The Influence Of Edaphological Factors On The Biological Activity Of Selected Insecticides In Agricultural Soils, Bruce John Monke
The Influence Of Edaphological Factors On The Biological Activity Of Selected Insecticides In Agricultural Soils, Bruce John Monke
Department of Entomology: Dissertations, Theses, and Student Research
A rating system was developed to predict the mortality of southern corn rootworm (Diabrotica undecimpunctata howardi Barber) larvae used as test animals to bioasaay soil insecticides. The mortality probabilities, based on behavior of moribund larvae, resulted in data that was more consistent with the assumptions underlying parameteric statistics and provided more precision when compared to the usually accepted alternate method of considering moribund larvae as dead.
The rating system bioassay technique was used to study the effects of different soil factors on the relative decline in biological activity of six soil insecticides: carbofuran, chlorpyrifos, fonofos, isofenphos, phorate, and terbufos. …
