Abstract

Decomposition is an important process in nature, as it can break down organic matter into smaller particles and nutrients. Nutrients are returned to the environment and can be reused by other organisms. One important organism that plays a role in the decomposition process is termites because termites are able to decompose organic matter such as wood in all habitats. Different termite habitats can be seen in terms of different types of land use. Some types of land use, such as natural forests, secondary forests, palm oil plantations, and settlements, can be used as a test site for wood decomposition by termites. All types of land use can be found in Dharmasraya Regency, West Sumatra Province. The purpose of this study was to study the decomposition of wood by termites in several different types of land use. Four types of land use are selected from habitats with the least disturbed conditions to the extent of high habitat disturbances, namely natural forests, secondary forests, palm oil plantations, and settlements. The study was conducted in Dharmasraya Regency, West Sumatra Province. The research method uses pine wood bait (Pinus merkusii), measuring 1.9 cm x 1.9 cm x 25 cm. The wooden bait is winded for seven days, and the wood bait is weighed to gain its initial weight and measured moisture content. Furthermore, wood bait that has been installed is observed and re-weighed to gain final weight and measured water content. The results showed that deforestation in Dharmasraya, West Sumatra had an effect on reducing wood decomposition by termites. Five (5) termite species were found in wood bait, including Pericapritermes sp.1, Microtermes sp.1, Schedorhinotermes sp.1, Macrotermes gilvus, and Coptotermes curvignathus.

Abstract

Parasitoid A. lopezi dintroduksikan ke Indonesia pada 2014 untuk mengendalikan kutu putih asing invasif P. manihoti. A. lopezi berinteraksi dengan predator P. ramburi dan C. montrouzieri pada pertanaman singkong yang terserang kutu putih P. manihoti. Penelitian bertujuan untuk mengkaji pengaruh interferensi kedua predator terhadap keefektifan A. lopezi pada P. manihoti. Percobaan dilakukan di dalam laboratorium dengan menggunakan cawan petri dan kurungan serangga. Nimfa kutu putih instar-3 dipaparkan pada kedua predator selama 24 jam. Pengamatan dilakukan terhadap perilaku parasitoid dan tingkat pemangsaan predator. Kehadiran predator berpengaruh nyata terhadap penurunan masa kunjungan, masa penemuan inang, dan jumlah telur yang berhasil diletakkan oleh A. lopezi pada nimfa kutu putih. Kedua larva predator mampu memangsa kutu putih yang tidak terparasit dan yang terparasit umur 1-8 hari. Predator mampu mendikriminasi kutu putih yang terparasit umur 14 hari (mumi). Pemangsaan predator terjadi pada kutu putih yang terparasit umur 1-, 3-, dan 8- hari. Kombinasi parasitoid dengan kedua predator menunjukkan adanya interaksi antagonis. Kehadiran predator P. ramburi dan C. mountrouzieri menurunkan tingkat parasitisme A. lopezi pada P. manihoti.

Abstract

The most dominant mealybug species found on cassava is Phenacoccus manihoti. Parasitoid Anagyrus lopezi is a biological agent of P. manihoti in many countries. Monitoring the incidence and population of mealybug and the percentage of parasitization were done, as well as the population of ants and predator insects for 12 consecutive months. The highest incidence and attack rate of mealybugs were 26 and 64%, respectively, during the dry season. A. lopezi was able to suppress the population of P. manihoti between 2-17 individuals per plant with a parasitization rate varied from 12 to 46%. Our study showed that the parasitization rate of A. lopezi increased significantly with the increase in mealybug density. Predators P. ramburi and C. montrouzieri were found in low populations and have not had a significant impact on the mealybug population. Our study demonstrated the important role of natural enemies in suppressing the mealybug population on cassava

