Semut merupakan salah satu anggota kelompok serangga yang memiliki keanekaragaman tinggi. Keanekaragaman semut meliputi keanekaragaman spesies dan keanekaragaman peran ekologis. Kajian mengenai keanekaragaman semut khususnya di wilayah Taman Nasional Baluran Jawa Timur belum banyak dilakukan, padahal kawasan tersebut memiliki potensi keanekaragaman hayati cukup tinggi. Koleksi spesimen semut di Kawasan Taman Nasional Baluran dilakukan di Ekosistem Hutan Musim. Koleksi spesimen menggunakan pit fall trap, umpan gula, umpan ikan, pengayakan serasah, dan koleksi langsung. Berdasarkan hasil identifikasi diperoleh 4 sub famili, 19 genus dan 40 spesies. Indeks keanekaragaman dianalisis menggunakan indeks keanekaragaman Shannon – Wiener (H’). Hasil analisis indeks keanekaragaman semut di hutan musim Taman Nasional Baluran adalah 2,268. Diacamma sp1, Paratrechina longicornis, Anoplolepis gracilipes dan Monomorium sp3 merupakan spesies yang paling dominan di hutan musim Taman Nasional Baluran.
Insects were collected from rice fields in Karawang West Java. Since insects are dominant in Rice field, their role in the ecosystem are important regarding the rice production. Therefore, the occurance of insect species and their role in ecosystem are important to understand. The aim of this reasearch was to study the insect occurance in rice field in Karawang to obtain the potential candidate for biological control agent. The insects were collected using sweep net, pit fall trap and light trap. Nine insect orders were collected and 49 morphospecies were identified including insect pest, parasitoids, predator, tourist and detritivore. Paederus sp., Cyrtohinus and Micraspis sp., were the most abundant entomophagous insect that is potential candidate for biological control agent in Karawang.
This community services activity was conducted together with a partner that is Benong II Farmers Group, in the Kalibuaya Village, Telaga Sari, Karawang. The problem that faced by partners is a lack of understanding of plant pest organisms (OPT), especially plant pests and diseases, as well as a lack of knowledge about the natural enemies. Knowledge and skills of the Benong II Farmers Group in the Kalibuaya Village, Telaga Sari, Karawang regarding the management and control of rice stem borer that environmentally friendly, especially biological control using parasitoid Trichogramma sp. needs to be improved. The evaluation results show that counselling and training on the breeding of natural enemies Trichogramma sp. resulting in the development and progress of the behavior, attitudes, and skills of farmers. There are four main results of the research. The results are (1) farmer more understand of the use of biological agents for IPM-based rice pest and disease control; (2) want to implement the control of rice stem borer Scirpophaga sp. by using Trichogramma sp.; (3) more skilled in monitoring the presence or absence of pests in rice plantations in the field; and (4) more active in finding out to community service teams, farmer group leaders, and POPT / field extension officers about how to mass culture theTrichogramma sp. and it's release techniques 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.
