BIOLOGICAL CONTROLÐMICROBIALS Enhanced Activity of the Nucleopolyhedrovirus of the Fall Armyworm (Lepidoptera: Noctuidae) on Bt-Transgenic and Nontransgenic Sweet Corn with a Fluorescent Brightener and a Feeding Stimulant
نویسندگان
چکیده
The effects of a nutrient-based feeding stimulant, Coax, and a stilbene-based optical brightener, Blankophor P167, on the activity of the nucleopolyhedrovirus of the fall armyworm, Spodoptera frugiperda (J. E. Smith) (SfMNPV) on transgenic sweet corn, Zea mays L., expressing a CryIA(b) toxin from Bacillus thuringiensis (Berliner), were studied in the laboratory. Both Coax and Blankophor P167 increased virus-induced mortality. The effects of both materials did not differ between transgenicandnontransgeniccorn.Thegreatest increase invirus-inducedmortalityoccurred when Coax and Blankophor P167 were combined. Neither material affected the percentage of larvae killed by the CryIA(b) toxin.

Field corn, Zea mays L., plants expressing Cry1Ab and Cry1F insecticidal crystal (Cry) proteins of Bacillus thuringiensis (Bt) Berliner are planted on considerable acreage across the Southern region of the United States. The fall armyworm, Spodoptera frugiperda (J.E. Smith), is an economically important pest during the mid-to-late season on non-Bt and some commercial Bt corn hybrids. The object...

The gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae) nucleopolyhedrovirus LdMNPV was tested as a synergist for nucleopolyhedroviruses against Helicoverpa zea (Boddie), Spodoptera exigua (Hübner), and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) larvae. The addition of the gypsy moth NPV significantly decreased the LC50s of AcMNPV, AfMNPV, GmMNPV, HaMNPV, HzSNPV, PxMN...

Leaf-feeding damage by first generation larvae of fall armyworm, Spodopter frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), and southwestern corn borer, Diatraea grandiosella Dyar (Lepidoptera: Crambidae), cause major economic losses each year in maize, Zea mays L. A previous study identified quantitative trait loci (QTL) contributing to reduced leaf-feeding damage by these insects in the mai...

Growth and development of fall armyworm, Spodoptera frugiperda (J. E. Smith), were compared in two laboratory trials between individuals oered transgenic maize seedlings, conventional maize seedlings, or artificial diet. Transgenic maize seedlings in the first and second trials expressed Cry9C (Event CBH 351) and Cry1A(b) (Event MON 810) Bacillus thuringiensis (Berliner) (Bt) endotoxin genes, r...
