This book was released on 1981 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of the evaluation of two species of insects for the biological control of Eurasian watermilfoil (Myriophyllum spicatum L.). One of the species is a native weevil, Litodactylus leucogaster (Marsh.), which attacks the flower spikes, and the other is an accidentally introduced European moth, Acentria nivea (Oliver), whose larvae feed on the leaves and stems. The biology of L. leucogaster was studied in detail and host-specificity tests were conducted with adults and larvae. Since it was determined to be specific to watermilfoils, it was released at Crystal River, Florida, on 22 August 1979. Two adults were captured at Crystal River in November indicating possible establishment. The pyralid moth, A. nivea, was difficult to rear in the laboratory. Since the females were active only one night, successful matings were rare in the small colony. Larval production was best in containers that were minimally disturbed. the larvae required water temperatures below 22 C for development though they could survive short periods at higher temperatures. The larvae were not specific to milfoil; however, A. nivea may still be of interest as a member of a complex of species which attack milfoil. (Author).

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic invasive plants present a growing risk to the environment and the economy. One of the most problematic invasive plants found in North American waterbodies is Eurasian watermilfoil, Myriophyllum spicatum. Eurasian watermilfoil was inadvertently introduced into Christina Lake, British Columbia, Canada, in the early 1980's. Physical control methods have been utilized since the plant was first identified in the Lake, but regular intensive management is required to meet control objectives. Variable success has been reported in Ontario lakes and waterbodies in the United States using the milfoil weevil, Euhrychiopsis lecontei as a biological control agent. Field sampling in Christina Lake indicated that the milfoil weevil is not currently present, or is present at numbers below detection. As an introductory stage of a potential biological control program, a Christina Lake-specific simulation model was developed to evaluate the expected response of milfoil growth to different weevil augmentation scenarios. Results of the model indicate that control of the sites most impacted by Eurasian watermilfoil could be achieved with a weevil augmentation rate of one weevil per square metre.

Available in PDF, EPUB and Kindle. Book excerpt: This technical note describes laboratory investigations conducted to evaluate the effectiveness of the herbicide fluridone (1-methyl-3-phenyl-5 3-(TRIFLUOROMETHYL)PHENYL-4(1H)-pyridinone) and the fungal pathogen Mt (Mycoleptodiscus terrestris (Gerd.) Ostazeski), applied alone and in combination with one another, against Eurasian watermilfoil (Myriophyllum spicatum L.). Results of this research will demonstrate the potential for integrating chemical and biological control tactics to improve the long-term management of nuisance aquatic weed species.

This book was released on 1988 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of the continental United States for pathogens of Myriophyllum spicatum (Eurasian watermilfoil) was conducted. More than 50 water bodies, located in 10 states, were sampled for diseased plants. Sample sites represented a geographic and climatic cross section of aquatic systems in the continental United States, including ponds, lakes, reservoirs, rivers, and canals. At the conclusion of the survey, 792 isolates had been collected from tissue samples and maintained in pure culture. Of these, 462 were bacteria and 330 were fungi; many isolates were duplicates but were retained because they possibly represented different strains of the same species. Lytic enzyme assays indicated that 14 bacterial and 22 fungal isolates produced pectinase or cellulose. Enzyme assays were used to screen for the more promising isolates for additional study as potential biocontrol agents for the management of Eurasian watermilfoil. The 32 isolates were then assayed healthy sprigs of the target species in test tubes. Results indicated that five fungal isolates should be considered for additional study. Keywords: Biological weed control; Aquatic weeds; Aquatic plants. (kt).

This book was released on 1983 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies reported previously have shown that inoculation of Myriophyllum spicatum and M. heterophyllum with enzyme-enhanced pectinolytic or cellulolytic microorganisms originally isolated from these species significantly accelerated plant necrosis. Subsequent studies, reported herein have attempted to assess plant response to inoculation under a variety of stress conditions, to define infection thresholds, and to enlarge the scale of infection trials.
