Abstrak : CIFOR adalah organisasi penelitian ilmiah yang berfokus pada hutan tropis di negara-negara berkembang dan dikelilingi oleh hutan sekunder dan daerah pemukiman. Peningkatan jumlah pemukiman telah menyebabkan perubahan habitat kupu-kupu dan dapat mengurangi populasi kupu-kupu di daerah tersebut. Tujuan dari penelitian ini adalah untuk mempelajari keragaman kupu-kupu di daerah CIFOR berdasarkan habitat yang berbeda dan hubungan keragaman kupu-kupu dengan faktor lingkungan. Pengamatan dilakukan dengan metode scan sampling pada pagi dan sore hari di dua lokasi yaitu, hutan sekunder dan daerah perumahan. Hasil penelitian menunjukkan bahwa 59 spesies dan 441 individu kupu-kupu ditemukan di daerah tersebut dalam waktu 8 minggu pengamatan. Di hutan sekunder dan daerah perumahan ditemukan 42 spesies (256 individu), dan 40 spesies (174 individu) kupu-kupu. Keragaman kupu-kupu lebih tinggi di daerah tersebut (H '> 3), di mana kawasan perumahan memiliki nilai lebih tinggi (H' = 3,34) daripada hutan sekunder (H '= 3,16). Indeks kesamaan Sorensen (CN) menunjukkan bahwa dua lokasi adalah struktur komunitas yang berbeda karena ada beberapa spesies dominan yang berbeda di setiap lokasi. Secara statistik, kecepatan angin memberikan pengaruh lebih signifikan pada jumlah individu kupu-kupu daripada parameter iklim lainnya. Hasil penelitian ini disarankan bagi CIFOR untuk lebih memperhatikan kondisi habitat kupu-kupu, terutama tumbuhan pakan larva yang makin berkurangKata kunci: Kupu-kupu, CIFOR, Papilionoidea, Hutan Sekunder, Daerah Pemukiman.Abstract : CIFOR is a scientific research organization that focus on tropical forests in developing countries and the area were surrounded with secondary forest and residential areas. Increasing number of residential area have caused changes of the butterfly habitat and may decrease butterfly population in the area. Aim of the research was to study the diversity of the butterflies in CIFOR area based on different habitats and the relation diversity of butterflies with environmental factor. The observations were done by scan sampling method in the morning and afternoon at two locations i.e., secondary forest and residential area. Results showed that 59 spesies and 441 individual of butterflies were found at the areas within 8 weeks of observation. At secondary forest and residential area were found 42 spesies (256 individu), and 40 spesies (174 individu) of butterflies. The diversity of butterflies was higher in the areas (H’ > 3), where residential area has higher value (H’ = 3,34) than secondary forest (H’ = 3,16). Sorensen similarity index (CN) showed that two locations were different community structures because there were several different dominant species at each location. Statistically, wind speed gave more significant influence on the number butterfly individuals than other climate parameters. It is recommended for CIFOR to pay more attention to the butterfly habitat conditions, especially the diminishing larval feed plants.Keywords: Butterfly, CIFOR, Papilionoidea, Secondary Forest, Residential Area.
Research on predatory predation of Paederus sp. (Coleoptera: Staphylinidae) was carried out to study the functional response of the predator Paederus sp. Functional response is a form and size predictor of consumer impact on resource populations, determining the effectiveness of a predator as an agent in biological control. Predation time in hungry and not-hungry conditions influences predator-prey interactions, which are essential in functional response. The method used in predating Paederus sp. on the prey of aphids was Aphid spp. They are using four levels of prey density with two different predator treatments. The results show the functional response model of Paederus sp. predators. against the prey of Aphid spp. Described in a type II model. The level of predation of Paederus sp. showed different results for the two treatments and an increasing cystoid curve at a rising rate. The level of predation is still increasing, along with the increase in host density, and can be a starting point for controlling the Aphid spp and using predators Paederus sp. in the field.
Butterflies are animals that are attractive to humans because they have the beauty of their bodies. In addition, beautiful and unique butterflies are also sought after by collectors for trade. Butterflies that are used as collections, must be preserved first. Preserving butterflies as part of environment-based learning can be supported by good preservation techniques that will improve teachers' understanding of butterflies and make insect recognition to kindergarten children more enjoyable. Therefore, learning about butterfly preservation accompanied by identification of butterflies needs to be conveyed in kindergarten. This research was carried out in TK Khalifah 7 Poligon, Palembang City. The purpose of the research is to describe the abality of kindergarten teachers to preserve butterflies. The method used in this research is a case study with a participation research approach. The results of the research showed; (1) The practice of butterfly preservation practice was responded well by the participants, and felt as valuable knowledge and skills in supporting learning activities on insect recognition material in the school environment; (2) The high interest and motivation of the training participants greatly supports the transfer of knowledge, can be absorbed by all and the resulting learning products meet scientific criteria; (3) The results of training in the form of dry butterflies in a storage box that have been identified in the home or school environment can be used as a learning device that supports the learning objectives of insect recognition in the school environment.
Parasitism research Trichogramma sp. (Hymenoptera: Trichogrammatidae) has been carried out with the aim of studying the functional response of the parasitoid Trichogramma sp. Functional response is one measure to determine the effectiveness of a predator or parasitoid as an agent in biological control, so that it can express a change in the number of preys attacked by individual predators. Temperature is one of the most important host-parasitoid interactions in functional responses. The method used in the parasitoid parasitism Trichogramma sp. on the host Corcyra sp. using four levels of egg density Corcyra sp. with two different temperature treatments (27OC and room temperature). The results show the functional response model of the parasitoid Trichogramma sp. against its host Corcyra sp. described in the type I model. Parasitization level of Trichogramma sp. showed the same results for both temperature treatments, however, it also shows differences in the speed of predation. It also showed linearity between the parasitoids Trichogramma sp. with the host Corcyra sp. Parasitism rates are still increasing, along with an increase in host density. This research can be a starting point to improve the control of Corcyra sp. using the parasitoid Trichogramma sp. in the field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
