Abstract

This study aims to determine the types of predators and parasitoids of S. frugiperda in North Minahasa Regency. This study used descriptive explorative method with 2 stages, namely the sampling stage in the field, 27 samples of S. frugiperda egg groups were taken from corn plantations that were 1-2 weeks old and then maintained in the laboratory until they hatched and samples of predators and parasitoids of S. frugiperda larvae were taken from corn plantations that were 4 weeks old and had not been sprayed with pesticides. The next stage is observation in the laboratory, samples of predators and parasitoids of S. frugiperda are observed by looking at their morphological characteristics then the results of this study are presented in the form of descriptive tables and figures. The results of this study found 5 types of predators on S. frugiperda, namely Tetraqnatha sp. (Aranae: Tetragnathidae), Paederus sp. (Coleoptera: Staphilinidae), Cheilomenes sp. (Coleoptera: Coccinellidae), Neurothemis sp. (Odonata: Libellulidae), and Family Forficulidae Order Dermaptera, for parasitoid species found 2 types of egg parasitoids and 1 type of larval parasitoid, the type of egg parasitoid S. frugiperda is Trichogramma sp. (Hymenoptera: Trichogrammatidae), Telenomus sp. (Hymenoptera: Scelionidae) and the type of larval parasitoid Apanteles sp. (Hymenoptera: Braconidae).

北米纳哈萨县玉米植株上的 Spodoptera frugiperda J. E. Smith 的天敌和寄生虫种类
本研究的目的是确定北米纳哈萨县蚜虫的天敌和寄生虫类型。本研究采用描述性探索方法,分为两个阶段,即在田间取样阶段,从玉米种植园中提取 27 个 1-2 周龄的笛琶蝽卵组样本,然后在实验室中保存至孵化;从 4 周龄、未喷洒杀虫剂的玉米种植园中提取笛琶蝽幼虫的天敌和寄生虫样本。下一阶段是在实验室进行观察,通过观察天敌和寄生虫的形态特征来观察 S. frugiperda 的样本,然后将研究结果以描述性表格和数字的形式呈现出来。(Coleoptera: Coccinellidae), Neurothemis sp. (Odonata: Libellulidae), and Family Forficulidae Order Dermaptera, for parasitoid species found 2 types of egg parasitoids and 1 type of larval parasitoid, the type of egg parasito S. frugiperda is Trichogramma.frugiperda的卵寄生虫类型为Trichogramma sp.(膜翅目:Trichogrammatidae)、Telenomus sp.(膜翅目:Scelionidae),幼虫寄生虫类型为Apanteles sp.(膜翅目:Braconidae):捕食者 寄生虫 Spodoptera frugiperda CornAbstrakPenelitian ini bertujuan untuk mengetahui jenis-jenis predator dan parasitoid S. frugiperda di Kabupetan Minahasa Utara.该项目采用了 2 个阶段的探索方法,包括在腹板上采样 2 个阶段、27 个 S. 弗氏啮齿目动物采样阶段。蛙类幼虫的捕食者和寄生幼虫的采样在实验室中进行。目前,在实验室中,有捕食者和寄生虫样本,以了解其形态学特征。目前有 5 种食肉动物与 S. frugiperda 相关,包括 Tetraqnatha sp. (Aranae : Tetragnathidae), Paederus sp. (Coleoptera : Staphilinidae), Cheilomenes sp.(Coleoptera : Coccinellidae), Neurothemis sp. (Odonata : Libellulidae), dan Famili Forficulidae Ordo Dermaptera, untuk jenis parasitoid ditemukan 2 jenis parasitoid telur ditemukan 1 jenis parasitoid larva, jenis parasitoid telur S. frugiperda yaitu Trichomenes sp.(膜翅目:Trichogrammatidae)、Telenomus sp.(膜翅目:Scelionidae)和寄生幼虫 Apanteles sp.(膜翅目:Braconidae):捕食者, 寄生虫, Spodoptera frugiperda, Jagung
