Rogue ovarioles and criteria for parity diagnosis in Culex tarsalis (Diptera: Culicidae) from Manitoba.
Rogue ovarioles were identified in laboratory-reared nulliparous and 1-parous Culex tarsalis Coquillett and in wild nulliparous C. tarsalis. Parity-diagnostic criteria were extrapolated from analysis of known nullipars and 1-pars. Diagnostic criteria were based, in part, on the number of ovarioles with no dilatation and a pedicel of greater than or equal to six adjacent cells. The high proportion of ovarioles lacking pedicels in known 1-pars and the small number of diagnostic ovarioles found in 2-pars support the findings of other researchers that ovulation destroys the pedicel and any previously formed dilatations.
