“…Vasconcelos et al (2004) observed oviposition periods of 10.5 and 13.5 days at the highest concentrations of de S. glaseri SANTA ROSA and H. bacteriophora CCA, respectively, but in no case was there a significant difference in this parameter between the treated groups and the control group. However, like in the present study, Freitas-Ribeiro et al (2005), Silva (2007) and Reis-Menini et al (2008) all observed significant decreases in the values obtained for this parameter. These results along with others reported in the literature demonstrate that different entomopathogenic nematode species do reduce the survival time of engorged R.…”

“…However, the NI efficiency index did not differ significantly between any of the treated groups and the control (p>0.05; Table 3). Freitas-Ribeiro et al (2005) reported that all concentrations of S. carpocapsae (SANTA ROSA and ALL strain) caused significant decreases in the REI of the engorged female ticks, while Silva (2007) found a reduction in the REI and NI only starting at a concentration of 150 EPNs/female.…”

“…The increase of resistant tick populations has prompted efforts to find new strategies for more efficient control, at lower cost and with less serious environmental impacts. Laboratory studies have demonstrated that entomopathogenic nematodes (EPNs) are efficient in controlling cattle ticks by interfering in the biological parameters of the non-parasite phase of engorged females (Vasconcelos et al 2004;Freitas-Ribeiro et al 2005;Silva 2007;Reis-Menini et al 2008).…”

The aim of this study was to evaluate the influence of different doses of Heterorhabditis amazonensis RSC-5 on the biological parameters of engorged females of Rhipicephalus (Boophilus) microplus. The female ticks, individually identified, were divided into six groups of 20 each and exposed to the following nematode concentrations: 0, 75, 150, 300, 600, and 1,200/female. The following parameters were observed: initial weight, final weight, alteration weight, egg mass weight, pre-oviposition period, oviposition period, survival period, incubation period, hatching percentage, reproductive efficiency index (REI), nutritional efficiency index (NI), and percentage of control. There were no significant differences observed for the initial weight, pre-oviposition period, incubation period, and NI (p > 0.05) between the various treated groups and the control group. However, there were significant differences (p < 0.01) for the oviposition and survival periods between all the treated groups and the control group. For the final weight, alteration weight, egg mass weight, and REI, only the treatment with 1,200 nematode/female did not differ significantly from the respective figures for the control group (p > 0.05). The highest control rate was 67.8%, obtained in the treatment with a concentration of 300 entomopathogenic nematodes/female. The results demonstrate that this nematode has a deleterious effect on the majority of the biological parameters analyzed.

BACKGROUND:The control of ticks is challenged by the resistance of tick populations to chemical acaricides. In this study, we evaluated, under laboratory conditions, the efficacy of Heterorhabditis bacteriophora against Rhipicephalus (Boophilus) microplus engorged females with varying body weights (150, 200, 250, 300 or 350 mg per female) or from eight different geographical populations. We also determined the efficacy of H. bacteriophora for tick control under field conditions. RESULTS: R. microplus engorged females with varying body weights exposed to 150 juveniles of H. bacteriophora resulted in a high control efficacy (97.5% to 98.4%). Tests with females from different geographical populations comprised eight tick strains treated with H.bacteriophoraandtheirrespectivecontrolgroups.Thebiologicalparametersoffemalesexposedtonematodetreatmentsdidnotdiffer significantly and resulted in 89% to 99% of control efficacy. Trials conducted under field conditions were performed in field plots with Megathyrsusmaximusgrass.TreatmentgroupsreceivedeightcadaversofTenebriomolitorfully colonizedwithH.bacteriophoraat1 week prior to the release of female ticks, whereas control groups were untreated. On the first day of the experiment, six engorged females were distributed in each plot. On day 42 and day 63, the apical portion of the grasses with R. microplus larvae were collected and quantified. The population of R. microplus larvae was reduced up to 73.1% in plots treated with H. bacteriophora at day 63 after treatment. CONCLUSION: R. microplus engorged females with varying body weights or from different geographical populations were highly susceptible to H. bacteriophora. The field test demonstrated the efficacy of H. bacteriophora in reducing R. microplus larvae in infested pastures.
