Seasonal Lipid Content Of Bagworm Larvae, E. A. Heinrichs
Seasonal Lipid Content Of Bagworm Larvae, E. A. Heinrichs
Department of Entomology: Faculty Publications
It is common knowledge to many who have attempted to control bagworms Thyridopteryx sp., that early instars are fairly easy to control, while later larval stages are less susceptible to insecticides. Studies of other insects (Bennett and Thomas 1963, Munson and Gottlieb 1953, Munson et al. 1954, Reier et al. 1953) have shown that as the lipid content increases, the susceptibility to insecticides (especially chlorinated hydrocarbons) decreases. To determine whether the lipid content of the bagworm larva increased with age a series of lipid extractions was conducted.
Differential Plant Injury And Yield Responses Of Tomato Varieties To 2,4-D, D. P. Coyne, O. C. Burnside
Differential Plant Injury And Yield Responses Of Tomato Varieties To 2,4-D, D. P. Coyne, O. C. Burnside
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Experiments reported in this bulletin were conducted to determine the extent of plant injury and yield loss due to high and low rates of 2,4-D sprays on a wide range of home garden and processing tomato varieties. Results of this study could be used as a basis for suggesting tomato varieties suitable for growing in areas where 2,4-D drift is a common problem. An experiment was also conducted to determine if there was resistance to or good recovery from 2,4-D injury in other tomato species and in a wide collection of tomato plant introductions.
