Occurrence of Mistletoes and Their Hosts in and Around Rajshahi City, Bangladesh

Mohammad Tarikul Hasan
Department of Botany, Abdulpur Government College, Natore, Bangladesh

Abstract/ Executive Summary:

Mistletoes are a unique group of parasitic flowering angiosperm and can victimize a large number of woody plants. In the study area, a total 62 flowering species were found parasitized by only three mistletoes such as Dendrophthoe falcata (L.f.) Ettingsh., Macrosolen cochinchinensis (Lour.) Tiegh. and Scurrula pulverulenta (Wall.) G. Don. Among the infested plant species 51 were tree, 10 were shrub and only one was woody climber and all were dicotyledons, no herbaceous and monocotyledons were found. Dendrophthoe falcata (L.f.) Ettingsh. was observed frequently than others and 56 plants were found infested by it. Mistletoes are harmful for our valuable fruits, timber and ornamental tree as well as shrubs and climbers. Therefore we should be aware of it to protect our plants.

Objectives:

But a list of other taxon of mistletoes and their hosts occurring in Rajshahi is much wanting. Thus the present study was aimed to enumerate mistletoes and their hosts in and around the Rajshahi City which will be helpful for the researcher.

Methodology:

Study Area Rajshahi City is located in between 24'20'' and 24'24'' north latitudes and in between 88'32'' and 88'40'' east longitudes and the total area is 95.56 sq km. It is bounded by Paba upazila on all sides. Under Koppen climate classification, Rajshahi has a tropical wet and dry climate. The area comprises various types of plants such as the evergreen, semi-evergreen and also deciduas.

Floristic survey The present work was the outcome of extensive survey at different corners of the city and its surroundings from January 2019 to December 2020. Mistletoes are shrubby and bushy in nature and it is attached in an aerial parts of the host plant. As a result, presence of any hemiparasite on the host can easily visible. The mistletoes and host species were identified with the help of books; relevant literature and online flora. “Plants of the world online (http://www.plantsoftheworldonline.org)” was accessed for the taxonomic nomenclature of mistletoe and host species.

Achievement/Findings:

The current study has established a baseline study of mistletoe and their host in Rajshahi. A total 140 tree species had recorded from Rajshahi city fortunately all trees were not susceptible to mistletoes. This study has been observed that the plants in orchard or garden were less affected than the roadside or the scattered growing plants may be due to regular care or pruning. Consequently, not a single Moringa oleifera was found infested which had already been reported as a host. It may be due to regular cutting after harvest which is a normal practice of the people of the Rajshahi. This indicated plant-parasitic infestations can be controlled by regular care.
