“…aegypti abundance and serological data indicated that recent dengue infections were equally frequent in the intervention and control areas. The failure of the MosquiTRAP mass-trapping intervention may have resulted from its previously quantified poor performance relative to standard ovitraps (78.3% ovitraps positive for eggs vs. 46.4% MosquiTRAPs positive for adult females, p < 005, [53]) and the relatively low number of traps deployed per residence (three/house). More importantly, however, it is likely that the lack of pre-intervention source reduction campaigns also contributed to the poor performance of the relatively small MosquiTRAP due to competition from other water sources.…”

The intensifying expansion of arboviruses highlights the need for effective invasive Aedes control. While mass-trapping interventions have long been discredited as inefficient compared to insecticide applications, increasing levels of insecticide resistance, and the development of simple affordable traps that target and kill gravid female mosquitoes, show great promise. We summarize the methodologies and outcomes of recent lethal oviposition trap-based mass interventions for suppression of urban Aedes and their associated diseases. The evidence supports the recommendation of mass deployments of oviposition traps to suppress populations of invasive Aedes, although better measures of the effects on disease control are needed. Strategies associated with successful mass-trap deployments include: (1) high coverage (>80%) of the residential areas; (2) pre-intervention and/or parallel source reduction campaigns; (3) direct involvement of community members for economic long-term sustainability; and (4) use of new-generation larger traps (Autocidal Gravid Ovitrap, AGO; Gravid Aedes Trap, GAT) to outcompete remaining water-holding containers. While to the best of our knowledge all published studies so far have been on Ae. aegypti in resource-poor or tropical settings, we propose that mass deployment of lethal oviposition traps can be used for focused cost-effective control of temperate Ae. albopictus pre-empting arboviral epidemics and increasing participation of residents in urban mosquito control.

“…The positivity index for each species of Culicidae was estimated by dividing the number of positive sampled axils for a given species by the total A. macrorrhizos axils investigated (Gomes 1998). The positivity index is usually used in studies with Culicidae and is important because it reveals the percentage frequency of occurrence of a particular species on the sampled sites throughout the investigated period (Resende et al 2013).…”

Alocasia macrorrhizos (L.) G.Don grows and proliferates in shaded areas in several forest fragments in urban zones. The adult plant has axils that accumulate rain water (phytotelmata) and serve as breeding sites for several families of aquatic insects. The objective of this study was to determine the composition of the entomofauna associated with water accumulations in axils of A. macrorrhizos in urban areas of Manaus, Brazil. Individuals of A. macrorrhizos were sampled in five forest fragments, between April/2005 and March/2007 in urban areas of Manaus, totaling 184 sampling units. A manual suction hose was used for the removal of entomofauna. A total of 1,941 immatures of Diptera were collected representing the following families: Culicidae (96.5%), Chironomidae (2%), Psychodidae (0.7%), Ephydridae (0.7%) and Corethrellidae (0.1%). Five Culicidae species were identified: Wyeomyia melanocephala Dyar & Knab, 1906 (91.7%), Wy. ypsipola Dyar, 1922 (4.3%), Aedes albopictus (Skuse, 1894) (2.3%), Ae. aegypti (Linnaeus, 1762) (1.5%) and Johnbelkinia longipes (Fabricius, 1805) (0.1%). The members of Culicidae were the most abundant, confirming the importance of this group in communities associated with phytotelmata, with a positive relation to the volume of water (p < 0.05). The occurrence of Ae. aegypti and Ae. albopictus in axils of A. macrorrhizos demonstrates the potential of this Araceae as a breeding site of these medically important species. However, the real contribution of this Araceae in the maintenance and dispersion of populations of these two species of mosquitoes throughout the year should be further studied.

“…Walaupun demikian, ovitrap tidak akan efektif lagi jika ditempatkan lebih dari 1 minggu karena bisa menjadi tempat perindukan nyamuk baru . Selain itu, indeks ovitrap dapat menjadi alternatif teknik yang digunakan dalam pengendalian vektor selain survei jentik karena metode ovitrap juga dapat mendeteksi nyamuk dari tempat perindukan yang tidak terjangkau dari area di sekitarnya (Beech et al 2009;de Resende et al 2013) Aedes sp. akan bertelur setelah menghisap darah dan jumlah telur rata-rata 100 butir setiap kali bertelur.…”

ABSTRAKKejadian demam berdarah dengue (DBD) masih menjadi masalah kesehatan masyarakat di Indonesia. Pengamatan selama kurun waktu 20 sampai 25 tahun sejak awal ditemukan kasus DBD menyatakan bahwa angka kejadian luar biasa DBD mengalami peningkatan setiap lima tahun. Tujuan dari penelitian ini adalah 1) mempelajari keanekaragaman nyamuk Aedes di kota Sukabumi, 2) mengukur populasi Aedes sp. berdasarkan jumlah telur dan indeks ovitrap, dan 3) mengetahui hubungan indeks ovitrap dengan kondisi rumah. Telur Aedes sp. dikumpulkan dari 14 kelurahan di Kota Sukabumi yang memiliki angka insiden tertinggi, mulai dari bulan Mei 2015 hingga Agustus 2015. Pengumpulan telur dilakukan dengan cara memasang perangkap telur (ovitrap) sebanyak 230 buah di 115 rumah (di dalam dan di luar rumah). Hasil pengumpulan ovitrap menunjukan jumlah telur yang diperoleh dari ovitrap di dalam rumah 3 kali lebih banyak dibandingkan dengan telur dari ovitrap di luar rumah (1307 banding 429). Nyamuk Ae. aegypti ditemukan pada ovitrap di dalam rumah dan Ae. albopictus pada ovitrap di luar rumah. Indeks ovitrap di dalam rumah mencapai 60%, atau 1,6 kali lebih banyak dibandingkan dengan indeks ovitrap di luar rumah (37%). Rumah dengan ventilasi dan sanitasi buruk berisiko 3,09 kali meningkatkan angka indeks ovitrap. Hasil penelitian ini dapat digunakan sebagai informasi dasar bagi masyarakat untuk meningkatkan kebersihan lingkungan melalui pengurangan tempat perindukan nyamuk sehingga menurunkan kejadian DBD.Kata kunci: ovitrap, kondisi rumah, telur Aedes spp. ABSTRACTThe incidence of dengue hemorrhagic fever (DHF) is still a public health problem in Indonesia. Observations over a period of 20 to 25 years since the beginning of the discovering of the disease, has show the increase of the diseases incidence every five years. The purpose of this study are 1) study the diversity of Aedes's mosquitoes in Sukabumi City, 2) measure the Aedes population based on the number of eggs and ovitrap index, and 3) to know the correlation between ovitrap index and house condition. Aedes eggs were collected from 14 villages in Sukabumi City that has the highest incidence rate, started from May 2015 until August 2015. Collecting eggs is done by setting a trap eggs (ovitrap) as many as 230 pieces in 115 homes (indoor and outdoor). The results showed that Ae. aegypti were found inside houses and Ae. albopictus were outside houses. The number of eggs collected from ovitrap inside the houses were three times more than those collected from outside. Ovitrap index inside houses was 60%, or 1.6 times more than the ovitrap index outside the houses
