is an insect pest known for its destructive impact on rice crops. Chemical pesticides continue to be employed for the prevention of . The aforementioned phenomenon exerts adverse effects, notably in the form of human intoxication. Hence, one alternate approach to address the issue involves utilizing a preparation derived from the leaves of the jackfruit tree. The leaves of the jackfruit tree are known to possess many bioactive compounds such as flavonoids, saponins, and tannins, which have insecticidal properties. Hence, the objectives of this study are to investigate the impact of jackfruit leaf extract on the mortality rate of rice insects and to evaluate the quality of rice. The study was carried out in the Biology Laboratory of the Faculty of Education and Teacher Training at the Tadulako University. The study employed a research strategy known as a completely randomized design (CRD), which included five treatments. Each treatment was repeated in four biological and ten technical replicates. The treatments were as follows: treatment A served as the control and involved the use of , treatment B involved the application of a 10% jackfruit leaf extract, treatment C involved the application of a 20% jackfruit leaf extract, treatment D involved the application of a 30% jackfruit leaf extract, and treatment E involved the application of a 40% jackfruit leaf extract. Every treatment was administered through spraying to all ten insects and that was repeated four times. The data collected were subjected to analysis using analysis of variance (ANOVA) and supported by the SPSS-25 software. The findings of the study indicated that the application of jackfruit leaf extract () at specific time intervals (20th, 40th, and 60th minutes) resulted in a noteworthy impact on the death rate of rice beetles. Furthermore, the extracts successfully preserved the olfactory attributes of the rice, ensuring its quality. Nevertheless, their ability to uphold the standard of the rice in relation to its color and flavor was inadequate. The efficacy of the jackfruit leaf extract in eradicating rice bugs was found to be highest when applied at a concentration of 40%.
是一种以对水稻作物具有破坏性影响而闻名的害虫。化学农药仍被用于预防……上述现象会产生不利影响，尤其是以人体中毒的形式。因此，解决该问题的一种替代方法是利用从菠萝蜜树叶中提取的制剂。已知菠萝蜜树叶含有许多生物活性化合物，如黄酮类化合物、皂苷和单宁，这些具有杀虫特性。因此，本研究的目的是调查菠萝蜜叶提取物对水稻害虫死亡率的影响，并评估水稻的品质。该研究在塔杜拉科大学教育与教师培训学院的生物实验室进行。该研究采用了一种称为完全随机设计（CRD）的研究策略，包括五种处理。每种处理在四个生物学重复和十个技术重复中进行。处理如下：处理A作为对照，使用……，处理B使用10%的菠萝蜜叶提取物，处理C使用20%的菠萝蜜叶提取物，处理D使用30%的菠萝蜜叶提取物，处理E使用40%的菠萝蜜叶提取物。每种处理通过喷洒施用于所有十只昆虫，重复四次。收集的数据使用方差分析（ANOVA）进行分析，并由SPSS - 25软件支持。研究结果表明，在特定时间间隔（第20、40和60分钟）施用菠萝蜜叶提取物对水稻甲虫的死亡率有显著影响。此外，提取物成功保留了水稻的嗅觉属性，确保了其品质。然而，它们在维持水稻颜色和风味标准方面的能力不足。发现当以40%的浓度施用时，菠萝蜜叶提取物消灭水稻害虫的效果最高。
