Abstract. Forty baits were tested in buckets to attract the red oak borer, 

 Enaphalodes rufulus (Haldeman). Only six beetles were caught. A low 

 beetle population and above normal rainfall may have reduced the catch. 

 However, many other cerambycids were trapped. 



Fermenting bait traps yield many species 

 of insects not commonly collected by other 

 methods (Champlain and Kirk 1926) and 

 have proved especially good for attracting 

 cerambycids (Champlain and Knull 1932). 

 However, the above authors did not report 

 capturing red oak borers, Enaphalodes rufulus 

 (Haldeman). This cerambycid is a serious pest 

 of living oak, Quercus spp., and causes mil- 

 lions of dollars worth of damage annually— 

 primarily in the form of degraded lumber 

 sawed from infested trees. Hay (1969) re- 

 ported that red oak borers emerge in odd- 

 numbered years. 



Previous bait trapping studies in even years, 

 not conducted in forest situations, and in 

 which only brown sugar or molasses and 

 water were used for bait, were unsuccessful 



in capturing red oak borers. Therefore, I 

 decided to test many kinds of substances for 

 baits in a forest during an odd-numbered 

 year (1979) to learn if red oak borers could 

 be attracted and trapped. 



MATERIALS AND METHODS 



The traps or buckets used were ten 14-liter 

 black plastic buckets, twenty 5-liter red 

 plastic buckets, and ten 4-liter sheet metal 

 buckets. 



Forty different baits were tested: honeys: 

 clover, cranberry, orange blossom, avocado, 

 eucalyptus, tupelo, alfalfa, buckwheat, linden, 



sourwood, and safflower; fresh fruits 



apples, cantaloup, watermelon, bananas, pears, 

 and peaches; canned juices: orange, pine- 

 apple, grapefruit, grape, apple and Hawaiian
