Abstract：
<b>Background and Objective:</b> <i>Alphitobius diaperinus</i> (Coleoptera: Tenebrionidae) is the major pest in chicken farms. The control of pests using synthetic insecticides is not recommended. Besides its expensive, synthetic insecticides are proved harmful to poultry health, farmworkers and polluting the environment. To explore the sources of bioinsecticides that are cheap and eco-friendly, this study was conducted to evaluate the insecticidal effect of weeds extracts (<i>Chromolaena odorata</i>, <i>Ageratum conyzoides</i> and <i>Tithonia diversifolia</i>) against post-embryonic survival of <i>A. diaperinus</i>. <b>Materials and Methods:</b> The experimental study using a completely randomized design of 2 factors, i.e., 3 types of weeds extract and 6 levels of concentration. The insecticidal effect was observed based on the post-embryonic survival. The post-embryonic survival of larvae was evaluated for 4 weeks by measuring the number of Larvae Released (LR) from the eggs, as well as the number of Adults Emergence (AE). Data were analyzed using Variance Analysis (ANOVA) and continued with the least significant different tests (α<u><</u>0.5). <b>Results:</b> The statistical analysis showed that the differences in extract concentration contributed significant influence (α<u><</u>0.05) on the total number of larvae released and adult emergence. The lowest LR and AE occurred at the 40% concentration level, i.e., on the extract of <i>T. diversifolia</i>, while the highest LR and AE were found in the treatment of <i>C. odorata</i> extract. <b>Conclusion:</b> In this study, all types of extracts have an insecticidal effect on the post-embryonic survival of <i>A. diaperinus</i> but the strongest effect was found in the extract of <i>T. diversifolia</i> in 40% concentration. At last, these findings inform people that the weeds extract, especially <i>T. diversifolia</i> is possible to be developed as bioinsecticides for <i>A. diaperinus</i>.
摘要：
<b>背景和目的:</b>i>Alphitobiusdiaperinus</i>(鞘翅目:Tenebrionidae)是养鸡场的主要害虫。不建议使用合成杀虫剂控制害虫。除了昂贵的，合成杀虫剂被证明对家禽健康有害，农场工人和污染环境。为了探索廉价和环保的生物杀虫剂的来源，本研究旨在评估杂草提取物的杀虫效果(<i>色藻</i>,<i>Ageratumconyzoides</i>和<i>Tithoniadiversifolia</i>)对抗<i>A.的胚胎后存活diaperinus</i>.<b>材料与方法:</b>采用2个因素的完全随机设计的实验研究,即，3种杂草提取物和6个浓度水平。基于胚胎后存活观察到杀虫效果。通过测量从卵中释放的幼虫（LR）的数量来评估幼虫的胚胎后存活4周，以及成人出现人数（AE）。使用方差分析（ANOVA）分析数据，并继续进行最不显著的不同检验（α<u><</u>0.5）。<b>结果:</b>统计分析表明,提取物浓度的差异(α<u><</u>0.05)对释放的幼虫总数和成虫出苗的影响显著。最低的LR和AE发生在40%的浓度水平，即，关于<i>T的摘录多样化植物</i>,而在<i>C的治疗中发现了最高的LR和AE。odorata</i>提取物.<b>结论:</b>在本研究中,所有类型的提取物都对<i>A.的胚胎后存活有杀虫作用diaperinus</i>但在<i>T的提取物中发现了最强的效果。浓度为40%的多种植物。最后,这些发现告诉人们，杂草提取物，尤其是<i>T。多样化可作为生物杀虫剂用于<i>A.diaperinus</i>.
