PURPOSE Information from unpublished reports, field, and greenhouse observations suggests that temperatures exceeding 29 deg C can cause reduced development and increased mortality of Megamelus scutellaris Berg waterhyacinth planthopper, a biological control agent released for the management of Eichhornia crassipes Mart. Solms. This document reports the results of an experiment conducted under greenhouse conditions designed to gauge temperature impacts to M. scutellaris survival and reproduction under fluctuating temperatures regimes.
