Other claims from this paper (16)

Observation Oviposition and larval development succeeded on Ipomoea tenuirostris.
Observation Oviposition and larval development succeeded on Ipomoea cairica.
Observation No oviposition occurred on the other three wild Ipomoea species.
Observation Larvae did not feed on Ipomoea hochstetteri.
Observation Larvae did not feed on Ipomoea indica.
Observation Larval survival was extremely low on Ipomoea purpurea.
Association Sweet potato was preferred for oviposition over I. tenuirostris and I. cairica.
Association Larval survival was better on sweet potato than on the two wild species.
Association Pupal size was better on sweet potato than on the two wild species.
Mechanism Larger pupae from sweet potato produced more fecund female butterflies.
Observation Wild butterfly populations were abundant on I. tenuirostris.
Observation Wild butterfly populations were absent on I. cairica.
Association Females tended to prefer I. tenuirostris for oviposition over I. cairica.
Association Larval performance did not differ significantly between I. tenuirostris and I. cairica.
Association Wild Ipomoea butterfly populations were judged too sparse to affect sweet potato populations.
Mechanism Wild populations may serve as reservoirs after butterfly population bottlenecks on sweet potato.
