Abstract

An extensive survey of the nemic fauna associated with 7 cereals, 14 vegetables, 16 fruits and 13 other crops of Pakistan was carried out. From over 6000 soil and plant samples screened from 39 districts of the country, a total of 46 genera and 153 species of nematodes were detected. Of these 19 genera and 97 species are new reports from Pakistan which includes a new genus and 18 new species as new to science. Description of a new genus Paktylenchus 1983 and nine species viz., Paktylenchus tuberosus Maqbool, 1983, Aglenchus mardanensis Maqbool, 1984, Quinisulcius solani Maqbool, 1982, Merlinius niazae Maqbool, 1983, Orientylus karachiensis Maqbool, 1984, Paurodontella sohailai Maqbool, 1982, Nothotylenchus goldeni Maqbool 1982, Boleodorus zaini Maqbool, 1982 and Hemicriconemoides ghaffari Maqbool, 1982 was published during the course of this study for the sake of priority. Description of the remaining nine species viz., Malenchus pakistanesis n.sp., M. nausheriensis n.sp., Leipotylenchus amiri n.sp., Neopsilenchus vulgaris n.sp., Dolichorhynchus tuberosus n.sp., and Criconemella anastomoides n.sp., Dolichorhynchus tuberosus n.sp., and Criconemella anastomoides n.sp. are presented herein. A new subfamily Triliniinae in the family Tylenchorhynchidae is also described Detailed studies on Quinisulcius solani was carried out. Q. solani showed an increase in population when inoculated on potato, tomato, egg plant, citrus and sugarcane and a decline in number in chillies, cotton, onion, okara, papaya, redish, tobacco and turnip suggesting their non host nature. Highest population of Q. solani was detected around potato roots upto 20-25 cm depth and at a distance of 20 cm from the base of the plant. Similarly sandy clay and a moisture levelof the plant. Similarly sandy clay and a moisture levelof the plant. Similarly sandy clay and a moisture levelof the plant. Similarly sandy clay and a moisture levelof the plant. Similarly sandy clay and a moisture level of 50% was conducive for the multiplication of Q. solani. Only one application of Aldicarb and carbofuran @ of 2kg a.i/ha as pre plant treatment was effective in reducing population of Q. solani from soil
