An Assessment of Gypsy Moth Eradication Attempts in Michigan (Lepidoptera: Lymantriidae)

Michigan\u27s infestation of gypsy moth, Lymantria dispar, extends over 600,000 acres, First discovered in Michigan in the 19505, gypsy moth was reportedly eradicated through the use of DDT then reintroduced in the 1970s, Substantial circumstantial biological evidence, however, points to the probability that gypsy moth has resided continuously in Michigan for over 30 years, Environmental factors may be largely responsible for containing Michigan\u27s gypsy moth popUlations

Flower Associations of Mimetic Syrphidae (Diptera) in Northern Michigan

Collections of specialized (high fidelity) mimetic Syrphidae in northern Michigan revealed 19 species associated with 18 flowering plants. Almost 97% of these syrphids were taken on seven plant species or species groups, all with conspicuous white or yellow blossoms, and all but one with aggregate inflorescences. Pastinaca sativa (Umbelliferae) is visited by many mimetic syrphids in northern Michigan but by very few in central Illinois; the opposite is true of Sambucus canadensis (Caprifoliaceae). In northern Michigan mimetic syrphids exploit a sequence of blossoming plants that more or less replace each other as the season progresses. The cooling effect of Lake Michigan slows the development of vegetation and the appearance of mimetic. syrphids along the shore by over two weeks as compared to a transect only 6.5 to 17 km inland. Because of the normally cooler temperatures in northern Michigan, syrphids appear on flowers later in the day and remain there longer than they do in central Illinois

A comparison between the Pittsburgh and Michigan approaches for the binary PSO algorithm

IEEE Congress on Evolutionary Computation. Edimburgo, 5 september 2005This paper shows the performance of the binary PSO algorithm as a classification system. These systems are classified in two different perspectives: the Pittsburgh and the Michigan approaches. In order to implement the Michigan approach binary PSO algorithm, the standard PSO dynamic equations are modified, introducing a repulsive force to favor particle competition. A dynamic neighborhood, adapted to classification problems, is also defined. Both classifiers are tested using a reference set of problems, where both classifiers achieve better performance than many classification techniques. The Michigan PSO classifier shows clear advantages over the Pittsburgh one both in terms of success rate and speed. The Michigan PSO can also be generalized to the continuous version of the PSO

Biology of the Genus \u3ci\u3eHemileuca\u3c/i\u3e (Lepidoptera: Saturniidae) in Michigan

The habitats and host plants of buckmoths (Hemileuca: Saturniidae: Hernileucinae) in Michigan are described and compared to those of the three species known from eastern North America, H. maia, H. nevadensls, and H. lucina. Michigan populations show variation in host plant and habitat use spanning the entire range of all three species. The presence of transitional phenotypes and the host plant and habitat data suggest that Michigan populations are a single, variable species. These things combined with the intermediate geographical location of Michigan\u27s populations call into question the taxonomic distinctness of the three eastern buckmoth species
