Parameters observed to determine the optimum incubation temperature.

<p>(A) Mean OB production (OBs/larva) and (B) Mean time to death (hours post-infection) of L₅ <i>H</i>. <i>armigera</i> larvae after inoculation with a LC₉₅ concentration of HearSP1B:LB6 OBs and incubated at 23, 26 and 30°C until death. Values followed by identical letters did not differ significantly (OB production: ANOVA, Tukey test, P>0.05; Mean time to death: Weibull analysis, P<0.05). Vertical bars indicate the standard error.
