Similarly, Thakur and Kocher (2018) also observed the influence of mixed crustaceans on mortality of developmental stages of Ae. aegypti and significant decline in % survival of pupae and emergence of the adults.…”

Aedes aegypti L., is a serious global threat to human health as a vector for spreading several deadly diseases. Plant extracts provide an efficient and ecofriendly alternate to manage this menace. The sublethal concentrations i.e. 50 and 60 ppm of nanoemulsified eucalyptus oil evaluated against 4th instar (L4) Ae. aegypti larvae resulted in 16.67± 1.67 and 8.33± 1.67% larval survival followed by a significant delay in duration of various developmental stages and decrease in % pupal formation and their survival. Thus, decline in % emergence along with significant reduced body size and longevity were observed in comparison to control and vehicle-control emerged adults. These results reveal the potential of such nanoemulsified oils to be used as phytochemical agents for the sustainable control of Ae. aegypti.

“…intra or interspecific mosquito competitors) is linked to increased mortality of the mosquito species of concern, delayed maturity, reduced adult size and reduced adult longevity (Agnew et al, 2002;Braks et al, 2004;Reiskind & Lounibos, 2009;Renshaw et al, 1993;Teng & Apperson, 2000). D. magna were found to be effective competitors than M. aspericornis which being larger in size resulted in delaying the overall developmental period of Aedes larvae efficiently (Thakur & Kocher, 2020). Yoshika et al (2012) had also demonstrated that intraspecific competition for food among larvae of Ae.…”

Background Dengue and chikungunya are two mosquito-borne viruses transmitted by the mosquito, Aedes aegypti, and are responsible for great public health concerns in India. The present study tested the effect of Daphnia magna, a freshwater cladoceran, on the growth and pupation of Ae. aegypti larvae. Results Ae. aegypti third instar larvae and adult, D. magna, were introduced in the ratios 1:1, 1:2 and 1:3 into beakers and placed in an illuminated BOD incubator at a temperature of 26 ± 1 °C. The delay in the duration of larval stages (the time taken from third instar stage until their emergence as adults) was measured. The emergence of adults was delayed for 3–4 days in the treatments where the ratio of D. magna was thrice the number of Ae. aegypti larvae. The L3 larval stage was found to be more prone to mortality than later instars, with 51.66% larval mortality. The sex ratio of males to females emerged was only 5:5 in the 1:3 ratio. Body size of both males and females was significantly reduced in all the treatment sets in the ratios: 1:1, 1:2 and 1:3 when compared with the control set. Longevity of adult was also reduced from 8–15 to 4–7 days in the case of males, and in the case of females it was reduced from 14–25 to 5–9 days in the treatment set when Daphnia was introduced thrice the number of Aedes larvae. Conclusions Our study provides evidence that D. magna affects the growth and pupation of Aedes larvae and consequentially the life history parameters that affect the fitness of the population.

Objective: To determine the diversity of microbiota associated with different breeding habitats of dengue vector mosquitoes Aedes (Ae.) aegypti. and Ae. albopictus and to identify any parasitic, epibiont, pathogenic, competitive or predatory species. Methods: Sampling was performed from a variety of breeding habitats using dipping, pipetting and siphoning techniques. Microbiota in water samples were preserved using Rose Bengal solution and Lugol's iodine, and were identified. Live samples of microbiota were kept under laboratory conditions to observe any pathogenic or parasitic microbiota interacting with larvae. Results: A total of eleven microbiota species (Canthocamptus staphylinus, Canthocamptus microstaphylinus, Parastenocaris brevipes, Lepadella ovalis, Lepadella patella, Rotatoria rotatoria, Rotatoria macrura, Asplanchna brightwelli, Trichocerca rattus, Euglena variabilis, and Flagilaria capucina) belonging to four (4) phyla (Arthropoda, Rotifera, Euglenozoa, and Ochrophyta) and 8 microbiota species belonged to four phyla (Arthropoda, Rotifera, Euglenozoa, and Ochrophyta) were identified from Ae. aegypti and Ae. albopictus breeding habitats respectively. There was a higher percentage (54.54%) of larval habitats positive for the secondary vector Ae. albopictus than through the primary vector Ae. aegypti in the Gampola urban area indicating higher possibility of transmitting the dengue virus through the secondary vector. However, no pathogenic or parasitic ciliates on mosquito larvae were encountered in the present study. Those findings may be due to sampling maingly from temporary container-type breeding habitats. Conclusions: The relative distribution of microbiota associated with mosquito species differed significantly among Ae. aegypti and Ae. albopictus. The overall findings of this study could help in implementing novel eco-friendly vector-control strategies in the study area.
