Table 5 Estimated values of the lower temperature threshold (tmin), optimal temperature (topt), and upper temperature threshold (tmax) for different immature stages of the common green lacewing, Chrysoperla carnea, using Lactin-2 nonlinear model

From: Modeling of the effect of temperature on developmental rate of common green lacewing, Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae)
