“…After 24 h, the number of eggs laid in treated and control bowls were counted under a stereomicroscope (Olympus, Japan). The effective attractiveness (EA %) for each oviposition concentration was calculated [24] and the oviposition active index (OAI) was assessed [25].…”

Mosquitoes are key vectors of malaria, dengue, yellow fever, chikungunya, West Nile, Japanese encephalitis, lymphatic filariasis, Zika virus and St. Louis encephalitis virus. Eco-friendly control tools of Culicidae vectors are a priority. Green nanotechnologies may help to boost the effectiveness of mosquito vector control. We proposed a facile fabrication of poly-disperse and stable silver nanoparticles (AgNPs) using the Aganosma cymosa leaf extract. Nanoparticles were characterized by UV-visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction analysis, atomic force microscopy, scanning electron microscopy and transmission electron microscopy. Nanoparticles showed high toxicity on eggs and larvae of Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus. LC 50 values were 12.45, 13.58 and 14.79 lg/mL, respectively. No egg hatchability was noted post-treatment with 40, 50 and 60 lg/mL, respectively. Nanoparticles were found safer to non-target mosquito predators Anisops bouvieri, Diplonychus indicus and Gambusia affinis, LC 50 values ranged from 673.36 to 2247.43 lg/mL. Notably, AgNPs showed high oviposition attractiveness towards the three mosquito species. Overall, the oviposition attractiveness of the A. cymosa extract coupled with the ovicidal action of AgNPs can help to develop ''lure and kill'' tools to be used at mosquito breeding sites.

“…where N t =total number of eggs in the test solution, and Ns= total number of eggs in the control solution (Kramer and Mulla 1979). The oviposition active indices of +0.3 and above are considered as attractants, while those with −0.3 and below are considered as repellents (Govindarajan et al 2011).…”

In mosquito control programs, insecticides of botanical origin have the potential to eliminate eggs, larvae, and adults. So, the larvicidal, ovicidal, and oviposition-deterrent activities of petroleum ether and ethyl acetate extracts of the leaves of Eugenia jambolana, Solidago canadensis, Euodia ridleyi, and Spilanthes mauritiana were assayed against the three vector mosquito species, namely Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus. The larval bioassay was conducted following the World Health Organization method. The maximum larval mortality was found with ethyl acetate extract of S. mauritiana against the larvae of A. stephensi, A. aegypti, and C. quinquefasciatus with LC 50 values of 11.51, 28.1, 14.10 ppm, respectively. The mean percent hatchability of the ovicidal activity was observed at 48-h post-treatment. The percent hatchability was found to be inversely proportional to the concentration of the extract and directly proportional to the number of eggs. The flower head extract of S. mauritiana gave 100 % mortality followed by E. ridleyi, S. canadensis, and E. jambolana against the eggs of the three mosquito vectors. For oviposition-deterrent effect, out of the five concentrations tested (20, 40, 60, 80, and 100 ppm), the concentration of 100 ppm showed a significant egg laying-deterrent capacity. The oviposition activity index value of E. jambolana, E. ridleyi, S. canadensis, and S. mauritiana against A. aegypti, A. stephensi, C. quinquefasciatus at 100 ppm were −0.71, −0.71, −0.90, −0.93, −0.85, −0.91, −1, −1, −0.71, −0.85, −1, and −1, respectively. These results suggest that the leaf/flower extracts of certain local plants have the potential to be developed as possible eco-friendly means for the control of mosquitoes.

The origin of stimulants in mosquito breeding sites and their mode of action towards gravid females are not fully understood, though it has been suggestively linked to microbial activity (Ikeshoji et al, 1975;Kramer and Mulla, 1979;Benzon and Apperson, 1988;Takken and Knols, 1999;Gimnig et al, 2001).…”

Abstract. Laboratory studies were carried out to investigate the role of larval habitatderived microorganisms in the production of semiochemicals for oviposition site selection by Anopheles gambiae Giles sensu stricto mosquitoes. Dual-choice bioassays with gravid females were conducted in standard mosquito cages. Field-collected or laboratory-reared mosquitoes, individually or in groups, were offered a choice between unmodified (water or soil from a natural breeding site) or modified substrates (filtered water, autoclaved soil or sterile media to which bacterial suspensions had been added). Egg counts were used to assess oviposition preferences.Mosquitoes preferred to oviposit on unmodified substrates from natural larval habitats containing live microorganisms rather than on sterilized ones. Variable responses were observed when sterile substrates were inoculated with bacteria isolated from water and soil from natural habitats.We conclude that microbial populations in breeding sites produce volatiles that serve as semiochemicals for gravid An. gambiae. These signals, in conjunction with other (non-olfactory) chemical and physical cues, may be used by the female to assess the suitability of potential larval habitats in order to maximize the fitness of her offspring.Key words: oviposition site selection, soil microbiota, semiochemicals, Anopheles gambiae Résumé. Des études de laboratoire ont été conduites afin de déterminer le rô le de substances chimiques attractives de microorganismes présents dans les sites larvaires dans la préférence de ponte des femelles gravides d'Anopheles gambiae s.s. pour ces sites. Un test biologique à double choix a été mis en place dans des cages à moustiques standards contenant des femelles gravides. Un choix entre substrat naturel (eau et sol non modifiés provenant des sites larvaires naturels) et substrat modifié (eau filtrée, sol stérilisé, ajout de suspensions bactériennes) est offert individuellement ou en groupe aux femelles collectées sur le terrain ou élevées en laboratoire. Le nombre d'oeufs pondus dans chaque substrat a été utilisé comme critère pour évaluer la préférence des femelles gravides pour un substrat particulier. Les femelles ont préféré pondre dans le substrat naturel contenant des microorganismes vivants plutô t que dans le substrat stérile. Des réponses variables ont été observées lorsque des bactéries provenant des sites larvaires naturels ont été inoculées dans le substrat stérile. Nous concluons que la population microbienne, présente dans les site larvaires, produit des substances chimiques odorantes attirant les femelles gravides d'Anopheles gambiae s.s. Ces signaux, associés à d'autres substances non odorantes et à des facteurs physiques, peuvent être utilisés par les femelles pour évaluer le potentiel d'un site larvaire, en vue du développement optimal de leur progéniture.
