| Summary: | applications, population data were collected for bookworm and its predators over two seasons. Life bookworm eggs in this system, although only a low but the largest portion of generational mortality was consumed bookworm eggs. The life tables for both cotton not receiving in-season insecticide feeders. Other common egg predators encountered were generational mortality was over 98%. Analysis by ELISA hatch accounted for 9.0 and 6.4% of the egg mortality Hippodamia convergens (Guerin-Meneville), and several immunosorbent assay (ELISA) to determine the instar life stages. Egg parasitism was primarily by of Orius spp. indicated that Orius does prey upon on bookworm, Helicoverpa zea (Boddie), in short season over 93% of the cohort dying in the egg and first predator, Orius spp., was assayed by enzyme-linked proportion of Orius sampled were deeded as egg proportion of the Orius spp. population that had Pseudatomoscelis seriates (Reuter), Scymnus spp., seasons revealed a type III survivorship curve with species of spiders. tables were construed for bookworm. An important egg the age-specific mortality of the egg. Failure to the residual and was not accountable. Overall To better understand the elects of natural mortality phics.
