The effectiveness of combination Mahogany (Swietenia mahogany) seed and Sour Sup (Annona muricata) leaf pesticide to the time of stop feeding and LC50 Mortality on Armyworm (Spodoptera litura F.)
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 11
Abstract
Spodoptera litura Fabr. is one of polyphagous insect that attacks lot of crop species. Integrated Pest Management (IPM) is a effort to suppress insect pest population. Utilization of plant materials as ingredients insecticide is considered necessary because biodegradable, relatively safe for human, animal, non-target as well as agricultural production. This study uses a combination of Sour Sup (Annona muricata) and Mahogany seed (Swietenia mahogany) as a botanical pesticide. The purpose of this study was to determine the effect of single and combined Mahogany seed (MS) and Sour Sup (SS) leaf extracts against Time stop-feeding and mortality. In this study, concentrations applied to armyworm larvae are control, 100 g/l, 150 g/l, 200 g/l, 250 g/l, 300 g/l and a combination both of them (150 SS + 150 MS; 250 SS + 50 MS; 50 SS + 250 MS; 200 SS + 100 MS; and 100 SS + 200 MS g/l). The results showed that the use of extracts of Sour Sup leaf and Mahogany seed as insecticide either alone or in combination against pests S. litura causing stop eating, causing larval mortality, the ability of larvae to pupae, as well as the ability to imago. However, the the most effective concentration is combination of pesticides obtained in MS 200 and SS 100 g/l with mortality as much as 53.33% at the 72nd hour after application.
