Cocoa (Theobroma cacao) is one of the important commodities in Indonesia. The quality of cocoa beans has decreased during storage, one of which is due to the attack of Araecerus fasciculatus (De Geer). This pest attack can be overcome by fumigation that is safe for the environment through the use of essential oil. The study aimed to examine the mortality and repellent effects of kaffir lime leaves essential oil (KLLEO) to A. fasciculatus and to analyze the compound content of active fraction KLLEO using GC-MS. Research stages included maintenance and insect rearing, toxicity and repellency tests, fractionation, and analysis of active fraction compounds of essential oils. The study was designed using CRD with 6 treatments and 4 replications. The n-hexane fraction of KLLEO caused the highest mortality of A. fasciculatus adults after 72 hours of fumigation. The LD50 and LD95 values of the n-hexane fraction of KLLEO were 0.30 and 1.66 ml/l air, respectively. The dose at 1 ml/l air caused the highest mortality of A. fasciculatus adult by 73.75%. Examine using an olfactometer, KLLEO has high repellency against adult A. fasciculatus with the value of the repellency index reaching 100% at 1 ml/l air. The most dominant compound in the n-hexane fraction of KLLEO was the citronellal. Therefore, the KLLEO has some potential to be expanded as a botanical fumigant towards A. fasciculatus.

Water-strider Ptilomera dromas Breddin (Gerridae: Hemiptera) is an aquatic insect that is commonly found in various waters, such as rivers, ponds, and lakes. The purpose of this research was to study the abundance of P. dromas in Ciliwung river in relation to its water quality. The abundance of P. dromas was surveyed at five stations, i.e. Cilember, Cijulang, Gadog, Katulampa, and Sempur stations. Environmental parameters measured were water temperature, air temperature, pH, water flow, biological oxygen demand (BOD), dissolved oxygen (DO), free CO2 level, nitrogen total, water hardness, and total suspended solid (TSS). The relationship of P. dromas abundance with environment parameters was analyzed by using general linear model (GLM). Results showed that the highest abundance of P. dromas was found in Gadog station, followed by Cilember, Katulampa, and Cijulang stations. The population of P. dromas was not found in Sempur station, which might be related to the presence of Katulampa weir that acts as physical barrier and due to high BOD and TSS values. Based on GLM analysis, water hardness and pH were correlated positively with abundance of P. dromas. The existence of P. dromas in the upstream stations is linked to the high water quality and low pollution of waters.

The level of contaminants in the land can be reduced by remediation. Remediation allows to destroy or makes contaminants into harmless using natural biological activities (bioremediation). Land conditions before and after bioremediation treatment is uses some kind of arthropods land as an indicator of soil fertility. This study aims to assess the factors affect diversity, compare the structural similarity, and species composition of soil arthropods as bioindicators of the recovery of soil biological properties in chili cultivation. Soil arthropod sampling was carried out on chili farmers’ fields with 5 bioremediation treatments in Sangir Tengah Village, Kayu Aro District, Kerinci Regency, Jambi Province with the pitfall trap method that was installed for 2 nights. The bioremediation treatments were control (without bioremediation), and 4 bioremediation treatments (trichocompos 10 tons/ha, trichocompos + bagasse biochar at a dose of 2 tons/ha, trichocompos + corncob biochar at a dose of 2 tons/ha, and trichocompos + rice husk biochar at a dose of 2 tons/ha. The results showed that there were 9,712 individuals belonging to 10 orders and 28 species of soil arthropods. The diversity of soil arthropods in the bioremediation treatment showed significant differences (R = 0.3953; P < 0.001). The Shannon-Wiener diversity index was highest in the control land as well as the evenness index (E) which means that the bioremediation treatment had no effect on the diversity of soil arthropods. Bioremediation treatment on chili fields did not show an increase in the number of orders and species.

Kanzawa spider mite, Tetranychus kanzawai Kishida (Tetranychidae) is one of the most important pest mite in Indonesia. This mite is known as the pest of many crops, including cassava. Neoseiulus longispinosus Evans (Phytoseiidae) is a predatory mite commonly found on plant infested by kanzawa spider mite. This predatory mite has high potential to be developed as biological control agent of T. kanzawai. The aim of this research is to elucidate the effective density and release time of N. longispinosus to control T. kanzawai on cassava. The research was conducted in the greenhouse, using cassava of Mentega cultivar. T. kanzawai were introduced into the cassava plants two weeks after planting, with density 5 female adults/plants. N. longispinosus were introduced 1, 2, and 3 weeks after T. kanzawai introduction with predator:prey ratio of 0:5, 1:5, 2:5, dan 3:5, respectively. Population of T. kanzawai and N. longispinosus, and also plant damage were observed at 6 weeks after planting. N. longispinosus could suppress T. kanzawai population and the highest suppression occurred at the interaction between 3:5 ratio and the release time at one week after T. kanzawai infestation. There was no significant effect of N. longispinosus release at various release ratio and time on attack intensity of T. kanzawai.

N. longispinosus could suppress T. kanzawai population and the highest suppression occurred at the interaction between 3:5 ratio and the release time at one week after T. kanzawai infestation. There was no significant effect of N. longispinosus release at various release ratio and time on attack intensity of T. kanzawai.","PeriodicalId":31609,"journal":{"name":"Jurnal Entomologi Indonesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41353169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A previous report has indicated that in many regions of Indonesia, populations of Musca domestica Linnaeus have shown very high resistance to permethrin and low resistance to imidacloprid. In this study, the resistance status to permethrin and imidacloprid was updated using a topical application and feeding bioassay. Six housefly strains originated from six highly populated cities in Indonesia, namely Serang (SRG), Jakarta (JKT), Bandung (BDG), Semarang (SMG), Yogyakarta (JOG), and Surabaya (SBY). A seventh strain (Danish Pest Infestation Laboratory (DPIL)) served as the control. Each strain was tested for resistance to the two insecticides. In addition, the rate of development of resistance to the two insecticides was measured over ten generations. The results indicated that all field strains showed very high resistance to permethrin. The highest resistance level recorded was in the SRG strain (RR50 = 2880), and the lowest was in the JKT strain (RR50 = 520). Repeated application of permethrin over ten generations increased the resistance level by about 2.7–32.73-fold as compared to the level of their respective parental populations. On the other hand, most strains showed low to moderate resistance to imidacloprid, in which the SRG strain had the highest resistance level (RR50 = 15.5) and the SBY strain had the lowest (RR50 = 2.0). Repeated application of imidacloprid over ten generations increased the resistance level by about 3.25–17.41-fold. The findings, which is the second report of housefly resistance in Indonesia since 2016, provide a crucial foundation for developing appropriate housefly integrated pest management strategies in highly populated areas in Indonesia.
