Afifah, M., Nisa.N.A., Lisdiana, L., Suwandi, S., Muslim,A., Arsi, A., Gunawan, B., Irsan, C., & Pratama, R. (2023). Impact of biostimulants on the intensity of powderymildew disease in yellow pumpkin in Tanjung Pering Village, OganIlir Regency. In : Herlinda S et al.(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp.285-297).Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Pumpkin (Cucurbita moschata D.) can be used for various food preparations and contains high carotenoids. But now pumpkin production has decreased by 40% per year due to powdery mildew (Eryshipe cichoracearum). Symptoms of powdery mildew disease are marked white spots on the surface of the pumpkin leaves like flour. Biostimulants are believed to affect prevention of disease and pest attacks in the field. Purpose of this study was to determine the effect of biostimulants on the intensity of powdery mildew attacks on pumpkin and pest attacks. Research selected vegetative phase, observations made in the morning with the calculation of the percentage of powdery mildew disease using Natawigena formulation. There are 4 treatments, namely control, WB , RL and RL+WB , each treatment is 10 repetitions, 4x applications with a frequency of 1x a week, 5X observations.Results of the 2nd week the intensity of the disease increased due to rain after application with moist environmental conditions that support the growth of fungi. The effect of the 3 biostimulant treatments, can reduce the intensity of powdery mildew on pumpkin, was proven on the 3rd to 5th week, which is according to the data % severity of powdery mildew disease always decreases with a percentage of control that continues to increase. The percentage of influence of the greatest effectiveness in the treatment of WB, which is 95% powdery mildew and 2% Aulachopora similis pest control. In the application should see the weather conditions, so that the biostimulant applied can be optimally affected.

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 742-748). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Citrus plants (Citrus sp.) are horticultural crops, and fruit commodities from the Rutaceae family. The presence of weeds around citrus plants provides an alternative host for other insects and attracts natural enemies of citrus pests. This research was conducted to find out what insects were found in weeds around citrus plants in Ogan Komering Ilir Regency, South Sumatra, Indonesia. The sampling method used in this research was the purposive sampling method. Observations were carried out from June to October 2023 in Ogan Komering Ilir Regency, South Sumatra, Indonesia. The results of observations showed that in the weeds around the citrus plants, 4 species of insects were found belonging to 3 families and 3 orders. The 4 species are Monomorium minimum, Oecophylla smaragdina, Dysdercus cingulatus, Oxya sp. The most frequently found species was M. minimum from the Formicidae family with a total of 846 individuals and the fewest are Oxya sp. (Orthoptera: Acrididae) with 6 individuals.

(pp. 731–742).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).There are many factors that prevent Indonesia from exporting mustard fruits to other countries, one of which is that mustard fruits spoil quickly. Mustard fruit is an agricultural product that cannot be stored for a long time, so it is at high risk in marketing. This field practice aimed to identify insect species found on mustard fruit in the ATC (Agriculture Training Center) field and in places overgrown with mustard fruit inside the Sriwijaya University Indralaya campus. This field practice uses direct survey methods and insect identification using the Google Picture Insect application. The results showed that 4 different orders and 7 different families were found. The insect orders are Diptera, Hemiptera, Hymenoptera, and Lepidoptera. For the Diptera order, 2 families were found, namely D. melanogaster from the Drosophilidae family and B. dorsalis from the Tephritidae family. The Lepidoptera order also found 2 families, namely O. subnotata from the Erebidae family and L. omnivora from the Psychidae family. As for the other 3 orders, each insect order only found one family. Of all the insects identified, C. pennsylvanicus and P. manihot were the two most common insect species found on the three observed sawo plants. The number of fruit flies found on sawo plants was 83, the intensity of attack on sawo fruits was up to 29.61%. Based on the results found there are 7 species of insects and 1 species of spiders that are found to live in mustard plants. The 7 insect species are Drosophila melanogaster, Bactrocera dorsalis, Phenacoccus manihot, Tartessus ferrugineus, Camponotus pennsylvanicus, Orvasca subnotata, Liothula Omnivora, and the spider species found is Telemonia dimidiate. The ant species Camponotus pennsylvanicus can be found in all parts of the sawo plant. Insect species in the ATC field included B. dorsalis, P. manihot, C. pennsylvanicus, and O. subnotata. And one spider species found in the ATC field is the spider species T. dimidiata. Meanwhile, at least 3 insect species were found in fisip fruit plantations. Insect species found in fisip fruit plantations are D. melanogster, T. ferrugineus, and L. omnivora.

