Abstract

Ant diversity in the plantation ecosystem has an important role in maintaining the balance of the ecosystem and the continuity of crop production. It aims to find out ant diversity and the role of ants present in oil palm, rubber, and cocoa plantation ecosystems in Dharmasraya District. The research location is Kecamatan Pulau Punjung, Sitiung, and Koto Besar. The method used in this research is Systematic Random Sampling (Random Design Selected). Sampling using the Qudran Protocol method is Soil And Leaf Litter Sieving, Pitfall trap, Bait Trap, and Hand Collecting. Identification is done at the Laboratory of Animal Taxonomy, Biology Department, Faculty of Mathematics and Natural Sciences, Andalas University. The diversity and evenness of ants in some types of plantations in Dharmasraya Regency were moderate (H '<1) and (E <0.63). There were 16 species of ants; the most abundant species were Aneplolephis graciliphes and Odontoponera denticulate.

Abstract

This research observed about the structure of Dermaptera insects community on oil palm trees. This research is aimed to study about the structure of the community and the abundance of each species of Dermaptera on oil palm trees. The research is conducted in three places, they are Nagari Gunung Selasih, Sungai Dareh and IV Koto. The research is conducted using hand collecting method once a month. It is operated two times in October and November 2017. Result shows that there are four species of Dermaptera found in the three places, they are Chelisoches morio, Doru aculeatum, Euborellia arcanum and Vostox apicedentatus. The most common species found is C. morio. It is also found that the structure of Dermaptera is not complex because it’s unevenness and has a low biodiversity value.

Abstract

Nurseries are one of the essential agronomic activities in oil palm cultivation. Oil palm seedlings are cultivated on a large scale, different from nurseries for other plantation commodities. The nursery expanse comprises various biotic components, one of which is Arthropods. This study aims to determine the Artropod community and its function in oil palm nurseries. The research was carried out at two nurseries, Nagari Gunung Medan and Nagari Kurnia Selatan, Dharmasraya Regency, West Sumatra Province. Sampling using the pitfall trap, yellow pan trap, insect nets, and direct collection methods. The results showed that the Arthropods that make up the oil palm nursery ecosystem were insects and spiders. Arthropods in oil palm nurseries act as phytophages, predators, parasitoids, and detrivores. Phytophage insects found in oil palm nurseries were 700 individuals consisting of 4 orders, nine families, and 14 genera/species. Predatory insects, parasitoids, and detritivores were found in as many as 466 individuals consisting of 5 orders, 14 families, and 16 genera/species. There are two species of spiders in oil palm nurseries: Pardosa sp and Oxyopes javanus. Valanga sp was the species with the highest number of individuals in oil palm nurseries.

Abstract

Forest conversion to oil palm plantations forms a unique agroecosystem. Forests known as a source of biodiversity are bordered by oil palm plantations with low diversity. The location of the oil palm plantation, which is directly adjacent to the forest, is thought to affect the diversity of spiders found in the agroecosystem. This study aimed to determine the effect of the distance between oil palm plantations and forests on spider diversity. The research was conducted at oil palm production centers in West Sumatra Province, Indonesia, namely Dharmasraya Regency, Pulau Punjung District, Nagari Gunung Selasih, and Sungai Kambut. In oil palm plantations, 10 sample plots (1 m x 1m) were determined along the transect line, 1 km from the forest's edge. Spiders were collected using the pitfall trap, knockdown, and hand collection methods. The spider diversity was analyzed by applying the diversity and evenness index by Shannon-Wiener. The results showed that the distance of the oil palm plantation from the forest affected the diversity of spiders. The closer the oil palm plantation is to the forest, the higher the diversity of spiders. The results of this study can be one of the considerations for oil palm business actors to maintain forests as conservation areas for organisms that provide various ecosystem services, including spiders as predators of oil palm pests.

Abstract

Weed is one of the major problems in immature oil palm plantations. Weed control is carried out to optimize the growth of oil palm plants, and the method commonly used in the field is chemical control with herbicides. The active ingredient of the herbicide used in the field is triclopyr, however herbicide application is thought to affect the diversity of insects, especially those found in lower vegetation, at the same time it is necessary to observe the effect of herbicide application on insect diversity. This study aims to obtain an effective dose of herbicide to control weeds in immature oil palm plants and to determine the effect of herbicide application on insect diversity. This study used a Randomized Block Design (RBD) which consisted of 6 treatments and 4 replications. Triclopyr herbicide treatment doses were 864 g.ha-1, 768 g/ha, 672 g.ha-1, 576 g.ha-1, mechanical weeding and control. Insect sampling method uses insect nets and pitfall traps. The data obtained were analyzed using variance or F test at 5% level and further test was carried out by DMRT at 5% level. The results showed that the best dose of herbicide triclopir was 768 g/ha because it was effective in controlling the weeds of Borreria latifolia, Calopogonium mucunoides and Asystasia gangetica. Triclopyr herbicide application affects the diversity of insects and the even distribution of insects.
