Abstract
Plutella xylostella is one of the most destructive insect pests of cruciferous vegetables.
The leaves of soursop plant is one alternative for substituting synthetic insecticides.
This study was conducted to determine the best concentration of soursop leaves extract
that most suppresses the population of Plutella xylostella. The study was conducted
from August to October 2024 at the UPN Veteran Yogyakarta plant protection
laboratory. This study used a completely randomized design (CRD) with 6 treatments
and 5 replications. The treatments include: P0: Negative control (distilled water), P1:
10% concentration extract, P2: 15% concentration extract, P3: 20% concentration
extract, P4: 25% concentration extract, and P5: 30% concentration extract. The data
obtained were tested using the ANOVA test at a level of 5%. if a significant effect was
obtained, it was further tested using the LSD test at a level of 5%. The result of this
research show that soursop leaf extract had an effect to suppress P. xylostella
population and P5 (30% extract concentration) causes the highest mortality and the
highest in inhibiting the growth of larvae into pupae and imago among other treatments
of soursop leaf extract for P. xylostella, but on the time of larval death parameter the
treatment had no significant effect. To suppress Plutella xylostella pest population to
50% of the population, a soursop leaf extract concentration of 37.4% is required and
to suppress the population to 95%, an extract concentration of 79.52% is required.
