The efficacy of Bacillus thuringiensis, mineral oil, insecticidal emulsion (garlic extract, plant detergent soap and food additive) and insecticidal gel (plant oil and plant extracts) to control the...
Honeybee populations around the world are experiencing a decrease in colony numbers probably due to a combination of different causes, such as diseases, poor nutrition and frequent applications of ins...
Proteins produced by the bacteria Bacillus thuringiensis are widely used for pest control in agriculture and reforestation. Those proteins are produced by genes known as cry genes. Some members of th...
This study was conducted to determine the effect of Bacillus thuringiensis var. kurstaki on the larvae of Thaumetopoea solitaria in the search for an alternative control method with minimal undesirabl...
Bacillus thuringiensis (B.t.) has been widely used in insect biocontrol programs, but the large scale production of this bacillus is expensive because of the high cost of the production processes (med...
Effectiveness of the commercial formulation of Bacillus thuringiensis var. kurstaki “Dipel-2x” on the total protein content and the activity of three haemolymph enzymes acetylcholinesterase (AchE), gl...
Studies were conducted to determine the effectiveness of Bacillus thuringiensis (Dipel ES, Condor OF) Berliner insecticides in controlling the tobacco budworm, Heliothis virescens (F.). Laboratory tes...
The amount of Cry1Ac δ-endotoxin in transgenic Bacillus thuringiensis Berliner (Bt) or Bollgard cotton varies among commercial cultivars. These differences in expression have been correlated with surv...
Field studies were performed during 2005 and 2006 to determine bollworm, Helicoverpa zea (Boddie), and tobacco budworm, Heliothis virescens (F.), larval behavior on conventional non-transgenic cotton ...
European corn borer, Ostrinia nubilalis (Hübner), is susceptible to toxins produced by Bacillus thuringiensis (Berliner), but damage to Bollgard (Bt) cotton (Gossypium hirsutum L.), which produces the...
Native strains of B. thuringiensis were isolated from soil samples collected from different locations and characterized. The various parameters viz., shape, motility, gram reaction, presence of spore...
We evaluated effects of Bacillus thuringiensis subspp. aizawai and kurstaki, in the same concentration as those isolated from sprayed plants at 0, 1, 3 and7 days post spraying, on the biological and ...
The aim of this work is to transfer genes responsible for inducing toxin proteins from some local Bt isolates to the gram-negative E. coli strain using genetic transformation. three local Bt isolates ...
