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) served as the control. Each strain was tested for resistance to the two insecticides. 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 (RR<sub>50</sub> = 2880), and the lowest was in the JKT strain (RR<sub>50</sub> = 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 (RR<sub>50</sub> = 15.5) and the SBY strain had the lowest (RR<sub>50</sub> = 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.</p> Sri Yusmalinar Tjandra Anggraeni Ramadhani Putra Putra Ashari Zain M.

However, one major challenge in organic waste management in Indonesia is the limited space to manage the wastes at waste collection centers. This condition increases the number of wastes to be converted (consumed) by larvae of soldier fly. In this study, the condition was imitated in the laboratory where larvae were individually fed with a large number of wastes. Larvae were divided into 4 groups and were fed with 200, 300, 400, and 500 mg/larva/day of rotten vegetable waste (Pakcoy) and were replicated 3 times. Variables observed during the study were the growth rate, consumption capability, level of waste reduction (waste reduction index, WRI), consumption efficiency (efficiency of conversion of digested-feed, ECD), the weight of harvested biomass, and protein content of larvae, pupae, and adults. The results showed that there was no significant correlation between the weight of harvested biomass and the amount of substrate provided to larvae (one-way ANOVA, P &gt; 0.05). The increasing amount of substrate reduced the efficiency of waste reduction and consumption (one-way ANOVA, P &lt; 0.05). This study also showed that the possible upper limit of consumption capability of larvae was 400 mg/larva/day. On the other hand, the increasing amount of substrate increased the protein content of biomass of each developmental stage. </p> Agus Dana Permana Ramadhani Eka Putra Raeka Okata Soebakti Ida Kinasih Copyright (c) 2021 Agus Dana Permana, Ramadhani Eka Putra, Raeka Okata Soebakti, Ida Kinasi https://creativecommons.org/licenses/by/4.0 2021-12-21 2021-12-21 18 3 170 170 10.5994/jei.18.3.170 Biological activities and chemical composition of Mentha piperita and Syzygium aromaticum essential oil fractions against cowpea weevil, Callosobruchus maculatus (Fabricius) (Coleoptera: Bruchidae) http://jurnal.pei-pusat.org/index.php/jei/article/view/610 <p><em>Callosobruchus maculatus</em> (Fabricius) is one of the major, common, pests of stored grains as it causes quantitative and qualitative losses in legume crops. This research sought to find the most active fraction in <em>Mentha piperita</em> and <em>Syzygium aromaticum</em> essential oils, to evaluate bioactivity of those crude essential oils and active fractions against <em>C. maculatus</em>, and to identify the compounds contained in the active fraction. The essential oils were fractionated using three solvents, namely <em>n</em>-hexane, ethyl acetate, and methanol. The <em>n</em>-hexane fraction was identified as the active fraction, causing mortality, oviposition deterrence, and ovicidal effects. In fumigation chambers, LD<sub>95</sub> values of <em>M. piperita </em>(Mnf) and <em>S. aromaticum n</em>-hexane fractions (Snf) were 0.045 ml/l and 0.057 ml/l respectively. ED<sub>50 </sub>values for oviposition deterrence were 0.016 ml/l for Mnf and 0.022 ml/l for Snf. ED<sub>50</sub> value of ovicidal effects for Mnf- and Snf-treated eggs were 0.014 ml/l for both fractions. GC-MS analysis showed 8 dominant compounds in Mnf and 5 dominant compounds in Snf. Overall it is concluded that Mnf and Snf oils have effective biological activities against stored pest <em>C. maculatus</em> and have potential to be considered as alternatives to synthetic insecticides.</p> Kay Khine Myint Idham Sakti Harahap Dadang Dadang Copyright (c) 2021 Kay Khine Myint, Idham Sakti Harahap, Dadang https://creativecommons.org/licenses/by/4.0 2021-12-23 2021-12-23 18 3 182 182 10.5994/jei.18.3.182 The effectiveness of clove oil, its fractions, and clove oil-based fumigant tablet formulations, against Tribolium castaneum (Herbst) http://jurnal.pei-pusat.org/index.php/jei/article/view/585 <p>Indonesia has seen an increase and widespread reports of resistance among stored-product insect pests to phosphine. The use of <em>Syzigium aromaticum </em>(clove oil) as an alternative fumigant may be a useful strategy to control infestation by phosphine-resistant varieties of stored-product insects. The objective of this study was to examine the effectiveness of whole (unfractionated) clove oil as well as its component fractions as a fumigant and repellent against the red flour beetle (<em>Tribolium castaneum</em> (Herbst)), and to develop a simple fumigant formulation for this purpose. The experimental design used to test the effectiveness of clove oil and its fractionation was a completely randomized design (CRD). Meanwhile, testing the effectiveness of tablet formulations was carried out by factorial CRD. Fumigation test results gave LD<sub>50 </sub>and LD<sub>95 </sub>values of 0.234 and 1.142 ml/l respectively, for crude clove oil used in a fumigation chamber against <em>T. castaneum</em>. An <em>n</em>-hexane fraction of clove oil tested under the same conditions was more lethal, causing 95% mortality of <em>T. castaneum</em> at the dose of 0.801 ml/l during fumigation. Finally, tablets containing a set proportion of clove oil and naphthalene (1:1) reached LD<sub>91</sub> against <em>T. castaneum</em> after 7 days’ fumigation.