The Diversity and Abundance of Egg Parasitoids in Brown Planthopper, Nilaparvata lugens Stål. (Hemiptera: Delphacidae) at Different Rice Growth Phases in Saketi, Pandeglang, Banten

Abstract

An extensive study about egg parasitoid biodiversity in different plant growth stages is an important need. This study was aimed to determine the diversity and abundance of egg parasitoids Nilaparvata lugens on different rice growth stages in Saketi, Pandeglang, Banten. The parasitoids sample was collected three times with two days interval sampling in three villages, i.e. Sodong (location I), Sindanghayu (location II), and Sukalangu (location III) from February to September 2018. Ten plants (as bait: rice that infected by N. lugens eggs) were put during two days along the transect line (100 meters) with 10 m space in between. The findings revealed that the abundance richness (S), the diversity index (H'), and similarity (J') of egg parasitoids of N. lugens were higher in the location I than those in the locations II and III. The study indicated that the diversity and abundance of egg parasitoids of N. lugens decreased in the generative phase of rice growth.

Ability of commercial Beauveria bassiana to suppress the brown planthopper attack by inducing resistance into different rice variety

“…Intensive and excessive application of insecticides has encouraged the emergence of BPH resistance (Datta and Banik 2021;Iamba and Dono 2021;Utari et al 2023). Various environmentally friendly controls have been recommended to reduce the BPH population, such as ecological engineering (Horgan et al 2016) and the use of natural enemies such as predators (Syahrawati et al 2015;Nasral et al 2020;Syahrawati et al 2021a;Syahrawati et al 2021b;Siregar et al 2023;Utari et al 2023), parasitoids (Minarni et al 2018;Abdilah and Susilo 2020), and insect pathogens, such as Beauveria bassiana (Hendra et al 2022;Kurniawati et al 2021;Mascarin and Jaronski 2016;Trizelia et al 2023).…”

Virulence of Five Isolates of The Entomopathogenic Fungus, Metarhizium anisopliae, Against Brown Planthopper (Nilaparvata lugens)

“…For this reason, it is necessary to find alternative controls that can reduce the negative impact of insecticides. Integrated Pest Control Technology (IPM) is considered an appropriate and potential technology to BPH, such as exploiting natural enemies as like as predators (Siregar et al, 2023;Utari et al, 2023;Syahrawati et al, 2021a;Syahrawati et al, 2021b;Nasral et al, 2020;Syahrawati et al, 2015), parasitoid (Haryati et al, 2015;Minarni et al, 2018;Abdilah & Susilo, 2020), and entomopathogenic fungus (Trizelia et al, 2023;Hendra et al, 2022a;Hendra et al, 2022b), including Metarhizium anisopliae.…”
