Pesticide Bioassays With Arthropods
POLO: A New Computer Program for Probit Analysis
Probit analysis has been widely used for many years to analyze bioassay data, including the response of insects to insecticides. The computations are very laborious, however, and much early research…

I began reading this volume thinking that my review might be biased. I had selected a systematics text from the stack: I do not like systematics texts, which seem so dry and boring. What a welcome…
Bioassays with Arthropods
Resistance of diamondback moth (Lepidoptera : Plutellidae) to Bacillus thuringiensis subspecies in the field
If B. thuringiensis is to remain a durable insecticide in parts of the world where resistance does not already occur, other tactics such as biological control, host-free periods, plant resistance, and cultural controls must he incorporated into the management programs.
Critical evaluation of the modified-adult immersion test with discriminating dose bioassay for Boophilus microplus using American and Australian isolates.
Effects of Dose Selection and Sample Size on the Precision of Lethal Dose Estimates in Dose–Mortality Regression
As a guide to experimental design for bioassays, the effects of total sample size and dose selection on the precision of LD50 and LD90 estimates were determined by Monte Carlo simulations with the…
Natural Variation: A Complicating Factor in Bioassays with Chemical and Microbial Pesticides
The conventional practice of using ratios of one LC to another in studies to detect resistance and other biological changes may lead to erroneous conclusions if natural variation in cohorts of a population and subsequent generations of the same genetic strain are unknown.
Colorado potato beetle (Coleoptera: Chrysomelidae): Effects of combinations of Beauveria bassiana with insecticides
In field cage tests of B. bassiana + insecticide, mortalities were generally greater than those caused by the individual agents, but synergistic interaction was not apparent, indicating that the two treatments were additive.
Statistical Analysis of Modes of Inheritance for Pesticide Resistance
The procedure includes the use of a modified x2 statistic that is appropriate for the analysis of bioassay data with extra sources of variation between replicates at the same dose.
