Insecticidal activity of mixtures of Bacillus thuringiensis crystals with plant oils of Sinapis alba and Azadirachta indica

The main purpose of this study was to determine the insecticidal activity of mixtures of Bacillus thuringiensis crystalline toxins and plant substances that could contribute to create a new bioinsecticide of high efficiency. We decided to determine the toxicity of crystals of B. thuringiensis MPU B9 isolate, azadirachtin (NeemAzal), mustard oil and their mixtures against lepidopteran pests: Cydia pomonella , Spodoptera exigua and Dendrolimus...
