“…Marten reported single-copepod predation rates of 90% on first instar mosquito larvae after 24 h [27] . A low predation rate of copepods on late instar mosquito larvae has been reported by previous authors [27][28][29][30] . Predation dropped considerably for 4 d and older larvae, which is consistent with previous observations for Mesocyclops longisetus [31] .…”

“…But the size of the larva also shows disturbance to M. aspericornis for predation even at higher concentration and no predation was observed and less predatory effect in late instar of third compared to the early instars of first and second. Marten reported larger copepods, including many species of Mesocyclops, typically kill 95%-100% of the Aedes larvae in a container and cyclopoids reduced the numbers of third and fourth instars even more than they reduced the number of positive containers [27] .…”

“…Our results are in agreement with previous evidences on other species. Indeed, adult copepods belonging to other species have been found effective to control young larval instars of different mosquitoes, including the arbovirus vectors Aedes albopictus and A. aegypti, while little predation rates have been observed against late instar larvae ( Kay et al 1992;Schreiber et al 1993;Marten et al 1994;Murugan et al 2015a, b). Post-treatment with spongeweed-synthesized AgNP, the predatory efficiency of a single M. aspericornis per day was comparable to standard laboratory conditions, i.e., 8.3, 6.6, 1.9, and 1.1 larvae (larva I, II, III, and IV, respectively) (Table 4).…”

Mosquitoes act as vectors of devastating pathogens and parasites, representing a key threat for millions of humans and animals worldwide. The control of mosquito-borne diseases is facing a number of crucial challenges, including the emergence of artemisinin and chloroquine resistance in Plasmodium parasites, as well as the presence of mosquito vectors resistant to synthetic and microbial pesticides. Therefore, eco-friendly tools are urgently required. Here, a synergic approach relying to nanotechnologies and biological control strategies is proposed. The marine environment is an outstanding reservoir of bioactive natural products, which have many applications against pests, parasites, and pathogens. We proposed a novel method of seaweed-mediated synthesis of silver nanoparticles (AgNP) using the spongeweed Codium tomentosum, acting as a reducing and capping agent. AgNP were characterized by UV-Vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). In mosquitocidal assays, the 50 % lethal concentration (LC 50 ) of C. tomentosum extract against Anopheles stephensi ranged from 255.1 (larva I) to 487.1 ppm (pupa). LC 50 of C. tomentosum-synthesized AgNP ranged from 18.1 (larva I) to 40.7 ppm (pupa). In laboratory, the predation efficiency of Mesocyclops aspericornis copepods against A. stephensi larvae was 81, 65, 17, and 9 % (I, II, III, and IV instar, respectively). In AgNP contaminated environment, predation was not affected; 83, 66, 19, and 11 % (I, II, III, and IV). The anti-plasmodial activity of C. tomentosum extract and spongeweed-synthesized AgNP was evaluated against CQ-resistant (CQ-r) and CQ-sensitive (CQ-s) strains of Plasmodium falciparum. Fifty percent inhibitory concentration (IC 50 ) of C. tomentosum were 51.34 μg/ml (CQ-s) and 65.17 μg/ml (CQ-r); C. tomentosum-synthesized AgNP achieved IC 50 of 72.45 μg/ml (CQ-s) and 76.08 μg/ml (CQ-r). Furthermore, low doses of the AgNP inhibited the growth of Bacillus subtilis, Klebsiella pneumoniae, and Salmonella typhi, using the agar disk diffusion and minimum inhibitory concentration protocol. Overall, C. tomentosum metabolites and spongeweed-synthesized AgNP may be potential candidates to develop novel and effective tools in the fight against Plasmodium parasites and their mosquito vectors. The employ of ultra-low doses of nanomosquitocides in synergy with cyclopoid crustaceans seems a promising green route for effective mosquito control programs.

“…Although cyclopoids offer possibilities for controlling many different kinds of mosquito larvae, [8][9][10] most of their use to date has been directed toward container-breeding Aedes. Various species of Mesocyclops, Macrocyclops, Megacyclops, and Acanthocyclops have been field tested in a variety of Aedes-breeding habitats in the Pacific, the Americas, and Asia, including wells, water storage containers (e.g., tanks, 200-liter drums, and ceramic jars), discarded tires, and land crab (Cardisoma carnifex) burrows.…”

“…albopictus (Skuse) have been eradicated by introducing cyclopoids into tires in New Orleans, Louisiana, 15 where Mesocyclops has become an operational part of municipal mosquito control. 10 In the tropics, where dengue is an ongoing problem, Mesocyclops have generally proved effective, reducing Ae. aegypti production by 95-100%.…”

Abstract. In northern Vietnam, copepods of the genus Mesocyclops were used for biological control of Aedes aegypti, the principal vector of dengue viruses, by inoculation into wells, large cement tanks, ceramic jars, and other domestic containers that served as Ae. aegypti breeding sites. The use of Mesocyclops was complemented by community participation with respect to recycling to eliminate unused and discarded containers that collected rainwater and provided Ae. aegypti breeding sites that could not be treated effectively with Mesocyclops. Aedes aegypti disappeared from 400 houses of the treated village in August 1994 and has not reappeared, a result of particular significance, because there are virtually no other recorded instances of eradicating this mosquito anywhere in the world during the past 25 years, and certainly not with community-based approaches. When used in combination with community recycling, Mesocyclops is an easy and inexpensive method of Ae. aegypti control that should be effective for many communities in Vietnam and elsewhere.Dengue and dengue hemorrhagic fever (DHF) are mosquito-borne viral diseases known to occur in more than 100 countries, placing two-fifths of the world's population at risk.
