Jurnal Entomologi Indonesia (JEI) publishes original research papers and short communications that covers the basic and applied aspect of insects and mites or other arthropods in agriculture, forestry, human and animal health, and natural resources and environmental management. The journal is published by Perhimpunan Entomologi Indonesia (Entomological Society of Indonesia). JEI was first published at the beginning of 2004 with twice per year in frequency on March and September. Since 2015, Jurnal Entomologi Indonesia has been published three times per year on March, July, and November.

To study insect community at orok-orok plantation (Crotalaria striata) from different habitat, we observed insects that interacted with Crotalaria plantation. There were four habitat type that used in this research, habitat open area and others were agroforestry habitat. We counted about nine ordo from insect that interacted with Crotalaria plant. More than 70% member of ordo, include to Hymenoptera, specially Formicidae. Not all function member of the ordo that known, but some of them are pollinator, parasitoid, predator and herbivore.

This research was conducted in three areas, which has different in altitudes; those areas are Gangga (50 m), Kayangan (4 m) and Bayan (170 m) above sea levels. The aim of this research was to observe monoculture system of cashew plantations from May 2007 until April 2008. The results of this research were (1) the number of Sanurus indecora J collected from the fields are 38.619 adults, which consist of 19.153 adult of green Sanurus and 19.466 adult of white Sanurus, (2) the number of Sanurus parasitited by Epipyropidae are 5.961 adult from 38.619, (3) the number of white Sanurus infested by Epipyropidae are 3.902 adult and 2.059 adult of green Sanurus, (4) white Sanurus is preferred by Epipyropidae than green Sanurus. Around 20 percent of white Sanurus adult are infested by Epipyropidae, (5) the parsitism of female Sanurus is higher compare to male.

The objective of the research was to study behaviour and parasitism efficiency of the egg parasitoid Trichogramma chilotraeae in relation to host and parasitoid density under laboratory condition. Eggs of Corcyra cephalonica were used as hosts for Trichogramma chilotraeae. Five different host (egg) densities: 3, 6, 12, 24 and 48 eggs were provided to one and two active female parasitoids T. chilotraeae. Percentage of parasitism, female progeny, and selfsuperparasitism were counted. Results showed that, host density was found to have a strong effect on parasitism rate, female progeny and selfsuperparasitism. Two parameters, parasitism and selfsuperparasitism decreases with increasing number of host density, in contrast, female progeny increase with increasing host density. Parasitoid density affected selfsuperparasitism and female progeny only on one level of host density (3 hosts) but not to all parameters of other density treatments.

Karakter kebugaran, seperti keperidian, lama hidup, dan fertilitas sering digunakan untuk menggambarkan kapasitas reproduksi suatu spesies. Oleh karena itu, kebugaran parasitoid sering digunakan sebagai indikator potensial dari suatu kualitas keberhasilan di lapangan. Karakter tersebut dapat pula menggambarkan persistensi populasi parasitoid di lapangan selama periode tertentu. Dalam pengelolaan hama, kebugaran parasitoid menjadi indikator penting untuk kesuksesan pengendalian hayati. Beberapa faktor yang berkaitan dengan kualitas parasitoid adalah pengaruh nang, lama generasi dan asal-usul parasitoid. Path analysis digunakan untuk menganalisa pola hubungan dan keterkaitan antar variabel kebugaran. Tujuan penelitian ini adalah untuk mengidentifikasikan indikator sukses dari perilaku parasitisasi serta mempelajari mekanisme hubungan sebab akibat (causal meechanism) antar beberapa karakter kebugaran dari (T. armigera) yang menyerang (C. capholonica) dan H. armigera. Hasil analisis menunjukan adanya korelasi yang tinggi dengan lama hidup. Pada inang Cocryra, ditemukan bahwa panjang sayap depan memiliki nilai positif dengan parasitisme, sedangkan ukuran kepala dan laju keberhasilan hidup dapat dikategorikan sebagai indirect indicator melalui jmlah telur yang dihasilkan.

Feeding supplementary food containing nony fruit juice was tested on honeybee colonies in honey producing . The aims of this research were (1) to determine the preference level of honeybees to the supplementary food containing honey and nony mixture, (2) to identify the organoleptic properties of the produced honeyessence of nony, (3) to determine fiber content of produced honey-essence of nony, and (4) to identify the colours of honey produced. The design used in the experiment was Latin Square Design. There were four treatments namely each concentration : A (0%) as control, B (12,5%), C (25%) dan D (37,5%) in dilution of supplementary food an amount of 600 grams wich consist of nony fruit juice and water. Each composition of dilution were A (300, 0, 300), B (225, 75, 300), C (150, 150, 300) dan D (75, 225, 300) . Every one replication was done for six days with six day interval. The result were as follows: The higher concentration of nony juice in the food suplement the smaller food were taken. The differences in the olour, the flavour and the taste of the artificial honey didn’ depend on the amount of the food suplement taken honey bees, but depend on nony fruits juice concentration in the honey produced. The higher concentration of nony fruit juice in the artificial honey produced the darken in colour, sour in taste and the weaken in flavour. Feeding with food suplement containing nony juice increases the fiber content in the honey.

Opius chromatomyiae (Hymenoptera: Braconidae) is an endoparasitoid attacking leafminers in the field. The objective of the research is to study the statitiscal demographic of the parasitoid. Result showed that female lifespan (9.95 days) was shorter than male (11.73). Female fecundity was about 104.73 eggs. with rate of egg production per day was about 9.31 eggs. This parasitois was also found to be female-biased sex ratio. Regarding population parameter, net reproduction rate (Ro) was about 28.55, of increase (λ) 1.23. The stable age of Opius chromatomyiae was about 37.93% eggs, 24.92 % larval, 20.36 % pupae and 16.78 % adult.
