“…No detectable toxicity effects were observed on O. melastigma individuals exposed to the AgNP-contaminated aquatic environment (post-treatment observation period: 10 days; data not shown). In agreement with our data, previous studies testing other aquatic species, including Gambusia affinis [28,126];), Hoplobatrachus tigerinus [84], Poecilia reticulata [85], Aplocheilus lineatus [127], Carassius auratus (Linneaus) [29], Xenontodon cancila [27], Ctenopharyngodon idella, Cyprinus carpio [30], Oreochromis niloticus niloticus [25,46], Betta splendens, Pseudotropheus tropheops tropheops, Osphronemus goramy Lacépède, and Pterophyllum scalare [45], showed good predatory ability on mosquito larvae under similar testing conditions. Recently, Chobua et al [34] studied G. affinis and C. auratus as control agents of A. gambiae.…”
