BMSB Dispersal



BMSB nymphs can move among host plants within a planting or among different host plants on a farm. This sub-objective will elucidate the spatial scale of their movement and host preferences of nymphs.



A summer student is watching 3rd and 5th instar BMSB to record their walking capacity across different times of day on this grass field in a USDA-ARS research farm in West Virginia (photo credit: Doo-Hyung Lee).


This is one of the 3rd instars we were watching and recording. This insect is small and well camouflaged; which means we often lose this insect while tracking (photo credit: Doo-Hyung Lee).


A large-scale mark-release-recapure study was set up in an organic farm (Redbud Farm) in WV to measure nymphal dispersal capacity using the newly-identified BMSB olfactory attractant (photo credit: Doo-Hyung Lee).

Marked bugs with various colors (although only white shown here) were released in the experiment to code bugs between experimental plots and dates (photo credit: Doo-Hyung Lee).

BMSB nymphs were marked with different colors and then relesed from center plants bi-weekly throughout the summer. After 1, 3, and 5 days afer each release, plants were observed for marked nymphs. BMSB nymphs were able to disperse from the center plants and appear to make a host plant choice for the best resources (Bridgeton, NJ).
