Biological control of Common reed (Phragmites australis) and Flowering rush (Butomus umbellatus)
Abstract
The major objectives of this project is to undertake biological research to develop the understanding about how to maintain rearing of the two moth species Archanara geminipuncta and A. neurica in view of future field releases in North America. In mid-April, newly hatching larvae will be transferred into cut stem pieces of common reed. Stem sections will be placed onto moist horticultural sponges in transparent plastic cylinders with a gauze lid. When larvae leave the first stem sections, they will need to be transferred into new stems, and this 3-4 times until pupation. Emerging adults will be mated and placed for oviposition in wooden cages with stem bases of common reed. Eggs can then be collected on the leaf sheaths of the stems. Eggs are being overwintered in tight closing Petri dishes until the following year. Continue to improve the rearing of B. nodulosus at the Centre; repeat impact experiment with B. nodulosus using a modified method; complete host range testing with B. nodulosus and contribute to the preparation of a petition for field release; establish a rearing colony of B. validus, study it’s biology and start with preliminary host range tests; obtain more specimens of the flies Phytoliriomyza ornata and Hydrellia concolor and study their biology and phenology; extend surveys to cover new areas (e.g. France, UK, Georgia) and identify additional potential biocontrol agents. The proposed work will provide a timely contribution to the ERDC mission because this CABI research supports the Environmental and Navigation Business areas; specifically, the Aquatic Plant Control Research Program (APCRP). This program develops new technologies for managing aquatic weed infestations of major economic significance, or weed infestations that have, or potentially may reach such economic significance, in navigable waters, tributaries, streams and connecting channels and all allied waters.
