Parasicity level of Telenomus sp. parasitoid against Spodoptera frugiperda J. E. Smith eggs in the laboratory

Abstract

Telenomus sp. as a biological agent, can be used to control a new pest, namely Spodoptera frugiperda which attacks maize in Indonesia. The purpose of this study was to count the number of eggs of S. frugiperda parasitized by Telenomus sp. and to calculate the level of parasitization of the parasitoid Telenomus sp. against S. frugiperda in the laboratory. Research method that used in this research were searching for S. frugiperda caterpillars and preparation of Telenomus sp. The data analysis used in this research was inferential analysis. The results of this study were tested using the normality test, as well as the homogeneity test, and continued with the Kruskal Wallis test. The results showed that parasite level of parasitoid in tube I, tube II, tube III, and tube IV, namely 0%, 23.5%, 18.3%, 11.3%, and the calculation of sex ratio on Telenomus sp. were 2 females and 1 male were found. This study concludes that the number of parasitoids Telenomus sp. affects the level of egg parasitization.©2020 JNSMR UIN Walisongo. All rights reserved.

Comparison of Spodoptera frugiperda parasitoid performance under laboratory conditions

“…The different rates of parasitism are possible due to parasitoid conditions and different numbers of hosts. Putra & Wati (2020) reported that as the number of parasitoids that parasitized S. frugiperda eggs grew, the rate of T. remus parasitism also increased. Additionally, it was noted that when the number of provided hosts increased, the parasitism rate of Diaphania indica larvae by Apanteles taragamae did as well [29].…”

“…As a critical step in preparing potential biological agents, parasitoids' ability must be tested on a laboratory scale. Meanwhile, research on the ability of natural enemies, such as the parasitoid S. frugiperda, on a laboratory scale in Indonesia is still limited to the egg parasitoid T. remus (18,19). In the current study, research was done to compare the performance of several parasitoids in controlling S. frugiperda.…”

Association of a Global Invasive Pest Spodoptera frugiperda (Lepidoptera: Noctuidae) with Local Parasitoids: Prospects for a New Approach in Selecting Biological Control Agents

“…These studies were primarily focused on the presence/absence, diversity, infestation level, and ecology of S. frugiperda [5,[29][30][31][32]. Research on the performance of local parasitoid species in Indonesia in parasitizing S. frugiperda on a lab scale has even been reported [33,34]. Surveys on the infestation level of S. frugiperda, the association between S. frugiperda with local parasitoids, and its associated parasitism rate have also been carried out but are limited to a specific period [2,5,[35][36][37][38][39][40][41][42].…”
