	Ecology: Plant hybrid zones and insect host range expansion - Hybridization and Resistance to Parasites
		Floate and Whitham (1993) suggest that this is because the genetic gap between the host and the [F.sub.1] is large relative to the two smaller genetic gaps: (1) between the parent and the BC, and (2) between the BC and the [F.sub.1].
		The first is that phenotypic gaps between actual and potential hosts limit host range in herbivorous insects and mites, and the second is that the genetic control of characters controlling host use is additive in all types of hybrids.
		Host range expansion onto hybrids, like range expansion onto novel hosts, must be controlled by relative differences in preference and performance on the ancestral and novel hosts.

		If you were to draw an analogy between host range of insect parasites and the diet of my two children, Brussels sprouts are in their potential host range, yet are not in their realized host range.
		Avoiding the host's immune system is what makes the interaction between internal parasites and their hosts very intimate, and what also limits the hosts that can be attacked successfully.
		Host range in the laboratory will nearly always be greater than that measured in the field.

	HOST SPECIFICITY
		Mermithids of terrestrial insects have a broader host range than those that parasitize aquatic insects.
		Host range is more restricted in aquatic mermithids, often to a single or a few species of closely related hosts.
		Further, mermithids that complete their parasitic development only in adult hosts are usually specific for a single host species (P. culicus for Aedes sollicitans, Culicimermis culcivora for Aedes communes, Empidomermis cozii for Anophelesfunestus, and Empidomermis riouxi for Aedes detritus).

		Louda (1998) has documented the expansion of this weevil's host range into two native Cirsium thistles in Nebraska, and she has shown through long term studies that seedling recruitment in populations of these non-targets is limited by seed predation (Louda & Potvin 1995).
		In defense of those involved with this program, it should be noted that the broad host range of R. conicus was well known at the time of introduction (1969), but that in those days, impact to native plants (particularly native thistles!) was not considered to be a problem.
		Host tests indicated that L. jacobaeae has a narrow host range, and we are unlikely to find it on plants other than a couple of very close relatives, also introductions from Europe.

		The host range of ectomycorrhizal (ECM) fungi in Britain was examined by compilation of a data matrix from published literature sources, based primarily on accounts of sporocarp associations with particular host genera.
		There was also variation in the number of species of ECM fungi which were apparently specific to particular host genera, values ranging from zero tin 15 general to > 40 in the case of Betula and Fagus.
		Comparison of the ECM mycota associated with different host genera by PCA accounted for 17 % of the total variation, with genera belonging to the Fagaceae (Quercus, Fagus and Castanea) tending to cluster together, indicating a degree of overlap in their ECM associates.

		The designation FK1-5 denotes the phage's ability to infect E. coli strains that contain the K1 polysaccharide in their outer capsule as well as E. coli strains that contain the K5 polysaccharide in their outer capsule.
		Sequence analysis of the tail proteins of phage FK1-5 by the inventors has shown that they are arranged in a cassette structure, suggesting that the host range of phages can be broadened to other K antigens, and even possibly other species of bacteria by recombinant techniques.
		The inventors' demonstration that a phage can contain multiple tail proteins that expand its host range is useful for generating phage with broad-spectrum antibacterial properties for the treatment of infectious diseases.

	ARS \| Publication request: Salmonella Host Range of Bacteriophages Which Exhibit Increased Host Range
		For determination of host specificity, a pool of 44 combined isolates of phages were evaluated for ability to propagate in individual non-pathogenic enteric bacterial isolates.
		Amplification in each species was confirmed by the formation of increased pfu's in a TSA overlay with the enteric (alternative host) bacteria.
		These experiments suggest that phage host range is not always genera-restricted, and that selection of subpopulations of phages, capable of amplification in alternative genera, may provide a tool for selection of broad host-range phages for the pathogen of interest.

		Specialist parasitoids are assumed to use more specific information about their hosts than generalist parasitoids.
		However, when A. tabida females were given an oviposition experience in the presence of host pheromones, they became attracted to aggregation pheromones of their host.
