Abstract

Spodoptera frugiperda is an invasive pest that invades Indonesia and attacks maize crops. Suppressing the development of pests needs various control methods, including biological control through the application of natural enemies. Therefore, this study was carried out to prepare the inventory and identified the natural enemies, especially parasitoids of S. frugiperda . This study was conducted on farmer's land in Purwobinangun Village, Sei Bingai Sub-District, Langkat District, North Sumatra Province, Indonesia. It was performed using a survey method by taking samples of eggs and larvae of pests S. frugiperda on maize through a purposive sampling (intentional sampling) method. The sampling was carried out on intercropping and monoculture maize crops. The collected eggs and larvae of S. frugiperda were taken to the Agriculture Faculty, Universitas Sumatera Utara plant pest laboratory to be reared until the parasitoids emerged. The result showed that two species of parasitoids were obtained namely Telenomus sp. and Trichogramma sp., with a level of parasitization of egg reached 80% for intercropping and 62.67% for monoculture. The larval parasitoids were obtained from three subfamilies of parasitoids, namely Cheloninae, Microgastrinae, and Campopleginae, with a level of parasitization around 13.2% for monoculture and 9.2% for intercropping.
俭翅虫(LEPIDOPTERA:NOCTUIDAE)副虫卵和大虫的清点与鉴定
Spodoptera frugiperda 是一种入侵性害虫,入侵印度尼西亚并攻击玉米作物。抑制害虫的发展需要各种防治方法,包括通过应用天敌进行生物防治。因此,本研究编制了天敌清单,并确定了天敌,特别是 S. frugiperda 的寄生虫。本研究在印度尼西亚北苏门答腊省 Langkat 县 Sei Bingai 分区 Purwobinangun 村农民的土地上进行。研究采用调查法,通过有目的的抽样(有意抽样)方法对玉米上的害虫 S. frugiperda 的卵和幼虫进行取样。取样在间作和单作玉米作物上进行。采集到的蚜虫卵和幼虫被送往苏门答腊大学农学院植物害虫实验室饲养,直到寄生虫出现。结果显示,获得了两种寄生虫,即 Telenomus sp.和 Trichogramma sp.,间作的卵寄生率达到 80%,单作的卵寄生率达到 62.67%。幼虫寄生虫来自三个寄生虫亚科,分别是螯足亚科(Cheloninae)、微胃亚科(Microgastrinae)和喙足亚科(Campopleginae),单作和间作的寄生率分别为 13.2%和 9.2%。
