IGP by <i>Harmonia axyridis</i> on <i>Episyrphus balteatus</i> in Petri dishes after 90 minutes.

Abstract

<p>Percentage of third instars of <i>Episyrphus balteatus</i> reared on an <i>ad libitum</i> or limited supply of aphids that were killed through IGP in Petri dishes after 90 minutes by third (A) and fourth (B) instars of <i>Harmonia axyridis</i> reared on various diets. Eph: <i>Ephestia kuehniella</i> eggs, Aph ad lib: <i>ad libitum</i> supply of <i>Acyrthosiphon pisum</i> aphids, Aph lim: limited supply of aphids, Pollen: moist honey bee pollen. The effect of larval diet of <i>H</i>. <i>axyridis</i> is indicated by lowercase letters (generalized linear model with Poisson error distribution and a log link function); within each panel, groups of bars followed by a different letter are significantly different. Error bars represent SE-values.</p
