“…Interestingly, 50 IJs cm −2 was significant enough to cause more than 80% larval mortality of C. capitata, suggesting that EPN concentrations higher than 100 IJs cm −2 may cause intraspecific competition among IJs of the same EPN species or strain. This nematode concentration is lower than reported in previous studies 22,31,33 . Gazit et al 22 reported that the highest larval mortality (82.5%) of C. capitata was achieved when S. riobrave was applied at a concentration of 100 IJs cm −2 compared to other concentrations.…”

The Mediterranean fruit fly, Ceratitis capitata Wiedemann, is a deleterious pest worldwide affecting fruit production. The entomopathogenic nematodes (EPNs) are a potential biocontrol agent that could be effectively used to control this Mediterranean fruit fly. In this study, five EPN strains reported from different fields in Morocco were evaluated for their efficacy against C. capitata. In laboratory assays, Steinernema feltiae-SF-MOR9, S. feltiae-SF-MOR10 and Heterorhabditis bacteriophora-HB-MOR7 strains showed significantly higher infectivity and penetration rates when compared to the other strains. S. feltiae-SF-MOR9 caused the highest larval mortality rate (80%) at 50 infective juveniles (IJs) cm−2. However, additional results showed that both S. feltiae strains were significantly effective in controlling C. capitata larvae in apricot (Prunus armeniaca) fruits on soil surface with high mortality rate at 50 and 100 IJs cm−2. Different soil textures and moisture levels resulted in a significant variation in EPN strain virulence against C. capitata. Sandy clay loam soil in combination with 50 IJs cm−2 of S. feltiae (SF-MOR9 or SF-MOR10) caused a higher mortality rate of C. capitata larvae. Furthermore, applying these EPN strains at 50–100 IJs cm−2 in combination with 10–15% moisture level showed optimal results against C. capitata larvae. Therefore, those two Moroccan EPN strains could be used as promising eco-friendly biological agents against C. capitata.

“…Stark and Lacey (1999) reported that the highest infection rate was caused by S. carpocapsae (65%), H. bacteriophora (50%), S. feltiae (35%), and H. marelatus (15%) against Rhagoletis indifferens larvae. Karagoz et al (2009) confirmed the effectiveness of five local EPN species against last-instar larvae of C. capitata under controlled conditions. Sirjani et al (2009) stated that S. feltiae was highly virulent against third instar larvae of Bactrocera oleae (G.) compared to S. carpocapsae, S. riobrave, S. glaseri, H. bacteriophora, and H. marelatus.…”

“…The fruit fly pupae might be resistant to EPN penetration (Malan and Manrakhan, 2009). Many tested EPNs were found to (Lindegren and Vail, 1986;Yee and Lacey, 2003;Soliman, 2007 andKaragoz et al 2009). Efficacy of H. baujardi LPP7 was evaluated against the fruit fly pupae by Minas et al (2016) and recorded more than 80% mortality rate after application of 816 IJs/cm 2 .…”

The oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is one of the major insect pests which renders the fruit to become unfit for human consumption. In severe cases, losses may reach up to 100% in some fruit crops. The present study aimed to investigate the pathogenicity of entomopathogenic nematodes (EPNs), Heterorhabditis bacteriophora, H. indica, Steinernema carpocapsae, and S. asiaticum against B. dorsalis maggots and pupae under laboratory conditions. One milliliter of EPNs, having 50, 75, and 100 infective juveniles (IJs) against maggots and 100, 150, and 200 IJs against pupae, were poured into 9 cm Petri dishes with 20 g sterilized soil as supporting media. The highest maggots' mortality (70%) was obtained after 3 days of application of H. bacteriophora and S. carpocapsae and reached up to (96%) after 9 days. S. asiaticum and H. indica caused 91.16 and 85.87% mortality, respectively, after 9 days post treatment at the highest nematode concentration (100 IJs/ml). Whereas, against the fruit fly pupae, H. bacteriophora caused 69.08% mortality after 9 days at the highest concentration (200 IJs/ml). All nematode species showed high effectiveness against both stages of B. dorsalis. Their application can be further evaluated under field conditions to promote a good biological control of fruit flies for healthier fruit production.

“…The difference may be attributed to nematode strain difference, host species difference, and experimental design. Karagoz et al (2009b) tested the efficiency of 5 native Turkish EPN species against last-instar C. capitata larvae under laboratory conditions. The S. feltiae 09-31 Aydın isolate was highly virulent and caused 78% mortality, whereas S. weiseri and S. carpocapsae killed 50% and 56% of the larvae, respectively.…”

Turkey is the world's largest producer of sweet cherries. The European cherry fruit fly, Rhagoletis cerasi L. (Diptera: Tephritidae), is a major pest of sweet cherry crops in Europe and Turkey. The detection of only one larva in the fruit by the processor can result in the rejection of the entire crop of that orchard and/or farm as "wormy" and unmarketable. The main control tactic for R. cerasi is to prevent the females from laying eggs in the fruit. Currently, only a few insecticides are being used, and their application is debatable due to problems with residual ecotoxicity for humans and beneficial organisms. As an alternative to using insecticides for the reduction of adult populations, 4 indigenous entomopathogenic nematode species, Steinernema carpocapsae (Anamur isolate), S. feltiae (Rize isolate), Heterorhabditis bacteriophora (Ekecik isolate), and H. marelatus (Ankara isolate), were bioassayed against last-instar R. cerasi larvae at different temperatures (10, 15, and 25 °C) and nematode concentrations (0, 100, 500, and 1000 IJs/larva). Temperature and nematode concentration had a significant effect on the efficacy of nematode species. S. feltiae was the most virulent species at all temperatures and nematode concentrations. Only S. feltiae showed higher than 40% mortality at low temperatures (10 and 15 °C). At 25 °C, S. feltiae caused 95% mortality, followed by H. marelatus (82%) and H. bacteriophora (76%), at 1000 IJs/larva concentration. Our results indicate that R. cerasi larvae are highly susceptible to entomopathogenic nematode infection. In particular, S. feltiae has high potential for reducing last-instar larval populations, thus decreasing the adult population in the spring.
