Our assay demonstrated that when
only 50% of a bed bug population was directly exposed to fungus,
total mortality exceeded 95%. Other studies have demonstrated
autodissemination of conidia (Scholte et al., 2004) and potential
for disease cycling following biopesticide spray applications
(Arthurs and Thomas, 1999; Thomas et al., 1995). Since bed bugs
are highly gregarious with all life stages aggregating in confined
harborages with humid microclimates (Usinger, 1966), horizontal
transmission could greatly increase the impact of fungal treatments
relative to conventional chemicals.
