Download or read book Efficacy of Single Applications of Bacillus Thuringiensis and Diflubenzuron Formulations Against the Hemlock Looper in Newfoundland in 1988 written by Richard J. West and published by St. John's : Forestry Canada, Newfoundland & Labrador Region. This book was released on 1992 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diflubenzuron is a benzoylphenyl urea that upon ingestion by insect larvae selectively inhibits chitin synthesis. Double applications of Dimilin WP in aqueous formulations have reduced numbers of hemlock looper larvae and pupae significantly, although the foliage protection has been below 50%. It was suggested that the use of oil rather than water as a base for the diflubenzuron formulations might improve spray deposit and efficacy. This paper reports the results of field trials carried out in 1988 to evaluate the effectiveness of single applications of three formulations of Bacillus thuringiensis, Dipel 176, Dipel 264, and Futura XLV, and one oil-based formulation, Dimilin ODC. The applications of Dipel 176 and Dipel 264, both oil-based, were made against the hemlock looper at several stages in larval development whereas Futura XLV, a water-based formulation, was tested only once when the majority of larvae were in their second instar. The diflubenzuron applications were made against first-instar larvae.

Raske and published by St. John's : Newfoundland Forestry Centre. This book was released on 1987 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: An insect growth regulator, diflubenzuron, and an organophosphorous insecticide, fenitrothion, were tested against the eastern hemlock looper in western Newfoundland in July 1986. A 25% wettable powder formulation of diflubenzuron was sprayed as well as two different formulations of fenitrothion. The two insecticides were then compared.

This book was released on 1986 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hemlock looper is a very destructive defoliator of balsam fir in Newfoundland and has reached outbreak levels periodically since the turn ofthe century, with the latest being 1967-71. Populations of hemlock looperhave progressively increased since 1981 with a concomitant decline in numbersof the spruce budworm. This report presents the results of experimentalaerial sprays of various dosages or formulations of Matacil, Sumithion,Bacillus Thuringiensis, and Dimilin applied to early and mid-instar hemlock looper larvae near Bayd'Espoir in 1985.
