Abstract

Introduction: Anopheles mosquito is transmitting malaria, one of the health problems in Indonesia. Understanding Anopheles mosquito behaviour and its breeding preference is one of the crucial keys to prevent malaria transmission. This study aimed to identify the breeding place distribution and bionomics of Anopheles spp. in Runut village, Sikka district, East Nusa Tenggara. Methods: A descriptive observational study was conducted in Runut village, Waigete sub- district, in April 2018. Anopheles spp. larvae were collected in 7 suspected breeding places consisting of 2 rice fields, 3 fish ponds, and 2 puddles. Mosquitos behaviour was observed using bed-net traps located inside and outside the house from 7.15 PM to 1.15 AM after obtaining informed consent. Mosquito collection using bed-net trap were performed for 40 minutes then followed by resting mosquito collection for 10 minutes. Results: Anopheles spp. larvae were found in most of the suspected aquatic habitats, presenting different densities and together with larvae of the other mosquito species. Relatively high number of Anopheles spp. larvae was obtained from a puddle. Only one female mosquito of Anopheles spp. resting on the wall inside house was found around 00.55 – 01.05 AM and resulted in low mosquito density determination. Conclusion: Anopheles spp. larvae were harbouring in most of the aquatic habitats and one puddle contained moderately abundant larvae of Anopheles in Runut village, Sikka district, East Nusa Tenggara, Indonesia. Even only one Anopheles spp. mosquito was detected inside the house, residents in Runut village should regular use insecticide-treated bed nets and continuous observation of mosquito breeding places especially puddles to prevent malaria and other mosquito-borne diseases.

Abstract

Aedes aegypti transmits the dengue virus that causes Dengue Viring the high number of DVI cases is the existing breeding places of Ae. aegypti. The water sources used by the community and the surrounding environment are essential media for living Ae. aegypti larvae. This recent study aimed to detect the longevity of Ae. aegypti larvae in diff erent water sources in Surabaya and the killing effect of temephos. An analytical observational and experimental study was conducted in August-September 2021. Twenty-instar III Ae. aegypti larvae were put in each 100 ml beaker glass containing diff erent water sources, such as rain, well, mineral, new and used bath water, and antiseptic soapy water. Fungi in water sources were examined. Two groups were set with and without temephos, the final temephos concentration was of 0.00001 ppm. Live Ae. aegypti larvae, pupae, mosquitoes were observed every 24 hours for seven days without feeding. Living larvae were still found on Day 7 in all water sources with and without temephos. There were more larvae live in soapy water without temephos, particularly on Day 2 to Day 6, compared to other water sources either without or with temephos. In contrast, many larvae died in mineral water with temephos. Some larvae turned into pupae, started on Day 1. Pupae and mosquitoes were mostly found in rain water with temephos. Ae. aegypti larvae survived better in soapy water either with or without temephos. Temephos seemed to be effective to kill Ae. aegypti larvae in mineral water, and might induce larvae in turning to pupae and mosquitoes quickly at low concentration.
