Technical Abstract: Landing rates (LR) for Aedes albopictus, Anopheles quadrimaculatus, Culex nigripalpus, Cx. quinquefasciatus, and Ochlerotatus triseriatus on a human subject were compared with collections of each species using a CDC light trap (CDC) baited with carbon dioxide during eight different observation times (Periods) in the diel (24 hour) period. On a catch-per-unit-effort basis, the capture efficiency ratio (LR/CDC) ranged from 3:1 (Cx. quinquefasciatus) to 36:1 (Oc.triseriatus) and favored the LR method in all cases. For Ae. albopictus, LR can be estimated from CDC capture responses in Periods 7 and 8. For An. quadrimaculatus, Cx. nigripalpus, and Cx. quinquefasciatus, LR can be estimated from CDC capture responses in, respectively, Periods 2 and 3, Periods 1 thru 4, and in Period 1. Bounds on error of estimated LR varies depending on the mosquito species but exceeds one order of magnitude for estimates of LR for Ae. albopictus, An. quadrimaculatus, and Cx. nigripalpus. Differences in mosquito activity indicated by each collection method suggest that LR and CDC methods may sample different components (or phases) of the mosquito population and/or simultaneously stimulate competitive response patterns in individual females.
