Efektivitas Konsentrasi Ekstrak Daun Bidara (Ziziphus Mauritiana Lamk.) Terhadap Mortalitas Ulat Grayak Jagung (Spodoptera Frugiperda J.E Smith) Di Laboratorium

---

Maize (Zea mays L.) is a carbohydrate producer that is used as an industrial raw material and animal feed. Maize production in Riau decreased by 15% - 75% due to Spodoptera frugiperda J.E. Smith larvae attack. S. frugiperda must be controlled, but still uses synthetic pesticides that cause resistance, recurgence, and secondary pests. An alternative is to use botanical pesticides from bidara leaf extract (Ziziphus mauritiana Lamk.). Bidara is a potential plant containing secondary metabolites. This study aims to obtain an effective concentration on the mortality of fall armyworms. The research was conducted experimentally with a complete randomized design (CRD) consisting of six treatments and four replicates so that 24 units were obtained, each unit consisting of 10 larvae of S. frugiperda instar 3. The treatment used concentrations of 0%, 2%, 4%, 6%, 8%, 10% bidara leaf extract. Observation parameters consisted of initial time of death, lethal time 50 (LT50), lethal concentration 50 and 95 (LC50 and LC95), daily mortality, total mortality, behavioral and morphological changes, temperature and humidity. Daily mortality data were analyzed using Microsoft Excel, displayed in the form of graphs, described descriptively, data on the initial time of death, LT50, total mortality were analyzed by variance analysis using SAS, then further tested with the honestly significant difference (HSD) at the 5% level. The results showed that 10% concentration of bidara leaf extract was not effective to control Spodoptera frugiperda J.E Smith larvae, because it did not cause mortality equal to or more than 80%. It causing mortality of 60% with an initial time of death of 8.75 hours and lethal time 50 at 76.50 hours after application.
