“…These application methods include spray and fertilization equipment, irrigation systems, and specific application techniques, such as cadaver application (Wright et al, 2005;Garcia et al, 2008;Raja et al, 2015). New robotic techniques are also optimized for EPN applications (Erdoğan et al, 2021(Erdoğan et al, , 2023. Although EPNs can be applied with all these techniques in theory, the most preferred application method is drip irrigation because EPNs live belowground and need moisture to move through the soil.…”

Entomopathogenic nematodes (EPNs) can be applied using drip irrigation systems. However, the choice of driplines and types of drippers significantly impacts the efficacy of field applications. This study investigated the performance of EPN applications using two common dripper types (katif and cylindrical drippers) under both pot and field conditions. The primary objective of the study was to optimize EPN applications and create a modular system in which driplines and drippers can be selected based on the target pest or plant. In our modular system, driplines were connected to a battery-powered backpack sprayer rather than an irrigation system. The efficacy of EPN applications was assessed on Galleria mellonella L. (Lepidoptera: Pyralidae) larvae at a commercial dose of approximately 50 IJs cm-2. The results revealed that only 60% of the nematodes were discharged from the cylindrical drippers, with 40% becoming trapped in the irrigation system. In contrast, over 90% of the nematodes were successfully discharged from the katif dripper. As a result, the katif dripper exhibited significantly higher larval mortality compared to all other application methods. These findings emphasize the substantial impact of the dripper type on EPN discharge, while also highlighting the applicability of the modular method for EPN applications.

“…In recent years, regulations implemented by the EU in the field of pest control in agriculture have led to restrictions on pesticide usage (Ewence et al, 2015;Robin & Marchand, 2019;Marchand, 2023). This limitation has emphasized the need for alternative methods in pest control, apart from the use of pesticides (Gerhardson, 2002;Baker et al, 2020;Dede et al, 2022;Erdoğan et al, 2023). One of the most significant and commonly employed alternatives is biological control.…”

Entomopathogenic nematodes (EPNs) are endoparasitic organisms commonly used in the control of agricultural pests. There are several factors that determine the efficacy of EPNs on hosts, with one of the most significant being soil moisture. The aim of this study is to determine the effectiveness of some EPNs on hosts at different doses and under different soil moisture conditions. The study utilized 1 Hybrid Strain and 3 EPN isolates, Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae) HBH hybrid strain, Steinernema carpocapsae Weiser, 1955 TUR-S4 isolate, and Steinernema feltiae Weiser, 1955 (Rhabditida: Steinernematidae) TUR-S3 and S-Bilecik isolates. These species were applied to Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae) larvae at 5, 10, and 15 Infective Juveniles (IJs) doses, under 1, 4, 7, 10, and 13% soil moisture conditions. The study was conducted in 2024 at Bursa Uludağ University, Faculty of Agriculture, Department of Plant Protection, Nematology Laboratory. As a result, the highest mortality rates on T. molitor larvae were obtained at 13% soil moisture with 15 IJs, 100% for HBH, 93.33% for TUR-S4, 86.67% for TUR-S3, and 83.33% for S-Bilecik. This study carries important implications for understanding the relationship between EPN efficacy on hosts and soil moisture.
