Qualitative Assessment of the Pharmacist’s Role in Punjab, Pakistan: Medical Practitioners’ Views

Purpose: To assess the perception of Pakistani doctors regarding pharmacist’s role in Punjab Pakistan.Methods: A qualitative approach was used to assess the perception of doctors regarding pharmacist’s role in the study setting. A total of 12 doctors were interviewed using a semi- structured interview guide. The study was conducted for a period of 3 months in the Pakistani cities of Islamabad and Lahore, from July to September 2011. Doctors were informed regarding the aim, objective and nature of the study.Results: All the interviews were transcribed verbatim and thematically analyzed for their content. Thematic content analysis yielded four major themes: 1) Availability of pharmacist in Pakistan’s healthcare setting. 2) Willingness to collaborate with pharmacist. 3) Separation of prescribing from dispensing. 4) Difference in academic levels of doctors and pharmacist.Conclusion: Doctors are receptive to an expanded role for pharmacists, also regard them as drug information experts, but their expectations fall short of the quality of clinically-focused pharmacy services that pharmacists are actually rendering.Keywords: Doctors’ expectation, Pharmacist, Clinical pharmacy services, Qualitative study, Prescribin

The importance of alternative host plants as reservoirs of the cotton leaf hopper, Amrasca devastans, and its natural enemies

Many agricultural pests can be harboured by alternative host plants but these can also harbour the pests’ natural enemies. We evaluated the capacity of non-cotton plant species (both naturally growing and cultivated) to function as alternative hosts for the cotton leaf hopper Amrasca devastans (Homoptera: Ciccadellidae) and its natural enemies. Forty-eight species harboured A. devastans. Twenty-four species were true breeding hosts, bearing both nymphal and adult A. devastans, the rest were incidental hosts. The crop Ricinus communis and the vegetables Abelmoschus esculentus and Solanum melongena had the highest potential for harbouring A. devastans and carrying it over into the seedling cotton crop. Natural enemies found on true alternative host plants were spiders, predatory insects (Chrysoperla carnea, Coccinellids, Orius spp. and Geocoris spp.) and two species of egg parasitoids (Arescon enocki and Anagrus sp.). Predators were found on 23 species of alternative host plants, especially R. communis. Parasitoids emerged from one crop species (R. communis) and three vegetable species; with 39 % of A. devastans parasitised. We conclude that the presence of alternative host plants provides both advantages and disadvantages to the cotton agro-ecosystem because they are a source of both natural enemy and pest species. To reduce damage by A. devastans, we recommend that weeds that harbour the pest should be removed, that cotton cultivation with R. communis, A. esculentus, and S. melongena should be avoided, that pesticides should be applied sparingly to cultivate alternative host plants and that cotton crops should be sown earlier
