“…The incidence of EPNs inside dead Caribfly suggests that at least Caribfly larvae are hosts to EPNs. Observations in this study were similar to those reported on Ceratitis capitata , Anastrepha ludens , Anastrepha fraterculus and Bactrocera oleae among others . As shown here, larvae of Caribfly are the most susceptible soil‐inhabiting stage to virulent nematodes because Caribfly larvae are very active and highly motile compared with motionless and diapausing pupae which are noted for very low oxygen consumption .…”

“…On the other hand, the longest (or largest) steinernematids were more effective at suppressing emerging adults following inoculation of pupae in soil microcosms. Pupal mortalities due to EPN species in treatments were generally low and similar to those reported on Mexican fruit fly ( A. ludens ), olive fruit fly ( B. olae ) and Mediterranean fruit fly ( C. capitata ) among others in previous studies, suggesting that EPNs are not able to penetrate and infect pupae of fruit flies because of pupal resistance . Reports explained that the closure of all openings (e.g.…”

“…However, overall mortalities declined as densities of IJs increased beyond the optimum. This type of decline is usually observed when intraspecific competition occurs between IJs at high nematode density …”

“…Rohde et al (2012) found mortality rates of C. capitata larvae higher than 90%. Similar results were found by Foelkel, Monteiro and Voss (2016) for Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae); by Heve et al (2017) for Anastrepha suspensa (Loew) (Diptera: Tephritidae); and by Sirjani, Lewis and Kaya (2009) for Bactrocera oleae (Gmelin) (Diptera: Tephritidae). Rohde et al (2012) tested the efficiency of S. carpocapsae ALL nematodes in controlling C. capitata pupae and found mortality rate of 20% when using 200 IJs per insect, equivalent to 100 IJs cm -2 .…”

Mediterranean fruit fly (Ceratitis capitata) is one of the world's major pests infesting fruit crops, causing significant losses. However, this insect has a soil phase and is a potential target for entomopathogenic nematodes. The objective of this work was to test the efficiency of the nematodes Steinernema carpocapsae ALL and Heterorhabditis amazonensis JPM4 in controlling larvae and pupae of Ceratitis capitata. Petri dishes with filter paper or pots with 200 g of soil were used to assess different nematode concentrations; 20 individuals (larvae or pupae) were placed in each container and the nematode suspension was applied at concentrations of 0, 140, 180, 220, 260, and 300 IJs (infective juveniles) cm-2. The nematode horizontal movement was tested using pots with soil and a metal screen at every 10 cm to define different distances (0, 10, 20, and 30 cm from the application site). Ten larvae and ten pupae were transferred to every distance; 10 mL of the nematode suspension (220 IJs cm-2) were applied at the distance zero; 10 mL of the nematode suspension with 220 IJs cm-2 was applied to each pot, using ten larvae and ten pupae for each evaluation time (0, 10, 20, and 30 days after application of nematodes) to study the effectiveness of these nematodes over time. Both nematodes killed C. capitata larvae and pupae, but S. carpocapsae ALL was the most effective. However, this nematode showed no ability for horizontal movement, which was found in H. amazonensis JPM4 nematodes. Both nematodes showed decreasing efficiency over time.

“…Studies have demonstrated that NEPs are effective in controlling pests of different crops (FOELKEL et al, 2016;GIOMETTI et al, 2011;MANACHINI et al, 2013). Feaster and Steinkraus (1996) and Andaló et al (2010) assessed pupae control of Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) and Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) in maize using NEPs; both pests had mortality rates higher than 90%.…”

Chemical insecticides are widely used to control soil pests but not always effective. Entomopathogenic nematodes (NEPs) are found in the soil and depend on host insects to complete their life cycle, and therefore have the potential to control soil pests. Thus, we aimed to investigate the possible joint use of these control methods by assessing the compatibility of two nematodes (Heterorhabditis amazonensis GL and Heterorhabditis amazonensis MC01) with five crop protection products used for maize seed treatment (Maxim®, Cruiser 350 FS®, Fortenza 600 FS®, Avicta 500 FS®, and Amulet®), as well as one neem-based product (NeenMax®). The experimental design was completely randomized with five replicates, six treatments, and one control, in which only distilled water was added to nematode suspension. Each replicate consisted of a test tube containing 1 mL suspension with 2,000 infective juveniles (IJs) and 1 mL of diluted product, following the manufacturer's recommendation. The evaluated parameters were viability, infectivity on Tenebrio molitor larvae and IJs production after exposure to products. Both nematodes were compatible with NeenMax® and Fortenza 600 FS® since they did not differ from the control and were classified as innocuous. Cruiser 350 FS ® was also compatible with the nematodes since the effect value of the product was lower than 30%. Amulet® was classified as slightly noxious, reducing H. amazonensis MC01 and H. amazonensis GL infectivity by 17.5% and 28.5%, and production by 18.2% and 22.3%, respectively. Despite not having reduced viability, Avicta 500 FS® and Maxim® were considered harmful. This is because Avicta 500 FS® and Maxim® reduced productivity by 70.0% and 72.5% and production by 66.1% and 65.4% for H. amazonensis MC01, respectively. For H. amazonensis MC01, both Avicta 500 FS® and Maxim® reduced infectivity by 76.19%, and production by 63.7% and 62.3%, respectively.
