Microbiome analysis of gut of Harmonia axyridis. (a) Micrograph of bacteria in the lumen of the hindgut of a female H. axyridis. b: bacteria; hc: hemocoel, hg: hindgut; mu: muscle layer; mp: Malpighian tubules. (b) Heatmap showing relative proportion of bacteria summarized at genus level for male and female samples (gut tissue and residual body tissue) for adult beetles fed on aphid and grape diets. ap: aphid diet; bod: residual body tissue; M: males; F: females; gr: grape diet. Bacteria highlighted in red are presumed to produce MPs
