Fig. 1.

Species richness and diversity indices based on the Chao1 and Shannon indices. a Species richness of Z. cucurbitae samples reared on bran-diet, irradiated (IR_BR) and non-irradiated (NIR_BR), and samples reared on sweet gourd, irradiated (IR_SG) and non-irradiated (NIR_SG). b Species richness of female (F) and male (M) samples reared on bran-diet (BR) and sweet gourd (SG) before (NIR) and after irradiation (IR). c Diversity index of female (F) and male (M) samples reared on bran-diet (BR) and sweet gourd (SG) before (NIR) and after irradiation (IR). Boxes denote the interquartile range, the line within the box is the median, and whiskers extend to the most extreme values
