Field studies during 1986–1988 in southwestern Michigan showed that horse-nettle, Solanum carolinense L., could be an important reservoir of Colorado potato beetle, Leptinotarsa decemlineata (Say), populations when potatoes, Solanum tuberosum L., a

A simulation model is used to examine the errors in estimating parasitized and nonparasitized host densities independently with Southwood's graphical technique. This technique is accurate when parasitoid attack occurs prior to the sampling period (e.

The polyphagous coccinellid Coleomegilla maculate DeGeer fed on eggs and small larvae of the Colorado potato beetle, Leptinotarsa decemlineata (Say). Prey consumption rates were highly correlated with temperature. This predator did not prefer aphids

A compact, all-permanent-magnet, single-frequency electron cyclotron resonance (ECR) ion source with a large uniformly distributed ECR plasma volume has been designed and is presently under construction at the Oak Ridge National Laboratory. The centr

The white cutworm, Euxoa scandens (Riley), was studied in commercial asparagus fields between 1973 and 1975. Monitoring adult flight activity with a blacklight trap revealed that male moths were more attracted to the blacklight than females. Males we

The phenology and control of the onion maggot, Delia antiqua (Meigen) (Diptera: Anthomyiidae), were investigated in commercial onion fields in Michigan from 1978 to 1980. First-generation emergence of adults occurred at 399 Dδ (degree-days) (4.4°C

The systems approach, utilizing detailed system conceptualization and iterative simulation model development, was used to help direct field and laboratory research on the population dynamics of the onion maggot, Delia antiqua (Meigen) (Diptera: Antho
