Abstract
A bioassay of the attractive effect of mouse urine on the habu, Trimeresurus flavoviridis, was carried out by trapping in the field and by nighttime observations of foraging behavior in an outdoor pen. No habus and nine Dinodon semicarinatum, a colubrid snake, were captured by traps baited with mouse urine during a period of about six months, whereas 12 habus and nine D. semicarinatum were captured by control traps baited with a live mouse. Nighttime observations of foraging behavior of habus suggested that mouse urine attracts a habu, but is not attractive enough to induce it to enter a trap.
