Differential Performance of Beet Armyworm and Cabbage Looper (Lepidoptera: Noctuidae) Larvae on Selected Apium graveolens Cultivars
Three Apium graveolens (L.) varieties and cultivars within varieties were evaluated for host plant suitability to two polyphagous lepidopteran herbivores: the beet armyworm, Spodoptera exigua (Hiibner), and the cabbage looper, Trichoplusia ni (Hiibner). Overall, there were no significant differences in survivorship, developmental time, and pupal weight of S. exigua or T. ni reared on the two va...

متن کاملLaboratory Biology of Chetogena Scutellaris (diptera: Tachinidae), a Parasitoid of Noctuidae, Reared on Fall Armyworm and Cabbage Looper
The tachinid parasitoid Chetogena scutellaris (Wulp) was reared from southern armyworm, Spodoptera eridania (Cramer), a new host record. When reared in cabbage looper, Trichoplusia ni (Hübner), (a new host) and in fall armyworm, Spodoptera frugiperda (J. E. Smith), in the laboratory, C. scutellaris developed successfully ca. 30% of the time. Success of parasitism depended on the numbers of eggs...
متن کاملEfficacy of oxamyl against Heterodera schachtii on cabbage.
The efficacy of oxamyl in controlling Heterodera schachtii on cabbage was determined by applying various contbinations of soil drenches at 6.7 kg (a.i.)/ha and foliar sprays at 0.04 kg (a.i.)/100 liters of water to cabbage seedlings. Pretransplant drenches provided some control of H. schachtii over a 13-week period. A single foliar spray of oxamyl 1 week before transplanting apparently prevente...
متن کاملComparative virulence of Beauveria bassiana isolates against lepidopteran pests of vegetable crops.
Forty-three isolates of the entomopathogenic fungus Beauveria bassiana were screened for virulence against second-instar larvae of diamondback moth (Plutella xylostella) (DBM), European corn borer (Ostrinia nubilalis) (ECB), corn earworm (Helicoverpa zea) (CEW), and fall armyworm (Spodoptera frugiperda) (FAW); 30 of these isolates were tested against beet armyworm (Spodoptera exigua) (BAW). Hig...
