Definitions

  • This invention relates to the use of a coleopteran active B. thuringiensis or its delta endotoxin in controlling the Western eucalyptus leaf beetle Chrysophtharta bimaculata, a method of controlling Chrysophtharta bimaculata by applying an effective amount of coleopteran active B. thuringiensis or its delta endotoxin to an area infested by Chrysophtharta bimaculata, and insecticidal compositions for controlling Chrysopht ⁇ hearta bimaculata.
  • Bacillus thuringiensis Commercial preparations of Bacillus thuringiensis are used worldwide for biological control of pest insects.
  • the advantages of these bacterial insecticides are that they are highly selective for a very limited range of target insects and are biodegradable.
  • Bacillus thuringiensis is a rod shaped, aerobic, spore forming bacterium uniquely characterized by the production during the sporulation process of one or more inclusions, referred to as parasporal crystals. These crystals are composed of high molecular weight proteins, referred to as delta-endotoxins.
  • the delta-endotoxins are the active ingredient in available commercial preparations of Bacillus thuringiensis.
  • B. thuringiensis strains with different insect host spectra have been identified. They are classified into different subspecies based on their flagellar antigens. Of particular interest is Bacillus thuringiensis subspecies kurstaki and subspecies aizawai used for the control of lepidopteran pest insects, Bacillus thuringiensis subspecies israelensis used for the control of dipteran pest insects and Bacillus thuringiensis subspecies tenebrionis and Bacillus thuringiensis subspecies San Diego used for the control of coleopteran pest insects.
  • the isolate which was designated Bacillus thuringiensis subsp. tenebrionis, has been deposited with the German Collection of Microorganisms under accession number DSM 2803. Bacillus thuringiensis subsp. tenebrionis was isolated in 1982 from a dead pupa of the mealworm, Tenebrio molitor (Tenebrionidae, Coleoptera). The strain produces within each cell one spore and one insecticidal parasporal crystal which is of flat plate-like form with an edge length of about 0.8 ⁇ m to 1.5 ⁇ m.
  • Coleopteran active Bacillus thuringiensis has been shown to be an effective control agent for the Colorado potato beetle larvae. After uptake of crystals and spores from coleopteran active Bacillus thuringiensis or isolated crystals larvae, and to a certain extent adults, of the Colorado potato beetle (Leptinotarsa decemlineata) stop feeding. Larvae stages L1-L3 die within 1-3 days (Schnetter et al., in "Fundamental & applied aspects of invertebrate pathology", eds. R.A. Samson et al., Proceedings of the
  • B. thuringiensis subsp. tenebrionis and San Diego has further been confirmed against the elm leaf beetle Xanthogaleruca luteola, and for B. thuringiensis subsp. tenebrionis activity has also been demonstrated against the cereal leaf beetle Oulema melanopa (Lema melanopa(L.)).
  • coleopteran active B. thuringiensis does not exhibit activity towards all insects within the Chrysomelidae. It has for example been found that it has no activity towards the small black flea beetle, Phyllotreta atra and the small striped flea beetle, Phyllotreta undulata, and only minor activity against the banded cucumber beetle, Diabrotica balteata, and the asparagus beetle, Crioseres asparagi.
  • the Colombian leaf beetle Chrysophtharta bimaculata is a major forrest pest responsible for much damage caused by defoliation of eucalyptus trees.
  • coleopteran active B. thuringiensis delta endotoxin exhibits activity towards a Georgian eucalyptus leaf beetle Chrysophtharta bimaculata.
  • This invention consequently relates to the use of coleopteran active B. thuringiensis or its delta endotoxin in controlling the Kenyan eucalyptus leaf beetle Chrysophtharta bimaculata.
  • the present invention also relates to a method of controlling the Georgian eucalyptus leaf beetle Chrysophtharta bimaculata by applying an effective amount of a coleopteran active B. thuringiensis or its delta endotoxin to an area infested by Chrysophtharta bimaculata.
  • the invention further relates to insecticidal compositions for controlling the Colombian eucalyptus leaf beetle Chrysophtharta bimaculata. DETAILED DESCRIPTION OF THE INVENTION
  • the present invention in its first aspect relates to the use of coleopteran active B. thuringiensis products such as, NOVODOR ® , for controlling the Georgian eucalyptus leaf beetle Chrysophtharta bimaculata.
  • the invention in its second aspect relates to a method of controlling the Georgian eucalyptus leaf beetle Chrysophtharta bimaculata by applying an effective amount of a coleopteran active B. thuringiensis product to an area infested with said Kenyan eucalyptus leaf beetle.
  • the expression "effective amount” should be understood as single or repeated applications of from 0.5 1/ha to 8 1/ha of flowable preparations or 0.25 kg/ha to 5 kg/ha of powder or granular preparations.
  • the invention in its third aspect relates to pesticidal compositions or preparations comprising the coleopteran active B. thuringiensis delta endotoxin product in admixture with an agriculturally acceptable diluent or carrier for use in controlling Chrysophtharta bimaculata.
  • compositions of the invention can take any form known in the art for the formulation of agrochemicals, for example, a suspension, a dispersion, an aqueous emulsion, a dusting powder, a dispersible powder, an emulsifiable concentrate or granules. Moreover they can be in a suitable form for direct application or as a concentrate or primary composition which requires dilution with a suitable quantity of water or other diluent before application.
  • the concentration of the insecticidally active B. thuringiensis delta endotoxin in the compositions of the present invention when used alone or in combination with another pesticide, as applied to trees or other plants is preferably within the range from about 0.5 to about 25 per cent by weight, especially 1 to 15 per cent by weight.
  • coleopteran active B. thuringiensis preparation or the compositions of the invention can be applied directly to the tree or other plant by, for example, spraying or dusting at the time when the pest has begun to appear on the tree or plant.
  • the preferred mode of application is by spraying. It is generally important to obtain good control of pests in the early stages of pest development s this most effectively prevents defoliation or other crop damage.
  • the NOVODOR ® FC product is an aqueous flowable concentrate formulated with microbial stabilizers, detergents and suspension aids.
