Abstract
An experiment was conducted for the study of nematode infested flowers of tuberose from the tuberose growing areas of Gangetic plains of West Bengal to extract the population of Aphelenchoides besseyi. Surveys were conducted at Nokari (Ranaghat –II block of Nadia district); Gayeshpur (Chakdah block of Nadia district); Raghunathpur (Bhangar I block of South 24-Parganas district) and Deulia (Panshkura II block of Purba Medinipur district). For studying morphometric variability, the nematode specimens from each population were processed by glycerol-ethanol method and permanently mounted in pure anhydrous glycerol. Some variations in morphometric characters among populations were observed. In all the four populations of A. besseyi the ‘b’ ratio (7.8-11.5), stylet length (8.8- 11.9 μm), head height (2.1-2.9 μm), head width (5.6-6.9 μm), anal body width (8.4-10.1 μm) and V% (70.2-75.9) were observed as the least variable morphometric characters. Ratios like a, bʹ, c and cʹ and distance between vulva and anus were either least or moderately variable. Body length of A. besseyi was found least variable character except for the Deulia population where the mentioned character was moderately variable. Greatest body width was found to be very consistent character of A. besseyi in all the population except for the Nokari population. The study is important for formulating integrated management modules of foliar nematode. Tuberose bulbs are coated with turmeric and butter and pasted on infants’ red blemishes.
