Statistical analyses were performed with the R software, version 3.2.3 and Systat, version 13. The binomial response variable 'survival' (i.e., probability or proportion of survival) was analyzed with Cox's proportional hazard [54] test ('coxph' function) from the 'survival' package in R. We used **data** for animals that were dead at day 3, 4, and 5 and censored the **data** for individual insects that were alive on day 5. We used the function survfit to model expected survival for all groups, with 95% confidence intervals. These models were used for graphical representation of survival within each treatment group.
