| Abstract | The tick Boophilus microplus is the principal species of ectoparasite that impairs dairy cattle productivity in Brazil. Its control is mainly by using synthetic chemical products during its parasitic phase. The purpose of this study is to evaluate the acaricide activity of four products of natural origin. Depending on solubility, tests were conducted with solutions in distilled water or emulsified in aqueous DMSO at 1% of the following products: thymol, menthol, methyl salicylate, and salicylic acid. Each of these was tested at three concentrations (0.25, 0.5, and 1.0%) with five repetitions. The “larval packet test” was performed on approximately 100 larvae of B. microplus at around 15 days of age. After applying the test substances, the envelopes were kept at 27°C and UR >80% and opened after 24 h to count the living and dead larvae. Of the four products tested, only thymol caused significant (up to 100%) mortality of B. microplus larvae. The mortality caused by the other products varied from 0.52 to 9.76%. Hence, thymol can be considered a potential agent to control bovine ticks. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