Abstract

Aphids (Hemiptera: Aphididae) are considered as one the most important pest in the world. Some species of aphids were reported as serious pests and plant virus vectors, especially on horticultural crops. Weeds in the agricultural area can serve as an alternative hosts for some aphids which are plant pests or plant virus vectors. The objective of this research was to identify aphid species of weeds in the agricultural production area in West Java and to provide the identification key. Aphids collection was done on the weeds in the agricultural fields in 9 districts of West Java. Aphids were collected from 13 species (5 families) of weeds. The identification of aphid was peformed based on the adult specimens. The research manased to come up with 12 species of aphid on weeds. Three of the 12 collected species were Epameibaphis frigidae (Oestlund), Metopolophium dirhodum (Walker), and Pseudaphis sijui (Eastop) has never been reported in West Java. Six species were known as vectors of plant viruses in agricultural crops. The most commonly found aphid species was Schizaphis graminum (Rondani) in the yard grass (Eleusine indica).

Abstract

Parasitoid Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) was introduced from Thailand into Indonesia in early 2014 to control the invasive cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). Research was conducted in laboratory with the objectives to determine effect of honey on adult longevity, to study fecundity, progeny production, and sex ratio, and to evaluate effect of increased host density to parasitization. Studies were carried out by exposing 3rd instar nymphs of mealybug to parasitoids. Effect of honey on adult longevity was done in the absence of hosts. Fecundity was measured by the number of mummies formed. Results showed that adult females lived for 3.7 days, while males lived for 3.2 days when only provided water. Adult longevity increased significantly when honey was provided. Parasitoids with access to 50% honey lived almost six to nine fold longer than those provided water. Over its adult life, A. lopezi parasitized 96–287 mealybugs with an average of 203.7 or 34.6% of hosts were parasitized, and 24.86% were killed through host feeding. Development from egg to adult emergence required 17.97 and 17.67 days for males and females respectively. The average number of offspring produced per female was 88.8 individuals, of which 56.9% were females. The number of hosts parasitized at densities varying from 2–100 cassava mealybugs corresponded to a type III functional response.

Abstract

Fruit fly (Diptera: Tephritidae) is one of the important pest in horticultural plants which can cause quantitative and qualitative losses of production. One of the potential natural enemies to control the fruit flies is parasitoid. The aim of this research was to study the diversity of fruit flies and its parasitoids in Mekarsari Fruit Garden. The research was carried out in March to August 2017. Identification of fruit flies and parasitoids was conducted at Insect Biosystematics Laboratory, Institut Pertanian Bogor. Fruit flies were collected by setting Steiner traps and collecting infested fruits. In each sampling point, two traps were installed useing two different attractants, i.e. methyl eugenol (ME) and cue lure (CL). Steiner traps were set up for six weeks and the trapped fruit flies were taken every week. Collected fruits were 1 kg for each fruits species, within 1-6 timed depend on fruit existence. Based on ME attractants, 4 species of fruit flies were identified, i.e. Bactrocera (B.) carambolae, B. (B.) umbrosa, B. (B.) dorsalis, and B. (B.) occipitalis, while 6 species were attracted by CL, i.e. B. (B.) albistrigata, B. (Z.) calumniata, B. (Z.) caudata, B. (Z.) cucurbitae, B. (Z.) tau, and D. (C.) longicornis. Three parasitoids (Hymenoptera: Braconidae) were found from rotting fruits, i.e. Diachasmimorpha longicaudata (Ashmead), Fopius arisanus (Sonan), and F. vandenboschi Fullaway.

