Abstract
The present paper deals with study of pollen analysis of four spider web samples, collected from the mixed teak deciduous forest near Rangaraopet village, karimnagar district. These spider webs, the natural pollen traps, were processed by using Erdtmans acetolysis technique (1960) and recovered pollen taxa viz., Acacia leucophloea, Acacia nilotica, Asteraceae type, Ailanthus excelsa, Alangium salviifolium, Alternanthera sessilis, Azadirachta indica, Butea monosperma, Ageratum conyzoides, Achyranthes aspera, Cleistanthus collinus, Chloroxylon swietenia, Chloroxylon swietenia, Capparis grandis, Calosanthes indica, Cassia fistula, Dillenia pentagyna, Diospyros dubia, Dolichandrone atrovirens, Feronia elephantum, Dodonaea viscosa, Gyrocarpus americanus, Grass, Holarrhena pubescens, Ixora arborea, Lannea grandis, Maytenus emarginata, Acacia farnesiana, Madhuca longifolia, Oldenlandia corymbosa, Phoenix sylvestris, Prosopis juliflora, Parthenium hysterophorus,Stachytarpheta indica, Syzygium cumini, Terminalia arjuna, Tectona grandis, Xanthium strumarium and Ziziphus mauritiana. The quantitative and qualitative analysis of palynological data reveals the dominance of arboresent plants. Hence the spider webs are functioning as air monitors which are useful for aeropalynological survey by trapped dispersed pollen in the spider webs of Rangaraopet village in Karimnagar district.
