Abstract
ADULTS of Drosophila spp. trapped at frequent intervals in Nature at Dalkeith, Midlothian, were dissected to follow the development of the ovaries, and occasionally the testes, during autumn, winter and spring. The flies dissected were D. subobscura Coll. (19 males, 338 females), D. obscura Fin. (17 males, 92 females), D. silvestris Bas. (41 males, 34 females), D. tristis Fln. (2 males, 7 females), D. funebris (Fabr.) (3 males, 11 females), and D. cameraria Hal. (3 females). During these dissections a few specimens of the first three species were observed to be infested with a nematode, provisionally identified as Aphelenchulus sp. (Allantonematidae Chtw. and Chtw., 1937), probably new. The numbers of dissected flies are shown in Table 1, the figures in parentheses being the numbers of those infested.
