Abstract Background Brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guenee is the key pest of brinjal that causes a significant yield loss. Farmers spray wide range insecticides right from vegetative stage till last harvesting to protect crop notorious BSFB, which leads pesticide residue insecticide resistance problems. To overcome this, now focus has shifted bio pesticides but their...

The sound-detection method of trunk borer is a very promising in the field forestry prevention and control borers. However, detection accuracy commonly used algorithms often decreases sharply case noise reverberation interference. In practical applications, sound monitoring borers takes place harsh acoustic environment. To solve this problem, we intend to introduce methods which are effective o...

Transgenic rice to control stem borer damage is under development in China. To assess the potential of Bacillus thuringiensis (Bt) transgenes in stem borer control, the toxicity of five Bt protoxins (Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba and Cry1Ca) against two rice stem borers, Sesamia inferens (pink stem borer) and Chilo suppressalis (striped stem borer), was evaluated in the laboratory by feeding n...

Stem borers and leaffolders are the main pests that cause severe damage in rice (Oryza sativa L.) production worldwide. We developed the first photoperiod- and thermo-sensitive male sterility (PTSMS) rice 208S with the cry1Ab/1Ac Bacillus thuringiensis (Bt) gene, through sexual crossing with Huahui 1 (elite line with the cry1Ab/1Ac gene). The novel 208S and its hybrids presented high and stable...

Decomposition of wood is an important part of the carbon cycle of nature. Decomposition is caused by fungi, insects, and marine borers that use the wood as food or shelter, or both. Lignin in wood provides a physical barrier to enzymatic decomposition of cellulose and hemicelluloses. This barrier is breached mechanically by insects and marine borers, biochemically by whiteand soft-rot fungi, an...
