Distribution and sampling of southwestern corn borer (Lepidoptera: Pyralidae) in preharvest corn

Southwestern corn borer, Diatraea grandiosella Dyar, was sampled from six corn, Zea mays (L.), fields in the Texas High Plains during 1985, 1986, and 1987. Density estimates were made for eggs, small, medium, and large-sized larvae and pupae during both corn borer generations. Taylor's power fu...

Summary:Southwestern corn borer, Diatraea grandiosella Dyar, was sampled from six corn, Zea mays (L.), fields in the Texas High Plains during 1985, 1986, and 1987. Density estimates were made for eggs, small, medium, and large-sized larvae and pupae during both corn borer generations. Taylor's power function provided significant regressions for all size categories. The distribution of southwestern corn borer eggs and small larvae was aggregated. and older stages were progressively less clumped. Binomial and sequential sampling plans for eggs and small larvae were developed using Taylor's coefficients
