| Popis: | Inheritance of monocrotophos resistance was studied in the laboratory population of T. chilonis. After 10 cycles of selection pressure under laboratory condition, the resistant strain acquired LC50 value of 0.346mL compared toLC50 value of 0.114 mL in the susceptible strain. Evidence from bioassay of F1 reciprocal hybrid crosses backcrossed with respective resistant 'R' and susceptible 'S'parentalstrains of T. chilonis, aimed to determine mode of inheritance of insecticide tolerance indicated that F1 crosses exhibited a complete dominant response to monocrotophos, with degree of dominance value (D) of 1.62. The resistance factor (Rf) of resistant strain was 3.04 folds and of F1 crosses were 3.675 folds over susceptible strain. Result of this study suggests resistance to the insecticide was probably controlled by a single gene. These results provide the basic information for designing successful management programmes for the control of Lepidopteran pests using resistant strain as a component of IPM. |
