Sublethal Effects of Flonicamid on Life Table of Myzus persicae (Sulzer)

The green peach aphid, Myzus persicae (Sulzer) (Aphididae: Hemiptera) is a cosmopolitan polyphagous pest of more than five hundred plant species belonging to at least forty different families including several economically important agricultural crops. sublethal effect LC25 concentration flonicamid on M. was assessed by using an age-stage two-sex life table approach for integrated management this pest. A leaf-dip bioassay showed that very toxic the adults 48 h with calculated value 0.0115 g a.i./L. (parental generation) exposed (sublethal dose) inhibitory effects history traits across its generations such as reduction in adult longevity and fecundity parental generation (F0); shortening durations fifth instar nymphs, female longevity, oviposition period, total F1 & F2 generations. On other hand, stimulatory were observed duration first, second, third, fourth nymphs; pre-adults flonicamid-treated aphids. Consistently individual traits, higher mean time (T) shorter intrinsic rate increase (r), finite (λ), net reproductive (R0) treated aphids, although r, λ, R0, T, gross (GRR) not significantly affected. findings revealed exposure could induce hormetic (both stimulatory) their succeeding This study useful assessing overall persicae. should be considered when it used crop fields.
