The main insect pests and diseases associated with Brachiaria pastures are considered, with emphasis on spittlebugs, the most damaging pests in tropical America. Outbreaks of the polyphagous burrowing bugs of the genus Scaptocoris, both in Brazil and Colombia, are of concern. Other pests discussed include leafcutting ants; the mound-building termites, Cornitermes cumulans and Syntermes sp.; the lepidopterans, Spodoptera frugiperda and Mocis latipes; the rhodesgrass scale, Antonina graminis; and the chinch bug, Blissus leucopterus. Important fungal and viral diseases of Brachiaria species are outlined. Most of these occur in Africa, the center of diversity of Brachiaria, but lately some particularly foliar blight caused by Rhizoctonia solani; ergot, caused byClaviceps specie; and guineagrass mosaic virus - have acquired importance in tropical America, and could become devastating where vast areas are planted to a single cultivar. Chemical control is not feasible in perennial pastures, and pest- and disease-resistant cultivars of Brachiaria need to be developed as a low-cost alternative. Promising control measures and future research needs are discussed. |

The aim of this study was to assess the activity of aqueous (AE) and ethanolic extracts (EE) and pilocarpine hydrochloride, which were extracted and isolated from Pilocarpus microphyllus (Jaborandi), respectively, on Rhipicephalus (Boophilus) microplus. High performance liquid chromatography (HPLC) was performed to quantify these compounds. Larval packet and adult immersion tests were conducted with different concentrations. Five AE and EE concentrations, ranging from 6.2 to 100.0 mg mL?1, and six concentrations of pilocarpine hydrochloride, ranging from 0.7 to 24.0 mg mL?1, were tested. The lethal concentration (LC50) of each extract for larvae and engorged females was calculated through Probit analysis. The concentration of pilocarpine hydrochloride obtained from the EE and the AE was 1.3 and 0.3% (m/m), respectively. Pilocarpine hydrochloride presented the highest acaricidal activity on larvae (LC50 2.6 mg mL?1) and engorged females (LC50 11.8 mg mL?1) of R.(B.) microplus, followed by the EE which presented LC50 of 56.4 and 15.9 mg mL?1, for larvae and engorged females, respectively. Such results indicate that pilocarpine hydrochloride has acaricidal activity, and may be the primary compound responsible for this activity by P. microphyllus EE. |
