GOS is an outdoor area in urban areas planted with various types of plants. Around the settlement of Banjarbaru City there is GOS with various types of plants used by Ae. aegypti and Ae. albopictus as a breeding place.  The abundance of the population of Ae. aegypti and Ae. albopictus in GOS will attract the presence of various mosquito predators, including the predatory larvae of Toxorhynchites splendens. This research was conducted in the GOS area around settlements and rubber plantations in Banjarbaru City, with the aim of finding out: (1) habitat characteristics of preadult Tx. splendens in rubber plantations and their predation ability; (2) the area, density, and type of vegetation that make up the GOS around settlements; and (3) population characteristics of Ae. aegypti and Ae. albopictus in GOS. The preadult Tx. splendens population study was conducted March-October 2020. The study was conducted by roaming method, by observing preadult mosquitoes in rubber sap containers, followed by calculating container index (CI) and testing predation ability.  Research on measuring the area of GOS and population characteristics of Ae. aegypti and Ae. albopictus was conducted from September 2021-March 2022. The GOS area was mapped with sentinel-2 satellite imagery and analyzed using the normal different vegetation index (NDVI) method.  Population characteristics of Ae. aegypti and Ae. Albopictus in GOS was studied by egg surveillance method, also counting the number of eggs with ovitrap positively index (OPI). The results showed that the CI index of Tx. splendens from March to October ranged from 20%- 100%.  Tx. splendens larvae are capable of preying on Ae. aegypti larvae and Cx. quinquefasciatus were 10.6 per day and 12 per day respectively and became pupae with an average of 14.55 days and 12 days, respectively. The GOS area around the Banjarbaru city settlement is covered by 61?nse vegetation, with an OPI index Ae. aegypti and Ae. Albopictus reaches 100?ter 6 days of ovitrap insertion.  The conclusion of this study is that Txsplendens are still found in the rubber plantation area of Banjarbaru City which is able to prey on Ae. aegypti larvae and Cx. quinquefastiatus and GOS around the settlement of Banjarbaru City become the habitat of Ae. aegypti mosquitoes and Ae. albopictus."> <xml> </xml><![endif]--><!--[if gte mso 9]><xml> Normal 0 false false false EN-US X-NONE X-NONE </xml><![endif]--><!--[if gte mso 9]><xml> </xml><![endif]--><!--[if gte mso 10]> <style> /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";} </style> <![endif]--> Aedes aegypti and Ae. albopictus is anthropophilic, this mosquito occupies habitats close to human existence, such as Green Open Space (GOS).

Aedes aegypti dan Ae. albopictus bersifat anthropofilik, sehingga mencari habitat yang dekat dengan keberadaan manusia.  Ruang Terbuka Hijau (RTH) merupakan areal luar rumah di perkotaan yang ditanami berbagai jenis tanaman. . Tanaman di RTH sekitar permukiman Kota Banjarbaru didimanfaatkan Ae. aegypti dan Ae. albopictus sebagai breeding place.  Populasi nyamuk Ae. aegypti dan Ae. albopictus yang melimpah di RTH akan menarik berbagai predator nyamuk datang termasuk larva predator Toxorhynchites splendens.  Penelitian ini dilakukan di wilayah RTH sekitar permukiman dan perkebunan karet di Kota Banjarbaru dengan tujuan untuk mengetahui: (1) karakteristik habitat Tx. splendens pradewasa di perkebunan karet dan kemampuan predasinya; (2) luas area, kerapatan, dan  jenis vegetasi penyusun RTH sekitar permukiman; dan (3) karakteristik populasi Ae. aegypti  dan Ae. albopictus di RTH. Penelitian populasi Tx. splendens pradewasa dilakukan bulan Maret 2020-Oktober 2020 dengan metode jelajah dengan cara mengamati pradewasa di wadah getah karet yang dilanjutkan dengan penghitungan indeks kontainer (CI) dan pengujian kemampuan predasi.  Penelitian luas wilayah RTH dan karakteristik populasi Ae. aegypti dan Ae. albopictus dilakukan dari bulan September 2021-Maret 2022. Luas wilayah RTH dipetakan dengan citra satelit sentinel-2 dianalisis dengan metode normal different vegetation index (NDVI).  Karakteristik populasi Ae. aegypti dan Ae. albopictus di RTH dikaji dengan metode surveilans telur dan dilakukan penghitungan jumlah telur dengan indeks ovitrap positively index (OPI). Hasil penelitian ini menunjukkan bahwa indeks CI Tx. splendens dari bulan Maret sampai oktober dari 20%- 100%.  Larva Tx. splendens mampu memangsa larva Ae. aegypti dan Cx. quinquefasciatus berturut-turut sebanyak 10,6 ekor/hari dan 12 ekor/hari dan menjadi pupa berturut-turut dengan rata-rata 14,55 hari dan 12 hari. Wilayah RTH sekitar permukiman kota Banjarbaru tertutup vegetasi rapat seluas 61?ngan indeks OPI Ae. aegypti dan Ae. albopictus mencapai 100% setelah 6 hari pemasangan ovitrap.  Kesimpulan dari penelitian ini adalah Tx. splendens masih dijumpai di wilayah perkebunan karet Kota Banjarbaru yang mampu memangsa larva Ae. aegypti dan Cx. quinquefastiatus  dan RTH sekitar permukiman Kota Banjarbaru menjadi habitat nyamuk Ae. aegypti dan Ae. albopictus.
