The entire coding region of the Bacillus thurigiensis HD73 crystal protein gene was subcloned from plasmid pJWK20 into the integration vector pUG2-15. This plasmid expresses chloramphenicol resistance when integrated into the Bacillus subtilis chromosome in the outH locus near the recE region. The correct molecular organization of the integrated plasmid was verified by hybridization to Southern...

Anticarsia gemmatalis Hübner, 1818 is the main soybean defoliating pest in Brazil. The biological control of species done with products based on toxins produced by Bacillus thurigiensis (Bt), as bioinsecticides, or transgenic plants. After activation intestinal proteases, these interact receptors, especially cadherin, leading to death due formation cellular pores. In recent years resistant popu...

In a two-year study, aqueous seed extracts of the neem tree Azadirachta indica A. Juss (Meliaceae) and Bacillus thurigiensis (Bt) were evaluated in the field for the management of pests of okra, Abelmoschus esculentus (L.) Moench. The aqueous neem seed extracts were applied at the rate of 30, 50, 75 and 100 g/l and B.thurigiensis was applied at the rate 1.0 g/l of water. Actellic 25 EC, a synth...

Euadenia eminens Hook f. (Capparaceae) has traditional uses in the management of conjunctivitis, iritis, ophthalmia, tuberculosis, otalgia and rectal prolapse. The fruit pulp is also eaten as an aphrodisiac. In this paper, we report on the anti-inflammatory, antioxidant and antibacterial effects of its roots. A 70 % ethanol extract was tested for anti-inflammatory effect using the carrageenan-i...

The present study was conducted to determine the effects of endophytic bacteria (EB) on some physiological traits and nutrient contents in pepper (Capsicum annuum L.) seedlings grown under drought stress. cv. Mostar F1 two EB isolates [Bacillus thurigiensis (CA41/1) Ochrobactrum sp. (CB36/1)] were employed stress condition. first application at a density 108 CFU mL-1 as 10 mL plant-1 cotyledon ...

Bacillus thuringiensis (B. t.) based formulations have been widely used to control lepidopteran pests in agriculture and forestry. One of their weaknesses is their short residual activity when sprayed in the field. Using Pickering emulsions, mixtures of spores and crystals from three B. t. serovars were successfully encapsulated in colloïdosomal microparticles (50 μm) using innocuous chemicals ...
