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.

Most of thrips from Thripidae family are pests on horticultural crops. To date, there are no records in the species richness of thrips in horticultural crops. The aim of the research is to conduct inventory on thrips spp diversity that are associated with horticultural crops in West Java. Sampling were done in several horticultural crops areas in Bogor, Cianjur, and Lembang (West Bandung). The identification process began with sample slide preparations along with the documentation of the character from each species. The identification was done mainly by using the identification program Oztrips and some other published identification keys. Identification key was built based on diagnosis characters of each species. The results found there were 15 species, that are Ceratothripoides brunneus, C. revelatus, Frankliniella intonsa, Megalurothrips typicus, M. usitatus, Scirtothrips dorsalis, Thrips aspinus, T. coloratus, T. hawaiiensis, T. javanicus, T. malloti, T. palmi, T. parvispinus, T. sumatrensis, and T. unispinus. T. aspinus and C. revelatus were new record for Indonesia.

This study was conducted to investigate flea infestation and Dipylidium caninum (Linnaeus 1758) infection on stray cat on Bogor Agricultural University Dramaga. Thirty stray cats were collected from various places around on Bogor Agricultural University Dramaga. The stray cats that showed clinical signs of pruritus and alopecia were collected purposively. The whole body was powdered by gamexan powder, after that the fleas were collected by manual and examined microscopically. The totals of 30 fecal stray cat samples collected and examined toward D. caninum used Mcmaster methode, flotation methode, and saw the existence of proglottid. The result of identification showed that there was found one species of flea, namely Ctenocephalides felis (Bouche 1835), while on faeces was not found D. caninum. Twenty one stray cats were infected by the flea with density average of fleas per cat was 3.8 ± 1.9 individual.

In this study, termite bait comprising pinewood of sawdust and a slow action insecticide, fipronil, was made and applied to control subterranean termite Macrotermes gilvus (Hagen) (Isoptera: Termitidae) in Bandung. Colony size was measured using capture-mark-release-recapture prior to the bait application, along with the measurement of wood consumption at each station. Colony foraging populations at all stations were estimated to be 77,951 termites, with mean wood consumption rates ranging from 0.02 to 6.16 g/station/day. Observation at 18 stations installed with bait consisted of 40 ppm fipronil mixed with pinewood sawdust showed that number of foraging activity termites was effectively reduced in 40 days. It is concluded that fipronil-treated pinewood sawdust bait is effective in controlling the population of foraging M. gilvus workers in 40 days.

Keefektifan ekstrak Piper retrofractum Vahl., Anonna squamosa L. dan Tephrosia vogelii Hook. serta campurannya terhadap imago kutu putih pepaya Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae) Trijanti A. Widinni Asnan; Dewi Sartiami; Ruly Anwar; Dadang Dadang

Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae) is one of the papaya insect pests that causes high economic loss. The major constraint in controling this pest with insecticides is the existence of wax layer covering the insect body.The objective of this research was to evaluate the effectiveness of Piper retrofractum (Pr), Anonna squamosa (As), and Tephrosia vogelii (Tv) extracts as well as their mixtures to control P. marginatus imago in the laboratory. Pr, As, and Tv extracts were tested separately and in extract mixtures against female P. marginatus by direct spray on the insect. Each treatment was observed at 24, 48, and 72 hours after treatment (HAT). Our result showed that at the LC95 – 72 HAT, Tv and As extracts were about three times more effective to P. marginatus than Pr extract. The effective concentration that causing around 95% mortality of P. marginatus are 1.250% (Tv), 1.482% (Pr), dan 0.469% (As). Extracts mixtures of Tv + As (2:1, w/w) and As + Ps (2 : 1, w/w) were about 1.67 times more effective than Tv + Pr (2:1, w/w) extracts mixtures. Based on combination index at 72 HST, extract mixtures of Tv + As and Tv + Pr had low sinergistic joint action, meanwhile As + Pr extract mixture had additive joint action. In addition, all the extracts treatments disturbed the formation of the wax coverings the eggs (egg sacs). Pr, As, and Tv extracts as well as their mixtures at certain extract comparison have the alternate potential to control the mealybug P. marginatus.

Spiders are the main predators in paddy ecosystem. Application of entomopathogenic fungus, such as Beauveria bassiana (Balsamo) is not expected to have any negative effect on spiders in the paddy field. This research was aimed to compare species composition, abundance, and species richness of spiders in ratoon paddy. The research was done on three hectares of rice fields that were treated with the following treatment, (i) 2 L/ha/application of liquid B. bassiana, (ii) 2 L/ha/application compost extract (without liquid B. bassiana), and (iii) a combination of liquid B. bassiana and compost extract with each using the same 2L/ha/application dose. The result of this research showed that B. bassiana bioinsecticide application did not affect the abundance and species richness of spiders in ratoon paddy. The treatments did not significantly affect species richness and abundance of the canopy-inhabiting spiders. The species richness and abundance of the soil-dwelling spiders on the paddy field applied by the bioinsecticide was not different from those without the bioinsecticide. The treatments did not effect species composition of the canopy-inhabiting and the soil-dwelling spiders. Application of B. bassiana bioinsecticide was not harmful for the spiders in the rice field.

Plant extracts have been known to cause physiological and biochemical interferences against insect, such as feeding inhibitor, food assimilation, and changes on activity of cytochrome b5 and cytochrome P450. This study was carried out to examine the effect of the extracts mixture of Tephrosia vogeliiand : Piper aduncum (1 : 5) on the physiology of Crocidolomia pavonana (F.) as well as extract of P. aduncum on biochemical of C. pavonana. The study showed that larvae of C. pavonana was experiencing a feeding inhibition until 94.82% after treated with extracts mixture on concentration 0.06% or equivalent to LC95. However, larvae treated with extracts mixture on LC25 and LC50 only experienced a relative growth disorders as a result of intrinsic toxicity of extracts mixture which enters into the body of insects. Insect adaptation to toxic plant compounds indicated by an increase in the digestibility of larvae approximately 11.11%. Furthermore, detoxification mechanism by larvae against active compounds of P. aduncum occured and shown by an increase of oxidative enzyme activity of cytochrome b5 and cytochrome P450, in in vivo and in vitro compared to control. This study provides an information about mode of action of extracts mixture of T. vogelii and P. aduncum (1 : 5) on larvae of C. pavonana and detoxification mechanism by larvae due to extract of P. aduncum
