Community structure of gut microbes in Busseola fusca (Lepidoptera: Noctuidae)
(2015)Bt-maize is engineered to express insecticidal toxins derived from the bacterium Bacillus thuringiensis and has been shown to be very effective against pests like Busseola fusca.However, resistance of this pest against ... -
The identification of biomarkers to assist in the hydrological characterisation of a chromium polluted mine
(2013)Chromium is used in many processing applications, which has led to the formation of chromium (VI) waste. Cr(VI) is an unstable, mobile carcinogen, which is interchangeable with Cr(III) under certain environmental conditions. ... -
