Abstract

The parasitic level research and description of the parasitoid species which were parasitic towards Aphis gossypii (Glover) (Hemiptera : Aphididae ) origin the agroecosystem of the lowland and highland of South Sumatra has not been reported, although this information is needed as a foundation of biological control of A. gossypii in South Sumatra. The purpose of this study was to determine the parasitic level and provide information about the description of the parasitoid which were parasitic towards A. gossypii origin the agroecosystem of the lowland and highland of South Sumatra. Survey and exploration the parasitoid which were parasitic towards A. gossypii conducted at 11 sites in South Sumatra vegetable center.  The identification of parasitoid species was conducted in the laboratory of Entomology Department of the Faculty of Agriculture University of Sriwijaya. The results showed the parasitic level of Aphidius sp. and Diaeretiella rapae was higher during the dry season in both lowland and highland compared to the parasitic level of Aphelinus sp. However, Aphelinus sp. could only spread in the lowland. The main characteristics of Aphidius sp. (Aphidiidae) has shaped antennae filiform and segmented 13. The front wings have a triangular pterostigma. D. rapae, (Aphidiidae) has shaped antennae filiform and segmented 14. The front wings has a triangular pterostigma. The hind wing has a perfect basal cells. Aphelinus sp. (Aphelinidae) has an shaped goblets antennae and eight segmented and the last segments three of the antennae enlarged or club. Marginal venation long wings, while the venation postmarginal and stigma reduction. In addition there are two species of hyperparasitoid which were found to be parasitic towards parasitoid A. gossypii, were Ooencyrtus sp. and Aphiidencyrtus sp. (Encyrtidae) especially in the lowland.

Abstract

Anggraini et al, 2018. Host-Range Analysis of Downy Mildew (Pseudoperonospora cubensis) and Anthracnose (Colletotrichum Sp.) on some Cucurbitaceae Plants. JLSO 7(2):213-224. Inhibiting factors of cucumber cultivation is Downy mildew disease that is caused by Pseudoperonospora cubensis and Anthracnose by Colletotrichum sp. The objective of this research was to observe pathogenicity of activity caused by Pseudoperonospora cubensis and Colletotrichum sp. isolated from cucumber towards Cucurbitaceae plants. The research was conducted at greenhouse and Phytopathology Laboratory, Department of Plant Pests and Diseases Faculty of Agriculture, University of Sriwijaya in September to December 2016. This study used Randomized Block Design (RBD), with four types of plants, 2 treatments and 4 replications. The results showed that the incubation period of the plant inoculation Downy mildew by Pseudoperonospora cubensis range between 4.5-5.0 days. Result of broadest spot area was on melon leaf 2.05 cm2 with the chlorophyll content of 0.4928 mg/g and the lowest result was on cucumber leaf 0.90 cm with the chlorophyll content of 0.7628 mg/g. While the results showed that the incubation period of the applied plant pathogen Colletotrichum sp. ranging from 3.0-4.5 days. Result of broadest spot area was on melon leaf 4.00 cm2 with the chlorophyll content of 0.3932 mg/g and the lowest result was on cucumber leaf 2.42 cm2 with the chlorophyll content of 0.7588 mg/g.

Abstract

Hanif et al, 2019. Population of Pest Insects and Predatory Arthropods Inhabiting Freshwater Swamp Rice of South Sumatra Treated with Bioinsectide of Beauveria bassiana and a Synthetic Insecticide. JLSO (8)1:31-38.Entomopathogenic fungi, Beauveria bassiana, could  kill various species of insect pests, but  their impact on predatory arthropods needs to be studied. The aim of this study was to compare population of pest insects and predatory arthropods inhabiting rice sprayed with bioinsecticide of B. bassiana and conventional rice field using a synthetic insecticides. Bioinsecticide was made from conidia of B. bassiana and sprayed on rice canopy. The plot of conventional farmers was sprayed with synthetic insecticides made from Abamektrin. The results showed that the application of bioinsecticide of B. bassiana was not proven to reduce the pest insect population. The abundance of natural enemies of pest insects, such as  spiders and predatory insects was also more abundant in plots sprayed with  bioinsecticide than conventional plots that used synthetic insecticide. The synthetic insecticides have been shown to reduce the abundance of predatory insects and spiders. Bioinsecticides containing carrier of  liquid compost were proven to increase the growth and development of rice, which was an increase in the number of rice tillers per clump in plots applied by bioinsecticide. Thus, B. bassiana of bioinsecticide with liquid compost carrier material was safer and could maintain the abundance of predatory arthropods and increased rice growth.