Sugiarto, M.H., Irsan, C., Warman, A., Laila, M.R., Nuraini, F., Putri, O.A. (2024).Phytophagous and Entomophagous insects on bitter gourd (Momordica charantia L) plants in North Indralaya District, Ogan Ilir Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 843–853). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Phytophagous insects are plant-eating insects or what are usually called herbivores. These phytophagous insects are referred to as pests if their eating behavior on plants causes economic losses. Meanwhile, predatory insects or entomophages are a group of natural enemies that are very important in helping reduce pest populations. This research aims to identify and determine insect species that live on plants or around plants and their role on plants and other insect species. Research was conducted on 2 vegetative and generative bitter melon fields among farmers in North Indralaya District, Ogan Ilir Regency, South Sumatra Province in September 2021. The observation method was carried out using 2 traps, namely the pan trap and the pitfall trap. This observation was carried out every morning at a distance of 12 hours for pan traps and 24 hours for pitfall traps within 1 week. Observations on bitter melon plants show that arthropod species use pan traps. The results obtained were 7 orders, 16 families and 17 species of arthropods on bitter melon plants which were successfully identified using pan traps and 6 orders and 9 families and 8 species of arthropods which were successfully identified using pitfall traps.

Umayya, L.N., Irsan, C., Mulawarman, M., Shobiha, S.N., Fani, G., Apriyani, M., Aulia, H., Mirsya, S.A. (2024). Insects found on duku plants (Lansium domesticum Corr) in Muara Enim Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembangg 21 Oktober 2024. (pp. 212–220). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Cultivation of duku plants has obstacles such as applying of low cultivation technology and interference from Plant Disease Organisms (OPT). Therefore, we need to know the identification of pests that attack duku plants in the area to determine what pest species are causing damage to duku plants. The method used is direct observation and interviews. The results of observations carried out in farmers' duku gardens in Kepur Village, Muara Enim Regency show that insects that have the potential to become pests consist of 6 species, such as red caterpillars, fruit flies, ladybugs, tree termites, plutellidae larvae, and dompolan lice, in contrast other pests attack duku plants are bats and ants. Red caterpillars attack the skin on duku stems, termites attack the lower stems, dompolan lice attack the fluid on the leaves, ladybugs attack young fruit and fruit flies attack the inside of the fruit. Production can be reduced by up to 50-100 kg/stem due to pest attacks on duku plants. Dompolan lice attack duku plants which have a symbiotic relationship with ants. From this description, it was found that tree termite pests are the pests with the highest population and most insects attack the stems of plants. To develop duku production, further research is needed to control pests on duku plants.

(pp. 127–134).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Grasshoppers are animals that belong to the insect class. The diversity of grasshoppers can influence the diversity of parasitoids and predators in an ecosystem. Environmental factors are factors that influence the presence of grasshoppers in a habitat. The aimed of  this research was to the morphology of stick grasshoppers (Eurycnema goliath) kept on Red Shoot Plants (Myrtaceae) is to observe and describe the morphology of grasshoppers, including body structure, color and size related to their adaptations. This research also aims to assess the interaction of grasshoppers with red shoot plants, such as food preferences and their impact on plant growth. The method used in this research is a survey method by observing and directly measuring the length of the stick grasshopper (E. goliath). The data obtained from these observations are presented in the form of tables and pictures and the results of the observations obtained are described. The results obtained from this research are to understand the life cycle of stick grasshoppers starting from eggs, nymphs, and then imago. The stick mantis eggs are dropped to the ground by the female imago to hatch among the leaves. When entering the nymph phase, the stick grasshopper begins to climb up the stem of the plant that is its habitat. In the first instar nymph phase, the stick grasshopper is whitish brown, then in the second instar the color changes to light brown. The third and fourth instar nymph phases show a change in color to brown, while in the fifth instar, the stick grasshopper is greenish brown. The imago phase is marked by a color change to green. This research shows that keeping stick grasshoppers on plants of the Myrtaceae family helps understand their morphology and type of reproduction. This animal is included in the group that undergoes incomplete metamorphosis.
