Abstract

Fruit flies are common pests of edible and commercial fruit crops. The presence of fruit flies can be detected using male attractant, but the species obtained mostly unknown on the host plant. The host rearing method for fruit infested with fruit flies can be use to see the distribution of host plant species and families. This research aims to determine the diversity of fruit flies pest species and the distribution of their host plants on horticultural fruit cultivated in Bangka Regency, Bangka Belitung Islands Province. A total of eight sub-districts in Bangka Regency surveyed using purposive sampling. The results showed that nine species of fruit plants were infested by six species of fruit flies. Five species of fruit flies have pest status, namely Bactrocera albistrigata, Bactrocera carambolae, Bactrocera dorsalis, Bactrocera sp1, and Zeugodacus cucurbitae and one species has non-pest status, namely Bactrocera mcgregori. Bactrocera dorsalis infested eight of the nine host plants. Bactrocera dorsalis, Bactrocera carambolae, and Bactrocera albistrigata were found in eight sub-districts. The fruit flies Bactrocera dorsalis and Bactrocera carambolae are the dominant species in Bangka Regency, Bangka Belitung.

Abstract

Fall Armyworm (Spodoptera frugiperda J.E. Smith) is a new pest species in Indonesia which has the potential to attack corn plantation in Mendo Barat District because it has the highest harvested corn area in Bangka Regency. The purpose of this study was to determine the attack intensity, Symptom Characteristics and distribution of S. frugiperda on corn plantations in Mendo Barat District, Bangka Regency. The study had been conducted in November 2019 to February 2020 using the observation method. Study sites and sampling techniques was carried out by using purposive sampling technique. The results showed S. frugiperda larvae had the same characteristics as those found in Africa, namely the inverted Y pattern on the head, four black dots on the eighth dorsal segment, thick bands on the lateral part and three bright lines on the upper body. Symptoms of an attack in the early vegetative phase of corn were transparent holes in the leaves and shoots, while in the reproductive phase were damaged cob and corn kernels. The number of caterpillars, the highest number of plants attacked and damaged were found in Petaling Banjar Village by 55% intensity of severe attacks. The intensity of relative damage was at 31.6%. Most of the plants attacked and damaged by S. frugiperdawere found mostly in the tasseling and silking (R1) phase and monoculture planting systems. We conclude the S. frugiperda attacked the corn plants in Mendo Barat District and caused various kinds of damage in accordance with the growing stage of corn plants.

Abstract

Taman Wisata Alam Gunung Permisan, Kabupaten Bangka Selatan merupakan kawasan konservasi yang berisi flora dan fauna. Keanekaragaman fauna di kawasan konservasi penting untuk diperhatikan karena fauna dapat menjaga keseimbangan ekosistem alam. Selain itu, jenis fauna tanah juga dapat digunakan sebagai bioindikator dalam perubahan habitat, seperti semut, hal ini dikarenakan kepekaannya yang tinggi terhadap gangguan habitat. Penelitian tentang keanekaragaman semut di Bangka juga masih terbatas, sehingga perlu dilakukan penelitian ini terutama di Bukit Nenek sebagai tempat konservasi. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis semut dan mengetahui keanekaragaman semut di Taman Wisata Alam Bukit Nenek Gunung Permisan Kabupaten Bangka Selatan dengan menggunakan metode pitfall trap, hand collection dan beat sheets. Analisis yang digunakan adalah indeks keanekaragaman, kekayaan jenis, kemerataan, kelimpahan relatif, dominasi dan hubungan antara keberadaan semut dengan parameter lingkungan menggunakan analisis PCA. Penelitian dilakukan di 7 stasiun dengan 21 petak dengan menggunakan metode Berdasarkan penelitian yang telah dilakukan, ditemukan 23 jenis semut dengan 5 subfamili yaitu Cerapachyinae, Dolichoderinae, Formicinae, Myrmicinae dan Ponerinae. Hasil analisis PCA menunjukkan bahwa terdapat hubungan positif antara jumlah individu semut dengan suhu udara, kelembaban udara, kelembaban tanah sedangkan jumlah spesies semut berkorelasi positif dengan suhu udara, kelembaban udara, kelembaban tanah dan pH.
