The effect of intercropping chili with cabbage on pests and plant disease in Kerinjing Village Pagar Alam city. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp.101-113. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Red chili (Capsicum annuum) belongs to the family Solanaceae and is one of the vegetable commodities that has many benefits, high economic value. The aim of this field practice is to find out the difference in intensity of pest and disease attacks on intercropping and monoculture chili plants. This field practice was carried out in Kerinjing Village, Dempo Utara District, Kota Pagar Alam, South Sumatra. The reseach uses the case method by deliberate sampling in a field by counting the number of mounds in the field and determining the sample on the mound to be observed. On the two fields that were observed were found pests and diseases that attacked the chili plants namely mandibular pests and curly diseases, yellow disease and leaf spot disease. The average intensity of mandibular pest attacks on monocultures is 2.7% while on intercropping is 11.12%. The mean intensity of attacks of curly diseases was 33.87% in monocultures and 22.35 in intercropping. In jaundice, the mean intensity of attack was 14.87% in monoculture land and 8.25% in intercropping land while the mean intensity of spotting was 5.67% in monoculture land and 1.30% in intercropping land. From the observations that have been made that there is no significant difference between monoculture land and intercropping land for pests and diseases of chili plants. Weather affects the attack of pests and diseases on both fields, where dry weather affects the spread of disease-causing vectors so that the intensity of the attacks is higher. And also the use of crop rotation that is not right also exacerbates the level of pest and disease attacks on chili plants.

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The cultivation of vegetable crops is very much practiced by farmers both in the highlands and in the lowlands. In the cultivation of vegetables, pests and diseases cannot be separated. Pests that attack cucumber plants can be detrimental both in quality and quantity. The purpose of this study was to determine the insect pests that attack cucumber plants. Observations were made by comparing 2 cucumber fields. The comparison of the 2 fields was then carried out using the t test method. The results of observations on cucumber plants in the field were 4 species of insect pests that attack cucumber plants. Insects that attack cucumber plants consist of Diaphania sp., Aulacophora similis, Bemisia tabaci and Liriomyza sp.. The population of insect pests was found only 3 species based on visual observation and the intensity of pest attacks on cucumber plants was found to be 4 species of insect pests that attack these plants. In the t test results on insect populations, the species of Bemisia tabaci were significantly different in land 1 and land 2, while Diaphania sp. And A. Similis is not real different. The intensity of insect pests of Diaphania sp., Aulacophora similis and Liriomyza sp. Unreal different. However, the intensity of the Bemisia Tabaci attack was significantly different. The intensity of insect pests attack on land 1 was 44.76%, while on land 2 was 42.97%. Cultivation of cucumber with technical culture affects insect pests and the intensity of pest attacks.

Pujiastuti Y, SHK Suparman, Sulistyani DP. 2021. Patogenicity of entomopathogenic Bacillus thuringiensis isolated from Spodoptera litura against Plutella xylostella larvae (Lepidoptera:Plutellidae). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang  20 Oktober 2021. pp. 621-627. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Diamondback moth, Plutella xylostella is an important insect pest on plants belong to Brassicaceae family. Symptoms of attack is hollow leaves and leave dirt on them. If it is not controlled, the yield loss can reach 80%. Control by using biological agents entomopathogenic bacteria Bacillus thuringiensis may be used to reduce the population of P. xylostella. The purpose of research was to study the pathogenicity of B. thuringiensis isolated from cadaver of  Spodoptera litura against P. xylostella larvae in the laboratory. The treatments were two isolates of B. thuringiensis encoded  SlBt01 and SLBt03. The experiment was designed with a completely randomized design  (CRD) separated between isolates. The treatment consisted of 5 treatments (including control) spore density and 5 replications. Observations were mortality rate and time of death of the test larvae. Results showed the highest mortality was in isolate SlBT01 (61.73%)  and in isolate SlBt03 (56.66%). The lowest LT50 values of isolates SlBt01 and SLBt03 were 9.78 days and 9.14 days, respectively. Symptoms of infection in Plutella larvae are changes in body color and eventually die with symptoms of wet rot.

Inventory of insect insfesting chili  cultivation in sub district Air Salek, district Banyuasin, In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Inventory of Insect Infesting  Chili Cultivation in Sub District Air Salek, District Banyuasin Capsicum annuum L is one of the important horticultural crops cultivated in Indonesia and has high economic value. Chili plant is never been free from the associated insect activity. This field practice aims to find out the species species and insect population in the red chili crop. The field practice has been carried out at the farmers' chilli crop in  Sub District Air Salek, Banyuasin Regency. Insect identification was carried out at the Entomology Laboratory of Plant Pests and Diseases at the Faculty of Agriculture, Sriwijaya University. The implementation was carried out by direct observation using the census method by applying purposive sampling technique and using steiner trap fruit flies. The results showed that the populations of fruit fly in the first land, second and third fields was different for each observation. The fruit flies found were two species i.e. Bactrocera carambolae and Bactrocera umbrosa. There are several insects associated with chili plants, namely Coccineilla transversalis, Menochillus sexmaculatus, Micraspis discolor, Micraspis frenata, Aphis gossypii, Spodoptera litura and Altica cyanae. The number of insect populations in a plant is influenced by biotic and abiotic factors. Whether it's from the condition of the plants around or by the application of pesticides in the chili area.
