Abstract

Spodoptera exigua H. is a pest on shallot plants. S. exigua pest control is usually performed using synthetic insecticides. However, its use can cause negative impacts on humans and the agricultural environment. Therefor, it needs the alternative insecticides that are safer and environmentally friendly such as Zingiber officinale var. Rubrum. The purpose of this research was to obtain the effective concentration of red ginger rhizome filtrate to control the pest Spodoptera exigua H. The research was conducted at the experimental farm of the Faculty of Agriculture, Riau University from September to November 2019. Experiments were carried out using a completely randomized design (CRD) with 5 treatments and 4 replications. The red ginger rhizome filtrate concentration treatment used was 0 ml.l-1 water, 20 ml.l-1 water, 40 ml.l-1 water, 60 ml.l-1 water, dan 80 ml.l-1 water. The results showed that the concentration of red ginger rhizome filtrate 60 ml.l-1 water could control pests S. exigua and could cause total mortality of 82,50% with an initial death time of 7 hours and lethal time 50 of 40,25 hours.

甜菜夜蛾(Spodoptera exigua H.)是葱属植物的害虫。通常使用合成杀虫剂来控制小夜蛾害虫。然而，它的使用会对人类和农业环境造成负面影响。因此，需要更安全、更环保的替代杀虫剂，如红姜。本研究的目的是获得红姜根茎滤液防治甜菜夜蛾的有效浓度。研究于2019年9 - 11月在廖内大学农学院实验农场进行。试验采用完全随机设计(CRD)， 5个处理，4个重复。红姜滤液浓度处理为0 ml -1水、20 ml -1水、40 ml -1水、60 ml -1水、80 ml -1水。结果表明，红姜根滤液浓度为60 ml / l-1水处理可有效防治红姜小蠹蛾，总死亡率为82.5%，初死时间为7 h，致死时间为40、25 h。
