Abstract

The fall armyworm Spodoptera frugiperda J. E. Smith is an invasive pest of maize in Indonesia. The fall armyworm is a polyphagous pest originating from North America which was first discovered in West Africa. This pest control is very difficult because farmers are generally focused on the use of pesticides. For this reason, the method of using sex pheromones is an environmentally friendly alternative for controlling fall armyworm S. frugiperda pests. Innovation in the use of sex pheromones to act as attractants, mating disruption and mass trapping for controlling S. frugiperda pests. Keywords: pheromone, fall armyworm, Spodoptera frugiperda, corn Abstrak Ulat grayak tanaman jagung Spodoptera frugiperda J. E. Smith merupakan hama infasif di Indonesia. Hama ulat grayak, merupakan hama polifag yang berasal dari Amerika Utara yang pertama kali ditemukan di Afrika Barat. Pengendalian hama ini sangat sulit karena petani umumnya terfokus pada penggunaan pestisida. Untuk itu metode pemanfaatan feromon sex merupakan alternatif untuk pengendalian hama S. frugiperda yang ramah lingkungan. Inovasi pemanfatan feromon sex berperan sebagai atraktan, mengganggu terjadinya kopulasi antara jantan dan betina dan perangkap masal untuk pengendalian hama S. frugiperda.

Abstract

Land suitability evaluation is very important in the process of matching land types for specific uses. This research aims to create map of the distribution of land suitability classes for mango plants in Kakas District using technology Spatial . This research was carried out using field survey and geoprocessing methods . Data collection techniques include: documentation , observation and analysis laboratory . Determination class suitability land use method from FAO ie matching observation variables that is condition grow plant Mango and its qualities / characteristics land . In this study, 22 units were obtained land map (SPL) covering an area of 3927.07 Ha spread over several village in Kakas District . Class map suitability resulting land _ that is class suitability S1 land (very suitable ) for criteria nutrient retention and available nutrients . Whereas criteria temperature and rooting media included in class suitability S2 land ( enough appropriate ) scattered and for criteria water availability and levels danger erosion generally enter the S3 class ( according to marginal) spread across all SPL. Temporary level danger erosion is criteria give class N ( no appropriate ) for plant mango at 10 ( ten ) SPL with area 1351.93 Ha.
