NEW STRAIN OF BACILLUS THURINGIENSIS HAVING INSECTICIDAL ACTIVITY AGAINST INSECT PEST OF ORDER DIPTERA

摘要

PURPOSE: To obtain an insecticide for insect pests of the order Diptera, containing a cultured product of a separated new strain of Bacillus thuringiensis as an active ingredient and useful for exterminating the insect pests of the order Diptera such as Telmatoscopus albipunctatus, Anopheles stephensi or Culex pipiens molestus. ;CONSTITUTION: This new strain 73-E-1042 (FERM P-14495) of Bacillus thuringiensis has specific insecticidal activities against insect pests of the order Diptera. Furthermore, an insecticide for the insect pests of the order Diptera contains a cultured product of the separated new strain 73-E-1042 (FERM P-14495) of the Bacillus thuringiensis as an active ingredient at a concentration of about 1×10⁸ to 10¹⁰ spares/ml expressed in terms of spore concentration. The spores which are the active ingredient or a crystalline toxic protein produced by the spores is capable of manifesting specific strong insecticidal activities against the insect pests of the order Diptera such as Telmatoscopus albipunctatus, Anopheles stephens or Culex pipiens molestus.;COPYRIGHT: (C)1996,JPO
