Abstract

AbstractPopulation density and bitting behaviour of insect vectors are several of the factors that influence the number of cases of malaria. This study aims to determine the relationship between population density and bitting behaviour Anopheles farauti which is a vector of malaria in coastal ecosystems (Biak Numfor Regency) and swamp ecosystems (Asmat Regency) with malaria cases. The method used is human landing collection conducted at 18:00 to 6:00 a.m. inside and outside the house. The results showed that the population density of An. farauti in coastal ecosystems is relatively lower than the swamp ecosystems. Man bitting rate in coastal ecosystems is 4 and 4.66, at 95.52 and 42.38 in swamp ecosystem. An. farauti on two ecosystems research are eksofilik. Population density and bitting behaviour An. farauti in coastal ecosystems and swamp ecosystems are not positively correlated with the number of malaria cases.Keywords: population density, biting behavior, An. farauti, Biak Numfor, AsmatAbstrakKepadatan populasi dan aktivitas menggigit serangga vektor merupakan salah satu faktor yang mempengaruhi jumlah kasus malaria. Penelitian ini bertujuan menentukan hubungan kepadatan populasi dan aktivitas menggigit Anopheles farauti yang merupakan vektor malaria di ekosistem pantai (Kabupaten Biak Numfor) dan ekosistem rawa (Kabupaten Asmat) dengan kasus malaria. Metode yang digunakan adalah human landing collection yang dilakukan pada pukul 18.0006.00 di dalam dan di luar rumah. Hasil penelitian menunjukkan bahwa padat populasi An. farauti di ekosistem pantai relatif lebih rendah dibandingkan ekosistem rawa. Man bitting rate di ekosistem pantai adalah 4 dan 4,66 di ekosistem rawa 95,52 dan 42,38. An. farauti pada dua ekosistem penelitian bersifat eksofilik. Kepadatan populasi dan aktivitas mencari darah An. farauti di ekosistem pantai dan ekosistem rawa tidak berkorelasi positif dengan jumlah kasus malaria.Kata kunci: kepadatan populasi, aktivitas menggigit, An. farauti, Biak Numfor, Asmat

Abstract

The Aedes aegypti mosquito is the vector that causes the spread of the Dengue virus that causes Dengue Hemorrhagic Fever. Breaking the chain of spread of Dengue fever has been done a lot, but it can cause negative impacts to environment. It is necessary to use other alternative solutions. One of them uses natural bioinsecticides from entomopathogenic fungi. The entomopathogenic fungus that has been widely developed as a bioinsecticide is Metarhizium anisopliae. Metarhizium anisopliae is a fungus which has larvicidal activity. Isolates of Metarhizium anisopliae were obtained from the Center for Forecasting Plant Pest Organisms, Karawang, West Java and Aedes aegypti larvae were obtained from Parasitology Laboratory, Faculty of Medicine, Public Health, and Nursing, UGM. The research was conducted from November 2021-April 2022 at the Entomology Laboratory, Faculty of Biology and the Parasitology Laboratory, Faculty of Medicine, Public Health, and Nursing, UGM, Yogyakarta. The method in this research is the culture and manufacture of a suspension of the fungus Metarhizium anisopliae with an average conidia density 0,9 x 107, 0,57 x 106, 1,175 x 105, 5,25 x 104, 3 x 104, 12,5 x 103 of conidia/mL, rearing of Aedes aegypti, bioassay, and data analysis using Probit Test with SPSS software version 23 to determine LC50. The effective concentration to kill 50% of larvae was 0.9 x 107 conidia/ml. There was no significant effect between each different concentration in killing Aedes aegypti larvae. The LC50 value obtained was 1.4 x 107. Metarhizium anisopliae was effectively to control Aedes aegypti larvae.
