Effective control of Alphitobius diaperinus using natural bioinsecticides

Abstract

Pest insects known as darkling beetles (Alphitobius diaperinus) are common in poultry farms. These pests can develop into a variety of disease vectors, causing damage
to chicken coops, decreased chick performance, and financial losses to farmers. In
Indonesia, synthetic insecticides are still used for pest control, which is detrimental to
non-target creatures and the environment. The purpose of this study is to analyze the
effectiveness of biopesticides from cinnamon bark extract (Cinnamomum aromaticum), nutmeg seeds (Myristica fragrans), lavender flowers (Lavandula angustifolia),
and lime peel (Citrus aurantifolia), as well as synthetic insecticides alpha-cypermethrin against A. diaperinus larvae and imago. Bioinsecticide levels are 2.5%, 5%,
7.5%, and 10%, while alpha-cypermethrin levels are 1%, 4%, 7%, and 10%, respectively, based on LC50 values. The analysis was repeated three times and the treatment
was carried out every two days for a total of 14 days. The data were analyzed with
paired sample t-tests to determine the average difference in each treatment when there
was an average difference and calculated N-Gain score to determine the effectiveness
of biopesticides and synthetic insecticides. The average value of N-Gain essential oil
from cinnamon bark extract was successful in causing A.diaperinus death in the imago
stage (81.14) and the highest larvae (80) of other test solutions. Cinnamon bark extract
and nutmeg seed extract are effective in imago (95.14) and larvae (78.91), respectively, and can be used as a natural biopesticide to replace synthetic insecticides in the
control of A.diaperinus in imago and larvae stages.
