Partitioning boll weevil (Coleoptera: Curculionidae) mortality associated with high temperature: desiccation or thermal death?
Mortality of boll weevil, Anthonomus grandis Boheman, larvae and pupae resulting from exposure to high temperature can be partitioned into two categories, "desiccation" and thermal death. Larvae and pupae that die from thermal death turn a grey-brown color after death, do not move when pro...

description | Mortality of boll weevil, Anthonomus grandis Boheman, larvae and pupae resulting from exposure to high temperature can be partitioned into two categories, "desiccation" and thermal death. Larvae and pupae that die from thermal death turn a grey-brown color after death, do not move when probed or squeezed, and lose the resiliency of their integument. Those dying from "desiccation" will show the same characteristics but do not turn the grey-brown color; they generally retain the same color as live insects but have a very dried-out appearance. Thermal death is a function of exposure time and high temperatures. Low levels of thermal mortality appear in less than or equal to 3 h at 54.4 degree C. An estimated 99% mortality should result from a 2-h 18-min exposure at 60 degree C. |
