Abstract

Chrysodeixis chalcites Esper is the main pests in soybean plants cultivation that can cause damage up to 90%. One of controlling was done by using areca nuts (Areca catechu L.) which has a potential as a botanical insecticide. This study aimed to obtain effective concentrations of areca nuts extract to control Chrysodeixis chalcites Esper pests on soybean plants (Glycine max L.). This research was conducted at the Laboratory of Plant Pest and Experimental Farm, Faculty of Agriculture, Riau University, Pekanbaru from August to November 2018. The study was conducted experimentally using a completely randomized design (CRD), which consisted of five treatments and four replications, namely: the concentration areca nuts extract 0 g.l-1 water, 20 g.l-1 water, 40 g.l-1 water, 60 g.l-1 water, and 80 g.l-1 water. The results showed that the concentration of 80 g.l-1 of water was an effective concentration to control Chrysodeixis chalcites pest with an initial death time of 14 hours, lethal time 50 29.25 hours after application, and total mortality of 87.50%.

试验槟榔果萃取的浓度。用于控制大豆植物中的卵形虫(chrysoixis chalcites Esper)的虫害。

黄曲线虫是大豆栽培中的主要害虫，对大豆造成的危害高达90%。其中一种防治方法是使用槟榔果(arereca catechu L.)，槟榔果具有作为植物性杀虫剂的潜力。本研究旨在确定槟榔提取物的有效浓度，以防治大豆上的黄萎病(Chrysodeixis chalicesper)。本研究于2018年8月至11月在北干巴鲁廖内大学农学院植物害虫和实验农场实验室进行。试验采用完全随机设计(CRD)，共5个处理，4个重复，即槟榔提取物浓度分别为0 g.l-1水、20 g.l-1水、40 g.l-1水、60 g.l-1水和80 g.l-1水。结果表明，80 g.l-1的水浓度是防治黄曲蛾的有效浓度，初死时间为14 h，致死时间为50 ~ 29.25 h，总死亡率为87.50%。
