Effect of laboratory heat stress on mortality and web mass of the common house spider, Parasteatoda tepidariorum (Koch 1841) (Araneae: Theridiidae) [PDF]

open access: yes, 2020
We determined the effects of chronic heat stress on web construction of Parasteatoda tepidariorum (Araneae: Theridiidae) by measuring the survival and web mass of specimens after a 48-h period within a temperature chamber at 21, 30, 35, 40, or 50°C.
