Mahi Imam Mollahmahiimam@pstu.ac.bd<p>Brinjal shoot and fruit borer (BSFB) is a serious insect pest of brinjal, causing significant damage and yield loss in Bangladesh. Chemical insecticides having toxic effects are frequently applied to control this pest. The present study was conducted with two insecticides, emamectin benzoate and abamectin individually or in combination with plant-origin azadirachtin to combat BSFB. The insecticides were applied at 7-day intervals using a knapsack sprayer. Though all the insecticides control BSFB, emamectin benzoate 1% + azadirachtin and abamectin 1.8% + azadirachtin were found to be most effective, providing 89.34% and 81.55% shoot infestation reduction, 93.34% and 85.11% fruit infestation reduction (number basis), and 94.91% and 85.27% fruit infestation reduction (weight basis), respectively. The highest marketable yield was obtained from abamectin 1.2% + azadirachtin (2.32-ton ha<sup>-1</sup> harvest<sup>-1</sup>). The same treatment confirmed the highest gross yield (2.72-ton ha<sup>-1</sup> harvest<sup>-1</sup>). However, the highest individual weight of marketable fruit was obtained from abamectin 1.2% + azadirachtin (47.30 g). Therefore, emamectin benzoate 1% + azadirachtin and abamectin 1.8% + azadirachtin can be recommended for BSFB control, while abamectin 1.2% + azadirachtin is recommended for increasing fruit yield. However, further investigation is required.</p>2025-02-10T00:00:00+00:00Copyright (c) 2025 Md.

The goal of this 2-year study was to compare the abundance and species composition of native agrobiont lady beetles among habitats such as corn, winter grains, prairie, and arboreal tracts across three seasons (late spring, summer, and autumn) in eastern South Dakota, USA. Yellow sticky traps were used to sample a total of 797 individuals and 13 species of lady beetles. <em>Coleomegilla maculata lengi</em> Timberlake was the most abundant species and found predominantly in corn and arboreal habitats. <em>Hippodamia convergens</em> Guérin-Méneville was the second-most abundant species and found mainly in prairie and crop habitats. <em>Harmonia axyridis</em> (Pallas) was sampled only in 2023 in low numbers but preferred arboreal habitat to other habitats. <em>Hippodamia parenthesis</em> (Say) preferred winter grain and prairie habitats over corn and arboreal habitats. <em>Cycloneda munda</em> (Say) preferred corn to other habitats. This study was designed to include habitats that would optimize detection of <em>Hip. tredecimpunctata tibialis</em> Timberlake, which has declined in recent years, but it was not sampled from any of the habitats. Prospects are discussed for conserving native agrobiont lady beetles that prey on crop pests among habitats within agricultural landscapes in eastern South Dakota.</p>2024-11-28T00:00:00+00:00Copyright (c) 2024 Louis Hesler, Eric Beckendorfhttps://www.pagepressjournals.org/jear/article/view/13018Predatory ability of <i>Sycanus annulicornis</i> Dohrn. (Hemiptera: Reduviidae) on nettle caterpillar prey (<i>Setora nitens</i> Walker.) (Lepidoptera: Noctuidae) in the laboratory2025-02-10T10:43:15+00:00Rusli Rustamrusli.rustam@lecturer.unri.ac.idDwi Yuwanda Nasutiondwiyuwandanasution12@gmail.comYunandra Yunandrayunandra@lecturer.unri.ac.idMukhlis Ibrahimmukhlis.ibrahim77@gmail.com<p>The nettle caterpillar (<em>Setora nitens</em>) is a major pest affecting oil palm plants and is predominantly found in oil palm plantations in Riau. The predator <em>Sycanus annulicornis</em> Dohrn is a potential natural enemy for controlling <em>S. nitens</em>. This study aims to evaluate the predatory ability of <em>S. annulicornis</em> imago when preying on <em>S. nitens</em>. The research was conducted at the Plant Pest Laboratory, Faculty of Agriculture, Riau University, from March to July 2023. The experiment was designed using a completely randomized design method consisting of three treatments with seven replications. The treatments involved <em>S. annulicornis</em> imago [N1=one male imago, N2=one female imago, and N3=one pair of imago (male and female)], with observation parameters including first and second prey search time, prey handling time, predation ability, and total predation. Results showed that the handling time for one <em>S. nitens</em> by <em>S. annulicornis</em> ranged from 3.86 to 5.14 hours. The treatment involving one pair of <em>S. annulicornis</em> imago was the most effective, as it resulted in the fastest prey search times (0.79 minutes for the first prey and 0.71 minutes for the second prey), as well as the fastest prey handling time (3.86 hours), with a total predation rate of 100% for <em>S. nitens</em>.</p>2025-02-10T00:00:00+00:00Copyright (c) 2025 Rusli Rustam, Dwi Yuwanda Nasution, Yunandra Yunandra, Mukhlis Ibrahimhttps://www.pagepressjournals.org/jear/article/view/12635Fruit flies (Diptera: Teprithidae) and their parasitoid (Hymenoptera: Braconidae) species from registered snake fruit production during early rainy and dry seasons in the Special Region of Yogyakarta, Indonesia2024-11-26T14:50:33+00:00Oka Dwi Handaruokadwi86@mail.ugm.ac.idWitjaksono Witjaksonowitjaksono@ugm.ac.idDinta Dewi Arumwitjaksono@ugm.ac.idKuwat Triyanatriyana@ugm.ac.idSuputa Suputaputa@ugm.ac.id<p>Exportation of snake fruit from Indonesia to China, Australia, and New Zealand has been hindered due to fruit fly infestations (Diptera: Teprithidae). The goal of this study was to identify fruit flies and their parasitoid species from registered snake fruit productions in Turi, Sleman, that have reached packaging houses during early rainy and dry seasons. Fruit fly species were morphologically identified from collected rejected or damaged snake fruit. Parasitization was calculated by dividing the number of emerging parasitoid species by the total number of parasitoid and fruit fly individuals. The population of fruit flies and parasitoids was then compared to climatic data. Female fruit flies that emerged from snake fruit possessed spots on their front preapical femur, concluding that these species were <em>Bactrocera carambolae</em>. The average fruit fly that emerged per fruit was 16.5 individuals. Only one parasitoid species emerged and possessed <em>notauli on mesonotum</em> that elongated to the center and petiole and longitudinal <em>metasomal tergum</em> 2, implying that this parasitoid species was <em>Fopius arisanus</em> with an average population of 5.71 individuals with a parasitization percentage of 26.86%. Results from this research concluded that the fruit fly species collected from registered snake fruit productions in Turi, Sleman, during the early rainy season and dry season was <em>Bactrocera carambolae</em> with a low parasitization level by <em>Fopius arisanus</em>. This parasitization level may be affected by fruit fly density and climatic factors, such as humidity and rainfall.</p>2024-11-26T00:00:00+00:00Copyright (c) 2024 Oka Dwi Handaru, Witjaksono Witjaksono, Dinta Dewi Arum, Kuwat Triyana, Suputa Suputa
