae at different concentrations, with the fastest effect at higher spore levels. This discovery offers a natural and environmentally friendly alternative to chemical pesticides for protecting wheat crops.

Age-related mushroom body expansion in male sweat bees and bumble bees

Researchers studied how male bee brains change as they mature using microscopy to measure brain structures. They found that mushroom bodies, regions associated with learning and memory, expanded significantly in maturing males of two bee species even when kept in isolation without normal experiences. This suggests that brains naturally prepare for mating behaviors through development rather than requiring experience, and shows that male insects undergo similar brain changes as females.
