data of vouchered bees to test for differences between repeatedly sampled sites and single sample sites regarding abundance (as catch rate), rarefied richness, and evenness (as Evar).

data of combined bees (vouchered + released) to test for differences between repeatedly sampled sites and single sample sites regarding abundance (as catch rate), rarefied richness, and evenness (as Evar).

Aquatic insects have numerous adaptations reflecting the coevolution of predators and prey. Predators have a wide variety of search, capture, and consumption mechanisms, and prey demonstrate various physical, chemical, and behavioral defenses. Mortality in prey populations from predation may be sign

The success of the butterfly simulator in mimicking Colias thermal characteristics confirms the preliminary understanding of the physical bases for and heat transfer mechanisms underlying thermoregulatory adaptations in these butterflies.

I examined the response of bumblebees to two kinds of spatial variation and two kinds of temporal variation in nectar levels. The spatial variation involved differences in reward value among plant species and differences in nectar availability among patches of flowers of a single species. The tempor

The larvae of Glaucopsyche lygdamus (Lepidoptera: Lycaenidae) secrete substances that attract ants. In two field sites in Colorado, tending ants protect caterpillars of G. lygdamus from attack by braconid and tachinid parasitoids. This protection may have been an important feature in the evolution o

Key factor analysis techniques were used to examine factors determining the abundance of a population of non-pest Colias, finding factors resulting in reduced natality and mortality during larval diapause determine the population trends for C. alexandra.

Female use of nutrients donated by males at mating, and complete sperm precedence, in Colias eurytheme Boisduval are documented.

Abstract 'Pungo' Irish potatoes were planted on Mar 24, near Beaufort, NC. Single row plots 25-ft long were replicated 4 times in a randomized complete block design with 5-ft alleys between replications. Pretreatment counts of Colorado potato beetle were made by examining 3 plants/plot and recording

Abstract 'Superior' Irish potatoes were planted on Mar 29, near Benson, NC. Single row plots 7-ft long were replicated 4 times in a randomized complete block design with 2-ft alleys between replications. A pretreatment stand count and defoliation rating was made on May 15. Rating was based on 0 - no
