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.

Sibling species identification is very important in the understanding of malaria epidemiology. Morphological criteria are usually used in the identification of anopheline species, but this fails when sibling or cryptic species occur. Analysis by PCR-RFLP of rDNA ITS2 is currently the most reliable and sensitive method for distinguishing between members of the Anopheles punctulatus group. The objective of this study was to investigate the effect of DMSO concentration on ITS2 amplification of An. farauti from the colony maintained at BATAN Jakarta using PCR-RFLP based on the rDNA ITS2. The results showed that the addition of 6 % and 7 % DMSO produced ITS2 amplification products in the size 750 bp. DMSO could be used in PCR to relieve secondary structures when amplifying high GC templates. Molecular identification of An. farauti is found to be Anopheles farauti sensu stricto.

There are approximately 1.4 million hectares of swampy area in South Sumatera, but only 12% of those are being used as farm and plantation. The purpose of this research was to investigate the similarity of arthropod community inhabiting swampy rice field and its surrounding area. This research was conducted in South Sumatera Province covering regency of Musi Banyuasin and Palembang. Four types of swampy area were selected from each location, i.e. rice field, thicket, bush, and swampy land inhabited by broad-leaf weeds. Pitfall trap used to collect arthropod and it installed at five different times. i.e. 15 days before rice planting, one month, two months, and three months after planting, and 15 days after harvest time. The result showed that relative abundance of predatory arthropod dwelling soil in rice field was 95.03%, and habitat surrounding rice field was 95.12–97.21%. The level of similarity of arthropod species between rice field ecosystem and its surrounding area ranged from 0.73 to 0.84. Thus, the surrounding area of rice field probably can be used as catchment area of predatory arthropod and other pests during planting season.

Bogor and its surrounding area is known as one of the region in West Java that has high diversity of horticultural plants that may have an affect on fruit fly diversity. Research on fruit fly diversity is not merely provide information on the species richness of fruit flys but also provide information on its distribution and dispersion. The aim of this research was to investigate the diversity and distribution of fruit flies species and their hosts in Bogor and its surrounding area. Fruit flies were collected from 119 sampling areas in Bogor Cianjur, Bekasi and Depok. Fruit flies were sampled using two methods, i.e. host rearing and trapping. Traps were modified from Lynfield traps and combined with two different attractants, i.e. metil eugenol (ME) and Cue lure (CL). We found 18 species of fruit flies collected from traps and 24 host plants. The result showed that distribution, diversity and abundance of fruit flies was influenced by the diversity of host plants.

Kanzawa spider mite (KSM), Tetranychus kanzawai Kishida (Acari: Tetranychidae) is an important pest on many crops in Indonesia. Generally, farmers use acaricide to control this mite, which may cause negative side effects. One of the alternative control methods is the use of predatory mite. This research was done to determine prey preference and functional response of predatory mite Neoseiulus californicus (Acari: Phytoseiidae) on several life stages of KSM. Experiments were conducted under laboratory conditions. N. californicus were supplied with nymphs and adults of KSM to know its preference. N. californicus were also supplied with KSM eggs at several densities to know its functional response. Adult females and deutonymphs of N. californicus preferred KSM eggs than nymphs as their prey. The number of eggs consumed by adult females and deutonymphs N. californicus increased with the increase of prey density. The number of eggs laid by adult females of N. californicus increased with the increase of prey density. Searching time of the predator became faster with the increase of prey density. N. californicus showed cannibalism under low density of prey.

This study was carried out on three soybean farms located in the Liverpool Plains Shire in New South Wales, Australia. The soybean farms were different in terms of pesticide type used. One of the soy crops was sprayed with broad spectrum synthetic pesticides (synthetic pyrethroids), one site of soy crop was sprayed with natural pyrethrum - an organically certified pesticide, and one of the soy crops was not treated with any pesticides. Arthropod samples were collected on three occasions at every site except in the third site of soy crops which was not treated with any pesticides. Samplings were done using sweep nets and beat sheets. There were no significant differences of community structure change between farms treated with different pesticide regimes (F2,5= 4.2599, P(perm)= 0.188), and no significant differences in arthropod species richness. The abundance of arthropods was significantly different for site treated with biopesticide and site treated with synthetic pyrethroids (G6 = 284.36, P <0.0001), non-sprayed site and site treated with synthetic pyrethroids (G6 = 2110, P < 0.0001), and non-sprayed site to site treated with biopesticide (G6 = 2027, P < 0.0001). The use of synthetic pesticides in agriculture has been found to suppress pests and beneficial arthropods, while the use of biopesticides or without pesticide, to some extent, may let beneficials thrive in the system and also may suppress pest arthropods.

Insect diversity and vegetation structure are two aspects that affect the reproduction of insectivorous birds. The objective of this study was to investigate the characteristics of the original habitat Lanius schach in Tanjungsari of particularly the type, composition of vegetation, and preference to insect sprey. Observation of vegetation and insects were conduct using a combination methods of the track and checkered line on the transect along the 10 km (ten observation points). Insect and tree species were counted on plot (20 m x 20 m), shrub (10 m x 10 m), bush (5 m x 5 m), and grass (2 m x 2 m). Vegetation analysis was used to calculate the structure and composition of vegetation, whereas Shannon diversity index was used for insect diversity. Prey test was conducted to determine the preferences of insectivore birds on insects. The composition of the vegetation species consists of 7 grasses, 20 bushes, 5 shrubs and 18 trees. The dominant species of vegetation based on highest important value index was Tectona grandis, Ipomoea sp., I. cylindrica, and Panicum brevifolium respectively. The highest diversity index of vegetation group were bush (2.430), tree (1.696), grass (1,680), and shrubs (1.364), respectively. Insect diversity index was 2.572 and grasshoppers (Orthoptera) was the most preferred prey by L. schach. Overall, the habitat of insectivore birds L. schach are dominated by T. grandis, and has high diversity of bush.
