Blacklight (BL) traps baited with virgin female tobacco hornworms, Manduca sexta(L.), collect appreciably more males than unbaited traps because of the attraction to the pheromone produced by the females (Hoffman et al. 1966). A test is planned in which baited traps will be used in an attempt to suppress populations of hornworms over an entire area. However, a necessary prerequisite for such a test is a container that will hold the female moths at the trap. Also, we wished to keep them alive as long as possible, since they produce the pheromone for at least the 1st 5 days of life (Cantelo and Smith 1971), and we would benefit greatly if they would not have to be replaced often. Ideally, such a container should be designed to permit them to feed and thus live their full life expectancy; however, this moth feeds only while it hovers in flight and, because of its 4-in.-long proboscis, must be substantially above the feeding site. Since it was not practicable to construct and install containers of sufficient size to permit feeding activity at each of the 250 traps that are to be used in the suppression experiment, we designed a cage that would permit them to live as long as possible without feeding.
