Entomopathogenic nematodes species applied on the larvae of Palpita unionalis
Source publication
In this study the virulence of Steinernema affine 46, S. feltiae 96, S. carpocapsae 1133 and Heterorhabditis bacteriophora 1144 isolates against the last instar larvae of Palpita unionalis (Hübner) were investigated on plates in laboratory and pots in a climate room. Efficacy of entomopathogenic nematodes were determined at 25 oC using two differen...

Plant-parasitic and entomopathogenic nematodes (PPNs and EPNs) are key groups in crop production systems. This study aims at optimizing nematode sampling and extraction methods to benefit integrated pest management (IPM) through (a) management of PPNs and (b) use of EPNs. The impacts of these methods on PPNs and EPNs to achieve cost-effective and e...
Aggregated movement and population structure are known in entomopathogenic nematodes, which are obligate insect parasites. Aggregation behavior in the absence of external stimuli suggests communication among individuals, often in the form of trail-following, which has not been shown by nematodes of any kind. Interactions among individuals are an es...
Spodoptera frugiperda is a highly destructive and polyphagous pest that causes severe damage to various crops, especially maize. The wide use of chemical insecticides to control S. frugiperda results in resistance against commonly used chemicals and resistant mutations will expand in populations accompanied by a spread to vulnerable areas. Conseque...

Türkiye, is the country of origin of olive trees and being among the world’s leading olive producers. Apparently, most of the olive production is concentrated in Türkiye include Izmir, Aydın, Çanakkale, Balıkesir, Muğla and Bursa provinces. Bactrocera oleae (DIPTERA: Tephritidae), being one of the main pests of olive trees, is an important problem in olive cultivation in Türkiye. Four local entomopathogenic nematode species (S. feltiae/12, S. carpocapsae/1133, H. bacteriophora/70, H. bacteriophora/91), which were detected in different regions of Türkiye by our previous studies, were tested by using a single dose and at 5 different temperatures (10, 15, 20, 25 ve 30 °C). Efficacy of four entomopathogenic nematodes infection rates on B. oleae pupae was determined under laboratory conditions. According to the obtained results, the highest infection rate was observed by Heterorhabditis bacteriophora/91 isolate at 25 °C, and the lowest infection rate was observed by Steinernema feltiae/12 isolate at 10 °C.
