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.

Farhan E, Famita D, Simbolon MS, Ningsih SR, Yusuf ZN, Irsan C.  2021. Identification of aphids on chili plants in Indralaya. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 530-536.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Chili (Capsicum frutescens sp.)is a type of plant organiting from the Americas. Chili plants in Indonesia are reported to have been attacked by many diseases caused by insect such as aphids. The research was conducted in Tanjung Pering, North Indralaya District, Ogan Ilir, and Indralaya Indah District , Indralaya District, Ogan Ilir District, South Sumatra. The purpose of this research was to indentify the characteristics of chilli crop  and to know the influence of the population of aphids on Chili with different location and treatment. The method used in making this scientific paper were literature study and observation. The results showed that the plants in Indralaya Indah location (land B) more pest aphids than in Tanjung Pering (land A). On land A there was pest of species aphids (Myzus persicae). On land B there were aphid pests of Aphis gossypii species, Myzus persiciae, and whitefly pest Bemisia tabacispecies. In conclusion, the presence oh whitefly population on land A is caused by the presence of papaya plants around the land. Aphid pests attack  many chili plants in land B because the amount of weeds is too high than in land A.

Suci IW, Zelika SA, Luzia AS, Wallingga R, Abdurrosyid MA, Irsan C. 2021. Parasitisation of Telenomus sp. on suppressing Spodoptera frugiperda's (Lepidoptera: Noctuidae) egg population on the maize plant. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 689-696. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Spodoptera frugiperda (Lepidoptera: Noctuidae) is a polyphagous pest which attack plantation plant, one of them is maize plant (Zea mays). Attact aftermath this pest which was mentioned as Fall Armyworm which can injured the farmer products cause of its behaviour which attack growing point plant until can trigger failure of leaf preening. One of how to control S. frugiperda pest is by relying on natural enemic, which is parasitoid. Telenomus sp. is the one of many species of egg parasitoids of Fall Armyworm S. frugiperda, which is used most of the biodegradable control to reduce specific pest attacks on maize plants. The role of parasitoid is also important in suppressing host populations because they are specific and easier to breed than other natural enemies such as predators and fungi. The aimed of this scientific papers was to knew the potential and level of parasitism of Telenomus sp. on S. frugiperda’s egg population. The method used for this scientific papers was studied of literature from book and scientific journal on internet. Based on studied of literature, the parasitic rate of S. frugiperda’s eggs when the female imago of Telenomus sp. parasitize 50 S. frugiperda’s eggs succesfully parasitized 35 of the 50 S. frugiperda’s eggs or equivalent to 69.40%. As the S. frugiperda’s egg that has been parasitized by the Telenomus sp. parasitoid hatch, the number of females produced from the S. frugiperda host reached 74% and the number of male offspring was only 26%. An analysis of the Telenomus sp. parasitic levels on the S. frugiperda’s egg can be an important factor in biodiversity control and have high potential for controlling egg population of S. frugiperda on the maize plant. Surely this study can help the farmer in decreasing use of pesticides or another dangerous chemicals.

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.

Abstract

BBTV (Banana Bunchy Top Virus) is a viral disease that attacks cultivated banana plants and can cause stunting. The symptoms of BBTV disease attack on banana plants are narrowed, piled up leaves and stunted plants. The disease is caused by an insect vector. Pentalonia nigronervosa is the vector insect that transmits BBTV disease. The purpose of the research was to see the java turmeric plant as an alternative host for population growth and BBTV disease vector. The method in the study used a Randomized Group Design. This treatment consists of two treatments with 10 replications. Based on the results of research conducted on the population of P. nigronervosa experienced fluctuations, but high growth in water media. BBTV disease that attacks banana plants in each treatment has the highest incidence in the control treatment, namely, 73.33% dan the lowest disease incidence the turmeric treatment was 6.67%. The highest intensity of BBTV disease attack in the control treatment was 42.06%, while the lowest in the Javanese turmeric treatment was 1.50%. P. nigronervosa inoculated on Javanese turmeric for 72 days can suppress BBTV disease transmission. However, based on the analysis of each treatment, no significant differences were found. P. nigronervosa has the highest population in the soil medium 95.4 individuals and water medium 86.7 individuals. The population of P. nigronervosa has a good development in turmeric plants.

Abstract

Trichoderma is used as a biological control agent, this fungus has microparasitic and antibiotic properties against soil-borne pathogens. This study aims to investigate the impact of Trichoderma on tomato growth and the progression of Fusarium wilt disease infection. The method used was the Complete Randomized Design (CRD) method. Data from the observation of the intensity of Fusarium wilt disease attack on tomato plants with treatments (P1, P2, P3, P4, P5) showed no significant differences. The treatment of Trichoderma on plant height, number of leaves, number of flowers, number of fruits, and intensity of attack did not have a significant effect in suppressing the development of Fusarium wilt disease infection in tomato plants. Trichoderma application treatment that had the highest effect on tomato plant growth was found in treatment P4 (tomato seedlings soaked for 25 minutes using Trichoderma). The treatment with the lowest intensity of Fusarium wilt attack was found in treatment P5 (Trichoderma incubation in the soil 10 days before planting), showing a better reduction in wilt intensity compared to other treatments.
