Abstract

Currently, the control of poultry pest Alphitobius diaperinus is still a serious problem because the use of synthetic insecticides has been shown to cause health, resistance and environmental disturbances. Therefore, the exploration of environmentally friendly bioinsecticides is still relevant in order to reduce dependence on synthetic insecticides. This laboratory experimental study used a completely randomized design and was carried out in three stages (repellency test, mortality test and antifeedant test). Percentage of repellency (PR) and antifeedant activity were analyzed by ANOVA and continued with Tukey's test (P < 0.05). Mortality was analyzed descriptively and probit regression to predict of LC50 value. The results showed that PR value and insect mortality rates tended to increase in line with the concentration level of mahogany seed and papaya seed extracts. The highest PR value was shown in the C100 treatment in both extracts, 94.13 and 88.70%, respectively. The C100 treatment of mahogany seed and papaya seed extracts also recorded successive deaths of 100 and 96%, with LC50 values of 49.249 and 52.107%. The antifeedant effect was shown by lower feed consumption. The lowest feed shrinkage was found in the C40 treatment, at 63.56 and 52.66% respectively compared to the control group. The results of this study implied that mahogany and papaya seed extracts have the potential to be developed as bioinsecticides, especially in the control of A. diaperinus. © 2022 Friends Science Publishers
