Abstract

            The purpose of this research was to investigate effects of superparasitism rate on development of Tetrastichus brontispae progeny. In this research, each host (Brontispa longissima pupa) was exposed for different frequencies, i.e., 1, 3, 5, 7 and 9 times for female parasitoid.  The result showed that the rate of superparasitism affected the number of progeny emergence, the developmental time of immature progeny, and sex ratio of progeny. The number of progeny emergence was increased as the increase of  superparasitism rate. The number of progeny emergence from single oviposition host was 15, while from host exposed on female parasitoid for 3, 5, 7, and 9 times were 12, 5, 2 and 0, respectively. The developmental time of immature progeny was lengthened as the increase of superparasitism rate. Sex ratio of progeny was biased to female progeny as the increase of rate of superparasitism. The result of this research indicated that superparasitism gave negative effect on development of T. brontispae progeny.

Abstract

Trichoderma is a free-living fungus, commonly can be found in soil and root ecosystem.  Extensively, it is capable of producing antibiotics, parasite to other fungus, and microorganism that cause diseases on plants.  The objectives of the experiment were to study effects of Trichoderma on germination and growth of cacao, tomato, and soybean. The result showed that provision of Trichoderma (T. harzianum and T. virens) conidia suspension using seed submersion technique did not affect seed germination of cacao, tomato, and soybean, but significantly affected cacao root extension. Provision of Trichoderma through seed submersion on sand box germination gave a positive response to tomato plant, tolerance to cacao plant, and a negative response to soybean plant.  The causing factors of difference responses varied including concentration, application techniques, and kinds of seed.

Abstract

The research of predatory arthropod species diversity in agro-ecosystem is very important because it affects the function of natural enemies in suppressing pest population. Management of paddy through cultivation method can be part of the conservation of predatory arthropods. This study was conducted to analyze and compare the diversity of predatory arthropod with method cultivation conventional and integrated crop management (ICM) and diversity predatory arthropod based on phase growth paddy from cultivation conventional and ICM. The experiment was conducted in lowland rice agro-ecosystem at two plots with conventional cultivation method and ICM. Sampling of predatory Arthropods was done on the phase growth vegetative and generative paddy using net trap, yellow pan trap, and direct observation in the plants. The results showed that the predatory arthropods found were from Insecta and Arachnida class. The species diversity of predatory arthropod at phase growth of generative was higher than vegetative phase both at the conventional and ICM cultivation. Diversity predatory arthropod on the ICM method was higher compared to conventional. Paddy cultivation method with ICM through the rational use of insecticides can be part of conservation for predatory arthropod species.

Abstract

Shade is one of the obstacles in the cultivation of soybean crops in intercropping systems. This study was aimed at determining the change in the characters of agronomic and morpho-physiological leaves of soybean plants due to shade. The experiment was conducted at the Experimental Farm of Agriculture Faculty, Teuku Umar University Meulaboh in West Aceh, from August to November 2013. The experiment was arranged in a split plot design with three replications, where subplot (varieties: Anjasmoro, Kipas Merah Bireun, Grobogan, Burangrang, Sinabung, Kaba) was nested in the main plot (shade: without shade, 25% and 50% shade). The results showed that the shade and varieties exerted high significant effects on changes in agronomic characters and morpho-physiological leaf variables, except 100-seed weight and ratio of chlorophyll a/b which were not affected by shade and the amount of chlorophyll b and the ratio of chlorophyll a/b not affected by varieties. Interactions between shade and varieties were highly significant on changes in agronomic characters, except variables 100-seed weight.
