Abstract

Until now, the control of S.litura relies on the intensive application of insecticides with
high doses. The use of natural enemies, particularly parasitoids and insect pathogens,
as biological insecticides has been considered by many to be the most viable pest
management alternative.This Study was to identify the effectivness of
enthomopathogenic nematodes for reducing Spodoptera litura larvae population,
determine the best entomopathogenic nematodes (EPN) concentration that is
effectively reduce the Spodoptera litura larvae. This research will be conducted at the
Plant Protection Laboratory of the Universitas Pembangunan Nasional "Veteran"
Yogyakarta. The research time starts from December 2023 to February 2024. This
research used a completely randomized design (CRD) consisting of 5 treatments. The
treatments are P1 = 50 IJ/mL, P2 = 100IJ/mL, P3 = 150IJ/mL, P4 = 200IJ/mL, P5 =
250IJ/mL, P0 = 0 IJ/mL. Each treatment was repeated 4 times. The data obtained were
analyzed with variance analysis (ANOVA) at the 5% level, then further tested using
the BNJ test at the 5% level. The results of this study obtained that Entomopathogenic
Nematodes (EPN) can increase the mortality of S. litura after third instar. The highest
result on mortality of S. litura shown on P4(200IJ/mL) and P5 (250IJ/mL)f or killing
total 97,5% of 80 larval test in 96 hours.
