Stochastic Simulation for Characterizing Ecological Spatial Patterns and Appraising Risk.
TLDR
The theory and a case study are presented for a class of techniques known as stochastic simulation that allows the environmental researcher, policy-maker, or manager the opportunity to characterize uncertainty and economic or other losses, and to determine areas requiring treatment and additional samples.

Field evaluation of several insecticides on Maricopa harvester ant (Hymenoptera: Formicidae) colony activity in fallow southwestern Arizona Cropland
TLDR
Investigation of efficacy of a single broadcast treatment at two rates of four insecticides on Maricopa harvester ant, Pogonomyrmex maricopa Wheeler, colony activity suggests that comparable reduction in colony activity may be attained if hydramethylnon is applied at a rate <9.68 g (AI)/ha. Expand
Within-Field Distribution Patterns of Tobacco and Tomato Hornworm (Lepidoptera: Sphingidae) Egg and Larval Populations in Southern Maryland Tobacco
TLDR
A truly random cluster sampling technique for assessing hornworm egg or larval population density is suggested and it is suggested that the size of the sample cluster be adjusted to vary with the parameter k of each hornworm population for maximum sampling efficiency. Expand
Maricopa Harvester Ant Control in Fallow Southwest Arizona Cropland
TLDR
It is concluded that maricopa harvester ants can be effectively controlled with amidinohydrozone and that a similar reduction in colony activity may be obtained if amidinhydrozone is broadcast at less than 1.0 lbs /A. Expand
