Table 1 Oviposition preferences in multiple-choice assays. Random-intercept negative-binomial regression table of the effect of different oviposition substrates on the cumulative number of eggs oviposited per filter paper disc in 6-choice oviposition assays. Table also presents means (±SE) of egg numbers oviposited per filter paper disc for each substrate type. Test materials included larval rearing media of different types and stages including: fresh rabbit feces (RF), fresh larval food (LF), rearing medium containing frass of 2nd-3rd instar larvae (2nd/3rd), rearing medium containing frass of 4th instar larvae and pupae (4th/pupa), frass of rearing cups from which all larvae had eclosed (expired) and a negative (water) control. Rearing media of 2nd/3rd and 4th/pupa (bolded) induced highest oviposition response
