Control of Invasive Soybean Aphid, Aphis glycines (Hemiptera: Aphididae), Populations by Existing Natural Enemies in New York State, with Emphasis on Entomopathogenic Fungi
Abstract This study evaluated the diversity and abundance of existing natural enemies of soybean aphid, Aphis glycines L., under field conditions in New York State, with emphasis on entomopathogenicExpand
Distribution and Abundance of Carabidae (Coleoptera) Associated with Soybean Aphid (Hemiptera: Aphididae) Populations in Central New York
A significant negative exponential relationship described this relationship between activity density of carabids and aphid density and it was confirmed that the dominant species A. muelleri readily eats soybean aphids, which is consistent with carabid predation on Soybean aphid populations. Expand
Characterization of aphid pathogenic species in the genus Pandora by PCR techniques and digital image analysis
Digital image analysis was employed for the first time for entomopathogenic fungi results agreed with the genetic analysis by combining digital image analysis and information on host insect species. Expand
Putative source of the invasive Sirex noctilio fungal symbiont, Amylostereum areolatum, in the eastern United States and its association with native siricid woodwasps.
Two genotypes of the fungal symbiont Amylostereum areolatum are associated with the invasive woodwasp Sirex noctilio, and nucleotide sequence data from the intergenic spacer region (IGS) of the nuclear ribosomal DNA shows genotypes found in North America are most similar to genotype found in Europe, and not to genotypes from the southern hemisphere.

Soil as an environment for winter survival of aphid-pathogenic Entomophthorales
Morphological studies of the inoculum suggest that P. neoaphidis may survive unfavorable conditions as thick-walled conidia also known as loricoconidia, and hypothesize that germination of overwintering inoculum is stimulated by host-induced factors since inoculum apparently responded to the presence of aphids.

Ants defend aphids against lethal disease
These results extend the long-standing view of ants as mutualists and protectors of aphids by demonstrating focused sanitizing and quarantining behaviour that may lead to reduced disease transmission in aphid colonies. Expand
Little evidence for negative effects of an invasive alien plant on pollinator services
Overall there is little evidence for negative effects of the invasive species on pollination of neighbouring plants, and flower visitation even increases close to the invaded patches, and the functional role of the invader and suitable control strategies need further clarification. Expand
Fidelity Among Sirex Woodwasps and Their Fungal Symbionts
It is reported that associations between mutualistic fungi and their economically and ecologically important woodwasp hosts are not always specific as was previously assumed, and the hypothesis of strict species-specific relationships is refuted. Expand
