| Abstract | The fertility of hybrids from two distinct populations of Amblyomma cajennense from different ecological regions of Northern Argentina was analyzed. Two colonies of A. cajennense from El Rey National Park (RNP), Salta Province (24º41′S, 64º36′W), and Copo National Park (CNP), Santiago del Estero Province (25º55′S, 61º43′W) were established infesting rabbits with adults collected from vegetation. Reproductive parameters of the first generation in laboratory of each colony and their crosses were evaluated considering engorged weight of females, engorged period of females, pre-oviposition period of females, minimum egg incubation period, reproductive efficiency index [REI = number of eggs laid/weight of the females in mg], and fertility efficiency index [FEI = number of hatched larvae/weight of the females in mg]. Infestations were made as follows: Group 1) RNP males and females; Group 2) CNP males and females; Group 3) males from CNP and females from RNP; Group 4) males from RNP and females from CNP. The engorgement weight of the females from CNP that mated with males from RNP was significantly lighter than those of the engorged females obtained in the other 3 crosses, and the engorged period of the females from CNP that mated with males from RNP was significantly longer that the engorged period of the females belonging to the remaining groups. The females from group 3 and 4 had a FEI extremely low in comparison with the FEI obtained from the engorged females originated from the groups 1 and 2. Biological implication of these findings is discussed. |

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.
