Figure 4. (A) Mortality of neonate Leptinotarsa decemlineata larvae exposed to Tca for 48 h. Each point represents the mean mortality (± SEM) in three separate assays of 12 larvae. (B) Growth of second instar L. decemlineata larvae exposed to Tca for 72 h. Each point represents the mean weight gain (± SEM) of larvae fed Tca relative to control larvae. For each point, 12 larvae were assayed on two separate occasions. At the highest concentrations, mortality was observed (ca. 50% at the highest dose).
