The T-STAR Hawai'i
Coqui Frog Invasive Species Project is investigating the efficacy
of vapor heat on coqui frog eggs and which plants can tolerate
the heat treatment. Treatment with hot, humid air
(45°C [113°F], > 90% relative humidity) for 15
minutes is lethal to frogs and eggs.
Testing for thermal damage was conducted on a variety of
ornamental plants. Orchids and bromeliads were more
heat-sensitive than other plants tested.
To find out more about the results of the tests, see the
of Plants Following a Foliar Application of 25% Citric Acid report.
