LOCAL PRODUCTION OF PRIMARY POWDER OF BACILLUS THURINGIENSIS SEROTYPE H-14 IN IRAN AND DETERMINATION OF ITS INSECTICIDAL PROPERTIES AGAINST CULEX PIPIENS AND ANOPHELES STEPHENSI

Three media formulated from molasses and cornsteep liquor and another media based on the basal medium formulation of IPS-82 were assessed for the growth and production of insecticidal properties of B. thuringiensis H-14 .• Bacterial powders prepared from the broth cultures were assayed against the larvae of Culex pipiens and Anopheles stephensi. A standard powder of IPS-82 was included in ...

اثر Bacillus thuringiensis H- 14 بر روی لارو آنوفل ها در محیط های زیست طبیعی در جنوب ایران ( کازرون ، فارس)

Field evaluation of the microbial insecticide Bacillus thuringiensis serotype H-14 against floodwater mosquitoes.

Four experimental formulations of the microbial insecticide Bacillus thuringiensis var. israelensis (serotype H-14) were evaluated in the field against larvae of the floodwater mosquitoes Aedes nigromaculis and Psorophora columbiae with ground and aerial application methods. The formulations included ABG-6108D (Abbott Laboratories, North Chicago, Ill.), a wettable powder containing about 400 IU...

Method for determining settling rates of Bacillus thuringiensis serotype H-14 formulations.

A water-column apparatus is described in which settling rates of Bacillus thuringiensis serotype H-14 [B.t. (H-14)] formulations can be indirectly quantified using mortality of mosquito larvae at restricted depths as an index of B.t. (H-14) activity. To illustrate the type of data provided by this method, commercial B.t. (H-14) products (Bactimos, Teknar, Vectobac) and experimental formulations...
