The distribution of covert microbial natural enemies of a globally invasive crop pest, fall armyworm, in Africa: Enemy release and spillover events. [PDF]

J Anim Ecol, 2022
The infection of the invasive fall armyworm, with a natural enemy from its native range and novel pathogens from its new range, has important consequences for understanding the population ecology of invasive species and virus–insect interactions. The authors show that temporal and geographic factors are also important in understanding the distribution ...

Hitching a Ride: Examining the Ability of a Specialist Baculovirus to Translocate through Its Insect Host’s Food Plant [PDF]

Pathogens, 2021
Plant vascular systems can translocate the entomopathogen Bacillus thuringiensis from the soil into plant tissues. However, whether other soil dwelling entomopathogens utilize plant vascular tissue for movement has not yet been fully explored.
