Beet armyworm (Spodoptera exigua) resistance to spinosad

Pest Management Science, 2000
Susceptibility to spinosad (Success®/Tracer®) of beet armyworm (Spodoptera exigua) from the southern USA and Southeast Asia was determined through exposure of second- and third-instar larvae to dipped cotton leaves. LC50 estimates of susceptibility of second- and third-instar larvae of field populations ranged from 0.279 to 6.14 and 0.589 to 14.0 mg ...

Biological activity of recombinant Spodoptera exigua multicapsid nucleopolyhedrovirus against Spodoptera exigua larvae

Biological Control, 2010
Abstract In this study the potency and efficacy of recombinant Spodoptera exigua multicapsid nucleopolyhedrovirus (SeXD1) were compared with that of the wild-type S. exigua virus (wt-SeMNPV). Time–dose–mortality bioassays of SeXD1 and wt-SeMNPV were conducted on 2nd to 5th instars of S. exiuga larvae. The results show that the recombinant SeXD1

Interactive Effects of Steinernema carpocapsae and Spodoptera exigua Nuclear Polyhedrosis Virus on Spodoptera exigua Larvae

Journal of Invertebrate Pathology, 1995
Abstract Laboratory experiments were conducted to assess the interactive effect of the entomopathogenic nematode Steinernema carpocapsae and Spodoptera exigua multinucleocapsid nuclear polyhedrosis virus (SeMNPV) when applied in combination against the beet armyworm, Spodoptera exigua , larvae on soybean.

Biological activity of Spodoptera exigua nuclear polyhedrosis virus against S. exigua larvae

Journal of Invertebrate Pathology, 1988
Abstract The peroral bioassay described by P. R. Hughes and H. A. Wood (J. Invertebr. Pathol., 37, 154–159, 1981) for neonate noctuid larvae proved to be useful and convenient for determining the biological activity of Spodoptera exigua nuclear polyhedrosis virus (SeMNPV) against all five beet armyworm instars. The LD50 values were 4, 3, 39, 102, and
