Serangga atau insekta merupakan kelompok dari hewan beruas arthopoda yang berkaki enam. Sehingga ditemukan hampir disemua ekosistem, semakin banyak tempat dengan berbagai penggolongan jenis serangga berdasarkan aktivitasnya dikenal serangga yang aktif di siang hari dan serangga yang aktif di malam hari. Keberadaan jenis serangga di hutan bungkirit sangat penting karena hutan kota bungkirit memiliki fungsi sebagai area lingkungan yang menjaga ekosistem dan keanekaragaman hayati di Kota Kuningan serta memiliki fungsi sebagai sumber daya alam yang sangat tinggi berupa Flora Dan Fauna. Tujuan dari penelitian ini untuk mengidentifikasi jenis serangga di areal hutan kota bungkirit Kabupaten Kuningan dan untuk mengetahui tingkat keanekaragaman jenis serangga yang terdapat di areal Hutan Kota Bungkirit Kabupaten Kuningan. Penetian ini dilakukan dengan menggunakan metode Sweep Net dan Light Trap. Hasil penelitian menunjukkan terdapat 14 jenis serangga, nilai indeks keanekaragamannya (H’) adalah 2,31, indeks kemerataan pada lokasi sawah 0,90 mendapat nilai tertinggi sedangkan pada lokasi hutan campuran terdapat 0,88. Hasil perhitungan indeks sorenson mengetahui kesamaan jenis serangga pada lokasi penelitian sawah dan hutan campuran ditunjukkan dengan adanya kesamaan setiap lokasi penelitian sebesar 31% (sedang). Kata Kunci: Serangga, Hutan Kota, Sweep Net, Light Trap

The biting midge fauna of Dongzhaigang Mangrove Forest, Hainan Province, China was sampled on 14 October 2015 using three methods: a pan light trap operated from dusk until dawn the following morning and sweep net and human landing collections performed between 16:15–17:15 hr. Eight species, including two new records for China, Culicoides palawanensis and C. niphanae, and one new record for Hainan, C. circumbasalis, were collected. A key to assist with identification of specimens of these species is provided. DNA barcodes supported the morphological identification of some of these species and identified the potential presence of cryptic species and/or deep population structure in others. The newly recorded species were morphologically similar to species previously reported from Hainan, highlighting the need for further investigation into the taxonomy of biting midges in this region. Species composition and abundance varied considerably between the three collection techniques suggesting that multiple techniques likely provide a more comprehensive sample of biting midge fauna.

The results showed that there were 117 individuals insects which consist of 10 orders and 33 families. The highest relative density was 14.74% and the lowest was 0.42% sere recorded, while the highest relative frequency was 4.08% and the lowest was 1.53%. The value of insect diversity index was 3.115 (High), it is mean the diversities of insects varied and the habitat was good for growth of insects. The value of evenness index was 0.891 (high) and richness index was 4.15 (high). The dominant insects recorded from Order of Hymenoptera (Family of Formicidae), continued to Coleoptera (Family of Scarabaeidae; Coccinellidae) are quite diverse in the sorghum plantations. The function status of insects was recorded as herbivores, parasitoids, predators, pollinators and decomposer were determined.

A study on diversity and abundance of insects in rice field was conducted at farmer field of Lamahi, Dang during July to October in 2019. Insects were collected using sweep net and light trap. Overall, 414 insect specimen representing 11 families and 8 orders were collected during the period. Grasshopper (23.98%) with including all species was the most abundance insect found in rice field as it followed by brown plant hopper (16.62%). Among the eight insect orders captured Orthoptera (29.16%) was the most abundance insect order followed by Homoptera (16.62%). As the diversity of insect pest in this area may responsible economic losses was found which will be useful to adapt appropriate management practices to keep them at normal area. The presence of natural enemies should conserve to enhance the natural biological control of insect pests.

The fauna of Braconidae (Hymenoptera: Ichneumonoidea: Cheloninae, Opiinae, Rogadinae) was studied in different habitats of Kerman province, southeastern Iran. The specimens were collected using sweep net, Malaise traps and light trap during 2013 to 2018. Three subfamilies: Cheloninae, Opiinae and Rogadinae were identified in the present study. A total of 11 species belonging to six genera were identified. Among identified sample, a single species, Opius (Cryptonastes) ficedus Papp, 1979 (Opiinae) is reported for the first time from Iran.

Salah satu daerah di Indonesia yang menjadi sentra produksi kakao nasional adalah Sulawesi. Peningkatan produktivitas kakao berfokus pada pengendalian hama dan penyakit, optimalisasi penerapan teknologi budidaya, penggunaan jenis tanaman tertentu atau peremajaan tanaman yang telah tua, namun belum mempertimbangkan agen yang membantu dalam proses penyerbukan. Penelitian ini bertujuan untuk mengetahui jenis-jenis lebah pada kebun kakao di Lembah Napu, Sulawesi Tengah. Koleksi Hymenoptera dilakukan pada siang dan malam hari menggunakan sweep net dan light trap. Ditemukan sebanyak 4 spesies Hymenoptera yang termasuk dalam 2 famili yaitu Apis cerana., Apis dorsata, Ceratina sp., Champsomeris sp. Kelimpahan individu tertinggi di plot 2 yaitu 53 individu (49.07%), diikuti plot 1 yaitu 37 individu (34.26%) dan plot 3 dengan kelimpahan terendah yaitu 18 individu (16.67%). Keanekaragaman serangga tertinggi di Plot 2 yaitu H'=1.19, diikuti plot 1 yaitu H'=1.12 dan plot 3 dengan nilai terendah H'=0.98. Kemerataan serangga tertinggi di plot 3 dengan nilai E=0.34, diikuti plot 1 dengan nilai E=0.31, dan plot 2 dengan nilai terendah E=0,30. Lebah yang memiliki ukuran tubuh kecil yaitu Ceratina sp. dengan ukuran 8-10 mm. Namun dari segi perilaku kunjungan, Ceratina sp. tidak mengunjungi bunga kakao, sehingga lebah tersebut belum dapat disimpulkan sebagai lebah penyerbuk kakao yang potensial, meskipun memiliki ukuran yang kecil.

AbstractCertain fungus gnats, like Lycoriella ingenua are notorious pests in agriculture, especially in mushroom production. While larvae cause mainly direct crop damage, adults are vectors of several dangerous fungal pathogens. To promote the development of pesticide-free management methods, such as light trapping, we measured the spectral sensitivity of L. ingenua compound eyes with electroretinography and performed two different behavioural experiments to reveal the wavelength dependence of phototaxis in this species. The spectral sensitivity of the compound eyes is bimodal with peaks at 370 nm (UV) and 526 nm (green). Behavioural experiments showed that attraction to light as a function of wavelength depends on light intensity. In our first experiment, where the minimal photon flux (105–109 photons/cm2/s) needed for eliciting a phototactic response was determined wavelength by wavelength, phototaxis was strongest in the green spectral range (~526 nm). In the other behavioural experiment, where wavelength preference was tested under a higher but constant light intensity (~1013 photons/cm2/s), the highest attraction was elicited by UV wavelengths (398 nm). Our results suggest that both UV and green are important spectral regions for L. ingenua thus we recommend to use both UV (~370-398 nm) and green (~526 nm) for trapping these insects.
