SHORT COMMUNICATIONS IRFAN AHMAD1) & M. SHAMIM JAIRAJPURI2): : Sex attraction in ageing Chilo- placus symmetricus. Ageing in nematodes produces not only morphological but also physiological and behavioural changes. In the present work, the effects of age and reproduc- tive state of the males and females of Chiloplacus symmetricus (Thorne, 1925) Thorne, 1930 on sexual attraction were observed. The sexes were kept separate after the fourth moult for 1, 4, 8 or 12 days in malt-peptone agar. Sex attraction was tested in modified mickey mouse chambers (Ahmad & Jairajpuri, 1980b) using 1 % water agar. 50 females were introduced into the test chamber and 24 hr later 50 males were released in the inoculation chamber and the distribution of the males was recorded after 4 hr. Significance tests (Students t) were carried out between the number of males in the test chamber and the number in the control chamber. The following four combinations were tested: virgin males to virgin females; virgin males to non- virgin females; non-virgin males to virgin females and non-virgin males to non-virgin females. Each set of combinations was replicated five times. Sex attraction in C. symmetricus depended on age as well as the reproductive
