The research was conducted to analyze the diversity, dispersal and domination of the egg parasitoid species of the yellow rice stem borer Scirpophaga incertulas Walker on several land typologies in Jambi Province. The study was conducted by survey method, from December 2010 until June 2011. Samples of egg parasitoids of S. incertulas were collected by baiting parasitoids with eggs of S. incertulas. The results of the research showed that there were three spesies of the egg parasitoids of S. incertulas found in Jambi Province, the most dominant was Telenomus rowani Gahan, followed by Trichogramma japonicum Ashmead and Tetrastichus schoenobii Ferriere. T. rowani and T. japonicum were found in all wetland ecosystems in Jambi Province (tidal swamp, swampy area, rainfed lowland, lowland technical irrigation, and upland technical irrigation), while T. schoenobii was found only in tidal swamp, swampy area, and lowland technical irrigation. The highest species diversity of egg parasitoid of S. incertulas was found on tidal swamp (Shannon index 1.047), followed by swampy area, lowland technical irrigation, rainfed and upland technical irrigation area. The average of proportion of egg masses parasitized by T. rowani, T. japonicum and T. Schoenobii were 22.58, 6.18 and 2.68% respectively. The average of individual eggs parasitized by T. rowani, T. schoenobii, and T. japnicum were 8.41, 1.67 and 1.47% respectively.

Information on the diversity of dragonfly in the University area is still not much. Reduced areas that support the growth and development of dragonfly species are thought to have an impact on the decline of the population and the diversity of these species. The purpose of this study identified and analyzed the diversity of dragonfly species. Dragonfly are collected through direct capture and using sticky traps, then visual observations are made for identification. Environmental conditions in the area of Sriwijaya University Campus is still good, with the visibility of environmental parameters in the form of DO, BOD and COD still meet environmental quality standards so that dragonflies are still able to lay eggs to keep their generation. Sriwijaya University campus found 19 species of Odonata belonging to 5 families and 2 sub-ordo, with the value of species diversity index of 2.05 and moderate

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 603-610. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Bees are pollinating insects acting as pollinators on various kinds of plants, both cultivated plants, ornamental plants and wild plants. Bee visits to various plants can provide benefits for both parties, where bees get benefit from getting pollen and nectar as a source of food, while the infested plants get benefit from pollination assisted by bees. The purpose of research was to investigate bee species of Apidae family on various species of flowering plants in Pagaralam City. Surveys of Apidae bees have been carried out in three sub-districts of Pagar Alam City, South Sumatera, namely North Dempo District, South Pagaralam District and North Pagaralam District on 14 plant species spread over eight different villages. Observations were conducted from May to June 2021. Observations were carried out using scan sampling method (direct observation) and using insect net. At observation time, bees were taken using insect nets and put in a bottle vial for population count and identification purposes. Environmental parameters included temperature and humidity measured every time of observations, the morning air temperature (08.00-10.00) ranged from 21oC-27oC with air humidity of 73%-91%. It was found 4 species of bees belong to the Apidae family namely A. dorsata, A. cerana, T. laeviceps, dan X. violace. Each of bee played a role as pollinators in various flowering plants observed.

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.
