ABSTRACT
Shallots (Allium ascalonicum Linn.) are a horticultural commodity in
Indonesia that contain nutrients such as carbohydrates, proteins, fatty acids, and
minerals that play an important role in human health. Attacks by wild betel leaf
caterpillars (Spodoptera exigua Hubner.) can cause crop losses of up to 91%.
Long-term use of synthetic insecticides can trigger pest resistance, resurgence,
and environmental damage. Forest betel is a plant that has the potential to be used
as a botanical insecticide to control S. exigua larvae. This study aims to determine
the concentration of organic extract of forest betel leaves (Piper aduncum L.) on
the mortality of shallot caterpillars (Spodoptera exigua Hubner) in the laboratory.
This study was conducted experimentally using a completely randomized design
(CRD) consisting of six treatments with concentrations of 0%, 0.2%, 0.4%, 0.6%,
0.8%, and 1% organic wild betel leaf extract. Observation parameters include the
onset time of death, lethal time 50 (LT50), lethal concentration 50 and 95 (LC50
and LC95), daily mortality, total mortality, behavioral and morphological changes,
and temperature and humidity. The results showed that organic forest betel leaf
extract with a concentration of 0.8% was effective in controlling shallot leaf
caterpillars (Spodoptera exigua Hubner.) by causing total mortality of around 80%
with an onset time of death of 5.25 hours and a lethal time 50 at 25 hours after
application.
Keywords: Botanical Pesticide, Ethanol, Spodoptera exigua Hubn., Piper
