Notes
Juveniles of Caenorhabditis elegans were transformed to dumpty in the media containing methomyl (10 ug/ml) of aldoxycarb (500 ug/ml), but not in the media containing methyl-isothiocyanate (MITC). The dumpty did not recover to its normal structure even after being transferred to fresh medium, but underwent to adulthood with a lower reproduction rate. The progeny form the dumpty forms was normal in structure, however, its reproductivity was as low as one-third of normal worms. Longevity of the dumpty form and its progeny were longer than those of normal worms. Methomyl (1 ug/ml), MITC (1 ug/ml) and aldoxycarb (10 ug/ml) did not suppress population growth, but MITC (10 ug/ml) did for the first two weeks. The population growth was markedly suppressed at 100 ug/ml of methomyl, 20 ug/ml of MITC and 1000 ug/ml of aldoxycarb.
