Abstract

Drosophila elegans and D. gunungcola are closely related flower-breeding species, mainly exploiting Ipomoea flowers. Here, we report their territorial and mating behaviours in Ipomoea indica flowers at Cibodas, West Java, Indonesia. Flies of both species were almost absent from newly opened flowers in the early morning, and the number of individuals in flowers increased thereafter. Territorial males of these species fought against intruders of both species, but the frequency of fighting was significantly lower when intruders were heterospecific. Territorial males usually showed intensive courtship to conspecific females, but rarely to heterospecific females. Intensive courtship to conspecific females often led the females to desert the flowers, possibly because male’s courtship was annoying. The frequency of desertion was lower in D. gunungcola than in D. elegans. This difference may be attributable to the difference in sexual size dimorphism. Thorax size was smaller in males than in females in D. gunungcola but did not differ between the sexes in D. elegans, and therefore male courtship may be less annoying for females in D. gunungcola than in D. elegans. Copulation duration was shorter in D. elegans than in D. gunungcola, while the unreceptive period of females after copulation is shorter in D. elegans than in D. gunungcola.

Abstract

Untuk pertama kali di Indonesia tercatat sembilan jenis nyamuk yang diperoleh dari tunggul bambu, yaitu Aedes (Stegomyia) albolineatus. Orthopodomyia albipes, Heizmannia (Heizmannia) communis, Uranotaenia (Pseudoficalbia) bimaculata, Tripteroides (Rachionotomya) aranoides, Toxorhynchites kempi, Aedes (Finlaya) sp., Tripteroides (Tripteroides) sp. and Armigeres (Leicester) sp. Kunci untuk jenis ditampilkan. Uraian singkat untukmasing-masing jenis, bionomik, epidiomologi dan penyebaran jenis yang diketahui didiskusikan.

Abstract

ABSTRAKLatar belakang: Provinsi Kepulauan Bangka Belitung, lebih rincinya adalah Kecamatan Sungailiat, Kabupaten Bangka dilaporkan adanya kasus penyakit yang disebabkan oleh nyamuk, sehinggah penelitian ini bertujuan untuk mengetahui jenis dan pola distribusi nyamuk di tiga Kelurhan, Kecamatan Sungailiat, Kabupaten Bangka serta faktor-faktor yang mempengaruhi penyebarannya.Metode: Penelitian dilaksanakan bulan Mei sampai Agustus 2019 di Kecamatan Sungailiat, dengan menggunakan metode purposive sampling, HLC (Human Landing Collection) dan menggunakan analisis Indeks Morisita.Hasil: Hasil identifikasi dan pola distribusi  diperoleh 5 spesies nyamuk diantaranya Ae. aegypti, Ae. albopictu, Ar. sulbalbatus, Cx. hutchinsoni, dan Cx. quinquefasciatus dan memiliki pola distribusi mengelompok, dan dengan faktor lingkungan relatif sama dan merupakan faktor yang baik untuk perkembangbiakan nyamuk.Simpulan: Berdasarkan hasil perolehan nyamuk tertinggi adalah Cx. hutchinsoni. Ketiga genus ini menunjukan kecenderungan dengan pola distribusi mengelompok, disarankan untuk penelitian selanjutnya pencatatan waktu pengamatan secara teratur/jam untuk metode HLC. Kata kunci: Aedes, Armigeres,Culex, HLC, Bangka ABSTRACTTitle: Distribution of disease vector mosquitoes (Diptera: Culicidae) in Sungailiat Subdistrict, Bangka District  Background: In Bangka Belitung Islands Province, especially Sungailiat Subdistrict, Bangka Regency has reported many case of diseases caused by mosquito, This study aims to distribution patterns of mosquito in the three villages of Sungailiat Subdistrict, and the factors at influence.Method: The study was conducted from May to August 2019 in Sungailiat Subdistrict with the purposive sampling method, Human Landing Collection (HLC), the result was analyzes by the Morisita Index.Result: The results of identification and distribution patterns obtained by 5 mosquito species, Ae. aegypti, Ae. albopictu, Ar. sulbalbatus, Cx. hutchinsoni, and Cx. quinquefasciatus, with cluster distribution patterns, and with the same relative environmental factors and is a good factor by mosquito breeding.Conclusion:. Based on the result, the highest yield of adult mosquitoes was Cx. hutchinsoni. These three Genera show a tendency with clustered distribution patterns. It is recommended to further research the observation time regularly each hour for the HLC method.  Keywords: Aedes, Armigeres,Culex, HLC, Bangka
