“…Our study has shown a significant degree of susceptibility of neonate larvae of C. sordidus to infection by the EPNs tested. Previous authors have shown the susceptibility to EPNs among neonate larvae of other beetles such as Capnodis tenebrionis L. (Coleoptera: Buprestidae) (Garcı´a-delPino and Morton 2005) and Premnotrypes suturicallus (Coleoptera: Curculionidae) (Parsa et al 2006). However, Loya and Hower (2003) showed that EPNs were unable to kill first instar clover root weevils (Sitona hispidulus) at any concentration.…”

We evaluated the efficacy, against neonate larvae of the banana weevil, Cosmopolites sordidus (Germar) (Coleoptera, Curculionidae), of two indigenous entomopathogenic nematode species of the families Steinernematidae and Heterorhabditidae. The nematodes, isolated in the Canary Islands (Spain), were Heterorhabditis bacteriophora (TF19) and an undescribed species (TF135) of the Steinernema feltiae-group. Exposure of C. sordidus neonate larvae to 5 concentrations (2.5, 5, 25, 50 and 100 infective juveniles/cm 2 ) in Petri dishes with sterile sand resulted in 100% mortality, with each of the two nematode species at all concentrations tested. The lowest median lethal time (LT 50 ) for Steinernema sp. was 2.6 d at a dose of 25 infective juveniles/cm 2 and 3.6 d for H. bacteriophora at a dose of 2.5 and 5 infective juveniles/cm 2 . The penetration rate was also evaluated as an indicator of entomopathogenic nematode infectivity. The highest values for penetration rate were recorded at lowest concentrations of infection in Steinernema sp. and in H. bacteriophora, but rates differed regardless of the LT 50 . Our results suggest that these two nematode species may improve the biological control of neonate larvae of C. sordidus in banana crops.

“…EPNs are effective biocontrol agents of a variety of economically important insect pests (Klein, 1990;Shapiro-Ilan et al, 2002) and can provide effective biological control of some important soil insect pests and pests that occur in cryptic habitats (Georgis and Manweiler, 1994;Koppenhöfer, 2000). In fact, the ability of EPNs to find hosts hidden in cryptic environments gives them an advantage over insecticides and other entomopathogens (Parsa et al, 2006). The selection of the best nematode species or strain for one target pest is important, as there are large differences in the virulence of nematode species and strains against different species of pests (Grewal et al, 2005).…”

The virulence of 14 Steinernema feltiae isolates, one S. carpocapsae and three Heterorhabditis bacteriophora isolates was compared in the laboratory against larvae, pupae and adults of the flatheaded root borer, Capnodis tenebrionis. Larval mortality ranged from 50 to 100% and pupae mortality from 0 to 70%. Adults were exposed to different nematode concentrations, 50 and 100 infective juveniles/cm 2 . Steinernema feltiae caused the highest mortality at the two doses tested, reaching 66.7% and 100%, respectively. Significant differences in mortality between C. tenebrionis males and females were observed. The differences in virulence observed at each stage of C. tenebrionis vary within a species and can be higher than differences among species. The results of this study suggest that some of the isolate strains have potential for improved biological control of C. tenebrionis.
