Abstract

Beet armyworm, SPODOPTERA EXIGUA (Hubner), is an important pest of field crops with a wide range of host plants. Using safer insecticides, such as INSECT GROWTH REGULATORS (IGRs), with different modes of action and lower possibility of development of resistance would be useful for an effective control program. The effects of three IGRs namely METHOXYFENOZIDE, LUFENURON and FLUFENOXURON were assessed on 1st instar larvae of S. exigua. The bioassays were performed using diet incorporation and leaf dipping methods. Mortalities were recorded 144 hours after the treatment. The LC50 values for METHOXYFENOZIDE, FLUFENOXURON and LUFENURON were found to be 0.154, 0.254 and 2.398 mg ai/l, in diet incorporation method; and 1.302, 0.427and 3.510 mg ai/l in leaf dipping method, respectively. Based on the 95% confidence interval of the ratios of LC50s, for all of the insecticides tested, the LC50 values were significantly different in the two bioassay methods used. LUFENURON had the lowest toxicity against the 1st instars of beet armyworm in both assays. All insecticides were effective against 1st instar larvae of beet armyworm at low concentrations.
