Sap beetles bore into fruits about picking time, and are especially attracted to overripe fruits. They are more destructive on tomatoes where the beetles bore into the fruit through cracks or any damaged area on the tomato fruit. In table corn, sap beetles are particularly noticeable on ears where there has been bird damage or where corn borers or corn earworms have been feeding. In the corn field, if they are plentiful, they may enter by the silk on previously undamaged cobs. The sap beetles do not do the primary damage, but feed on the sap exuding from damaged tissue. They do not bite or sting.

URL: http://www.colostate.edu/Depts/Entomology/courses/en570/papers_1996/bishop.html

Several species within the genus Carpophilus are known pests on a wide variety of hosts. This paper reviews the elements involved in the attraction of these sepcies to their hosts, including host-related volatiles, aggregation pheromones , and the interaction between the two. Kairomonal activity between species is also discussed. This review is presented in context of the value of knowledge of attraction of sap beetles to possible control strategies for beetle populations.
