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.

Implikasi keberadaan agens hayati Neochetina eichhorniae (Coleoptera: Curculionidae) terhadap eceng gondok Sapdi Sapdi; Damayanti Buchori; Utomo Kartosuwondo; S. Tjitrosemito; Bandung Sahari

The effectiveness of Neochetina eichhorniae as a biocontrol agent of waterhyacinth was evaluated in West Java and DKI Jakarta. The objective of this research was to study the implication of the existence of N. eichhorniae on waterhyacinth. Research was conducted in several freshwater ecosystem infested by waterhyacinth and N. eichhorniae, including Cibinong and Lido lakes (Bogor District), Muara Angke Sanctuary (North Jakarta), and Citarum Hulu river (Purwakarta District), conducted during April to August 2004. The impact of N. eichhorniae on waterhyacinth was evaluated by leaf damage intensity and growth parameter of the plant. Results showed that there was no correlation between waterhyacinth and the occurrence of the N. eichhorniae. The population of N. eichhorniae adults was significantly low in any locations studied. Thus, the existence of the biocontrol agent can not result in decreasing of waterhyacinth population.

The objective of this research was to identify parasitoids associated with eggs of Chrysopa in Lombok cashew ecosytem. Parasitoids were surveyed by collecting eggs of Chrysopa from cashew plantations. Total of 5900 individual parasitoids from a single species were collected from eggs of Chrysopa with parasitization level was approximately 47.0%-85.50%. The parasitoid was identified as Telenomus cyrus (Hymenoptera: Scelionidae).

Reproduksi Hemiptarsenus varicornis (Hymenoptera: Eulophidae) : pengaruh ketinggian tempat, suhu dan tanaman inang terhadap keperidian Reflinaldon Reflinaldon; Mardinus Mardinus; Dwinardi Apriyanto

H. varicornis is a larval parasitoid of leafminer distributing and associating with several host plants in highland vegetables planting. Three experiments were conducted to study effects of elevations, temperatures and host plants on female reproduction fitness. The first experiment, we compared fitness traits of female originated from different elevation areas i.e Pandai Sikek (900-1000 m above sea level ), Alahan Panjang(1200-1300m) and Kayu Aro (1400-1500m) whilst two other experiments were treatment of temperatures level (18, 23, 280C), and host plants (red bean, bean and cucumber) to investigate longevity, egg layed, survivorship. Parasitoids originated from Kayu Aro showed the highest longevity and number of eggs. The best fitness also was performed when adult female maintained at 230C. Parasitism, superparasitism and paralization of the parasitoid have been discussed in this paper.

Peluang investasi dan strategi pengembangan usaha budidaya kutu lak (Laccifer lacca Kerr): studi kasus di KPH probolinggo, perum perhutani unit II jawa timur Ira Taskirawati; F. Gunarman Suratmo; Dudung Darusman; Noor Farikhah Haneda

Shellac flea Laccifer lacca Kerr is a phytophagous insect, which lives on kesambi tree (Schleichera oleosa Merr). During its life cycle, shellac flea secretes liquid known as LAK and has many uses, such as varnish/polish, food cover, drug capsule, cassette ribbon, etc. In 2005, Perum Perhutani produced 60,547 kg LAK pellets, but has not fulfilled market demand. Cultivation technique is still conducted in a very simple way. Investment in developing shellac flea is also profitable, and promising. There are two choices of management schemes in it cultivate, the first is by infecting shellac flea to the host tree when the tree is 15 years old and the second is by infecting shellac flea when the tree is 4 years old. Financially, the latter approach is more beneficial than the former one. The value of NPV + 22 321 052 395, IRR 16.9%, BCR 1.55 and Net B/C 3.71 with discounted payback period for 10 year 8 months. SWOT analyzing was used in the design strategy as a management approach.

Nisbah kelamin dan pola peletakan telur parasitoid Trichogramma chilotraeae Nagaraja & Nagarkatti (Hymenoptera: Trichogrammatidae) pada berbagai jumlah inang hasriyanty hasriyanty; Damayanti Buchori; Pudjianto Pudjianto

The objective of the research was to study sex ratio and oviposition sequence of egg parasitoid Trichogramma chilotraeae in relation with host density under laboratory condition. Parasitoid response with respect to oviposition sequence was examined by exposing five different host (egg) densities: 3, 6, 12, 24 and 48 on female parasitoids T. chilotraeae. Results showed that in general, female parasitoid laid its female progeny at the beginning of oviposition sequence. Host density was found to have a strong effect on sex ratio. Sex ratio increase with increasing of host number.

Dampak non-target dari pengendalian hayati spesies asing terhadap ekosistem Damayanti Buchori

Non target impact of classical biological control of exotic species in the ecosystem. Classical biological control has been hailed as a successful control method of many exotic species of pests. However, recently this method of control has been questioned due to several cases of non target impact. Non target impact can occur two ways, i.e. direct non target impact when there is a host shift of the bioagents (e.g. changes in preferences), and the indirect non target impact which can occur through, among others, food web subsides that will change the overall interactions of many species within an ecosystem. The aim of this paper is to understand the interactions between introduced exotic agents (e.g. insects) toward local diversity, e.g. what are the implications of the interactions toward local biodiversity? Are there non target and indirect impacts of these introductions in Indonesia? The discussions covers the concept of biological control and conservation issues that should be taken into consideration, particularly in the context of insect conservation and impacts of classical biological control on island diversity.