Abstract

Strawberry (Fragaria x ananassa Duch) is a horticultural crop whose pollination partly depends on insects. Study was conducted in a strawberry field in Ciwidey-Bandung, with the objective to assess the contribution of flower-visiting insects to strawberry pollination. In this study, the contribution was assessed by pollinators abundance, duration of visits to flower, and pollination efficiency i.e. number of developed achenes, fruit weight and size, and ripening time. The study recorded four most frequent strawberry flower visiting insects which were two hoverfly species:  Episyrphus balteatus (Deg.) (47.3%) and Melanostoma sp. (33.8%); and two bee species: Lasioglossum sp. (7.0%) and Asian honey bee Apis cerana Fabricius (5.3%). Duration of visit per flower by the hoverflies was 7.75–10,00 minutes and by the bees was 0.25–0.79 minutes. Fruits developed from flowers that had received a single visit by each insect species had more number of developed achenes (1.6-1.8 times), higher fruit weight (1.8–2.3 times), bigger fruit size (1.2–1.3 times), and shorter ripening time (1–3 days), compared to those fruits developed from flowers not visited by the insect. The presence of bees and hoverflies play an important contribution to strawberry pollination in Ciwidey. Our findings have implications for increasing strawberry yield through management of insect pollinators.

Abstract

Kutu putih Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae) merupakan salah satu  hama yang paling dominan pada tanaman singkong (Manihot esculenta). Hama ini pertama kali terdeteksi di Indonesia pada tahun 2008. Parasitoid Acerophagus papayae Noyes & Schauff (Hymenoptera: Encyrtidae) merupakan agens hayati eksotik yang potensial mengendalikan kutu putih di banyak negeri. Penelitian ini bertujuan untuk mengkaji dinamika penekanan populasi P. marginatus oleh musuh alami di lapang. Monitoring dilakukan dengan cara mengamati 50 tanaman contoh setiap bulannya. Peubah yang diamati meliputi insidensi serangan dan populasi kutu putih, persentase parasitasi dan hiperparasitasi serta populasi predator pada tiga kebun singkong selama 12 bulan berturut-turut. Insidensi serangan dan tingkat serangan kutu putih tertinggi masing-masing sebesar 26% dan 64% terjadi pada musim kemarau. Parasitoid A. papayae mampu menekan populasi P. marginatus antara 1-15 ekor per tanaman dengan tingkat parasitisasi 9-16%. Dinamika parasitisasi parasitoid bergantung pada kelimpahan kutu putih di lapangan. Hiperparasitoid yang ditemukan menyerang parasitoid tersebut adalah Chartocerus sp. (Hymenoptera: Signiphoridae) dan Prochiloneurus sp. (Hymenoptera: Encyrtidae). Hiperparasitisasi Chartocerus sp. pada A. papayae berkisar 0.87-1.05%, sedangkan hiperparasitisasi Prochiloneurus sp. pada A. papayae berkisar 0.47-1.35% per tanaman. Predator Plesiochrysa ramburi dan Cryptolaemus montrouzieri sangat rendah populasinya di lapangan sehingga tidak memberikan dampak yang nyata terhadap fluktuasi populasi kutu putih.

Abstract

Spodoptera frugiperda (UGJ) pertama kali dilaporkan di Indonesia pada tahun 2019. Hama ini pertama kali dilaporkan sebagai hama invasive dan bergerak cepat dari Amerika Selatan ke Amerika Utara sejak tahun 1970-an, dan masuk ke Eropa tahun 1990, dan tahun 2016 menyebar ke Afrika dan lalu Asia. sejak invasif pertama kali pada tahun 2016 di Afrika. Serangan hama ini diketahui dapat menyerang 100% pertanaman. Di Sumatera Utara, hama ini diketahui telah menyebabkan penurunan pendapatan petani hingga 26% dan meningkatkan ongkos pestisida hingga 71%. Di lapangan telah ditemukan berbagai jenis musuh alami yang mampu menyerang dan mengakibatkan kematian pada berbagai instar UGJ. Parasitoid utama yang ditemukan di lapang adalah Telenomus remus, dan parasitoid larva Microplitis snellenius. Ditemukan juga kompleks parasitoid lain dan kompleks predator misalnya Sycanus, Carabidae, Coccinellidae. Penelitian di laboratorium menunjukkan tingginya tingkat keefektifan serangan musuh alami, yang bisa membunuh hingga 70% populasi. Hasil ini menunjukkan bahwa kompleks musuh alami perlu dikembangkan segera sebagai salah satu teknologi pengendalian ramah lingkungan.
