Abstract

Green betel leaves (Piper betle L.) have the potential as bioinsecticide on
Diamondback Moth (Plutella xylostella). This research aimed to determine the
effectiveness of green betel leaves (GBL) extracted with different solvents (ethanol
or n-hexane) on the mortality and survivorship of diamondback moth. The research
was conducted at the Plant Protection Laboratory of UPN “Veteran” Yogyakarta in
April-June 2024. This research used a Completely Randomized Design (CRD)
consisting of 7 treatments: control (without extract), P1 (0.5% GBL extracted with
ethanol), P2 (1% GBL extracted with ethanol), P3 (1.5% GBL extracted with
ethanol), P4 (0.5% GBL extracted with n-hexane), P5 (1% GBL extracted with n�hexane), and P6 (1.5% GBL extracted with n-hexane). Observation parameters
included mortality of larvae, larval death time, feeding activity, percentage and time
of larvae becoming pupae, percentage of larvae becoming imago, time for pupae
becoming imago, and effectiveness of extracts. The data obtained were analyzed
using ANOVA and then tested further using the LSD test at a 5% level. 1.5% GBL
extracted with ethanol gave the highest larval mortality, decreased feeding activity,
and effectiveness extracts and gave the lowest percentage and time of larvae
becoming pupae, percentage of larvae becoming imago, and time for pupae
becoming imago.
