Oktaviani, O. (2023). Identification of insects associated with orange plants Citrus sinensis L. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 464-471).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Orange plant Citrus sinensis L. is a fruit that is widely cultivated in the area of South Sumatra. Productivity of orange plants is still relatively low because of the many disturbances encountered. The main disturbance in orange plants today is a disruption in their cultivation practices. Pests of citrus plants can cause farmers difficulties in getting maximum results. Investigating the species of pest attacking orange plants is important to determine what steps to take. The aimed of the research was identified insect pests and attack symptoms in the orange plant C. sinensis at the Sriwijaya University Agrotech Training Center (ATC), Ogan Ilir, South Sumatra. Research is carried out by survey methods. Catching and observing insect pests was done once a week for ± 2 months. The results of the research state that pest insects obtained in the orange plant C. sinensis are Blattella vaga, Bothrogonia addita, Cletus punctiger, Diaphorina citri, Hypomeces squamosus, Leptoglossus gonagra, Nezara viridula, Planococcus citri, Rhynchocoris longirostris, and Toxoptera aurantii. The species that dominates pests in the orange plant C. sinensis is the Rhynchocoris longirostris. It can be concluded that the insect that is known to damage orange plants C. sinensis L. is the order of the hemiptera and the spiny green ladybug species R. longirostris. This ladybug saves the eggs in leaves with an amount of 9 to 14 eggs. Ladybug eggs will hatch for ± 5-8 days after being placed. The spent cycle consists of eggs, five instars, nymphs and adults.

Nabila, A., Herlinda, S., Yulistin, E., Setyawati, A., Oktaviani, O., Anggraini, E., Yudanto, M. R. P. S., Chandra, F. A., Raffi, M., Az Zahra, A. D., Sari, D. M. (2024). population and storage pest species from three local markets with various roofs, floors, and ventilations in Sub-district of Alang-Alang Lebar and Sukarame, Palembang South Sumatera. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 679–689). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Storage insects provide a substantial risk to food spoiling, potentially resulting in a considerable reduction of up to 82.5% in food preservation. Ventilation is essential to avert harm caused by storage insect infestations. This study aimed to identify species and assess the population of storage pest insects in relation to the kind of ventilation in the Alang-Alang Lebar and Sukarame market's storage facilities. This study employed a direct collecting strategy for insects spotted on each food product commodity through handpicking, followed by the identification of each obtained sample. The identified bug species vary due to the diversity of dietary products. Species such Sitophilus oryzae and Tribolium castenum were predominant, alongside several others such as Cryptolestes ferrugineus, Carpophilus dimidiatus, Callosobruchus chinensis, Rhyzopertha dominica, and Oryzaephilus surinamensis. In the rice commodities market in Alang Alang Lebar District, the storage pest species S. oryzae was identified. S. oryzae is an insect pest that inflicts damage on stored rice. Sitophilus oryzae was found as the insect pest responsible for the majority of damage to stored rice. The peanut commodities in the Kebun Bunga Market and KM 5 Market comprised the species C. dimidiatus. C. dimidiatus was a significant pest that infests dry grains and fruits after harvest. The yield loss resulting from the assault of C. dimidiatus was quite substantial. Fermented peanut products were found as the primary target of C. dimidiatus. Seven species were identified in the storage with filtered ventilation. The pest insects infestation was deemed low due to the relatively small population, indicating the efficacy of both natural and filtered ventilation systems.

Population and storage pest species from two local markets with various structure and sanitation in sub-district of 7 Ulu and Plaju, South Sumatera. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 176–185). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Pest insects in storage are the primary cause of damage to food products in warehouses, leading to a decline in quality and storage outcomes. This study aimed to determine the diversity of insect pests in warehouses across two distinct marketplaces.This research used observational methods, utilizing purposive sampling and data gathering. Observations conducted across many marketplaces indicated that each species exhibited distinct population variability in every assessment of warehouse pest insects within market and warehouse regions. In the regions of 7 Ulu and Plaju, peanut commodities were identified to contain pest bug species such as Tribolium castaneum, Carpophilus dimidiatus, Callosobruchus chinensis, Cryptolestes ferrugineus, and Rhyzopertha dominica. The observations in the Plaju Market region identified pest insect species including Oryzaphilus surinamensis, Tribolium castaneum, Callosobruchus chinensis, Sitophilus oryzae, and C. ferrugineus. Observations at PT Bulog Palembang found pest insect species such as Tribolium castaneum and Sitophilus oryzae. The analysis of data from various surveyed markets indicated that the 7 Ulu market contained 5 species of peanut commodity warehouse pests, the Plaju market also had 5 species of peanut commodity warehouse pests, and the rice warehouse was infested with 2 types of rice commodity warehouse pests. resulting in a decline in both quality and quantity. According to the conducted survey, each market and warehouse should implement effective management of temperature, optimal humidity, appropriate lighting, and sanitation.
