[DATASET] Testing <i>Regiella insecticola </i>effects on chemical and entomopathogen tolerance across two aphid species

However, this will depend on <i>Regiella</i> being integrated into current control strategies. We therefore investigated the effects of a <i>Regiella</i> strain on chemical and entomopathogen tolerance across two species, <i>Myzus</i> <i>persicae </i>(Sulzer) (Hemiptera: Aphididae) and <i>Rhopalosiphum</i> <i>padi </i>(L.) (Hemiptera: Aphididae), focusing on an uninfected and transinfected strain of <i>R. padi </i>with <i>Regiella</i>, and a naturally infected strain of <i>M. persicae</i> coupled with its cured strain.

We consider three insecticides registered in Australia for aphid control – pirimicarb (carbamate), dimethoate (organophosphate) and imidacloprid (neonicotinoid) – along with effects of the generalist entomopathogen, <i>Beauveria bassiana</i>. There was no effect of <i>Regiella</i> on tolerance to the three pesticides in either species. Species differences in response to the entomopathogen were found, with <i>M.</i> <i>persicae</i> having a sharper increase in mortality at day 14 of exposure, and <i>R. padi</i> showing a more gradual response.
