Numerous plant species are utilised as valuable biological resources because active ingredients are inside them, which have been effectively exploited as insecticides. Pachygone ovata (Poir.), a plant species, exhibited characteristics of being predominantly non-aggressive and environmentally benign. However, its capacity to effectively regulate insect populations, namely mosquitoes, remained little explored. Dengue fever is an infectious disease caused by the dengue virus, which is predominantly transmitted by mosquito bites from the Aedes genus, with Aedes aegypti being the primary vector. This study examined the effect of an ethanolic extract derived from the leaves of Pachygone ovata on the survival rates of Aedes (Stegomyia) aegypti (Diptera: Culicidae) eggs and larvae in the laboratory of Acharya Nagarjuna University. Aedes aegypti is the arthropod vector that transmits the viruses that cause dengue fever, Zika virus, and Chikungunya fever. The vector has proved resistant to organophosphate chemicals used to combat the disease globally. Eggs and fourth-stage larvae of Aedes aegypti were exposed to three distinct concentrations of an ethanolic extract derived from the plant of P. ovata (C_1 = 0.0017 g/ml, C_2 = 0.0034 g/ml, and C_3 = 0.0051 g/ml) in a bioassay. The egg viability was greater than 70% in all three concentrations, whereas the larval mortality rate was greater than 70% in C_3.

This study aimed to ascertain the larvicidal and mortality activities of crude ethanolic extract derived from Euphorbia indica against larvae of Aedes aegypti and Culex vishnui. A preliminary test was conducted in order to ascertain the mortality rate ranging from 10% to 90%. The concentrations for the final test encompassed a range from 0.0998 g/L to 1.498 g/L alongside a single negative control. The LC50 and LC90 values of the ethanolic extract derived from Euphorbia indica leaf were determined to be 466.90 g/L and 868.42 g/L, respectively. The larvicidal effect of Euphorbia indica leaf is attributed to a chemical component that acts as a positive allosteric modulator of the GABA pathway. The collected data was subjected to analysis using the Kruskal-Wallis statistical test. Probit analysis was employed to examine the LD50 and LD90 values. The minimal lethal dose that resulted in 100% mortality of Culex vishnui larvae was determined to be 0.2 g/100 ml (p=0.01). The probit analysis yielded LD50 and LD90 values of 0.01 g/100 ml and 0.06 g/100 ml of aquades in Culex vishnui, respectively. The larvicidal efficacy of the dose was determined to have an LD90 value of 0.06 g/100 ml of aquades, but the LD50 value was found to be 0.01 g/100 ml of aquades. The assessment of Culex vishnui treatment involved comparing the number of mortality larvae and the number of living larvae from each treatment to the control group. In conclusion, the ethanolic extract derived from the leaves of Euphorbia indica exhibits promising potential for developing mosquito larvicides.

Dengue fever, caused by the Dengue virus (DENV), is a mosquito-borne disease that poses a significant public health threat in many parts of the world. The primary vector for dengue transmission in Tamil Nadu is the Aedes aegypti mosquito, which exhibits anthropophilic behavior and prefers breeding in stagnant water in residential areas. This research paper focuses on evaluating the effectiveness of using ovitraps, modified with locally available materials, for Aedes aegypti control in Chennai through community participation. Five sampling locations within Chennai were selected for the surveillance study (K.K. Nagar, Nesapakkam, J.B.A.S College, Triplicane and Royapettah). Ovitraps of 5 different colors, such as black, blue, red, orange, and white were used. The egg counts varied across different locations, time periods and different coloured ovitraps. Nesapakkam area exhibited the highest egg counts, suggesting the presence of factors such as poor sanitation and drainage that promote mosquito breeding. The results of the study showed that the highest number of Aedes aegypti eggs was collected during the months of February-March, indicating increased mosquito breeding activity during the dry season. The study also found that black and blue ovitraps yielded the highest number of eggs, while red, orange, and white ovitraps had lower counts. These findings highlight the potential effectiveness of color-coded ovitraps in capturing mosquito eggs and suggest the importance of seasonal monitoring and targeted vector control efforts. To protect the public from dengue/DHF, large-scale dengue prevention can be implemented by combining this system with other routine prevention measures. This will enable individuals to integrate and learn more about the effective control of dengue vectors.

Mosquitoes are most dangerous insect in the world and they cause many diseases to birds, animals and humans. The control of mosquitoes using plant product is more effectiveness. The current study evaluates the larvicidal bioassay of Chromolaena odorata leaf extracts carried out against fourth instar larvae of Culex quinquefasciatus. The extracts were obtained from solvent such as Petroleum ether, Chloroform, and Ethanol. Extracts from C. odorata were tested for larvicidal activity at levels ranging from 0.625 ppm, 1.25 ppm, 2.5 ppm, and 5 ppm. The mortality rate of the larvae was determined 24 hours, 48 hours, and 72 hours. The calculation of LC50 value of extracts was calculated after 48hrs exposure. After a 48-hrs exposure, the LC50 value of the extracts was calculated. After 48 hrs of incubation, the C. odorata Petroleum ether extract showed 100% mortality. C. quinquefasciatus was more susceptible to plant extracts. The crude extracts of C. odorata found to better results on vector control it may be active phytochemicals present in this extract to be explored and also plant-derived compounds have significant potential in mosquito vectors control programme.

