tree space (25%), the tree trunk (17%), or grass 

 beneath the canopy (4%) (Table 1). Among 

 curcuhos that crawled, significantly more (88%) 

 crawled toward the tree trunk than toward all 

 other directions combined (12%) (Table 1). 



Of the 104 plum curculios observed beneath 

 the plum tree, 39 (38%) left the framed cloth by 

 flight and 19 (18%) by crawling. The remain- 

 der moved to hide beneath foliage on the cloth 

 (13%) or rested in place (31%). Among those 

 that flew, significantly more flew toward the tree 

 canopy above (36%) or toward inter-tree space 

 (38%) than toward the pyramid trap at the tree 



trunk (15%), the pyramid trap at the canopy 

 edge (3%) or grass beneath the canopy (8%) 

 (Table 2). Among curculios that crawled, sig- 

 nificantly more (74%) crawled toward the pyra- 

 mid trap at the tree trunk than toward the pyra- 

 mid trap at the canopy edge (10%) or toward 

 other directions (16%) (Table 2). 



Temperatures taken beneath each tree at 

 the time of observed curculio movement indi- 

 cated that no flight occurred at temperatures 

 of 67°F or less. Also, there was a significant 

 positive correlation between temperature and 

 proportion of total observed curculios that flew.
