title: The responses of Lucilia cuprina to odours from sheep, offal and bacterial cultures.
abstract: The responses of gravid female Lucilia cuprina to odours from sheep urine, faeces and gut mucus, and to odours from liver/sodium sulphide mixtures was tested using a bioassay which measured the movement and probing response of walking flies. The same bioassay was used to test the response to odours from cultures of bacteria isolated from liver/sodium sulphide and liver/water mixtures. A significant movement towards odours from faeces, gut mucus and urine was observed. Odours from cultures of the bacteria Proteus mirabilis, Dermatophilus congolensis and Serratia marcescens also elicited significant movement. A probing response was elicited by odours from gut mucus, fresh urine, liver/sodium sulphide mixtures and cultures of P.mirabilis, D.congolensis and gram-positive species. Odours from cultures of Pseudomonas aeruginosa, Enterobacter aerogenes and Citrobacter freundii did not elicit significant movement or probing. The movement and probing responses are discussed with reference to the possible uses of the substances tested as a bait for attracting L.cuprina.
