Abstract

The research was conducted to inventory and identify as well as acknowledge the correlation between vegetation type with soil arthropods in the Green Barrier area of PT Pusri. PT. Pusri green Barrier area is 28 hectares and dominated by 10 types of vegetation, such as, the Angsana (Pterocarpus indicus Wild), Bambu (Bambusa Sp), Beringin (Ficus benyamina), Buah Roda (Hura crepitans L), Jati (Tectona grandis L), Kelampayan (Neolamarckia cadamba) , Ketapang (Terminalia catappa L), Mahony (Swietenia macrophylla King), Pulai (Alstonia scholaris), and Sengon (Paraserianthes falcataria L). Soil arthropods were collected by using pit fall traps and funnel barlese-tullgren in every type of vegetation, between July-August 2015. Identification of arthropod genera Identification has been done in Entomology Laboratory of the Agriculture Plant Disease Faculty Sriwijaya University, and analysis of soil organic in the Laboratory of Soil Faculty of Agriculture Sriwijaya University. The results were obtained into 3 classes of soil arthropods belonging to the 10 orders, 28 families and 35 genera. The diversity index value of soil arthropods in various types of vegetation is classified moderately (H= 1-3), and no type of soil arthropods were dominant, mean that soil arthropods with different types spread over in the various types of vegetation in the area of Green Barrier PT. Pusri. Light intensity abiotic factors play an important role in the life of the soil arthropod communities in vegetation Sengon (Paraserianthes falcataria L) with a correlation coefficient 1.00Keywords: soil arthropods, community structure, a biotic factors, Green Barrier PT.

Abstract

The research was purposed to inventory and identification types of entomofag and phytophage insects on Passionflower Flower Plants in the area of PT. South Tania Branch East Burnai I. The area of research in PT. Tania Selatan East Iango Branch I is  ± 20 hectares, dominated by two species of Passionflower Flower, there are Passionflower Yellow Flower (Turnera subulata J.E SM.) and Passionflower White Flower (Turnera ulmifolia L.). Entomofag and phytophage insects were collected using d-vaccum, and sweep net in every kind of Passionflower Flowers, started July until August 2017. The identification of entomofag and phytophage insects were done in the University of Sriwijaya Postgraduate Laboratory. The results of the study were 8 orders, 34 families and 48 species on Turnera subulata plants, and 9 orders, 26 families, 36 species on Turnera ulmifolia plants. The value of diversity index from entomofag and phytophage insects in Turnera subulata  were 2.912 plant and the value of diversity index from entomofag and phytophage insects in Turnera subulata plants were 2.603.

Abstract

This study aimed to know the influence of planting the flowering plants in sugarcane plantation on the index value of diversity, domination, and the eveness of phytophage and entomophage insect species in sugarcane plantation. This study was done on two-month and six-month sugarcane of PT.  Perkebunan Nusantara VII Cinta Manis District. The research location is located in Ketiau Village, Lubuk Keliat District, Ogan Ilir Regency, South Sumatra. The study was conducted from July to December 2018. Insects that came to flowering plants were collected by using fitfall traps, nets, and direct capture of insects that came. The results showed that the age of sugarcane affected the diversity of Entomophage and Phytophage insect species that came to the flowering plants. At 2-moth-old sugar cane plantations were found 42 species (388 individuals) and 6-month-old sugarcane plantations were found 41 species (284 individuals). The diversity of Phytophage and Entomophage species that came to flowering plants in  the 2-month-old sugarcane plantations was almost the same as in the 6-month-old sugarcane plantations. Phytopage species diversity index values were 2,826 and 2,548, while Entomophage were 2,564 and 2,867.

Abstract

Aphids is one of the main pests that attack curly red chili plants. Bioinsecticides can be an alternative to synthetic insecticides in controlling aphids. Tobacco leaf extract and tannin can act as insecticides against various types of insect pests. The aim of this study was to determine the effectiveness of formulations containing fermented mixtures of tobacco leaves and tannin as bioinsecticides against aphids on curly red chili plants. The efficacy experiment was conducted in a greenhouse arranged in a completely randomized design (CRD) with 5 formulation concentration treatments, namely 10%, 5%, 2.5%, 1.25%, and 0% (water), with 5 replications. The treatment was carried out by directly spraying the formulation liquid onto the underside of leaves infested with aphids. The results showed that the tobacco and tannin formulation treatments significantly reduced aphid populations, particularly at the 5% and 10% concentration treatments. The efficacy of population suppression reached 92% after 3 days for the 10% concentration and suppressed the population by 93% after 5 days of application for the 5% concentration. After 7 days of application, the efficacy of aphid population suppression was 99% and 100%, respectively, for the 10% and 5% concentrations. The LT50 values for population suppression occurred after 1.18 and 2.67 days for the 10% and 5% concentrations, respectively. The fermented mixture of tobacco and tannin formulations has the potential to be used as a bioinsecticide for controlling aphids.

Abstract

The use of pesticides is one of the control alternatives that is widely used by farmers. However, continuous and inappropriate use of pesticides can have negative impacts on humans and the environment. This research aims to determine the relationship between the level of farmer compliance in using pesticides and pest attacks, disease, natural enemy populations and product safety. The research was conducted in two areas, namely Tanjung Lago and Pemulutan by interviewing farmers and direct observation of rice fields. The variables observed were the percentage and intensity of pest attacks, plant disease. and natural enemy populations. The level of farmer compliance is connected to field data and the correlation efficiency is calculated. The relationship between farmer compliance in the use of pesticides against pests and disease is negatively correlated, and positively correlated with the population of natural enemies.  Using herbal pesticides according to the dosage can reduce the negative impact of pesticides on the environment.