Globally, the mosquito borne diseases are considered as the highest public health risk. In humans, dengue fever infection is one of the most threatening arboviral disease transmitted by the Aedes mosquito. These Aedes mosquitoes can survive almost any climatic conditions and are extremely determined. As a result, in September, 2023 an entomological survey has been undertaken to estimate the risk of vectors of vector borne diseases (VBDs) in Urban Region of Udaipur city of South Rajasthan to diminish potential health risks and prevent from vector borne disease (VBD). The cross-sectional survey was initiated in indoors to collect immature stage in Hiran Magri Sector-3, University College of Science, Ashok Nagar, Madri, Reti Stand, MLSU University Campus and Gyarawas and in around 103 houses of Udaipur city. Sampling of the mosquito larvae was conducted via dipper, pipette, and sieves and it depends on the container types. Morphologically the larvae were predicted and larval indices were also measured. Repeated surveys were undertaken in selected areas of Udaipur Urban. 60 containers were positive for Aedes mosquito larvae out of 128 inspected containers. Discarded Sinks, Thermocol Boxes and Disposable Plastic Cups most favorable for breeding whereas coolers were least favorable. Every entomological indices were found to be higher than the critical level for every selected areas according to guidelines given by World Health Organization, (2003; 2011). The larval indices that are House Index (HI), Container Index (CI) and Breteau Index (BI) were found 17.48, 46.88 and 58.25 percent respectively. (80%) Aedes aegypti and (20%) Aedes albopictus were identified from collected immature stages. To control these mosquitoes (Aedes), a cautious and constant surveillance of the study areas is recommended.

In this Research, we present a green synthesis method for selenium nanoparticles (SeNPs) using Typhonium trilobatum leaves and assess their potential applications. By utilizing different parts of T. trilobatum leaves as bioreductive agents, our research focuses on environmentally sustainable, safe, and socially responsible processes for the synthesis of selenium nanoparticles. Various biophysical techniques, including UV-Vis, FTIR, FESEM, TEM, EDAX, and XRD were employed to characterize the green-synthesized selenium nanoparticles (SeNPs). The toxicity of these biosynthesized SeNPs was evaluated against the dengue vector Aedes aegypti in its larval and pupal stages, indicating promising results at low concentrations (2 to 10 ppm). The study also examined the adulticidal activity, revealing significant mortality in adult Ae. aegypti following exposure to the biosynthesized SeNPs. Moreover, we exposed Ae. aegypti eggs to varying concentrations of leaf extract and biosynthesized SeNPs for 24 hours. After the treatment period, we transferred the eggs individually into distilled water cups and assessed their hatch rates 48 hours later. Moreover, both the T. trilobatum leaf extract and SeNPs demonstrated exceptional results in preventing the hatching of Ae. aegypti eggs aged 12 to 18 hours, achieving 100% mortality. Furthermore, the study investigated the predation effectiveness of Poecilia reticulata guppy fish on Ae. aegypti larvae in I to IV instar stages. The results demonstrated that biosynthesized SeNPs displayed significant larvicidal activity and enhanced the predatory potential of the guppy fish P. reticulata. These findings suggest that T. trilobatum leaf extract synthesized SeNPs as an eco-friendly strategy for controlling mosquito vectors during their early developmental stages.

An invasive Aedes Albopictus (Skuse, 1894) (Diptera: Culicidae) is considered one of the most crucial disease vectors. In this study, we aimed to monitor gradual changes in insecticide resistance profiles of Ae. Albopictus populations have recently invaded the Turkish territory. We collected Ae. Albopictus specimen from ten localities in the Black Sea, Marmara and Aegean regions in subsequent years. Adult Ae. Albopictus insecticide susceptibility to deltamethrin (0.05%), cyfluthrin (0.15%), etofenprox (0.5%), bendiocarb (0.1%), fenitrothion (1%) and dichloro diphenyl trikloroetan (DDT) (4%) was determined by the susceptibility test of World Health Organisation. Results showed common pyrethroid susceptibility. Bendiocarb and fenitrothion resistance was more common in the study. Interestingly, DDT resistance was still high in some populations despite the prohibition of the insecticide in Türkiye. A comparison of resistance status in two years demonstrated that populations were not under pyrethroid selection pressure in the study area. The fact that the bendiocarb and fenitrothion resistance, which was present when the populations were first established, continues after two years, demonstrates that the populations are under selection pressure in the study area. We believe that the findings in the study would help resistance management which is a major component of Ae. Albopictus control efforts.

Albopictus control efforts.","PeriodicalId":14127,"journal":{"name":"International Journal of Mosquito Research","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135448411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Entomological Surveillance of Dengue is one of the important aspects of vector control. The aim of this study was to find out the occurrence and abundance of breeding of Dengue Vector (Aedes) within different types of habitats at high risk areas for dengue transmission. Larval sampling was done indoor and outdoor. West Zone of MCD is divided into 29 wards; approximately 80% area of west zone falls in west district of Delhi. Various localities were covered for sampling of immature stage of Aedes. During this study, total 28,800 containers were examined from Jan 2020 to December 2021, out of 576 positive containers was reported. Plastic Containers (35.06%), Earthen Containers (26.56%), Iron Containers (26.04%), Cemented containers (7.46%), Rubber (4.51%) and Glass (0.34%). Maximum positive plastics containers (35.06%) was observed and minimum positive containers of Glass (0.34%) was observed. Therefore, to reduce larval habitats for Aedes breeding, use of water storage containers should be discouraged and another important tool as source reduction (Elimination of water stagnated containers) for the control of Dengue disease. There are two common species identified of Dengue vectors such as Aedes aegypti and Aedes albopictus which are responsible for the transmission of Dengue disease in Delhi.
