Abstract. Herlinda S, Tricahyati T, Irsan C, Karenina T, Hasbi, Suparman, Lakitan B, Anggraini E, Arsi. 2021. Arboreal arthropod assemblages in chili pepper with different mulches and pest managements in freshwater swamps of South Sumatra, Indonesia. Biodiversitas 22: 3057-3066. In the center of freshwater swamps in South Sumatra, three different chili cultivation practices are generally found, namely differences in mulch and pest management that can affect arthropod assemblages. The effect of mulches and pest management on arboreal arthropod assemblages specific to chili production centers in the freshwater swamps of South Sumatra has never been investigated. This study aimed to observe arboreal arthropod assemblages in chili with different mulches and pest management. Arboreal arthropods were sampled using sweep nets in three locations with plots treated with leaf litter mulch and bioinsecticide, plastic mulch and synthetic insecticide, and weedy plot without mulch with synthetic insecticide. The species number of arboreal arthropods found was 28 species of Arachnids and 23 species of Insects, and consisting of 6 families of the Arachnids and 25 families of Insects. The abundance of arboreal arthropods was 65.60 individuals/5 nets per observation. In the chili field without mulch but with the insecticide, the species biodiversity and abundance of arboreal predatory arthropods were the highest. In contrast, in the chili field, that applied with synthetic insecticides and plastic mulch, the abundance of arboreal predatory arthropods was the lowest. The herbivorous insect populations in chili with plastic mulch and synthetic insecticides and the chili with the leaf litter mulch were higher than those in the chili without mulch. In the chili with the leaf litter mulch and bioinsecticide, the species number and abundance of the spiders were the highest compared to the other chili fields. The weedy chili field without mulch and chili with the leaf litter mulch has proved ideal habitats for the arboreal predatory arthropods.
Cabai merupakan komoditas hortikultura yang memiliki nilai ekonomis tinggi, namun dalam budidayanya terdapat beberapa kendala dari hama dan penyakit. Penyakit yang sering ditemui yaitu penyakit kuning dan penyakit keriting daun yang disebabkan virus. Virus yang menyerang cabai biasanya ditularkan serangga vektor. Penelitian ini bertujuan untuk mengetahui respon serangga vektor yang tertarik pada masing-masing perlakuan warna mulsa yang akan berdampak pada insidensi dan intensitas penyakit. Percobaan dilakukan menggunakan tujuh warna mulsa plastik dan diulang sebanyak tiga kali, dan menggunakan rancangan acak kelompok (RAK). Variabel yang diamati meliputi insidensi dan intensitas penyakit kuning dan penyakit keriting daun, serta bobot dan jumlah buah cabai. Hasil percobaan menunjukkan bahwa penggunaan mulsa warna tidak berpengaruh pada insidensi penyakit virus kuning maupun insidensi penyakit virus keriting serta pada bobot buah dan jumlah buah cabai. Namun warna mulsa biru, kuning, merah, dan putih menghasilkan intensitas penyakit virus kuning maupun virus keriting yang lebih tinggi dibandingkan dengan mulsa warna hitam, coklat, dan hijau.
Abstract. Tricahyati T, Suparman, Irsan C. 2022. Natural enemies of Pentalonia nigronervosa, vector of Banana Bunchy Top Virus. Biodiversitas 23: 3675-3684. Pentalonia nigronervosa (Coquerel) is an important pest of banana. Instead of sucking liquid from banana phloem, P. nigronervosa also play an important role in transmitting Banana Bunchy Top Virus (BBTV) from infected banana to healthy ones. If efforts are not made to control the aphid, existence of P. nigronervosa can increase in the banana field. The objective of this research was to find out the natural enemies of P. nigronervosa which may play significant role in controlling the aphid naturally. The results showed that natural enemies were in the forms of predator, parasitoid and pathogenic fungi. A total of 22 species of predator belonged to 5 families of insect, namely Coccinellidae, Forficulidae, Chelisochidae, Reduviidae and Syrphidae, and 4 families of Arachnida i.e. Oxyopidae, Araneidae, Salticidae, and Philodromidae. The result exhibited that one parasitoid belonged to family Brachonidae, and one hyper-parasitoid belonged to family Encrytidae. Furthermore, it was also observed that 3 species of entomopathogenic fungi infected aphids. The fungi belonged to genera Aspergillus and Beauveria. Each predator had different predation capacity, the highest was that of Forficula auricularia (23.67 ± 3.05) and Scymnus sp. (23.67 ± 1.52). Parasitoid Lipolexis bengalensis could parasitize P. nigronervosa at relatively high parasitic ability of 4.67 ± 23.65. The finding of various natural enemies of P. nigronervosa in South Sumatra could be considered as an alternative way to control the aphid and reduce the transmission rate of BBTV in the province. The use of natural enemies has no residual effects on the environment and is relatively cheaper compared to other control measurements.
