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.

The research was conducted in the field of Taro village Gianyar regency and Katung village Bangli regency and at the Laboratory of Biotechnology Faculty of Agricultural Udayana University. The purpose of the research were to investigate population dynamic of Diaphorina citri Kuwayama and other insects that were assosiated with citrus cv. siam; and molecular detection of CVPD patogen in its vector, other phytophagous insects on citrus cv.siam and kemuning [Murraya paniculata (L.) Jack.] The result of this study showed that in six month period there was one peak of D. citri population which was associated with the flushing period of citrus at Taro as well Katung villages. The peak of D. citri population of Taro village was higher than that of Katung village. Two species of parasitoids and four spesies of predators were found in the field and may contribute in the suppression of D. citri population. The parasitoids identified were Tamarixia radiata Wat. and Diaphorencyrtus alligharensi Shaffe, whereas the predators were Curinus coeruleus Mulsant, Phiddipus sp., Menochilus sexmaculatus Fabricius and Oxyopes javanus Thorell. T. radiata has been proven to be an effective nymph parasitoid that could suppress the population development of D. citri in citrus orchads. The research revealed that kemuning could serve as a source of infection because it is also a host of CVPD disease as well as of D. citri. Toxoptera citricidus Kirkaldy and Maleuterpes dentipes Hell. were not proven to contain CVPD disease.

Agricultural intensification cause negative effect to insect diversity including beneficial insect such as natural enemies and pollinators. Habitat management through habitat heterogeneity is an alternative approach to protect insect diversity in agriculture area. In this study, we investigated the effect of habitat heterogeneity integrated with different age of crop plant in urban agricultural landscape to the ant diversity. The field research was conducted in agricultural area in Carang Pulang Village, Dramaga, Bogor. In around 6 ha area of rice field, grouped into four blocks which each block has different habitat condition and age of rice plant. In bunds of each block were put six pitfall traps with minimum distance 20 meter from each other. Ants were collected weekly from 6 until 12 weeks after planting to standardize the bunds condition. In total 22 species from 4 subfamilies of ants were recorded from this research. Iridomyrmex sp.01 and Odontoponera sp.01 are the common species which always found in each block and in different age of rice plant. There are no correlation between the distance of pitfall traps and similarity of ant species. In addition, habitat conditions surrounding rice field (block) significantly effect to the ant diversity. However, age of rice plant have no effect to the ant diversity.

A study on diversity and abundance of grasshopper and its relatives (Orthoptera) was conducted at two mountainous rainforest ecosystems (Mounts Kendeng and Botol) of Gunung Halimun-Salak National Park. A hundred meters of a line transect was used to sample and set up several insect traps (yellow pan, malaise, pit fall, bait pit fall, sweep net, and light traps), and insect sweepings as well. The light traps were set up at about fifty meters distance from the end of the sampling sites. A total individual collected by traps was combined on every comparable sampling site. Total individuals of the Orthoptera captured were 414; consisted of 25 species of 9 families. Both species diversity and number of families were higher at Mount Kendeng rather than Mount Botol. Number of species of each family usually similar except on family of Grillidae was much higher at Mount Kendeng. Species belong to Phasmidae was not recorded at Mount Kendeng, while species belong to both families of Gryllotalpidae and Tettigonidae were not captured at Mount Botol as well. Overal there was a difference in the species richness at each between. Shannon Diversity Index (H’) and evenness (E) were higher at Mount Kendeng (2.44 and 0.81) rather than Mount Botol (1.80 and 0.66). Similarity Index of Jaccard (Cj) and Sorenson (Cn) of both localities were similar (0.40 and 0.32). Herbivores were most dominant at both localities (Phasmidae, Tetrigidae, Acrididae, Gryllidae, dan Gryllotalpidae), followed by omnivores (Blattidae), scavenger (Gryllacrididae), and predator (Mantidae).

The study aims to determine the presence of pests and natural enemies on soybean plants and to study the effect of insecticides on the diversity. Methods for observation of insects was done by using different type of traps i.e. yellow pan trap, pitfall trap, light trap, sweeping net and direct observation (visual). The presence of pests and natural enemies of soybean plants on plots without insecticide was lower than on the plots that was treated with insecticide. Composition of the population of pests found in soybean plots that were not treated with insecticide were dominated by Aphis sp. followed by Phaedonia inclusa, Riptortus linearis, Nezara viridula and Ophiomyia phaseoli. Composition of the population of natural enemies (predators) found in soybean cropps that were not treated with insecticide was family Coccinellidae followed by Syrphidae, Chrysopidae, Mantidae and Oxyopidae. The highest composition of natural enemies (parasites) found in treated and untreated soybean plots were family Braconidae then followed by family Ichneumonidae.

Currently, most cockroach control in urban environment relies on bait application. Aversion of some commercial bait by cockroach cause failure to control cockroach problems. Developing local bait can improve this situation. This research was aimed to find proper combination of some cockroach diet to be formulated in effective bait. Research was conducted in Department of Plant Protection, Bogor Agricultural University, since November 2007-March 2008. Combination of peanut butter, chicken egg, and strawberry jam seem to be a candidate of effective bait for local cockroach.
