The spatial distribution of Bactrocera dorsalis after 15 years of the 2004 Indian Ocean tsunami in Banda Aceh, Indonesia

Abstract

Bactrocera dorsalis is one of fruit fly species that caused to the decreasing of fruits qualities. The 2004 Indian Ocean tsunami impacted more than 60% Banda Aceh city’s areas and changed the Banda Aceh city’s landscape. The purpose of this study is to analyze the special distribution of B. dorsalis after 15 y of the 2004 Indian Ocean tsunami in Banda Aceh tsunami-affected and non-affected areas. The data was collected from December 2018 to January 2019. The B. dorsalis was trapped by using the Modified Steiner Trap method in four villages, which selected randomly in nine sub-districts in the tsunami-affected and non-affected areas of Banda Aceh. The host plants were selected such as mangos, star fruits, guavas, and jackfruits, which commonly recognized in Banda Aceh. Data was analyzed and presented by using the GIS. After 15 years of the 2004 Indian Ocean tsunami the land and fruits plants have recovered. Bactrocera dorsalis were found in tsunami-affected and non-affected areas with total 2510 of B. dorsalis. There is no significant difference of the spatial distribution of B. dorsalis in both areas.
