This study evaluated the influence of alternate insects hosts Mahanarva spectabilis and Galleria mellonella on the efficacy the entomopathogenic nematode, Heterorhabditis baujardi isolate LPP7, for Rhipicephalus microplus control. In the first experiment, engorged R. microplus females were exposed to entomopathogenic nematode H. baujardi LPP7 with or without the presence of M. spectabilis nymphs or G. mellonella larvae. There were also groups containing only M. spectabilis or G. mellonella exposed to H. baujardi and a control group for each arthropod. In the second experiment, engorged females were exposed to different concentrations of H. baujardi which were reared from M. spectabilis and G. mellonella. Mortality rates of engorged R. microplus females, held together with EPN-infected M. spectabilis or G. mellonella inside, was 100% after five days, while the group containing only ticks reached 86%. EPNs caused reduction (p < 0.05) in the amount of eggs produced by engorged females. In the second experiment, the use of nematodes reared in M. spectabilis and G. mellonella also caused a decrease (p < 0.05) in the egg mass weight of R. microplus. The inhibition rate of egg-laying was greater than 80% for all treatments, reaching 92% in the treatment at a concentration of 800 EPNs/female, with nematodes reared in G. mellonella. We can conclude that, under laboratory conditions, the presence of another host did not reduce the activity of H. baujardi on R. microplus. Infective juvenile of entomopathogenic nematodes reared in M. spectabilis or G. mellonella have similar virulence against R. microplus engorged females.

In this work, lovegrass (Cpa), an abundant grass of the Poaceae family, was employed as feedstock for the production of activated carbon in a conventional furnace using ZnCl2 as a chemical activator. The prepared material (Cpa-AC) was characterized by pH of the point of zero charges (pHpzc), Boehm?s titration method, CHN/O elemental analysis, ATR-FTIR,N2 adsorption/ desorption curves, and SEM. This carbon material was used for adsorption of acetylsalicylic acid (ASA) and sodium diclofenac (DFC). FTIR analysis identified the presence of O-H, N-H, O-C=O), C-O, and aromatic ring bulk and surface of (Cpa-AC) adsorbent. The quantification of the surface functional groups showed the presence of a large amount of acidic functional groups on the surface of the carbon material. The isotherms of adsorption and desorption of N2 confirm that the Cpa-AC adsorbent is mesopore material with a large surface area of 1040 m2 g−1. SEM results showed that the surface of Cpa-AC is rugous. The kinetic study indicates that the system followed the pseudo-second-order model (pH 4.0). The equilibrium time was achieved at 45 (ASA) and 60 min (DCF). The Liu isotherm model best fitted the experimental data. The maxima sorption capacities (Qmax) for ASA and DFC at 25 °C were 221.7 mg g−1 and 312.4 mg g−1, respectively. The primary mechanism of ASA and DFC adsorption was justified considering electrostatic interactions and π-π interactions between the Cpa-AC and the adsorbate from the solution. Keywords Lovegrass .
