The use of a Blue Hubbard squash trap crop and a polyculture of cucumbers and tomatoes for the control of cucumber beetles (Acalymma vittatum F.) was studied in middle Michigan in 2006. The trap crop had the greater effect in preventing beetle presence and injury to cucumber when compared to a cucumber monoculture. The polyculture of cucumber and tomato added to the trap crop treatment provided no to little additional protection. Other factors considered were distance from the trap crop and the potential for cucurbitacin applications to the trap crop to enhance the trap crop effect. Potential applications of our findings to organic and conventional production systems are discussed.
