Characterization of Ag-NPs, (a) A transmission electron micrograph of Ag-NPs exhibits the size of the nanoparticles used in this study, and (b) The pore size distribution of Ag-NPs shows that the majority of nanoparticles are within a range from 20 to 25 nm. Fig. (c) The heat map presents the survival probabilities of different groups from 1 to 7 of female beetles, B. polychresta, throughout 30 days after injection with Ag-NPs at various doses of 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, and 0.07 mg/g body weight for each group, respectively. The red rectangle signifies the group of beetles treated with Ag-NPs, which was selected for further studies in comparison with the control group.