</p> Trijanti Anughrahiyaharti Widinni Asnan Sri Widayanti Idham Sakti Harahap Herni Widhisatuti Copyright (c) 2021 Trijanti Anughrahiyaharti Widinni Asnan, Sri Widayanti, Idham Sakti Harahap, Herni Widhisatuti https://creativecommons.org/licenses/by/4.0 2021-12-23 2021-12-23 18 3 191 191 10.5994/jei.18.3.191 Tanggap fungsional predator Menochilus sexmaculatus (Fabricius) dan Micraspis lineata (Thunberg) (Coleoptera: Coccinellidae) terhadap kutukebul Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) dan kutudaun Myzus persicae (Sulzer) (Hemiptera: Aphididae) http://jurnal.pei-pusat.org/index.php/jei/article/view/608 <p>The whitefly, <em>Bemisia tabaci</em> (Gennadius) and the aphid, <em>Myzus persicae</em> (Sulzer) are important pests in tomato and chilli pepper. These pests directly attack and as a viral vector can decrease the production of tomato and chili pepper. <em>Menochilus sexmaculatus</em> (Fabricius) and <em>Micraspis lineata</em> (Thunberg) are predator beetles of <em>B. tabaci</em> and <em>M. persicae</em>. This study aimed to know the potential predation of <em>M. sexmaculatus </em>and <em>M. lineata</em> as a predator of <em>B. tabaci</em> and <em>M. persicae</em>. Completely randomized factorial design using 2 factors consist of type and density of prey with 3 replicates used in this study. The potency of predatory coccinellidae as predator of <em>B. tabaci</em> and <em>M. persicae</em> was evaluated in 2 observations, i.e. predation and functional response assay. Based on logistic regression analysis, both of <em>M. sexmaculatus </em>and <em>M. lineata</em> showed characteristic of type I functional, this means that the higher density of prey, the ability and predation rate of <em>M. sexmaculatus </em>and <em>M. lineata</em> were also increased. The predator <em>M. sexmaculatus </em>and <em>M. lineata</em> were more effective to control <em>M. persicae</em> than <em>B. tabaci</em>. <em>M. sexmaculatus</em> was the effective predator to control adult of <em>M. persicae</em>.</p> Purnama Hidayat Van Basten Tambunan Keisha Disa Putirama Copyright (c) 2021 Purnama Hidayat, Van Basten Tambunan, Keisha Disa Putirama https://creativecommons.org/licenses/by/4.0 2021-12-21 2021-12-21 18 3 199 199 10.5994/jei.18.3.199 Kepadatan populasi dan waktu efektif pelepasan tungau predator Neoseiulus longispinosus Evans untuk pengendalian Tetranychus kanzawai Kishida http://jurnal.pei-pusat.org/index.php/jei/article/view/681 <p>Kanzawa spider mite, <em>Tetranychus kanzawai</em> Kishida (Tetranychidae) is one of the most important pest mite in Indonesia. This mite is known as the pest of many crops, including cassava. <em>Neoseiulus longispinosus</em> 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 <em>T. kanzawai</em>. The aim of this research is to elucidate the effective density and release time of <em>N. longispinosus</em> to control <em>T. kanzawai</em> on cassava. The research was conducted in the greenhouse, using cassava of Mentega cultivar. <em>T. kanzawai</em> were introduced into the cassava plants two weeks after planting, with density 5 female adults/plants. <em>N. longispinosus</em> were introduced 1, 2, and 3 weeks after <em>T. kanzawai</em> introduction with predator:prey ratio of 0:5, 1:5, 2:5, dan 3:5, respectively. Population of <em>T. kanzawai</em> and <em>N. longispinosus, </em>and also plant damage were observed at 6 weeks after planting. <em>N. longispinosus</em> could suppress <em>T. kanzawai</em> population and the highest suppression occurred at the interaction between 3:5 ratio and the release time at one week after <em>T. kanzawai</em> infestation. There was no significant effect of <em>N. longispinosus</em> release at various release ratio and time on attack intensity of <em>T. kanzawai</em>.</p> Nhyra Kamala Putri Ali Nurmansyah Sugeng Santoso Copyright (c) 2021 Nhyra Kamala Putri, Ali Nurmansyah, Sugeng Santoso https://creativecommons.org/licenses/by/4.0 2021-12-21 2021-12-21 18 3 207 207 10.5994/jei.18.3.207 Issue Information http://jurnal.pei-pusat.org/index.php/jei/article/view/714 <p>No abstract is available for this article.</p> Editors Copyright (c) 2021 Editors https://creativecommons.org/licenses/by/4.0 2022-01-11 2022-01-11 18 3 i i 10.5994/jei.18.3.i
