Abstract:
Two populations of HSW, one from Saltillo Coah. which is considered an insecticide-free area and one from Parras, Coah, in which 4-6 treatments are used each yr. The Parras population was collected from an area where 93.8% of the orchards are exposed to Guthion and 93% to Zolone, but have not been exposed to carbaryl for 5 yr. Third instar larvae (avg. wt 15 ±3 mg) were placed in treated vials (35 ml) for exposure to a range of insecticide doses. Doses in series and an acetone check were used or each insecticide with 5 larvae/vial/dose with 4 replicates; vials were held at 25±2°C and a photoperiod of 14:10 (L:D). Mortality was recorded after 24 h, corrected and data were analyzed using probits and the maximum likehood method. LD50 and LD95 values are reported.
