The attraction behaviour of four synanthropic species of Blattaria (Blattella germanica, Supella longipalpa, Blatta orientalis and Periplaneta americana) was investigated. Methanol faecal extracts always showed a higher intraspecific attractivity than aqueous extracts in “Y” olfactometer bioassays. A gel with resistance to dehydration was prepared, and then methanol faecal extracts were added. Arena bioassays showed that the new gel containing faecal extracts was always more attractive than commercial gel formulations.

Abstract
The attraction behaviour of four synanthropic species of Blattaria (Blattella germanica, Supella longipalpa, Blatta orientalis and Periplaneta americana) was investigated. Methanol faecal extracts always showed a higher intraspecific attractivity than aqueous extracts in “Y” olfactometer bioassays. A gel with resistance to dehydration was prepared, and then methanol faecal extracts were added. Arena bioassays showed that the new gel containing faecal extracts was always more attractive than commercial gel formulations.
